    `Promise.resolve` returns a promise that will become resolved with the

    promise.then(function(value){

    `Promise.all` accepts an array of promises, and returns a new promise which
    is fulfilled with an array of fulfillment values for the passed promises, or
    rejected with the reason of the first passed promise to be rejected. It casts all
    elements of the passed iterable to promises as it runs this algorithm.
  
    Example:
  
    ```javascript
    let promise1 = resolve(1);
    let promise2 = resolve(2);
    let promise3 = resolve(3);
    let promises = [ promise1, promise2, promise3 ];
  
    Promise.all(promises).then(function(array){
      // The array here would be [ 1, 2, 3 ];
    });
    ```
  
    If any of the `promises` given to `all` are rejected, the first promise
    that is rejected will be given as an argument to the returned promises's
    rejection handler. For example:
  
    Example:
  
    ```javascript
    let promise1 = resolve(1);
    let promise2 = reject(new Error("2"));
    let promise3 = reject(new Error("3"));
    let promises = [ promise1, promise2, promise3 ];
  
    Promise.all(promises).then(function(array){
      // Code here never runs because there are rejected promises!
    }, function(error) {
      // error.message === "2"
    });
    ```

    Example:

      // was resolved.
    });
    ```
  
    `Promise.race` is deterministic in that only the state of the first
    settled promise matters. For example, even if other promises given to the
    `promises` array argument are resolved, but the first settled promise has
    become rejected before the other promises became fulfilled, the returned
    promise will become rejected:
  
    ```javascript
    let promise1 = new Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 1');
      }, 200);
    });
  
    let promise2 = new Promise(function(resolve, reject){
      setTimeout(function(){
        reject(new Error('promise 2'));
      }, 100);
    });
  
    Promise.race([promise1, promise2]).then(function(result){
      // Code here never runs
    }, function(reason){
      // reason.message === 'promise 2' because promise 2 became rejected before
      // promise 1 became fulfilled
    });
    ```
  
    An example real-world use case is implementing timeouts:
  
    ```javascript
    Promise.race([ajax('foo.json'), timeout(5000)])
    ```

    Promise objects represent the eventual result of an asynchronous operation. The
    primary way of interacting with a promise is through its `then` method, which
    registers callbacks to receive either a promise's eventual value or the reason
    why the promise cannot be fulfilled.
  
    Terminology
    -----------
  
    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
    - `thenable` is an object or function that defines a `then` method.
    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
    - `exception` is a value that is thrown using the throw statement.
    - `reason` is a value that indicates why a promise was rejected.
    - `settled` the final resting state of a promise, fulfilled or rejected.
  
    A promise can be in one of three states: pending, fulfilled, or rejected.
  
    Promises that are fulfilled have a fulfillment value and are in the fulfilled
    state.  Promises that are rejected have a rejection reason and are in the
    rejected state.  A fulfillment value is never a thenable.
  
    Promises can also be said to *resolve* a value.  If this value is also a
    promise, then the original promise's settled state will match the value's
    settled state.  So a promise that *resolves* a promise that rejects will
    itself reject, and a promise that *resolves* a promise that fulfills will
    itself fulfill.
  
  
    Basic Usage:
    ------------
  
    ```js
    let promise = new Promise(function(resolve, reject) {
      // on success
      resolve(value);
  
      // on failure
      reject(reason);
    });
  
    promise.then(function(value) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Advanced Usage:
    ---------------
  
    Promises shine when abstracting away asynchronous interactions such as
    `XMLHttpRequest`s.
  
    ```js
    function getJSON(url) {
      return new Promise(function(resolve, reject){
        let xhr = new XMLHttpRequest();
  
        xhr.open('GET', url);
        xhr.onreadystatechange = handler;
        xhr.responseType = 'json';
        xhr.setRequestHeader('Accept', 'application/json');
        xhr.send();
  
        function handler() {
          if (this.readyState === this.DONE) {
            if (this.status === 200) {
              resolve(this.response);
            } else {
              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
            }
          }
        };
      });
    }
  
    getJSON('/posts.json').then(function(json) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Unlike callbacks, promises are great composable primitives.
  
    ```js
    Promise.all([
      getJSON('/posts'),
      getJSON('/comments')
    ]).then(function(values){
      values[0] // => postsJSON
      values[1] // => commentsJSON
  
      return values;
    });
    ```

            var Promise$1 = function () {
              function Promise(resolver) {
                this[PROMISE_ID] = nextId();
                this._result = this._state = undefined;
                this._subscribers = [
                ];
                if (noop !== resolver) {
                  typeof resolver !== 'function' && needsResolver();
                  this instanceof Promise ? initializePromise(this, resolver) : needsNew();
                }
              }              /**
    The primary way of interacting with a promise is through its `then` method,
    which registers callbacks to receive either a promise's eventual value or the
    reason why the promise cannot be fulfilled.
     ```js
    findUser().then(function(user){
      // user is available
    }, function(reason){
      // user is unavailable, and you are given the reason why
    });
    ```
     Chaining
    --------
     The return value of `then` is itself a promise.  This second, 'downstream'
    promise is resolved with the return value of the first promise's fulfillment
    or rejection handler, or rejected if the handler throws an exception.
     ```js
    findUser().then(function (user) {
      return user.name;
    }, function (reason) {
      return 'default name';
    }).then(function (userName) {
      // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
      // will be `'default name'`
    });
     findUser().then(function (user) {
      throw new Error('Found user, but still unhappy');
    }, function (reason) {
      throw new Error('`findUser` rejected and we're unhappy');
    }).then(function (value) {
      // never reached
    }, function (reason) {
      // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
      // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
    });
    ```
    If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
     ```js
    findUser().then(function (user) {
      throw new PedagogicalException('Upstream error');
    }).then(function (value) {
      // never reached
    }).then(function (value) {
      // never reached
    }, function (reason) {
      // The `PedgagocialException` is propagated all the way down to here
    });
    ```
     Assimilation
    ------------
     Sometimes the value you want to propagate to a downstream promise can only be
    retrieved asynchronously. This can be achieved by returning a promise in the
    fulfillment or rejection handler. The downstream promise will then be pending
    until the returned promise is settled. This is called *assimilation*.
     ```js
    findUser().then(function (user) {
      return findCommentsByAuthor(user);
    }).then(function (comments) {
      // The user's comments are now available
    });
    ```
     If the assimliated promise rejects, then the downstream promise will also reject.
     ```js
    findUser().then(function (user) {
      return findCommentsByAuthor(user);
    }).then(function (comments) {
      // If `findCommentsByAuthor` fulfills, we'll have the value here
    }, function (reason) {
      // If `findCommentsByAuthor` rejects, we'll have the reason here
    });
    ```
     Simple Example
    --------------
     Synchronous Example
     ```javascript
    let result;
     try {
      result = findResult();
      // success
    } catch(reason) {
      // failure
    }
    ```
     Errback Example
     ```js
    findResult(function(result, err){
      if (err) {
        // failure
      } else {
        // success
      }
    });
    ```
     Promise Example;

          // addressed by a short id (herein called output code).  All data is
          // referenced by a code, which represents one or more values from the
          // original input stream.  All input bytes can be referenced as the same
          // value as an output code.  So if you didn't want any compression, you
          // could more or less just output the original bytes as codes (there are
          // some details to this, but it is the idea).  In order to achieve
          // compression, values greater then the input range (codes can be up to
          // 12-bit while input only 8-bit) represent a sequence of previously seen
          // inputs.  The decompressor is able to build the same mapping while
          // decoding, so there is always a shared common knowledge between the
          // encoding and decoder, which is also important for "timing" aspects like
          // how to handle variable bit width code encoding.
          //
          // One obvious but very important consequence of the table system is there
          // is always a unique id (at most 12-bits) to map the runs.  'A' might be
          // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc.  This relationship
          // can be used for an effecient lookup strategy for the code mapping.  We
          // need to know if a run has been seen before, and be able to map that run
          // to the output code.  Since we start with known unique ids (input bytes),
          // and then from those build more unique ids (table entries), we can
          // continue this chain (almost like a linked list) to always have small
          // integer values that represent the current byte chains in the encoder.
          // This means instead of tracking the input bytes (AAAABCD) to know our
          // current state, we can track the table entry for AAAABC (it is guaranteed
          // to exist by the nature of the algorithm) and the next character D.
          // Therefor the tuple of (table_entry, byte) is guaranteed to also be
          // unique.  This allows us to create a simple lookup key for mapping input
          // sequences to codes (table indices) without having to store or search
          // any of the code sequences.  So if 'AAAA' has a table entry of 12, the
          // tuple of ('AAAA', K) for any input byte K will be unique, and can be our
          // key.  This leads to a integer value at most 20-bits, which can always

  *
  * (c) 2017 Axel Kittenberger
  *
  * This interpreter has been implemented according to this documentation:
  * https://developer.apple.com/fonts/TrueType-Reference-Manual/RM05/Chap5.html
  *
  * According to the documentation F24DOT6 values are used for pixels.
  * That means calculation is 1/64 pixel accurate and uses integer operations.
  * However, Javascript has floating point operations by default and only
  * those are available. One could make a case to simulate the 1/64 accuracy
  * exactly by truncating after every division operation
  * (for example with << 0) to get pixel exactly results as other TrueType
  * implementations. It may make sense since some fonts are pixel optimized
  * by hand using DELTAP instructions. The current implementation doesn't
  * and rather uses full floating point precision.
  *
  * xScale, yScale and rotation is currently ignored.
  *
  * A few non-trivial instructions are missing as I didn't encounter yet
  * a font that used them to test a possible implementation.
  *
  * Some fonts seem to use undocumented features regarding the twilight zone.
  * Only some of them are implemented as they were encountered.
  *
  * The exports.DEBUG statements are removed on the minified distribution file.

  	INTERPOLATE:
  ============
  	Examples of point interpolation.
  	The weight of the movement of the reference point gets bigger
  the further the other reference point is away, thus the safest
  option (that is avoiding 0/0 divisions) is to weight the
  original distance of the other point by the sum of both distances.
  	If the sum of both distances is 0, then move the point by the
  arithmetic average of the movement of both reference points.

 * Creates a screen reader-accessible description of shapes on the canvas.
 *
 * `textOutput()` adds a general description, list of shapes, and
 * table of shapes to the web page. The general description includes the
 * canvas size, canvas color, and number of shapes. For example,
 * `Your output is a, 100 by 100 pixels, gray canvas containing the following 2 shapes:`.
 *
 * A list of shapes follows the general description. The list describes the
 * color, location, and area of each shape. For example,
 * `a red circle at middle covering 3% of the canvas`. Each shape can be
 * selected to get more details.
 *
 * `textOutput()` uses its table of shapes as a list. The table describes the
 * shape, color, location, coordinates and area. For example,
 * `red circle location = middle area = 3%`. This is different from
 * <a href="#/p5/gridOutput">gridOutput()</a>, which uses its table as a grid.
 *
 * The `display` parameter is optional. It determines how the description is
 * displayed. If `LABEL` is passed, as in `textOutput(LABEL)`, the description
 * will be visible in a div element next to the canvas. Using `LABEL` creates
 * unhelpful duplicates for screen readers. Only use `LABEL` during
 * development. If `FALLBACK` is passed, as in `textOutput(FALLBACK)`, the
 * description will only be visible to screen readers. This is the default
 * mode.
 *
 * Read
 * <a href="/learn/accessible-labels.html">Writing accessible canvas descriptions</a>
 * to learn more about making sketches accessible.

        /**
 * Creates a screen reader-accessible description of shapes on the canvas.
 *
 * `gridOutput()` adds a general description, table of shapes, and list of
 * shapes to the web page. The general description includes the canvas size,
 * canvas color, and number of shapes. For example,
 * `gray canvas, 100 by 100 pixels, contains 2 shapes:  1 circle 1 square`.
 *
 * `gridOutput()` uses its table of shapes as a grid. Each shape in the grid
 * is placed in a cell whose row and column correspond to the shape's location
 * on the canvas. The grid cells describe the color and type of shape at that
 * location. For example, `red circle`. These descriptions can be selected
 * individually to get more details. This is different from
 * <a href="#/p5/textOutput">textOutput()</a>, which uses its table as a list.
 *
 * A list of shapes follows the table. The list describes the color, type,
 * location, and area of each shape. For example,
 * `red circle, location = middle, area = 3 %`.
 *
 * The `display` parameter is optional. It determines how the description is
 * displayed. If `LABEL` is passed, as in `gridOutput(LABEL)`, the description
 * will be visible in a div element next to the canvas. Using `LABEL` creates
 * unhelpful duplicates for screen readers. Only use `LABEL` during
 * development. If `FALLBACK` is passed, as in `gridOutput(FALLBACK)`, the
 * description will only be visible to screen readers. This is the default
 * mode.
 *
 * Read
 * <a href="/learn/accessible-labels.html">Writing accessible canvas descriptions</a>
 * to learn more about making sketches accessible.

 * Gets the saturation value of a color.
 *
 * `saturation()` extracts the saturation value from a
 * <a href="#/p5.Color">p5.Color</a> object, an array of color components, or
 * a CSS color string.
 *
 * Saturation is scaled differently in HSB and HSL. By default, `saturation()`
 * returns a color's HSL saturation in the range 0 to 100. If the
 * <a href="#/colorMode">colorMode()</a> is set to HSB or HSL, it returns the
 * saturation value in the given mode.
 *
 * @method saturation
 * @param {p5.Color|Number[]|String} color <a href="#/p5.Color">p5.Color</a> object, array of
 *                                         color components, or CSS color string.

 * of four ways. If the parameter is a `Number`, it's interpreted as a grayscale
 * value. If the parameter is a `String`, it's interpreted as a CSS color string.
 * RGB, RGBA, HSL, HSLA, hex, and named color strings are supported. If the
 * parameter is a <a href="#/p5.Color">p5.Color</a> object, it will be used as
 * the background color. If the parameter is a
 * <a href="#/p5.Image">p5.Image</a> object, it will be used as the background
 * image.
 *
 * The version of `background()` with two parameters interprets the first one
 * as a grayscale value. The second parameter sets the alpha (transparency)
 * value.
 *
 * The version of `background()` with three parameters interprets them as RGB,
 * HSB, or HSL colors, depending on the current
 * <a href="#/p5/colorMode">colorMode()</a>. By default, colors are specified
 * in RGB values. Calling `background(255, 204, 0)` sets the background a bright
 * yellow color.

 * One of the two render modes in p5.js, used for computationally intensive tasks like 3D rendering and shaders.
 *
 * `WEBGL` differs from the default <a href="/reference/#/p5/P2D">`P2D`</a> renderer in the following ways:
 *
 * - **Coordinate System** - When drawing in `WEBGL` mode, the origin point (0,0,0) is located at the center of the screen, not the top-left corner. See <a href="https://p5js.org/learn/getting-started-in-webgl-coords-and-transform.html">the learn page about coordinates and transformations</a>.
 * - **3D Shapes** - `WEBGL` mode can be used to draw 3-dimensional shapes like <a href="/reference/#/p5/box">box()</a>, <a href="/reference/#/p5/sphere">sphere()</a>, <a href="/reference/#/p5/cone">cone()</a>, and <a href="/#Shape3D%20Primitives">more</a>. See <a href="https://p5js.org/learn/getting-started-in-webgl-custom-geometry.html">the learn page about custom geometry</a> to make more complex objects.
 * - **Shape Detail** - When drawing in `WEBGL` mode, you can specify how smooth curves should be drawn by using a `detail` parameter. See <a href="https://github.com/processing/p5.js/wiki/Getting-started-with-WebGL-in-p5#3d-primitives-shapes">the wiki section about shapes</a> for a more information and an example.
 * - **Textures** - A texture is like a skin that wraps onto a shape. See <a href="https://github.com/processing/p5.js/wiki/Getting-started-with-WebGL-in-p5#textures">the wiki section about textures</a> for examples of mapping images onto surfaces with textures.
 * - **Materials and Lighting** - `WEBGL` offers different types of lights like <a href="/reference/#/p5/ambientLight">ambientLight()</a> to place around a scene. Materials like <a href="/reference/#/p5/specularMaterial">specularMaterial()</a> reflect the lighting to convey shape and depth. See <a href="https://p5js.org/learn/getting-started-in-webgl-appearance.html">the learn page for styling and appearance</a> to experiment with different combinations.
 * - **Camera** - The viewport of a `WEBGL` sketch can be adjusted by changing camera attributes. See <a href="https://p5js.org/learn/getting-started-in-webgl-appearance.html#camera">the learn page section about cameras</a> for an explanation of camera controls.
 * - **Text** - `WEBGL` requires opentype/truetype font files to be preloaded using <a href="/reference/#/p5/loadFont">loadFont()</a>. See <a href="https://github.com/processing/p5.js/wiki/Getting-started-with-WebGL-in-p5#text">the wiki section about text</a> for details, along with a workaround.
 * - **Shaders** - Shaders are hardware accelerated programs that can be used for a variety of effects and graphics. See the <a href="https://p5js.org/learn/getting-started-in-webgl-shaders.html">introduction to shaders</a> to get started with shaders in p5.js.
 * - **Graphics Acceleration** - `WEBGL` mode uses the graphics card instead of the CPU, so it may help boost the performance of your sketch (example: drawing more shapes on the screen at once).
 *
 * To learn more about WEBGL mode, check out <a href="https://p5js.org/learn/#:~:text=Getting%20Started%20in%20WebGL">all the interactive WEBGL tutorials</a> in the "Learn" section of this website, or read the wiki article <a href="https://github.com/processing/p5.js/wiki/Getting-started-with-WebGL-in-p5">"Getting started with WebGL in p5"</a>.

   * This is the main file for the Friendly Error System (FES), containing
   * the core as well as miscellaneous functionality of the FES. Here is a
   * brief outline of the functions called in this system.
   *
   * The FES may be invoked by a call to either
   * (1) _validateParameters, (2) _friendlyFileLoadError, (3) _friendlyError,
   * (4) helpForMisusedAtTopLevelCode, or (5) _fesErrorMonitor.
   *
   * _validateParameters is located in validate_params.js along with other code
   * used for parameter validation.
   * _friendlyFileLoadError is located in file_errors.js along with other code
   * used for dealing with file load errors.
   * Apart from this, there's also a file stacktrace.js, which contains the code
   * to parse the error stack, borrowed from:
   * https://github.com/stacktracejs/stacktrace.js
   *
   * For more detailed information on the FES functions, including the call
   * sequence of each function, please look at the FES Reference + Dev Notes:

     * A function that's called once when the sketch begins running.

     * Declaring the function `setup()` sets a code block to run once
     * automatically when the sketch starts running. It's used to perform
     * setup tasks such as creating the canvas and initializing variables:
     *
     * ```js
     * function setup() {
     *   // Code to run once at the start of the sketch.
     * }
     * ```
     *
     * Code placed in `setup()` will run once before code placed in
     * <a href="#/p5/draw">draw()</a> begins looping. If the
     * <a href="#/p5/preload">preload()</a> is declared, then `setup()` will
     * run immediately after <a href="#/p5/preload">preload()</a> finishes
     * loading assets.
     *
     * Note: `setup()` doesn’t have to be declared, but it’s common practice to do so.
     *
     * @method setup

     * A function that's called repeatedly while the sketch runs.
     *
     * Declaring the function `draw()` sets a code block to run repeatedly
     * once the sketch starts. It’s used to create animations and respond to
     * user inputs:
     *
     * ```js
     * function draw() {
     *   // Code to run repeatedly.
     * }
     * ```
     *
     * This is often called the "draw loop" because p5.js calls the code in
     * `draw()` in a loop behind the scenes. By default, `draw()` tries to run
     * 60 times per second. The actual rate depends on many factors. The
     * drawing rate, called the "frame rate", can be controlled by calling
     * <a href="#/p5/frameRate">frameRate()</a>. The number of times `draw()`
     * has run is stored in the system variable
     * <a href="#/p5/frameCount">frameCount()</a>.
     *
     * Code placed within `draw()` begins looping after
     * <a href="#/p5/setup">setup()</a> runs. `draw()` will run until the user
     * closes the sketch. `draw()` can be stopped by calling the
     * <a href="#/p5/noLoop">noLoop()</a> function. `draw()` can be resumed by
     * calling the <a href="#/p5/loop">loop()</a> function.

 * A class to describe a drawing surface that's separate from the main canvas.
 *
 * Each `p5.Graphics` object provides a dedicated drawing surface called a
 * *graphics buffer*. Graphics buffers are helpful when drawing should happen
 * offscreen. For example, separate scenes can be drawn offscreen and
 * displayed only when needed.
 *
 * `p5.Graphics` objects have nearly all the drawing features of the main
 * canvas. For example, calling the method `myGraphics.circle(50, 50, 20)`
 * draws to the graphics buffer. The resulting image can be displayed on the
 * main canvas by passing the `p5.Graphics` object to the
 * <a href="#/p5/image">image()</a> function, as in `image(myGraphics, 0, 0)`.
 *
 * Note: <a href="#/p5/createGraphics">createGraphics()</a> is the recommended
 * way to create an instance of this class.
 *
 * @class p5.Graphics
 * @constructor
 * @extends p5.Element
 * @param {Number} width width of the graphics buffer in pixels.
 * @param {Number} height height of the graphics buffer in pixels.
 * @param {Constant} renderer renderer to use, either P2D or WEBGL.
 * @param {p5} [pInst] sketch instance.
 * @param {HTMLCanvasElement} [canvas] existing `&lt;canvas&gt;` element to use.
 *
 * @example
 * <div>
 * <code>
 * let pg;
 *
 * function setup() {
 *   createCanvas(100, 100);
 *
 *   // Create a p5.Graphics object.

 *
 *   // Draw to the p5.Graphics object.
 *   pg.background(100);
 *   pg.circle(25, 25, 20);
 *
 *   describe('A dark gray square with a white circle at its center drawn on a gray background.');
 * }

     * as the graphics buffer makes this speedup possible.
     *
     * The parameter, `options`, is optional. An object can be passed to configure
     * the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. The available
     * properties are:
     *
     * - `format`: data format of the texture, either `UNSIGNED_BYTE`, `FLOAT`, or `HALF_FLOAT`. Default is `UNSIGNED_BYTE`.
     * - `channels`: whether to store `RGB` or `RGBA` color channels. Default is to match the graphics buffer which is `RGBA`.
     * - `depth`: whether to include a depth buffer. Default is `true`.
     * - `depthFormat`: data format of depth information, either `UNSIGNED_INT` or `FLOAT`. Default is `FLOAT`.
     * - `stencil`: whether to include a stencil buffer for masking. `depth` must be `true` for this feature to work. Defaults to the value of `depth` which is `true`.
     * - `antialias`: whether to perform anti-aliasing. If set to `true`, as in `{ antialias: true }`, 2 samples will be used by default. The number of samples can also be set, as in `{ antialias: 4 }`. Default is to match <a href="#/p5/setAttributes">setAttributes()</a> which is `false` (`true` in Safari).
     * - `width`: width of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the graphics buffer width.
     * - `height`: height of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the graphics buffer height.
     * - `density`: pixel density of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the graphics buffer pixel density.
     * - `textureFiltering`: how to read values from the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Either `LINEAR` (nearby pixels will be interpolated) or `NEAREST` (no interpolation). Generally, use `LINEAR` when using the texture as an image and `NEAREST` if reading the texture as data. Default is `LINEAR`.
     *
     * If the `width`, `height`, or `density` attributes are set, they won't
     * automatically match the graphics buffer and must be changed manually.

 * Creates a canvas element on the web page.
 *
 * `createCanvas()` creates the main drawing canvas for a sketch. It should
 * only be called once at the beginning of <a href="#/p5/setup">setup()</a>.
 * Calling `createCanvas()` more than once causes unpredictable behavior.
 *
 * The first two parameters, `width` and `height`, are optional. They set the
 * dimensions of the canvas and the values of the
 * <a href="#/p5/width">width</a> and <a href="#/p5/height">height</a> system
 * variables. For example, calling `createCanvas(900, 500)` creates a canvas
 * that's 900×500 pixels. By default, `width` and `height` are both 100.
 *
 * The third parameter is also optional. If either of the constants `P2D` or
 * `WEBGL` is passed, as in `createCanvas(900, 500, WEBGL)`, then it will set
 * the sketch's rendering mode. If an existing
 * <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement" target="_blank">HTMLCanvasElement</a>
 * is passed, as in `createCanvas(900, 500, myCanvas)`, then it will be used
 * by the sketch.
 *
 * The fourth parameter is also optional. If an existing
 * <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement" target="_blank">HTMLCanvasElement</a>
 * is passed, as in `createCanvas(900, 500, WEBGL, myCanvas)`, then it will be
 * used by the sketch.
 *
 * Note: In WebGL mode, the canvas will use a WebGL2 context if it's supported
 * by the browser. Check the <a href="#/p5/webglVersion">webglVersion</a>
 * system variable to check what version is being used, or call
 * `setAttributes({ version: 1 })` to create a WebGL1 context.
 *
 * @method createCanvas
 * @param  {Number} [width] width of the canvas. Defaults to 100.
 * @param  {Number} [height] height of the canvas. Defaults to 100.
 * @param  {Constant} [renderer] either P2D or WEBGL. Defaults to `P2D`.
 * @param  {HTMLCanvasElement} [canvas] existing canvas element that should be used for the sketch.
 * @return {p5.Renderer} new `p5.Renderer` that holds the canvas.
 *

 * <div>
 * <code>

 * - `format`: data format of the texture, either `UNSIGNED_BYTE`, `FLOAT`, or `HALF_FLOAT`. Default is `UNSIGNED_BYTE`.
 * - `channels`: whether to store `RGB` or `RGBA` color channels. Default is to match the main canvas which is `RGBA`.
 * - `depth`: whether to include a depth buffer. Default is `true`.
 * - `depthFormat`: data format of depth information, either `UNSIGNED_INT` or `FLOAT`. Default is `FLOAT`.
 * - `stencil`: whether to include a stencil buffer for masking. `depth` must be `true` for this feature to work. Defaults to the value of `depth` which is `true`.
 * - `antialias`: whether to perform anti-aliasing. If set to `true`, as in `{ antialias: true }`, 2 samples will be used by default. The number of samples can also be set, as in `{ antialias: 4 }`. Default is to match <a href="#/p5/setAttributes">setAttributes()</a> which is `false` (`true` in Safari).
 * - `width`: width of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the main canvas width.
 * - `height`: height of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the main canvas height.
 * - `density`: pixel density of the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Default is to always match the main canvas pixel density.
 * - `textureFiltering`: how to read values from the <a href="#/p5.Framebuffer">p5.Framebuffer</a> object. Either `LINEAR` (nearby pixels will be interpolated) or `NEAREST` (no interpolation). Generally, use `LINEAR` when using the texture as an image and `NEAREST` if reading the texture as data. Default is `LINEAR`.

 * Sets the way colors blend when added to the canvas.
 *
 * By default, drawing with a solid color paints over the current pixel values
 * on the canvas. `blendMode()` offers many options for blending colors.
 *
 * Shapes, images, and text can be used as sources for drawing to the canvas.
 * A source pixel changes the color of the canvas pixel where it's drawn. The
 * final color results from blending the source pixel's color with the canvas
 * pixel's color. RGB color values from the source and canvas pixels are
 * compared, added, subtracted, multiplied, and divided to create different
 * effects. Red values with red values, greens with greens, and blues with
 * blues.
 *
 * The parameter, `mode`, sets the blend mode. For example, calling
 * `blendMode(ADD)` sets the blend mode to `ADD`. The following blend modes
 * are available in both 2D and WebGL mode:
 *
 * - `BLEND`: color values from the source overwrite the canvas. This is the default mode.
 * - `ADD`: color values from the source are added to values from the canvas.
 * - `DARKEST`: keeps the darkest color value.
 * - `LIGHTEST`: keeps the lightest color value.
 * - `EXCLUSION`: similar to `DIFFERENCE` but with less contrast.
 * - `MULTIPLY`: color values from the source are multiplied with values from the canvas. The result is always darker.
 * - `SCREEN`: all color values are inverted, then multiplied, then inverted again. The result is always lighter. (Opposite of `MULTIPLY`)
 * - `REPLACE`: the last source drawn completely replaces the rest of the canvas.
 * - `REMOVE`: overlapping pixels are removed by making them completely transparent.
 *
 * The following blend modes are only available in 2D mode:
 *
 * - `DIFFERENCE`: color values from the source are subtracted from the values from the canvas. If the difference is a negative number, it's made positive.
 * - `OVERLAY`: combines `MULTIPLY` and `SCREEN`. Dark values in the canvas get darker and light values get lighter.
 * - `HARD_LIGHT`: combines `MULTIPLY` and `SCREEN`. Dark values in the source get darker and light values get lighter.
 * - `SOFT_LIGHT`: a softer version of `HARD_LIGHT`.
 * - `DODGE`: lightens light tones and increases contrast. Divides the canvas color values by the inverted color values from the source.
 * - `BURN`: darkens dark tones and increases contrast. Divides the source color values by the inverted color values from the canvas, then inverts the result.
 *
 * The following blend modes are only available in WebGL mode:
 *
 * - `SUBTRACT`: RGB values from the source are subtracted from the values from the canvas. If the difference is a negative number, it's made positive. Alpha (transparency) values from the source and canvas are added.

 *      this, the angles become arbitrary when width != height: 45 degrees
 *      might be drawn at 5 degrees on a 'wide' ellipse, or at 85 degrees on

 * Draws an arc.
 *
 * An arc is a section of an ellipse defined by the `x`, `y`, `w`, and
 * `h` parameters. `x` and `y` set the location of the arc's center. `w` and
 * `h` set the arc's width and height. See
 * <a href="#/p5/ellipse">ellipse()</a> and
 * <a href="#/p5/ellipseMode">ellipseMode()</a> for more details.
 *
 * The fifth and sixth parameters, `start` and `stop`, set the angles
 * between which to draw the arc. Arcs are always drawn clockwise from
 * `start` to `stop`. Angles are always given in radians.
 *
 * The seventh parameter, `mode`, is optional. It determines the arc's fill
 * style. The fill modes are a semi-circle (`OPEN`), a closed semi-circle
 * (`CHORD`), or a closed pie segment (`PIE`).
 *
 * The eighth parameter, `detail`, is also optional. It determines how many
 * vertices are used to draw the arc in WebGL mode. The default value is 25.
 *
 * @method arc
 * @param  {Number} x      x-coordinate of the arc's ellipse.
 * @param  {Number} y      y-coordinate of the arc's ellipse.
 * @param  {Number} w      width of the arc's ellipse by default.
 * @param  {Number} h      height of the arc's ellipse by default.
 * @param  {Number} start  angle to start the arc, specified in radians.
 * @param  {Number} stop   angle to stop the arc, specified in radians.
 * @param  {Constant} [mode] optional parameter to determine the way of drawing
 *                         the arc. either CHORD, PIE, or OPEN.
 * @param  {Integer} [detail] optional parameter for WebGL mode only. This is to
 *                         specify the number of vertices that makes up the
 *                         perimeter of the arc. Default value is 25. Won't
 *                         draw a stroke for a detail of more than 50.

 * Draws a quadrilateral (four-sided shape).

 * first pair of parameters `(x1, y1)` sets the quad's first point. The next
 * three pairs of parameters set the coordinates for its next three points
 * `(x2, y2)`, `(x3, y3)`, and `(x4, y4)`. Points should be added in either
 * clockwise or counter-clockwise order.
 *
 * The version of `quad()` with twelve parameters allows the quad to be drawn
 * in 3D space. Doing so requires adding the `WEBGL` argument to
 * <a href="#/p5/createCanvas">createCanvas()</a>.
 *
 * The thirteenth and fourteenth parameters are optional. In WebGL mode, they
 * set the number of segments used to draw the quadrilateral in the x- and
 * y-directions. They're both 2 by default.
 *
 * @method quad
 * @param {Number} x1 the x-coordinate of the first point.
 * @param {Number} y1 the y-coordinate of the first point.
 * @param {Number} x2 the x-coordinate of the second point.

 * Begins adding vertices to a custom shape.

 * allow for creating custom shapes in 2D or 3D. `beginShape()` begins adding
 * vertices to a custom shape and <a href="#/p5/endShape">endShape()</a> stops
 * adding them.
 *
 * The parameter, `kind`, sets the kind of shape to make. By default, any
 * irregular polygon can be drawn. The available modes for kind are:
 *
 * - `POINTS` to draw a series of points.
 * - `LINES` to draw a series of unconnected line segments.
 * - `TRIANGLES` to draw a series of separate triangles.
 * - `TRIANGLE_FAN` to draw a series of connected triangles sharing the first vertex in a fan-like fashion.
 * - `TRIANGLE_STRIP` to draw a series of connected triangles in strip fashion.
 * - `QUADS` to draw a series of separate quadrilaterals (quads).
 * - `QUAD_STRIP` to draw quad strip using adjacent edges to form the next quad.
 * - `TESS` to create a filling curve by explicit tessellation (WebGL only).
 *
 * After calling `beginShape()`, shapes can be built by calling
 * <a href="#/p5/vertex">vertex()</a>,
 * <a href="#/p5/bezierVertex">bezierVertex()</a>,
 * <a href="#/p5/quadraticVertex">quadraticVertex()</a>, and/or
 * <a href="#/p5/curveVertex">curveVertex()</a>. Calling
 * <a href="#/p5/endShape">endShape()</a> will stop adding vertices to the
 * shape. Each shape will be outlined with the current stroke color and filled
 * with the current fill color.

 * called between the

 * the previous vertex as the first anchor point, so there must be at least

 * be used.
 *
 * The first four parameters, `x2`, `y2`, `x3`, and `y3`, set the curve’s two

 * Adds a spline curve segment to a custom shape.
 *
 * `curveVertex()` adds a curved segment to custom shapes. The spline curves
 * it creates are defined like those made by the
 * <a href="#/p5/curve">curve()</a> function. `curveVertex()` must be called
 * between the <a href="#/p5/beginShape">beginShape()</a> and
 * <a href="#/p5/endShape">endShape()</a> functions.
 *
 * Spline curves can form shapes and curves that slope gently. They’re like
 * cables that are attached to a set of points. Splines are defined by two
 * anchor points and two control points. `curveVertex()` must be called at
 * least four times between
 * <a href="#/p5/beginShape">beginShape()</a> and
 * <a href="#/p5/endShape">endShape()</a> in order to draw a curve:
 *
 * ```js
 * beginShape();
 *
 * // Add the first control point.
 * curveVertex(84, 91);
 *
 * // Add the anchor points to draw between.
 * curveVertex(68, 19);
 * curveVertex(21, 17);
 *
 * // Add the second control point.
 * curveVertex(32, 91);
 *
 * endShape();
 * ```
 *
 * The code snippet above would only draw the curve between the anchor points,
 * similar to the <a href="#/p5/curve">curve()</a> function. The segments
 * between the control and anchor points can be drawn by calling
 * `curveVertex()` with the coordinates of the control points:
 *
 * ```js
 * beginShape();
 *
 * // Add the first control point and draw a segment to it.
 * curveVertex(84, 91);
 * curveVertex(84, 91);
 *
 * // Add the anchor points to draw between.
 * curveVertex(68, 19);
 * curveVertex(21, 17);
 *
 * // Add the second control point.
 * curveVertex(32, 91);
 *
 * // Uncomment the next line to draw the segment to the second control point.
 * // curveVertex(32, 91);
 *
 * endShape();
 * ```
 *
 * The first two parameters, `x` and `y`, set the vertex’s location. For
 * example, calling `curveVertex(10, 10)` adds a point to the curve at
 * `(10, 10)`.
 *
 * Spline curves can also be drawn in 3D using WebGL mode. The 3D version of
 * `curveVertex()` has three arguments because each point has x-, y-, and
 * z-coordinates. By default, the vertex’s z-coordinate is set to 0.
 *
 * Note: `curveVertex()` won’t work when an argument is passed to
 * <a href="#/p5/beginShape">beginShape()</a>.

 * Adds a quadratic Bézier curve segment to a custom shape.
 *
 * `quadraticVertex()` adds a curved segment to custom shapes. The Bézier
 * curve segments it creates are similar to those made by the
 * <a href="#/p5/bezierVertex">bezierVertex()</a> function.
 * `quadraticVertex()` must be called between the
 * <a href="#/p5/beginShape">beginShape()</a> and
 * <a href="#/p5/endShape">endShape()</a> functions. The curved segment uses
 * the previous vertex as the first anchor point, so there must be at least
 * one call to <a href="#/p5/vertex">vertex()</a> before `quadraticVertex()` can
 * be used.
 *
 * The first two parameters, `cx` and `cy`, set the curve’s control point.
 * The control point "pulls" the curve towards its.
 *
 * The last two parameters, `x3`, and `y3`, set the last anchor point. The
 * last anchor point is where the curve ends.
 *
 * Bézier curves can also be drawn in 3D using WebGL mode. The 3D version of
 * `bezierVertex()` has eight arguments because each point has x-, y-, and
 * z-coordinates.
 *
 * Note: `quadraticVertex()` won’t work when an argument is passed to
 * <a href="#/p5/beginShape">beginShape()</a>.
 *
 * @method quadraticVertex
 * @param  {Number} cx x-coordinate of the control point.
 * @param  {Number} cy y-coordinate of the control point.
 * @param  {Number} x3 x-coordinate of the anchor point.

 *
 * 3D shapes created with <a href="#/p5/beginShape">beginShape()</a> and

 * points called vertices. Each vertex added with

 *
 * `normal()` can be called two ways with different parameters to define the
 * normal vector's components.
 *
 * The first way to call `normal()` has three parameters, `x`, `y`, and `z`.
 * If `Number`s are passed, as in `normal(1, 2, 3)`, they set the x-, y-, and
 * z-components of the normal vector.
 *
 * The second way to call `normal()` has one parameter, `vector`. If a
 * <a href="#/p5.Vector">p5.Vector</a> object is passed, as in
 * `normal(myVector)`, its components will be used to set the normal vector.
 *
 * `normal()` changes the normal vector of vertices added to a custom shape
 * with <a href="#/p5/vertex">vertex()</a>. `normal()` must be called between
 * the <a href="#/p5/beginShape">beginShape()</a> and
 * <a href="#/p5/endShape">endShape()</a> functions, just like
 * <a href="#/p5/vertex">vertex()</a>. The normal vector set by calling
 * `normal()` will affect all following vertices until `normal()` is called
 * again:
 *
 * ```js
 * beginShape();
 *
 * // Set the vertex normal.
 * normal(-0.4, -0.4, 0.8);

        /**
 * Creates a new sketch in "instance" mode.
 *
 * All p5.js sketches are instances of the `p5` class. Put another way, all
 * p5.js sketches are objects with methods including `pInst.setup()`,
 * `pInst.draw()`, `pInst.circle()`, and `pInst.fill()`. By default, sketches
 * run in "global mode" to hide some of this complexity.
 *
 * In global mode, a default instance of the `p5` class is created
 * automatically. The default `p5` instance searches the web page's source
 * code for declarations of system functions such as `setup()`, `draw()`,
 * and `mousePressed()`, then attaches those functions to itself as methods.
 * Calling a function such as `circle()` in global mode actually calls the
 * default `p5` object's `pInst.circle()` method.
 *
 * It's often helpful to isolate the code within sketches from the rest of the
 * code on a web page. Two common use cases are web pages that use other
 * JavaScript libraries and web pages with multiple sketches. "Instance mode"
 * makes it easy to support both of these scenarios.
 *
 * Instance mode sketches support the same API as global mode sketches. They
 * use a function to bundle, or encapsulate, an entire sketch. The function
 * containing the sketch is then passed to the `p5()` constructor.
 *
 * The first parameter, `sketch`, is a function that contains the sketch. For
 * example, the statement `new p5(mySketch)` would create a new instance mode
 * sketch from a function named `mySketch`. The function should have one
 * parameter, `p`, that's a `p5` object.
 *
 * The second parameter, `node`, is optional. If a string is passed, as in
 * `new p5(mySketch, 'sketch-one')` the new instance mode sketch will become a
 * child of the HTML element with the id `sketch-one`. If an HTML element is
 * passed, as in `new p5(mySketch, myElement)`, then the new instance mode
 * sketch will become a child of the `Element` object called `myElement`.
 *
 * @method p5
 * @param {Object} sketch function containing the sketch.
 * @param {String|HTMLElement} node ID or reference to the HTML element that will contain the sketch.

 * Applies a transformation matrix to the coordinate system.
 *
 * Transformations such as
 * <a href="#/p5/translate">translate()</a>,
 * <a href="#/p5/rotate">rotate()</a>, and
 * <a href="#/p5/scale">scale()</a>
 * use matrix-vector multiplication behind the scenes. A table of numbers,
 * called a matrix, encodes each transformation. The values in the matrix
 * then multiply each point on the canvas, which is represented by a vector.
 *
 * `applyMatrix()` allows for many transformations to be applied at once. See
 * <a href="https://en.wikipedia.org/wiki/Transformation_matrix" target="_blank">Wikipedia</a>
 * and <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Matrix_math_for_the_web" target="_blank">MDN</a>
 * for more details about transformations.
 *
 * There are two ways to call `applyMatrix()` in two and three dimensions.
 *
 * In 2D mode, the parameters `a`, `b`, `c`, `d`, `e`, and `f`, correspond to
 * elements in the following transformation matrix:
 *
 * > <img style="max-width: 150px" src="assets/transformation-matrix.png"
 * alt="The transformation matrix used when applyMatrix is called in 2D mode."/>
 *
 * The numbers can be passed individually, as in
 * `applyMatrix(2, 0, 0, 0, 2, 0)`. They can also be passed in an array, as in
 * `applyMatrix([2, 0, 0, 0, 2, 0])`.
 *
 * In 3D mode, the parameters `a`, `b`, `c`, `d`, `e`, `f`, `g`, `h`, `i`,
 * `j`, `k`, `l`, `m`, `n`, `o`, and `p` correspond to elements in the
 * following transformation matrix:
 *
 * <img style="max-width: 300px" src="assets/transformation-matrix-4-4.png"
 * alt="The transformation matrix used when applyMatrix is called in 3D mode."/>
 *
 * The numbers can be passed individually, as in
 * `applyMatrix(2, 0, 0, 0, 0, 2, 0, 0, 0, 0, 2, 0, 0, 0, 0, 1)`. They can
 * also be passed in an array, as in
 * `applyMatrix([2, 0, 0, 0, 0, 2, 0, 0, 0, 0, 2, 0, 0, 0, 0, 1])`.
 *
 * By default, transformations accumulate. The
 * <a href="#/p5/push">push()</a> and <a href="#/p5/pop">pop()</a> functions
 * can be used to isolate transformations within distinct drawing groups.
 *
 * Note: Transformations are reset at the beginning of the draw loop. Calling
 * `applyMatrix()` inside the <a href="#/p5/draw">draw()</a> function won't
 * cause shapes to transform continuously.
 *
 * @method applyMatrix
 * @param  {Array} arr an array containing the elements of the transformation matrix. Its length should be either 6 (2D) or 16 (3D).

 * Rotates the coordinate system.

 * By default, the positive x-axis points to the right and the positive y-axis

 * rotating the coordinate system about the origin. Everything drawn after
 * `rotate()` is called will appear to be rotated.

 * The first parameter, `angle`, is the amount to rotate. For example, calling
 * `rotate(1)` rotates the coordinate system clockwise 1 radian which is
 * nearly 57˚. `rotate()` interprets angle values using the current
 * <a href="#/p5/angleMode">angleMode()</a>.
 *
 * The second parameter, `axis`, is optional. It's used to orient 3D rotations
 * in WebGL mode. If a <a href="#/p5.Vector">p5.Vector</a> is passed, as in
 * `rotate(QUARTER_PI, myVector)`, then the coordinate system will rotate
 * `QUARTER_PI` radians about `myVector`. If an array of vector components is
 * passed, as in `rotate(QUARTER_PI, [1, 0, 0])`, then the coordinate system
 * will rotate `QUARTER_PI` radians about a vector with the components
 * `[1, 0, 0]`.
 *
 * By default, transformations accumulate. For example, calling `rotate(1)`
 * twice has the same effect as calling `rotate(2)` once. The

 * Scales the coordinate system.
 *
 * By default, shapes are drawn at their original scale. A rectangle that's 50
 * pixels wide appears to take up half the width of a 100 pixel-wide canvas.
 * The `scale()` function can shrink or stretch the coordinate system so that
 * shapes appear at different sizes. There are two ways to call `scale()` with
 * parameters that set the scale factor(s).
 *
 * The first way to call `scale()` uses numbers to set the amount of scaling.
 * The first parameter, `s`, sets the amount to scale each axis. For example,
 * calling `scale(2)` stretches the x-, y-, and z-axes by a factor of 2. The
 * next two parameters, `y` and `z`, are optional. They set the amount to
 * scale the y- and z-axes. For example, calling `scale(2, 0.5, 1)` stretches
 * the x-axis by a factor of 2, shrinks the y-axis by a factor of 0.5, and
 * leaves the z-axis unchanged.
 *
 * The second way to call `scale()` uses a <a href="#/p5.Vector">p5.Vector</a>
 * object to set the scale factors. For example, calling `scale(myVector)`
 * uses the x-, y-, and z-components of `myVector` to set the amount of
 * scaling along the x-, y-, and z-axes. Doing so is the same as calling
 * `scale(myVector.x, myVector.y, myVector.z)`.
 *
 * By default, transformations accumulate. For example, calling `scale(1)`
 * twice has the same effect as calling `scale(2)` once. The
 * <a href="#/p5/push">push()</a> and <a href="#/p5/pop">pop()</a> functions
 * can be used to isolate transformations within distinct drawing groups.
 *
 * Note: Transformations are reset at the beginning of the draw loop. Calling
 * `scale(2)` inside the <a href="#/p5/draw">draw()</a> function won't cause
 * shapes to grow continuously.
 *
 * @method scale
 * @param  {Number|p5.Vector|Number[]} s amount to scale along the positive x-axis.

 * Creates a radio button element.
 *
 * The parameter is optional. If a string is passed, as in
 * `let myRadio = createSelect('food')`, then each radio option will
 * have `"food"` as its `name` parameter: `&lt;input name="food"&gt;&lt;/input&gt;`.
 * If an existing `&lt;div&gt;&lt;/div&gt;` or `&lt;span&gt;&lt;/span&gt;`
 * element is passed, as in `let myRadio = createSelect(container)`, it will
 * become the radio button's parent element.
 *
 * Radio buttons extend the <a href="#/p5.Element">p5.Element</a> class with a few
 * helpful methods for managing options:
 * - `myRadio.option(value, [label])` adds an option to the menu. The first paremeter, `value`, is a string that sets the option's value and label. The second parameter, `label`, is optional. If provided, it sets the label displayed for the `value`. If an option with `value` already exists, its label is changed and its value is returned.
 * - `myRadio.value()` returns the currently-selected option's value.
 * - `myRadio.selected()` returns the currently-selected option.
 * - `myRadio.selected(value)` selects the given option and returns it as an <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement" target="_blank">`HTMLInputElement`</a>.
 * - `myRadio.disable(shouldDisable)` enables the entire radio button if `true` is passed and disables it if `false` is passed.
 *
 * @method createRadio
 * @param  {Object} [containerElement] container HTML Element, either a `&lt;div&gt;&lt;/div&gt;`

 * Captures a sequence of frames from the canvas that can be saved as images.
 *
 * `saveFrames()` creates an array of frame objects. Each frame is stored as
 * an object with its file type, file name, and image data as a string. For
 * example, the first saved frame might have the following properties:
 *
 * `{ ext: 'png', filenmame: 'frame0', imageData: 'data:image/octet-stream;base64, abc123' }`.
 *
 * The first parameter, `filename`, sets the prefix for the file names. For
 * example, setting the prefix to `'frame'` would generate the image files
 * `frame0.png`, `frame1.png`, and so on.
 *
 * The second parameter, `extension`, sets the file type to either `'png'` or
 * `'jpg'`.
 *
 * The third parameter, `duration`, sets the duration to record in seconds.
 * The maximum duration is 15 seconds.
 *
 * The fourth parameter, `framerate`, sets the number of frames to record per
 * second. The maximum frame rate value is 22. Limits are placed on `duration`
 * and `framerate` to avoid using too much memory. Recording large canvases
 * can easily crash sketches or even web browsers.
 *
 * The fifth parameter, `callback`, is optional. If a function is passed,
 * image files won't be saved by default. The callback function can be used
 * to process an array containing the data for each captured frame. The array
 * of image data contains a sequence of objects with three properties for each
 * frame: `imageData`, `filename`, and `extension`.
 *
 * Note: Frames are downloaded as individual image files by default.
 *
 * @method saveFrames
 * @param  {String}   filename  prefix of file name.
 * @param  {String}   extension file extension, either 'jpg' or 'png'.
 * @param  {Number}   duration  duration in seconds to record. This parameter will be constrained to be less or equal to 15.
 * @param  {Number}   framerate number of frames to save per second. This parameter will be constrained to be less or equal to 22.
 * @param  {function(Array)} [callback] callback function that will be executed
                                  to handle the image data. This function
                                  should accept an array as argument. The
                                  array will contain the specified number of
                                  frames of objects. Each object has three
                                  properties: `imageData`, `filename`, and `extension`.
 * @example
 * <div>
 * <code>
 * function setup() {
 *   createCanvas(100, 100);
 *
 *   describe('A square repeatedly changes color from blue to pink.');
 * }
 *
 * function draw() {
 *   let r = frameCount % 255;
 *   let g = 50;
 *   let b = 100;
 *   background(r, g, b);
 * }
 *
 * // Save the frames when the user presses the 's' key.
 * function keyPressed() {
 *   if (key === 's') {
 *     saveFrames('frame', 'png', 1, 5);
 *   }
 * }

 * Loads an image to create a <a href="#/p5.Image">p5.Image</a> object.
 *
 * `loadImage()` interprets the first parameter one of three ways. If the path
 * to an image file is provided, `loadImage()` will load it. Paths to local
 * files should be relative, such as `'assets/thundercat.jpg'`. URLs such as
 * `'https://example.com/thundercat.jpg'` may be blocked due to browser
 * security. Raw image data can also be passed as a base64 encoded image in
 * the form `'data:image/png;base64,arandomsequenceofcharacters'`.
 *
 * The second parameter is optional. If a function is passed, it will be
 * called once the image has loaded. The callback function can optionally use
 * the new <a href="#/p5.Image">p5.Image</a> object.
 *
 * The third parameter is also optional. If a function is passed, it will be
 * called if the image fails to load. The callback function can optionally use
 * the event error.
 *
 * Images can take time to load. Calling `loadImage()` in
 * <a href="#/p5/preload">preload()</a> ensures images load before they're
 * used in <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.
 *
 * @method loadImage
 * @param  {String} path path of the image to be loaded or base64 encoded image.
 * @param  {function(p5.Image)} [successCallback] function called with
 *                               <a href="#/p5.Image">p5.Image</a> once it
 *                               loads.
 * @param  {function(Event)}    [failureCallback] function called with event
 *                               error if the image fails to load.
 * @return {p5.Image}            the <a href="#/p5.Image">p5.Image</a> object.
 *
 * @example
 * <div>
 * <code>
 * let img;

 * Generates a gif from a sketch and saves it to a file.

 *
 * The third parameter, `options`, is optional. If an object is passed,
 * `saveGif()` will use its properties to customize the gif. `saveGif()`
 * recognizes the properties `delay`, `units`, `silent`,
 * `notificationDuration`, and `notificationID`.
 *
 * @method saveGif
 * @param  {String} filename file name of gif.
 * @param  {Number} duration duration in seconds to capture from the sketch.
 * @param  {Object} [options] an object that can contain five more properties:
 *                  `delay`, a Number specifying how much time to wait before recording;
 *                  `units`, a String that can be either 'seconds' or 'frames'. By default it's 'seconds’;
 *                  `silent`, a Boolean that defines presence of progress notifications. By default it’s `false`;
 *                  `notificationDuration`, a Number that defines how long in seconds the final notification
 *                  will live. By default it's `0`, meaning the notification will never be removed;
 *                  `notificationID`, a String that specifies the id of the notification's DOM element. By default it’s `'progressBar’`.

 * Draws an image to the canvas.
 *
 * The first parameter, `img`, is the source image to be drawn. `img` can be

 * - <a href="#/p5.Image">p5.Image</a>
 * - <a href="#/p5.Element">p5.Element</a>
 * - <a href="#/p5.Texture">p5.Texture</a>
 * - <a href="#/p5.Framebuffer">p5.Framebuffer</a>
 * - <a href="#/p5.FramebufferTexture">p5.FramebufferTexture</a>
 *
 * The second and third parameters, `dx` and `dy`, set the coordinates of the
 * destination image's top left corner. See
 * <a href="#/p5/imageMode">imageMode()</a> for other ways to position images.
 *
 * Here's a diagram that explains how optional parameters work in `image()`:
 *
 * <img src="assets/drawImage.png"></img>
 *
 * The fourth and fifth parameters, `dw` and `dh`, are optional. They set the
 * the width and height to draw the destination image. By default, `image()`
 * draws the full source image at its original size.
 *
 * The sixth and seventh parameters, `sx` and `sy`, are also optional.
 * These coordinates define the top left corner of a subsection to draw from
 * the source image.
 *
 * The eighth and ninth parameters, `sw` and `sh`, are also optional.
 * They define the width and height of a subsection to draw from the source
 * image. By default, `image()` draws the full subsection that begins at
 * `(sx, sy)` and extends to the edges of the source image.
 *
 * The ninth parameter, `fit`, is also optional. It enables a subsection of
 * the source image to be drawn without affecting its aspect ratio. If
 * `CONTAIN` is passed, the full subsection will appear within the destination
 * rectangle. If `COVER` is passed, the subsection will completely cover the
 * destination rectangle. This may have the effect of zooming into the
 * subsection.
 *
 * The tenth and eleventh paremeters, `xAlign` and `yAlign`, are also
 * optional. They determine how to align the fitted subsection. `xAlign` can
 * be set to either `LEFT`, `RIGHT`, or `CENTER`. `yAlign` can be set to
 * either `TOP`, `BOTTOM`, or `CENTER`. By default, both `xAlign` and `yAlign`
 * are set to `CENTER`.
 *

 * @param  {p5.Image|p5.Element|p5.Texture|p5.Framebuffer|p5.FramebufferTexture} img image to display.

     *
     * `INVERT`
     * Inverts the colors in the image. No parameter is used.
     *
     * `GRAY`
     * Converts the image to grayscale. No parameter is used.
     *
     * `THRESHOLD`
     * Converts the image to black and white. Pixels with a grayscale value
     * above a given threshold are converted to white. The rest are converted to
     * black. The threshold must be between 0.0 (black) and 1.0 (white). If no
     * value is specified, 0.5 is used.
     *
     * `OPAQUE`
     * Sets the alpha channel to be entirely opaque. No parameter is used.
     *
     * `POSTERIZE`
     * Limits the number of colors in the image. Each color channel is limited to
     * the number of colors specified. Values between 2 and 255 are valid, but
     * results are most noticeable with lower values. The default value is 4.
     *
     * `BLUR`
     * Blurs the image. The level of blurring is specified by a blur radius. Larger
     * values increase the blur. The default value is 4. A gaussian blur is used
     * in `P2D` mode. A box blur is used in `WEBGL` mode.
     *
     * `ERODE`
     * Reduces the light areas. No parameter is used.
     *
     * `DILATE`
     * Increases the light areas. No parameter is used.

 * An array containing the color of each pixel on the canvas.
 *
 * Colors are stored as numbers representing red, green, blue, and alpha
 * (RGBA) values. `pixels` is a one-dimensional array for performance reasons.
 *
 * Each pixel occupies four elements in the `pixels` array, one for each RGBA
 * value. For example, the pixel at coordinates (0, 0) stores its RGBA values
 * at `pixels[0]`, `pixels[1]`, `pixels[2]`, and `pixels[3]`, respectively.
 * The next pixel at coordinates (1, 0) stores its RGBA values at `pixels[4]`,
 * `pixels[5]`, `pixels[6]`, and `pixels[7]`. And so on. The `pixels` array
 * for a 100&times;100 canvas has 100 &times; 100 &times; 4 = 40,000 elements.
 *
 * Some displays use several smaller pixels to set the color at a single
 * point. The <a href="#/p5/pixelDensity">pixelDensity()</a> function returns
 * the pixel density of the canvas. High density displays often have a
 * <a href="#/p5/pixelDensity">pixelDensity()</a> of 2. On such a display, the
 * `pixels` array for a 100&times;100 canvas has 200 &times; 200 &times; 4 =
 * 160,000 elements.
 *
 * Accessing the RGBA values for a point on the canvas requires a little math
 * as shown below. The <a href="#/p5/loadPixels">loadPixels()</a> function
 * must be called before accessing the `pixels` array. The
 * <a href="#/p5/updatePixels">updatePixels()</a> function must be called
 * after any changes are made.

 * Applies an image filter to the canvas.
 *
 * The preset options are:
 *
 * `INVERT`
 * Inverts the colors in the image. No parameter is used.
 *
 * `GRAY`
 * Converts the image to grayscale. No parameter is used.
 *
 * `THRESHOLD`
 * Converts the image to black and white. Pixels with a grayscale value
 * above a given threshold are converted to white. The rest are converted to
 * black. The threshold must be between 0.0 (black) and 1.0 (white). If no
 * value is specified, 0.5 is used.
 *
 * `OPAQUE`
 * Sets the alpha channel to entirely opaque. No parameter is used.
 *
 * `POSTERIZE`
 * Limits the number of colors in the image. Each color channel is limited to
 * the number of colors specified. Values between 2 and 255 are valid, but
 * results are most noticeable with lower values. The default value is 4.
 *
 * `BLUR`
 * Blurs the image. The level of blurring is specified by a blur radius. Larger
 * values increase the blur. The default value is 4. A gaussian blur is used
 * in `P2D` mode. A box blur is used in `WEBGL` mode.
 *
 * `ERODE`
 * Reduces the light areas. No parameter is used.
 *
 * `DILATE`
 * Increases the light areas. No parameter is used.
 *
 * `filter()` uses WebGL in the background by default because it's faster.
 * This can be disabled in `P2D` mode by adding a `false` argument, as in
 * `filter(BLUR, false)`. This may be useful to keep computation off the GPU
 * or to work around a lack of WebGL support.
 *
 * In WebgL mode, `filter()` can also use custom shaders. See
 * <a href="#/p5/createFilterShader">createFilterShader()</a> for more
 * information.

 * @param  {Number} [filterParam] parameter unique to each filter.
 * @param  {Boolean} [useWebGL]   flag to control whether to use fast
 *                                WebGL filters (GPU) or original image

 * Loads a JSON file to create an `Object`.
 *
 * JavaScript Object Notation
 * (<a href="https://developer.mozilla.org/en-US/docs/Glossary/JSON" target="_blank">JSON</a>)
 * is a standard format for sending data between applications. The format is
 * based on JavaScript objects which have keys and values. JSON files store
 * data in an object with strings as keys. Values can be strings, numbers,
 * Booleans, arrays, `null`, or other objects.
 *
 * The first parameter, `path`, is always a string with the path to the file.
 * Paths to local files should be relative, as in
 * `loadJSON('assets/data.json')`. URLs such as
 * `'https://example.com/data.json'` may be blocked due to browser security.
 *
 * The second parameter, `successCallback`, is optional. If a function is
 * passed, as in `loadJSON('assets/data.json', handleData)`, then the
 * `handleData()` function will be called once the data loads. The object
 * created from the JSON data will be passed to `handleData()` as its only argument.
 *
 * The third parameter, `failureCallback`, is also optional. If a function is
 * passed, as in `loadJSON('assets/data.json', handleData, handleFailure)`,
 * then the `handleFailure()` function will be called if an error occurs while
 * loading. The `Error` object will be passed to `handleFailure()` as its only
 * argument.
 *
 * Note: Data can take time to load. Calling `loadJSON()` within
 * <a href="#/p5/preload">preload()</a> ensures data loads before it's used in
 * <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.
 *
 * @method loadJSON
 * @param  {String} path path of the JSON file to be loaded.
 * @param  {function} [successCallback] function to call once the data is loaded. Will be passed the object.
 * @param  {function} [errorCallback] function to call if the data fails to load. Will be passed an `Error` event object.
 * @return {Object} object containing the loaded data.
 *
 * @example
 *
 * <div>
 * <code>
 * let myData;
 *
 * // Load the JSON and create an object.
 * function preload() {
 *   myData = loadJSON('assets/data.json');

 * Loads a text file to create an `Array`.

 * The first parameter, `path`, is always a string with the path to the file.
 * Paths to local files should be relative, as in
 * `loadStrings('assets/data.txt')`. URLs such as
 * `'https://example.com/data.txt'` may be blocked due to browser security.
 *
 * The second parameter, `successCallback`, is optional. If a function is
 * passed, as in `loadStrings('assets/data.txt', handleData)`, then the
 * `handleData()` function will be called once the data loads. The array
 * created from the text data will be passed to `handleData()` as its only
 * argument.
 *
 * The third parameter, `failureCallback`, is also optional. If a function is
 * passed, as in `loadStrings('assets/data.txt', handleData, handleFailure)`,
 * then the `handleFailure()` function will be called if an error occurs while
 * loading. The `Error` object will be passed to `handleFailure()` as its only
 * argument.
 *
 * Note: Data can take time to load. Calling `loadStrings()` within
 * <a href="#/p5/preload">preload()</a> ensures data loads before it's used in
 * <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.

 * @param  {function} [errorCallback] function to call if the data fails to
 *                                    load. Will be passed an `Error` event

 * Loads an XML file to create a <a href="#/p5.XML">p5.XML</a> object.
 *
 * Extensible Markup Language
 * (<a href="https://developer.mozilla.org/en-US/docs/Web/XML/XML_introduction" target="_blank">XML</a>)
 * is a standard format for sending data between applications. Like HTML, the
 * XML format is based on tags and attributes, as in
 * `&lt;time units="s"&gt;1234&lt;/time&gt;`.
 *
 * The first parameter, `path`, is always a string with the path to the file.
 * Paths to local files should be relative, as in
 * `loadXML('assets/data.xml')`. URLs such as `'https://example.com/data.xml'`
 * may be blocked due to browser security.
 *
 * The second parameter, `successCallback`, is optional. If a function is
 * passed, as in `loadXML('assets/data.xml', handleData)`, then the
 * `handleData()` function will be called once the data loads. The
 * <a href="#/p5.XML">p5.XML</a> object created from the data will be passed
 * to `handleData()` as its only argument.
 *
 * The third parameter, `failureCallback`, is also optional. If a function is
 * passed, as in `loadXML('assets/data.xml', handleData, handleFailure)`, then
 * the `handleFailure()` function will be called if an error occurs while
 * loading. The `Error` object will be passed to `handleFailure()` as its only
 * argument.
 *
 * Note: Data can take time to load. Calling `loadXML()` within
 * <a href="#/p5/preload">preload()</a> ensures data loads before it's used in
 * <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.
 *
 * @method loadXML
 * @param  {String} path path of the XML file to be loaded.
 * @param  {function} [successCallback] function to call once the data is
 *                                      loaded. Will be passed the
 *                                      <a href="#/p5.XML">p5.XML</a> object.
 * @param  {function} [errorCallback] function to call if the data fails to
 *                                    load. Will be passed an `Error` event
 *                                    object.

 * Saves an `Object` or `Array` to a JSON file.
 *
 * JavaScript Object Notation
 * (<a href="https://developer.mozilla.org/en-US/docs/Glossary/JSON" target="_blank">JSON</a>)
 * is a standard format for sending data between applications. The format is
 * based on JavaScript objects which have keys and values. JSON files store
 * data in an object with strings as keys. Values can be strings, numbers,
 * Booleans, arrays, `null`, or other objects.
 *
 * The first parameter, `json`, is the data to save. The data can be an array,
 * as in `[1, 2, 3]`, or an object, as in
 * `{ x: 50, y: 50, color: 'deeppink' }`.
 *
 * The second parameter, `filename`, is a string that sets the file's name.
 * For example, calling `saveJSON([1, 2, 3], 'data.json')` saves the array
 * `[1, 2, 3]` to a file called `data.json` on the user's computer.
 *
 * The third parameter, `optimize`, is optional. If `true` is passed, as in
 * `saveJSON([1, 2, 3], 'data.json', true)`, then all unneeded whitespace will
 * be removed to reduce the file size.
 *
 * Note: The browser will either save the file immediately or prompt the user
 * with a dialogue window.
 *
 * @method saveJSON
 * @param  {Array|Object} json data to save.
 * @param  {String} filename name of the file to be saved.
 * @param  {Boolean} [optimize] whether to trim unneeded whitespace. Defaults

 * Creates a new <a href="#/p5.Vector">p5.Vector</a> object.
 *
 * A vector can be thought of in different ways. In one view, a vector is like
 * an arrow pointing in space. Vectors have both magnitude (length) and
 * direction. This view is helpful for programming motion.
 *
 * A vector's components determine its magnitude and direction. For example,
 * calling `createVector(3, 4)` creates a new
 * <a href="#/p5.Vector">p5.Vector</a> object with an x-component of 3 and a
 * y-component of 4. From the origin, this vector's tip is 3 units to the
 * right and 4 units down.
 *
 * <a href="#/p5.Vector">p5.Vector</a> objects are often used to program
 * motion because they simplify the math. For example, a moving ball has a
 * position and a velocity. Position describes where the ball is in space. The
 * ball's position vector extends from the origin to the ball's center.
 * Velocity describes the ball's speed and the direction it's moving. If the
 * ball is moving straight up, its velocity vector points straight up. Adding
 * the ball's velocity vector to its position vector moves it, as in
 * `pos.add(vel)`. Vector math relies on methods inside the
 * <a href="#/p5.Vector">p5.Vector</a> class.
 *
 * @method createVector
 * @param {Number} [x] x component of the vector.
 * @param {Number} [y] y component of the vector.
 * @param {Number} [z] z component of the vector.
 * @return {p5.Vector} new <a href="#/p5.Vector">p5.Vector</a> object.

 * Returns random numbers that can be tuned to feel organic.
 *
 * Values returned by <a href="#/p5/random">random()</a> and
 * <a href="#/p5/randomGaussian">randomGaussian()</a> can change by large
 * amounts between function calls. By contrast, values returned by `noise()`
 * can be made "smooth". Calls to `noise()` with similar inputs will produce
 * similar outputs. `noise()` is used to create textures, motion, shapes,
 * terrains, and so on. Ken Perlin invented `noise()` while animating the
 * original <em>Tron</em> film in the 1980s.
 *
 * `noise()` always returns values between 0 and 1. It returns the same value
 * for a given input while a sketch is running. `noise()` produces different
 * results each time a sketch runs. The
 * <a href="#/p5/noiseSeed">noiseSeed()</a> function can be used to generate
 * the same sequence of Perlin noise values each time a sketch runs.
 *
 * The character of the noise can be adjusted in two ways. The first way is to
 * scale the inputs. `noise()` interprets inputs as coordinates. The sequence
 * of noise values will be smoother when the input coordinates are closer. The
 * second way is to use the <a href="#/p5/noiseDetail">noiseDetail()</a>
 * function.
 *
 * The version of `noise()` with one parameter computes noise values in one
 * dimension. This dimension can be thought of as space, as in `noise(x)`, or
 * time, as in `noise(t)`.
 *
 * The version of `noise()` with two parameters computes noise values in two
 * dimensions. These dimensions can be thought of as space, as in
 * `noise(x, y)`, or space and time, as in `noise(x, t)`.
 *
 * The version of `noise()` with three parameters computes noise values in
 * three dimensions. These dimensions can be thought of as space, as in
 * `noise(x, y, z)`, or space and time, as in `noise(x, y, t)`.

 * A class to describe a two or three-dimensional vector.
 *
 * A vector can be thought of in different ways. In one view, a vector is like
 * an arrow pointing in space. Vectors have both magnitude (length) and
 * direction.
 *
 * `p5.Vector` objects are often used to program motion because they simplify
 * the math. For example, a moving ball has a position and a velocity.
 * Position describes where the ball is in space. The ball's position vector
 * extends from the origin to the ball's center. Velocity describes the ball's
 * speed and the direction it's moving. If the ball is moving straight up, its
 * velocity vector points straight up. Adding the ball's velocity vector to
 * its position vector moves it, as in `pos.add(vel)`. Vector math relies on
 * methods inside the `p5.Vector` class.
 *
 * Note: <a href="#/p5/createVector">createVector()</a> is the recommended way
 * to make an instance of this class.

 * @class p5.Vector
 * @constructor

 * <a href="#/p5/sin">sin()</a> expect angles measured radians by default.
 * Calling `angleMode(DEGREES)` switches to degrees. Calling
 * `angleMode(RADIANS)` switches back to radians.
 *
 * Calling `angleMode()` with no arguments returns current angle mode, which
 * is either `RADIANS` or `DEGREES`.
 *
 * @method angleMode
 * @param {Constant} mode either RADIANS or DEGREES.

    * Returns an array of points outlining a string of text written using the
    * font.
    *
    * Each point object in the array has three properties that describe the
    * point's location and orientation, called its path angle. For example,
    * `{ x: 10, y: 20, alpha: 450 }`.
    *
    * The first parameter, `str`, is a string of text. The second and third
    * parameters, `x` and `y`, are the text's position. By default, they set the
    * coordinates of the bounding box's bottom-left corner. See
    * <a href="#/p5/textAlign">textAlign()</a> for more ways to align text.
    *
    * The fourth parameter, `fontSize`, is optional. It sets the text's font
    * size. By default, `font.textToPoints()` will use the current
    * <a href="#/p5/textSize">textSize()</a>.
    *
    * The fifth parameter, `options`, is also optional. `font.textToPoints()`
    * expects an object with the following properties:
    *
    * `sampleFactor` is the ratio of the text's path length to the number of
    * samples. It defaults to 0.1. Higher values produce more points along the
    * path and are more precise.
    *
    * `simplifyThreshold` removes collinear points if it's set to a number other
    * than 0. The value represents the threshold angle to use when determining
    * whether two edges are collinear.
    *
    * @method textToPoints
    * @param  {String} str        string of text.
    * @param  {Number} x          x-coordinate of the text.
    * @param  {Number} y          y-coordinate of the text.
    * @param  {Number} [fontSize] font size. Defaults to the current
    *                             <a href="#/p5/textSize">textSize()</a>.
    * @param  {Object} [options]  object with sampleFactor and simplifyThreshold
    *                             properties.
    * @return {Array} array of point objects, each with x, y, and alpha (path angle) properties.
    *

 * from a list are detected.
 *

 *
 * The second parameter, `delim`, is optional. It sets the character(s) that
 * should be used to split the string. `delim` can be a single string, as in
 * `splitTokens('rock...paper...scissors...shoot', '...')`, or an array of
 * strings, as in
 * `splitTokens('rock;paper,scissors...shoot, [';', ',', '...'])`. By default,
 * if no `delim` characters are specified, then any whitespace character is
 * used to split. Whitespace characters include tab (`\t`), line feed (`\n`),
 * carriage return (`\r`), form feed (`\f`), and space.

 *
 * Note: A <a href="#/p5.Geometry">p5.Geometry</a> object can still be drawn
 * after its resources are cleared from GPU memory. It may take longer to draw

 * Draws a sphere.
 *
 * A sphere is a 3D shape with triangular faces that connect to form a round
 * surface. Spheres with few faces look like crystals. Spheres with many faces
 * have smooth surfaces and look like balls.
 *
 * The first parameter, `radius`, is optional. If a `Number` is passed, as in
 * `sphere(20)`, it sets the radius of the sphere. By default, `radius` is 50.
 *
 * The second parameter, `detailX`, is also optional. If a `Number` is passed,
 * as in `sphere(20, 5)`, it sets the number of triangle subdivisions to use
 * along the x-axis. All 3D shapes are made by connecting triangles to form
 * their surfaces. By default, `detailX` is 24.
 *
 * The third parameter, `detailY`, is also optional. If a `Number` is passed,
 * as in `sphere(20, 5, 2)`, it sets the number of triangle subdivisions to
 * use along the y-axis. All 3D shapes are made by connecting triangles to
 * form their surfaces. By default, `detailY` is 16.
 *
 * Note: `sphere()` can only be used in WebGL mode.
 *
 * @method sphere
 * @param  {Number} [radius]   radius of the sphere. Defaults to 50.
 * @param  {Integer} [detailX] number of triangle subdivisions along the x-axis. Defaults to 24.

 * Draws an ellipsoid.
 *
 * An ellipsoid is a 3D shape with triangular faces that connect to form a
 * round surface. Ellipsoids with few faces look like crystals. Ellipsoids
 * with many faces have smooth surfaces and look like eggs. `ellipsoid()`
 * defines a shape by its radii. This is different from
 * <a href="#/p5/ellipse">ellipse()</a> which uses diameters
 * (width and height).
 *
 * The first parameter, `radiusX`, is optional. If a `Number` is passed, as in
 * `ellipsoid(20)`, it sets the radius of the ellipsoid along the x-axis. By
 * default, `radiusX` is 50.
 *
 * The second parameter, `radiusY`, is also optional. If a `Number` is passed,
 * as in `ellipsoid(20, 30)`, it sets the ellipsoid’s radius along the y-axis.
 * By default, `radiusY` is set to the ellipsoid’s `radiusX`.
 *
 * The third parameter, `radiusZ`, is also optional. If a `Number` is passed,
 * as in `ellipsoid(20, 30, 40)`, it sets the ellipsoid’s radius along the
 * z-axis. By default, `radiusZ` is set to the ellipsoid’s `radiusY`.
 *
 * The fourth parameter, `detailX`, is also optional. If a `Number` is passed,
 * as in `ellipsoid(20, 30, 40, 5)`, it sets the number of triangle
 * subdivisions to use along the x-axis. All 3D shapes are made by connecting
 * triangles to form their surfaces. By default, `detailX` is 24.
 *
 * The fifth parameter, `detailY`, is also optional. If a `Number` is passed,
 * as in `ellipsoid(20, 30, 40, 5, 7)`, it sets the number of triangle
 * subdivisions to use along the y-axis. All 3D shapes are made by connecting
 * triangles to form their surfaces. By default, `detailY` is 16.
 *
 * Note: `ellipsoid()` can only be used in WebGL mode.
 *
 * @method ellipsoid
 * @param  {Number} [radiusX]  radius of the ellipsoid along the x-axis. Defaults to 50.
 * @param  {Number} [radiusY]  radius of the ellipsoid along the y-axis. Defaults to `radiusX`.

        /**
 * Allows the user to orbit around a 3D sketch using a mouse, trackpad, or
 * touchscreen.
 *
 * 3D sketches are viewed through an imaginary camera. Calling
 * `orbitControl()` within the <a href="#/p5/draw">draw()</a> function allows
 * the user to change the camera’s position:
 *
 * ```js
 * function draw() {
 *   background(200);
 *
 *   // Enable orbiting with the mouse.
 *   orbitControl();
 *
 *   // Rest of sketch.
 * }
 * ```
 *
 * Left-clicking and dragging or swipe motion will rotate the camera position
 * about the center of the sketch. Right-clicking and dragging or multi-swipe
 * will pan the camera position without rotation. Using the mouse wheel
 * (scrolling) or pinch in/out will move the camera further or closer from the
 * center of the sketch.
 *
 * The first three parameters, `sensitivityX`, `sensitivityY`, and
 * `sensitivityZ`, are optional. They’re numbers that set the sketch’s
 * sensitivity to movement along each axis. For example, calling
 * `orbitControl(1, 2, -1)` keeps movement along the x-axis at its default
 * value, makes the sketch twice as sensitive to movement along the y-axis,
 * and reverses motion along the z-axis. By default, all sensitivity values
 * are 1.
 *
 * The fourth parameter, `options`, is also optional. It’s an object that
 * changes the behavior of orbiting. For example, calling
 * `orbitControl(1, 1, 1, options)` keeps the default sensitivity values while
 * changing the behaviors set with `options`. The object can have the
 * following properties:
 *
 * ```js
 * let options = {
 *   // Setting this to false makes mobile interactions smoother by
 *   // preventing accidental interactions with the page while orbiting.
 *   // By default, it's true.
 *   disableTouchActions: true,
 *
 *   // Setting this to true makes the camera always rotate in the
 *   // direction the mouse/touch is moving.
 *   // By default, it's false.
 *   freeRotation: false
 * };
 *
 * orbitControl(1, 1, 1, options);
 * ```
 *
 * @method orbitControl
 * @for p5
 * @param  {Number} [sensitivityX] sensitivity to movement along the x-axis. Defaults to 1.
 * @param  {Number} [sensitivityY] sensitivity to movement along the y-axis. Defaults to 1.
 * @param  {Number} [sensitivityZ] sensitivity to movement along the z-axis. Defaults to 1.
 * @param  {Object} [options] object with two optional properties, `disableTouchActions`
 *                            and `freeRotation`. Both are `Boolean`s. `disableTouchActions`
 *                            defaults to `true` and `freeRotation` defaults to `false`.

        /**
 * Adds a grid and an axes icon to clarify orientation in 3D sketches.
 *
 * `debugMode()` adds a grid that shows where the “ground” is in a sketch. By
 * default, the grid will run through the origin `(0, 0, 0)` of the sketch
 * along the XZ plane. `debugMode()` also adds an axes icon that points along
 * the positive x-, y-, and z-axes. Calling `debugMode()` displays the grid
 * and axes icon with their default size and position.
 *
 * There are four ways to call `debugMode()` with optional parameters to
 * customize the debugging environment.
 *
 * The first way to call `debugMode()` has one parameter, `mode`. If the
 * system constant `GRID` is passed, as in `debugMode(GRID)`, then the grid
 * will be displayed and the axes icon will be hidden. If the constant `AXES`
 * is passed, as in `debugMode(AXES)`, then the axes icon will be displayed
 * and the grid will be hidden.
 *
 * The second way to call `debugMode()` has six parameters. The first
 * parameter, `mode`, selects either `GRID` or `AXES` to be displayed. The
 * next five parameters, `gridSize`, `gridDivisions`, `xOff`, `yOff`, and
 * `zOff` are optional. They’re numbers that set the appearance of the grid
 * (`gridSize` and `gridDivisions`) and the placement of the axes icon
 * (`xOff`, `yOff`, and `zOff`). For example, calling
 * `debugMode(20, 5, 10, 10, 10)` sets the `gridSize` to 20 pixels, the number
 * of `gridDivisions` to 5, and offsets the axes icon by 10 pixels along the
 * x-, y-, and z-axes.
 *
 * The third way to call `debugMode()` has five parameters. The first
 * parameter, `mode`, selects either `GRID` or `AXES` to be displayed. The
 * next four parameters, `axesSize`, `xOff`, `yOff`, and `zOff` are optional.
 * They’re numbers that set the appearance of the size of the axes icon
 * (`axesSize`) and its placement (`xOff`, `yOff`, and `zOff`).
 *
 * The fourth way to call `debugMode()` has nine optional parameters. The
 * first five parameters, `gridSize`, `gridDivisions`, `gridXOff`, `gridYOff`,
 * and `gridZOff` are numbers that set the appearance of the grid. For
 * example, calling `debugMode(100, 5, 0, 0, 0)` sets the `gridSize` to 100,
 * the number of `gridDivisions` to 5, and sets all the offsets to 0 so that
 * the grid is centered at the origin. The next four parameters, `axesSize`,
 * `xOff`, `yOff`, and `zOff` are numbers that set the appearance of the size
 * of the axes icon (`axesSize`) and its placement (`axesXOff`, `axesYOff`,
 * and `axesZOff`). For example, calling
 * `debugMode(100, 5, 0, 0, 0, 50, 10, 10, 10)` sets the `gridSize` to 100,
 * the number of `gridDivisions` to 5, and sets all the offsets to 0 so that
 * the grid is centered at the origin. It then sets the `axesSize` to 50 and
 * offsets the icon 10 pixels along each axis.

 * <a href="#/p5/directionalLight">directionalLight()</a>,
 * <a href="#/p5/pointLight">pointLight()</a>, and
 * <a href="#/p5/spotLight">spotLight()</a>. The function helps to create
 * highlights on <a href="#/p5.Geometry">p5.Geometry</a> objects that are
 * styled with <a href="#/p5/specularMaterial">specularMaterial()</a>. If a
 * geometry does not use
 * <a href="#/p5/specularMaterial">specularMaterial()</a>, then
 * `specularColor()` will have no effect.
 *
 * Note: `specularColor()` doesn’t affect lights that bounce in all
 * directions, including <a href="#/p5/ambientLight">ambientLight()</a> and
 * <a href="#/p5/imageLight">imageLight()</a>.
 *
 * There are three ways to call `specularColor()` with optional parameters to
 * set the specular highlight color.
 *
 * The first way to call `specularColor()` has two optional parameters, `gray`
 * and `alpha`. Grayscale and alpha values between 0 and 255, as in
 * `specularColor(50)` or `specularColor(50, 80)`, can be passed to set the
 * specular highlight color.
 *
 * The second way to call `specularColor()` has one optional parameter,
 * `color`. A <a href="#/p5.Color">p5.Color</a> object, an array of color
 * values, or a CSS color string can be passed to set the specular highlight
 * color.
 *
 * The third way to call `specularColor()` has four optional parameters, `v1`,
 * `v2`, `v3`, and `alpha`. RGBA, HSBA, or HSLA values, as in
 * `specularColor(255, 0, 0, 80)`, can be passed to set the specular highlight
 * color. Color values will be interpreted using the current
 * <a href="#/p5/colorMode">colorMode()</a>.
 *
 * @method specularColor
 * @param  {Number}        v1 red or hue value in the current

 * Creates a light that shines from a point in one direction.
 *
 * Spot lights are like flashlights that shine in one direction creating a
 * cone of light. The shape of the cone can be controlled using the angle and
 * concentration parameters. A maximum of 5 spot lights can be active at once.
 *
 * There are eight ways to call `spotLight()` with parameters to set the
 * light’s color, position, direction. For example,
 * `spotLight(255, 0, 0, 0, 0, 0, 1, 0, 0)` creates a red `(255, 0, 0)` light
 * at the origin `(0, 0, 0)` that points to the right `(1, 0, 0)`.
 *
 * The `angle` parameter is optional. It sets the radius of the light cone.
 * For example, `spotLight(255, 0, 0, 0, 0, 0, 1, 0, 0, PI / 16)` creates a
 * red `(255, 0, 0)` light at the origin `(0, 0, 0)` that points to the right
 * `(1, 0, 0)` with an angle of `PI / 16` radians. By default, `angle` is
 * `PI / 3` radians.
 *
 * The `concentration` parameter is also optional. It focuses the light
 * towards the center of the light cone. For example,
 * `spotLight(255, 0, 0, 0, 0, 0, 1, 0, 0, PI / 16, 50)` creates a red
 * `(255, 0, 0)` light at the origin `(0, 0, 0)` that points to the right
 * `(1, 0, 0)` with an angle of `PI / 16` radians at concentration of 50. By
 * default, `concentration` is 100.

        /**
 * Loads a 3D model to create a
 * <a href="#/p5.Geometry">p5.Geometry</a> object.
 *
 * `loadModel()` can load 3D models from OBJ and STL files. Once the model is
 * loaded, it can be displayed with the
 * <a href="#/p5/model">model()</a> function, as in `model(shape)`.
 *
 * There are three ways to call `loadModel()` with optional parameters to help
 * process the model.
 *
 * The first parameter, `path`, is always a `String` with the path to the
 * file. Paths to local files should be relative, as in
 * `loadModel('assets/model.obj')`. URLs such as
 * `'https://example.com/model.obj'` may be blocked due to browser security.
 *
 * The first way to call `loadModel()` has three optional parameters after the
 * file path. The first optional parameter, `successCallback`, is a function
 * to call once the model loads. For example,
 * `loadModel('assets/model.obj', handleModel)` will call the `handleModel()`
 * function once the model loads. The second optional parameter,
 * `failureCallback`, is a function to call if the model fails to load. For
 * example, `loadModel('assets/model.obj', handleModel, handleFailure)` will
 * call the `handleFailure()` function if an error occurs while loading. The
 * third optional parameter, `fileType`, is the model’s file extension as a
 * string. For example,
 * `loadModel('assets/model', handleModel, handleFailure, '.obj')` will try to
 * load the file model as a `.obj` file.
 *
 * The second way to call `loadModel()` has four optional parameters after the
 * file path. The first optional parameter is a `Boolean` value. If `true` is
 * passed, as in `loadModel('assets/model.obj', true)`, then the model will be
 * resized to ensure it fits the canvas. The next three parameters are
 * `successCallback`, `failureCallback`, and `fileType` as described above.
 *
 * The third way to call `loadModel()` has one optional parameter after the
 * file path. The optional parameter, `options`, is an `Object` with options,
 * as in `loadModel('assets/model.obj', options)`. The `options` object can
 * have the following properties:
 *
 * ```js
 * let options = {
 *   // Enables standardized size scaling during loading if set to true.
 *   normalize: true,
 *
 *   // Function to call once the model loads.
 *   successCallback: handleModel,
 *
 *   // Function to call if an error occurs while loading.
 *   failureCallback: handleError,
 *
 *   // Model's file extension.
 *   fileType: '.stl',
 *
 *   // Flips the U texture coordinates of the model.
 *   flipU: false,
 *
 *   // Flips the V texture coordinates of the model.
 *   flipV: false
 * };
 *
 * // Pass the options object to loadModel().
 * loadModel('assets/model.obj', options);
 * ```
 *
 * Models can take time to load. Calling `loadModel()` in
 * <a href="#/p5/preload">preload()</a> ensures models load before they're
 * used in <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.
 *
 * Note: There’s no support for colored STL files. STL files with color will
 * be rendered without color.
 *
 * @method loadModel
 * @param  {String} path              path of the model to be loaded.
 * @param  {Boolean} normalize        if `true`, scale the model to fit the canvas.
 * @param  {function(p5.Geometry)} [successCallback] function to call once the model is loaded. Will be passed
 *                                                   the <a href="#/p5.Geometry">p5.Geometry</a> object.
 * @param  {function(Event)} [failureCallback] function to call if the model fails to load. Will be passed an `Error` event object.
 * @param  {String} [fileType]          model’s file extension. Either `'.obj'` or `'.stl'`.
 * @return {p5.Geometry} the <a href="#/p5.Geometry">p5.Geometry</a> object

 * Loads vertex and fragment shaders to create a
 * <a href="#/p5.Shader">p5.Shader</a> object.
 *
 * Shaders are programs that run on the graphics processing unit (GPU). They
 * can process many pixels at the same time, making them fast for many
 * graphics tasks. They’re written in a language called
 * <a href="https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders" target="_blank">GLSL</a>
 * and run along with the rest of the code in a sketch.
 *
 * Once the <a href="#/p5.Shader">p5.Shader</a> object is created, it can be
 * used with the <a href="#/p5/shader">shader()</a> function, as in
 * `shader(myShader)`. A shader program consists of two files, a vertex shader
 * and a fragment shader. The vertex shader affects where 3D geometry is drawn
 * on the screen and the fragment shader affects color.
 *
 * `loadShader()` loads the vertex and fragment shaders from their `.vert` and
 * `.frag` files. For example, calling
 * `loadShader('assets/shader.vert', 'assets/shader.frag')` loads both
 * required shaders and returns a <a href="#/p5.Shader">p5.Shader</a> object.
 *
 * The third parameter, `successCallback`, is optional. If a function is
 * passed, it will be called once the shader has loaded. The callback function
 * can use the new <a href="#/p5.Shader">p5.Shader</a> object as its
 * parameter.
 *
 * The fourth parameter, `failureCallback`, is also optional. If a function is
 * passed, it will be called if the shader fails to load. The callback
 * function can use the event error as its parameter.
 *
 * Shaders can take time to load. Calling `loadShader()` in
 * <a href="#/p5/preload">preload()</a> ensures shaders load before they're
 * used in <a href="#/p5/setup">setup()</a> or <a href="#/p5/draw">draw()</a>.
 *
 * Note: Shaders can only be used in WebGL mode.
 *
 * @method loadShader
 * @param {String} vertFilename path of the vertex shader to be loaded.

 * Once the <a href="#/p5.Shader">p5.Shader</a> object is created, it can be
 * used with the <a href="#/p5/shader">shader()</a> function, as in
 * `shader(myShader)`. A shader program consists of two parts, a vertex shader
 * and a fragment shader. The vertex shader affects where 3D geometry is drawn
 * on the screen and the fragment shader affects color.
 *
 * The first parameter, `vertSrc`, sets the vertex shader. It’s a string that
 * contains the vertex shader program written in GLSL.
 *
 * The second parameter, `fragSrc`, sets the fragment shader. It’s a string
 * that contains the fragment shader program written in GLSL.
 *
 * A shader can optionally describe *hooks,* which are functions in GLSL that
 * users may choose to provide to customize the behavior of the shader using the
 * <a href="#/p5.Shader/modify">`modify()`</a> method of `p5.Shader`. These are added by
 * describing the hooks in a third parameter, `options`, and referencing the hooks in
 * your `vertSrc` or `fragSrc`. Hooks for the vertex or fragment shader are described under
 * the `vertex` and `fragment` keys of `options`. Each one is an object. where each key is
 * the type and name of a hook function, and each value is a string with the
 * parameter list and default implementation of the hook. For example, to let users
 * optionally run code at the start of the vertex shader, the options object could
 * include:
 *
 * ```js
 * {
 *   vertex: {
 *     'void beforeVertex': '() {}'
 *   }
 * }
 * ```
 *
 * Then, in your vertex shader source, you can run a hook by calling a function
 * with the same name prefixed by `HOOK_`. If you want to check if the default
 * hook has been replaced, maybe to avoid extra overhead, you can check if the
 * same name prefixed by `AUGMENTED_HOOK_` has been defined:
 *
 * ```glsl
 * void main() {
 *   // In most cases, just calling the hook is fine:
 *   HOOK_beforeVertex();
 *
 *   // Alternatively, for more efficiency:
 *   #ifdef AUGMENTED_HOOK_beforeVertex
 *   HOOK_beforeVertex();
 *   #endif
 *
 *   // Add the rest of your shader code here!
 * }
 * ```
 *
 * Note: Only filter shaders can be used in 2D mode. All shaders can be used
 * in WebGL mode.
 *
 * @method createShader
 * @param {String} vertSrc source code for the vertex shader.
 * @param {String} fragSrc source code for the fragment shader.
 * @param {Object} [options] An optional object describing how this shader can
 * be augmented with hooks. It can include:
 *  - `vertex`: An object describing the available vertex shader hooks.

 * shader included. `createFilterShader()` is intended to be used along with
 * <a href="#/p5/filter">filter()</a> for filtering the contents of a canvas.
 * A filter shader will be applied to the whole canvas instead of just
 * <a href="#/p5.Geometry">p5.Geometry</a> objects.
 *
 * The parameter, `fragSrc`, sets the fragment shader. It’s a string that
 * contains the fragment shader program written in
 * <a href="https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders" target="_blank">GLSL</a>.
 *
 * The <a href="#/p5.Shader">p5.Shader</a> object that's created has some
 * uniforms that can be set:
 * - `sampler2D tex0`, which contains the canvas contents as a texture.
 * - `vec2 canvasSize`, which is the width and height of the canvas, not including pixel density.
 * - `vec2 texelSize`, which is the size of a physical pixel including pixel density. This is calculated as `1.0 / (width * density)` for the pixel width and `1.0 / (height * density)` for the pixel height.
 *
 * The <a href="#/p5.Shader">p5.Shader</a> that's created also provides
 * `varying vec2 vTexCoord`, a coordinate with values between 0 and 1.
 * `vTexCoord` describes where on the canvas the pixel will be drawn.

 * <a href="https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders" target="_blank">GLSL</a>

 * <a href="#/p5/createShader">createShader()</a> and
 * <a href="#/p5/loadShader">loadShader()</a> functions.
 *
 * The parameter, `s`, is the <a href="#/p5.Shader">p5.Shader</a> object to
 * apply. For example, calling `shader(myShader)` applies `myShader` to
 * process each pixel on the canvas. The shader will be used for:
 * - Fills when a texture is enabled if it includes a uniform `sampler2D`.
 * - Fills when lights are enabled if it includes the attribute `aNormal`, or if it has any of the following uniforms: `uUseLighting`, `uAmbientLightCount`, `uDirectionalLightCount`, `uPointLightCount`, `uAmbientColor`, `uDirectionalDiffuseColors`, `uDirectionalSpecularColors`, `uPointLightLocation`, `uPointLightDiffuseColors`, `uPointLightSpecularColors`, `uLightingDirection`, or `uSpecular`.
 * - Fills whenever there are no lights or textures.
 * - Strokes if it includes the uniform `uStrokeWeight`.
 *
 * The source code from a <a href="#/p5.Shader">p5.Shader</a> object's
 * fragment and vertex shaders will be compiled the first time it's passed to
 * `shader()`. See

 *
 * <code>
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * rect(0, 0, 30, 50);
 * </code>
 *
 * If the image in the code snippet above has dimensions of 300 x 500 pixels,
 * the same result could be achieved as follows:
 *
 * <code>
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * beginShape();
 *
 * // Top-left.
 * // u: 0, v: 0
 * vertex(0, 0, 0, 0, 0);
 *
 * // Top-right.
 * // u: 300, v: 0
 * vertex(30, 0, 0, 300, 0);
 *
 * // Bottom-right.
 * // u: 300, v: 500
 * vertex(30, 50, 0, 300, 500);
 *
 * // Bottom-left.
 * // u: 0, v: 500
 * vertex(0, 50, 0, 0, 500);
 *
 * endShape();
 * </code>
 *
 * `textureMode()` changes the coordinate system for uv coordinates.
 *
 * The parameter, `mode`, accepts two possible constants. If `NORMAL` is
 * passed, as in `textureMode(NORMAL)`, then the texture’s uv coordinates can
 * be provided in the range 0 to 1 instead of the image’s dimensions. This can
 * be helpful for using the same code for multiple images of different sizes.
 * For example, the code snippet above could be rewritten as follows:
 *
 * <code>
 * // Set the texture mode to use normalized coordinates.
 * textureMode(NORMAL);
 *
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * beginShape();
 *
 * // Top-left.
 * // u: 0, v: 0
 * vertex(0, 0, 0, 0, 0);
 *
 * // Top-right.
 * // u: 1, v: 0
 * vertex(30, 0, 0, 1, 0);
 *
 * // Bottom-right.
 * // u: 1, v: 1
 * vertex(30, 50, 0, 1, 1);
 *
 * // Bottom-left.
 * // u: 0, v: 1
 * vertex(0, 50, 0, 0, 1);
 *
 * endShape();
 * </code>
 *
 * By default, `mode` is `IMAGE`, which scales uv coordinates to the
 * dimensions of the image. Calling `textureMode(IMAGE)` applies the default.
 *
 * Note: `textureMode()` can only be used in WebGL mode.
 *
 * @method  textureMode
 * @param {Constant} mode either IMAGE or NORMAL.

        /**
 * Changes the way textures behave when a shape’s uv coordinates go beyond the
 * texture.
 *
 * In order for <a href="#/p5/texture">texture()</a> to work, a shape needs a
 * way to map the points on its surface to the pixels in an image. Built-in
 * shapes such as <a href="#/p5/rect">rect()</a> and
 * <a href="#/p5/box">box()</a> already have these texture mappings based on
 * their vertices. Custom shapes created with
 * <a href="#/p5/vertex">vertex()</a> require texture mappings to be passed as
 * uv coordinates.
 *
 * Each call to <a href="#/p5/vertex">vertex()</a> must include 5 arguments,
 * as in `vertex(x, y, z, u, v)`, to map the vertex at coordinates `(x, y, z)`
 * to the pixel at coordinates `(u, v)` within an image. For example, the
 * corners of a rectangular image are mapped to the corners of a rectangle by default:
 *
 * ```js
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * rect(0, 0, 30, 50);
 * ```
 *
 * If the image in the code snippet above has dimensions of 300 x 500 pixels,
 * the same result could be achieved as follows:
 *
 * ```js
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * beginShape();
 *
 * // Top-left.
 * // u: 0, v: 0
 * vertex(0, 0, 0, 0, 0);
 *
 * // Top-right.
 * // u: 300, v: 0
 * vertex(30, 0, 0, 300, 0);
 *
 * // Bottom-right.
 * // u: 300, v: 500
 * vertex(30, 50, 0, 300, 500);
 *
 * // Bottom-left.
 * // u: 0, v: 500
 * vertex(0, 50, 0, 0, 500);
 *
 * endShape();
 * ```
 *
 * `textureWrap()` controls how textures behave when their uv's go beyond the
 * texture. Doing so can produce interesting visual effects such as tiling.
 * For example, the custom shape above could have u-coordinates are greater
 * than the image’s width:
 *
 * ```js
 * // Apply the image as a texture.
 * texture(img);
 *
 * // Draw the rectangle.
 * beginShape();
 * vertex(0, 0, 0, 0, 0);
 *
 * // Top-right.
 * // u: 600
 * vertex(30, 0, 0, 600, 0);
 *
 * // Bottom-right.
 * // u: 600
 * vertex(30, 50, 0, 600, 500);
 *
 * vertex(0, 50, 0, 0, 500);
 * endShape();
 * ```
 *
 * The u-coordinates of 600 are greater than the texture image’s width of 300.
 * This creates interesting possibilities.
 *
 * The first parameter, `wrapX`, accepts three possible constants. If `CLAMP`
 * is passed, as in `textureWrap(CLAMP)`, the pixels at the edge of the
 * texture will extend to the shape’s edges. If `REPEAT` is passed, as in
 * `textureWrap(REPEAT)`, the texture will tile repeatedly until reaching the
 * shape’s edges. If `MIRROR` is passed, as in `textureWrap(MIRROR)`, the
 * texture will tile repeatedly until reaching the shape’s edges, flipping
 * its orientation between tiles. By default, textures `CLAMP`.
 *
 * The second parameter, `wrapY`, is optional. It accepts the same three
 * constants, `CLAMP`, `REPEAT`, and `MIRROR`. If one of these constants is
 * passed, as in `textureWRAP(MIRROR, REPEAT)`, then the texture will `MIRROR`
 * horizontally and `REPEAT` vertically. By default, `wrapY` will be set to
 * the same value as `wrapX`.
 *
 * Note: `textureWrap()` can only be used in WebGL mode.
 *
 * @method textureWrap
 * @param {Constant} wrapX either CLAMP, REPEAT, or MIRROR
 * @param {Constant} [wrapY] either CLAMP, REPEAT, or MIRROR

 * is glowing. However, emissive materials don’t actually emit light that
 * can affect surrounding objects.
 *
 * `emissiveMaterial()` can be called three ways with different parameters to
 * set the material’s color.
 *
 * The first way to call `emissiveMaterial()` has one parameter, `gray`.
 * Grayscale values between 0 and 255, as in `emissiveMaterial(50)`, can be
 * passed to set the material’s color. Higher grayscale values make shapes
 * appear brighter.
 *
 * The second way to call `emissiveMaterial()` has one parameter, `color`. A
 * <a href="#/p5.Color">p5.Color</a> object, an array of color values, or a
 * CSS color string, as in `emissiveMaterial('magenta')`, can be passed to set
 * the material’s color.
 *
 * The third way to call `emissiveMaterial()` has four parameters, `v1`, `v2`,
 * `v3`, and `alpha`. `alpha` is optional. RGBA, HSBA, or HSLA values can be
 * passed to set the material’s colors, as in `emissiveMaterial(255, 0, 0)` or
 * `emissiveMaterial(255, 0, 0, 30)`. Color values will be interpreted using
 * the current <a href="#/p5/colorMode">colorMode()</a>.
 *
 * Note: `emissiveMaterial()` can only be used in WebGL mode.

 * Sets the position and orientation of the current camera in a 3D sketch.
 *
 * `camera()` allows objects to be viewed from different angles. It has nine
 * parameters that are all optional.
 *
 * The first three parameters, `x`, `y`, and `z`, are the coordinates of the
 * camera’s position. For example, calling `camera(0, 0, 0)` places the camera
 * at the origin `(0, 0, 0)`. By default, the camera is placed at
 * `(0, 0, 800)`.
 *
 * The next three parameters, `centerX`, `centerY`, and `centerZ` are the
 * coordinates of the point where the camera faces. For example, calling
 * `camera(0, 0, 0, 10, 20, 30)` places the camera at the origin `(0, 0, 0)`
 * and points it at `(10, 20, 30)`. By default, the camera points at the
 * origin `(0, 0, 0)`.
 *
 * The last three parameters, `upX`, `upY`, and `upZ` are the components of
 * the "up" vector. The "up" vector orients the camera’s y-axis. For example,
 * calling `camera(0, 0, 0, 10, 20, 30, 0, -1, 0)` places the camera at the
 * origin `(0, 0, 0)`, points it at `(10, 20, 30)`, and sets the "up" vector
 * to `(0, -1, 0)` which is like holding it upside-down. By default, the "up"
 * vector is `(0, 1, 0)`.
 *
 * Note: `camera()` can only be used in WebGL mode.

 * Sets a perspective projection for the current camera in a 3D sketch.
 *
 * In a perspective projection, shapes that are further from the camera appear
 * smaller than shapes that are near the camera. This technique, called
 * foreshortening, creates realistic 3D scenes. It’s applied by default in
 * WebGL mode.
 *
 * `perspective()` changes the camera’s perspective by changing its viewing
 * frustum. The frustum is the volume of space that’s visible to the camera.
 * Its shape is a pyramid with its top cut off. The camera is placed where
 * the top of the pyramid should be and views everything between the frustum’s
 * top (near) plane and its bottom (far) plane.
 *
 * The first parameter, `fovy`, is the camera’s vertical field of view. It’s
 * an angle that describes how tall or narrow a view the camera has. For
 * example, calling `perspective(0.5)` sets the camera’s vertical field of
 * view to 0.5 radians. By default, `fovy` is calculated based on the sketch’s
 * height and the camera’s default z-coordinate, which is 800. The formula for
 * the default `fovy` is `2 * atan(height / 2 / 800)`.
 *
 * The second parameter, `aspect`, is the camera’s aspect ratio. It’s a number
 * that describes the ratio of the top plane’s width to its height. For
 * example, calling `perspective(0.5, 1.5)` sets the camera’s field of view to
 * 0.5 radians and aspect ratio to 1.5, which would make shapes appear thinner
 * on a square canvas. By default, aspect is set to `width / height`.
 *
 * The third parameter, `near`, is the distance from the camera to the near
 * plane. For example, calling `perspective(0.5, 1.5, 100)` sets the camera’s
 * field of view to 0.5 radians, its aspect ratio to 1.5, and places the near
 * plane 100 pixels from the camera. Any shapes drawn less than 100 pixels
 * from the camera won’t be visible. By default, near is set to `0.1 * 800`,
 * which is 1/10th the default distance between the camera and the origin.
 *
 * The fourth parameter, `far`, is the distance from the camera to the far
 * plane. For example, calling `perspective(0.5, 1.5, 100, 10000)` sets the
 * camera’s field of view to 0.5 radians, its aspect ratio to 1.5, places the
 * near plane 100 pixels from the camera, and places the far plane 10,000
 * pixels from the camera. Any shapes drawn more than 10,000 pixels from the
 * camera won’t be visible. By default, far is set to `10 * 800`, which is 10
 * times the default distance between the camera and the origin.

 * these modes, stroke weight is affected by the line’s distance from the
 * camera. Doing so results in a more natural appearance. `perspective()` is

 * - `ortho()` doesn’t simulate a realistic perspective. In this mode, stroke
 * weights are consistent regardless of the line’s distance from the camera.
 * Doing so results in a more predictable and consistent appearance.

 * Sets the frustum of the current camera in a 3D sketch.
 *
 * In a frustum projection, shapes that are further from the camera appear
 * smaller than shapes that are near the camera. This technique, called
 * foreshortening, creates realistic 3D scenes.
 *
 * `frustum()` changes the default camera’s perspective by changing its
 * viewing frustum. The frustum is the volume of space that’s visible to the
 * camera. The frustum’s shape is a pyramid with its top cut off. The camera
 * is placed where the top of the pyramid should be and points towards the
 * base of the pyramid. It views everything within the frustum.
 *
 * The first four parameters, `left`, `right`, `bottom`, and `top`, set the
 * coordinates of the frustum’s sides, bottom, and top. For example, calling
 * `frustum(-100, 100, 200, -200)` creates a frustum that’s 200 pixels wide
 * and 400 pixels tall. By default, these coordinates are set based on the
 * sketch’s width and height, as in
 * `ortho(-width / 20, width / 20, height / 20, -height / 20)`.
 *
 * The last two parameters, `near` and `far`, set the distance of the
 * frustum’s near and far plane from the camera. For example, calling
 * `ortho(-100, 100, 200, -200, 50, 1000)` creates a frustum that’s 200 pixels
 * wide, 400 pixels tall, starts 50 pixels from the camera, and ends 1,000
 * pixels from the camera. By default, near is set to `0.1 * 800`, which is
 * 1/10th the default distance between the camera and the origin. `far` is set
 * to `10 * 800`, which is 10 times the default distance between the camera
 * and the origin.
 *
 * Note: `frustum()` can only be used in WebGL mode.
 *
 * @method frustum
 * @for p5
 * @param  {Number} [left]   x-coordinate of the frustum’s left plane. Defaults to `-width / 20`.
 * @param  {Number} [right]  x-coordinate of the frustum’s right plane. Defaults to `width / 20`.
 * @param  {Number} [bottom] y-coordinate of the frustum’s bottom plane. Defaults to `height / 20`.
 * @param  {Number} [top]    y-coordinate of the frustum’s top plane. Defaults to `-height / 20`.
 * @param  {Number} [near]   z-coordinate of the frustum’s near plane. Defaults to `0.1 * 800`.
 * @param  {Number} [far]    z-coordinate of the frustum’s far plane. Defaults to `10 * 800`.

 * A class to describe a camera for viewing a 3D sketch.
 *
 * Each `p5.Camera` object represents a camera that views a section of 3D
 * space. It stores information about the camera’s position, orientation, and
 * projection.
 *
 * In WebGL mode, the default camera is a `p5.Camera` object that can be
 * controlled with the <a href="#/p5/camera">camera()</a>,
 * <a href="#/p5/perspective">perspective()</a>,
 * <a href="#/p5/ortho">ortho()</a>, and

 * with <a href="#/p5/setCamera">setCamera()</a>.
 *
 * Note: `p5.Camera`’s methods operate in two coordinate systems:
 * - The “world” coordinate system describes positions in terms of their
 * relationship to the origin along the x-, y-, and z-axes. For example,
 * calling `myCamera.setPosition()` places the camera in 3D space using
 * "world" coordinates.
 * - The "local" coordinate system describes positions from the camera's point
 * of view: left-right, up-down, and forward-backward. For example, calling
 * `myCamera.move()` moves the camera along its own axes.

          // Camera Projection Methods
          ////////////////////////////////////////////////////////////////////////////////
          /**
  * Sets a perspective projection for the camera.
  *
  * In a perspective projection, shapes that are further from the camera appear
  * smaller than shapes that are near the camera. This technique, called
  * foreshortening, creates realistic 3D scenes. It’s applied by default in new
  * `p5.Camera` objects.
  *
  * `myCamera.perspective()` changes the camera’s perspective by changing its
  * viewing frustum. The frustum is the volume of space that’s visible to the
  * camera. The frustum’s shape is a pyramid with its top cut off. The camera
  * is placed where the top of the pyramid should be and points towards the
  * base of the pyramid. It views everything within the frustum.
  *
  * The first parameter, `fovy`, is the camera’s vertical field of view. It’s
  * an angle that describes how tall or narrow a view the camera has. For
  * example, calling `myCamera.perspective(0.5)` sets the camera’s vertical
  * field of view to 0.5 radians. By default, `fovy` is calculated based on the
  * sketch’s height and the camera’s default z-coordinate, which is 800. The
  * formula for the default `fovy` is `2 * atan(height / 2 / 800)`.
  *
  * The second parameter, `aspect`, is the camera’s aspect ratio. It’s a number
  * that describes the ratio of the top plane’s width to its height. For
  * example, calling `myCamera.perspective(0.5, 1.5)` sets the camera’s field
  * of view to 0.5 radians and aspect ratio to 1.5, which would make shapes
  * appear thinner on a square canvas. By default, `aspect` is set to
  * `width / height`.
  *
  * The third parameter, `near`, is the distance from the camera to the near
  * plane. For example, calling `myCamera.perspective(0.5, 1.5, 100)` sets the
  * camera’s field of view to 0.5 radians, its aspect ratio to 1.5, and places
  * the near plane 100 pixels from the camera. Any shapes drawn less than 100
  * pixels from the camera won’t be visible. By default, `near` is set to
  * `0.1 * 800`, which is 1/10th the default distance between the camera and
  * the origin.
  *
  * The fourth parameter, `far`, is the distance from the camera to the far
  * plane. For example, calling `myCamera.perspective(0.5, 1.5, 100, 10000)`
  * sets the camera’s field of view to 0.5 radians, its aspect ratio to 1.5,
  * places the near plane 100 pixels from the camera, and places the far plane
  * 10,000 pixels from the camera. Any shapes drawn more than 10,000 pixels
  * from the camera won’t be visible. By default, `far` is set to `10 * 800`,
  * which is 10 times the default distance between the camera and the origin.
  *

    *
    * In an orthographic projection, shapes with the same size always appear the
    * same size, regardless of whether they are near or far from the camera.
    *
    * `myCamera.ortho()` changes the camera’s perspective by changing its viewing
    * frustum from a truncated pyramid to a rectangular prism. The frustum is the
    * volume of space that’s visible to the camera. The camera is placed in front
    * of the frustum and views everything within the frustum. `myCamera.ortho()`
    * has six optional parameters to define the viewing frustum.
    *
    * The first four parameters, `left`, `right`, `bottom`, and `top`, set the
    * coordinates of the frustum’s sides, bottom, and top. For example, calling
    * `myCamera.ortho(-100, 100, 200, -200)` creates a frustum that’s 200 pixels
    * wide and 400 pixels tall. By default, these dimensions are set based on
    * the sketch’s width and height, as in
    * `myCamera.ortho(-width / 2, width / 2, -height / 2, height / 2)`.
    *
    * The last two parameters, `near` and `far`, set the distance of the
    * frustum’s near and far plane from the camera. For example, calling
    * `myCamera.ortho(-100, 100, 200, -200, 50, 1000)` creates a frustum that’s
    * 200 pixels wide, 400 pixels tall, starts 50 pixels from the camera, and
    * ends 1,000 pixels from the camera. By default, `near` and `far` are set to
    * 0 and `max(width, height) + 800`, respectively.
    *
    * @method ortho
    * @for p5.Camera
    * @param  {Number} [left]   x-coordinate of the frustum’s left plane. Defaults to `-width / 2`.
    * @param  {Number} [right]  x-coordinate of the frustum’s right plane. Defaults to `width / 2`.
    * @param  {Number} [bottom] y-coordinate of the frustum’s bottom plane. Defaults to `height / 2`.
    * @param  {Number} [top]    y-coordinate of the frustum’s top plane. Defaults to `-height / 2`.
    * @param  {Number} [near]   z-coordinate of the frustum’s near plane. Defaults to 0.
    * @param  {Number} [far]    z-coordinate of the frustum’s far plane. Defaults to `max(width, height) + 800`.

    * The next three parameters, `centerX`, `centerY`, and `centerZ` are the
    * coordinates of the point where the camera faces in "world" space. For
    * example, calling `myCamera.camera(0, 0, 0, 10, 20, 30)` places the camera
    * at the origin `(0, 0, 0)` and points it at `(10, 20, 30)`. By default, the
    * camera points at the origin `(0, 0, 0)`.
    *
    * The last three parameters, `upX`, `upY`, and `upZ` are the components of
    * the "up" vector in "local" space. The "up" vector orients the camera’s
    * y-axis. For example, calling
    * `myCamera.camera(0, 0, 0, 10, 20, 30, 0, -1, 0)` places the camera at the
    * origin `(0, 0, 0)`, points it at `(10, 20, 30)`, and sets the "up" vector
    * to `(0, -1, 0)` which is like holding it upside-down. By default, the "up"
    * vector is `(0, 1, 0)`.

 * A class to describe a 3D shape.
 *
 * Each `p5.Geometry` object represents a 3D shape as a set of connected
 * points called *vertices*. All 3D shapes are made by connecting vertices to
 * form triangles that are stitched together. Each triangular patch on the
 * geometry's surface is called a *face*. The geometry stores information
 * about its vertices and faces for use with effects such as lighting and
 * texture mapping.
 *
 * The first parameter, `detailX`, is optional. If a number is passed, as in
 * `new p5.Geometry(24)`, it sets the number of triangle subdivisions to use
 * along the geometry's x-axis. By default, `detailX` is 1.
 *
 * The second parameter, `detailY`, is also optional. If a number is passed,
 * as in `new p5.Geometry(24, 16)`, it sets the number of triangle
 * subdivisions to use along the geometry's y-axis. By default, `detailX` is
 * 1.
 *
 * The third parameter, `callback`, is also optional. If a function is passed,
 * as in `new p5.Geometry(24, 16, createShape)`, it will be called once to add
 * vertices to the new 3D shape.
 *
 * @class p5.Geometry
 * @constructor
 * @param  {Integer} [detailX] number of vertices along the x-axis.
 * @param  {Integer} [detailY] number of vertices along the y-axis.
 * @param {function} [callback] function to call once the geometry is created.

     * of the face and is normal (perpendicular) to the surface. Calling
     * `myGeometry.computeNormals()` first calculates each face's normal vector.
     * Then it calculates the normal vector for each vertex by averaging the
     * normal vectors of the faces surrounding the vertex. The vertex normals
     * are stored as <a href="#/p5.Vector">p5.Vector</a> objects in the
     * <a href="#/p5.Geometry/vertexNormals">myGeometry.vertexNormals</a> array.
     *
     * The first parameter, `shadingType`, is optional. Passing the constant
     * `FLAT`, as in `myGeometry.computeNormals(FLAT)`, provides neighboring
     * faces with their own copies of the vertices they share. Surfaces appear
     * tiled with flat shading. Passing the constant `SMOOTH`, as in
     * `myGeometry.computeNormals(SMOOTH)`, makes neighboring faces reuse their
     * shared vertices. Surfaces appear smoother with smooth shading. By
     * default, `shadingType` is `FLAT`.
     *
     * The second parameter, `options`, is also optional. If an object with a
     * `roundToPrecision` property is passed, as in
     * `myGeometry.computeNormals(SMOOTH, { roundToPrecision: 5 })`, it sets the
     * number of decimal places to use for calculations. By default,

 * default is false (true in Safari)
 *
 * premultipliedAlpha - indicates that the page compositor will assume
 * the drawing buffer contains colors with pre-multiplied alpha
 * default is true
 *
 * preserveDrawingBuffer - if true the buffers will not be cleared and
 * and will preserve their values until cleared or overwritten by author
 * (note that p5 clears automatically on draw loop)
 * default is true
 *
 * perPixelLighting - if true, per-pixel lighting will be used in the
 * lighting shader otherwise per-vertex lighting is used.
 * default is true.
 *
 * version - either 1 or 2, to specify which WebGL version to ask for. By
 * default, WebGL 2 will be requested. If WebGL2 is not available, it will
 * fall back to WebGL 1. You can check what version is used with by looking at
 * the global `webglVersion` property.

   */
        /**
 * A class to describe a shader program.
 *
 * Each `p5.Shader` object contains a shader program that runs on the graphics
 * processing unit (GPU). Shaders can process many pixels or vertices at the
 * same time, making them fast for many graphics tasks. They’re written in a
 * language called
 * <a href="https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders" target="_blank">GLSL</a>
 * and run along with the rest of the code in a sketch.
 *
 * A shader program consists of two files, a vertex shader and a fragment
 * shader. The vertex shader affects where 3D geometry is drawn on the screen
 * and the fragment shader affects color. Once the `p5.Shader` object is
 * created, it can be used with the <a href="#/p5/shader">shader()</a>
 * function, as in `shader(myShader)`.
 *
 * A shader can optionally describe *hooks,* which are functions in GLSL that
 * users may choose to provide to customize the behavior of the shader. For the
 * vertex or the fragment shader, users can pass in an object where each key is
 * the type and name of a hook function, and each value is a string with the
 * parameter list and default implementation of the hook. For example, to let users
 * optionally run code at the start of the vertex shader, the options object could
 * include:
 *
 * ```js
 * {
 *   vertex: {
 *     'void beforeVertex': '() {}'
 *   }
 * }
 * ```
 *
 * Then, in your vertex shader source, you can run a hook by calling a function
 * with the same name prefixed by `HOOK_`:
 *
 * ```glsl
 * void main() {
 *   HOOK_beforeVertex();
 *   // Add the rest ofy our shader code here!
 * }
 * ```
 *
 * Note: <a href="#/p5/createShader">createShader()</a>,
 * <a href="#/p5/createFilterShader">createFilterShader()</a>, and
 * <a href="#/p5/loadShader">loadShader()</a> are the recommended ways to
 * create an instance of this class.
 *
 * @class p5.Shader
 * @constructor
 * @param {p5.RendererGL} renderer WebGL context for this shader.
 * @param {String} vertSrc source code for the vertex shader program.
 * @param {String} fragSrc source code for the fragment shader program.
 * @param {Object} [options] An optional object describing how this shader can
 * be augmented with hooks. It can include:
 *  - `vertex`: An object describing the available vertex shader hooks.
 *  - `fragment`: An object describing the available frament shader hooks.

     * Returns a new shader, based on the original, but with custom snippets
     * of shader code replacing default behaviour.
     *
     * Each shader may let you override bits of its behavior. Each bit is called
     * a *hook.* A hook is either for the *vertex* shader, if it affects the
     * position of vertices, or in the *fragment* shader, if it affects the pixel
     * color. You can inspect the different hooks available by calling
     * <a href="#/p5.Shader/inspectHooks">`yourShader.inspectHooks()`</a>. You can
     * also read the reference for the default material, normal material, color, line, and point shaders to
     * see what hooks they have available.
     *
     * `modify()` takes one parameter, `hooks`, an object with the hooks you want
     * to override. Each key of the `hooks` object is the name
     * of a hook, and the value is a string with the GLSL code for your hook.
     *
     * If you supply functions that aren't existing hooks, they will get added at the start of
     * the shader as helper functions so that you can use them in your hooks.
     *
     * To add new <a href="#/p5.Shader/setUniform">uniforms</a> to your shader, you can pass in a `uniforms` object containing
     * the type and name of the uniform as the key, and a default value or function returning
     * a default value as its value. These will be automatically set when the shader is set
     * with `shader(yourShader)`.
     *
     * You can also add a `declarations` key, where the value is a GLSL string declaring
     * custom uniform variables, globals, and functions shared
     * between hooks. To add declarations just in a vertex or fragment shader, add
     * `vertexDeclarations` and `fragmentDeclarations` keys.
