VoiceVisualizer Widget for airunner integration
==============================================

This module provides a VoiceVisualizer widget that inherits from both
VoiceVisualizerComponent and BaseWidget for airunner integration.

The widget exposes advanced controls for shader parameters like intensity,
color properties, animation speed, and post-processing effects.

Features:
- Shader parameter control (intensity, color shift, animation speed, etc.)
- Post-processing effects (bloom, vignette, etc.)
- Audio device selection (planned)
- Performance tuning controls

All shader uniform methods work with the extended C++ interface:
- set_line_width(), set_intensity(), set_color_shift()
- set_bass_color(), set_mid_color(), set_treble_color()
- All other shader uniform methods

The widget automatically queues uniform changes when the shader is not ready
and applies them once the shader becomes active.
