/**
 * A shader effect that desaturates (grayscales) the sprite.
 * The `intensity` uniform controls how much color is removed
 * (0.0 = full color, 1.0 = fully grayscale).

 * @category Effects
 * @see {@link Renderable.shader} for usage
 * @example
 * // full grayscale
 * mySprite.shader = new DesaturateEffect(renderer);
 * @example
 * // partial desaturation (50%)
 * mySprite.shader = new DesaturateEffect(renderer, { intensity: 0.5 });
