/**
 * A shader effect that pulses a color overlay on the sprite.
 * Commonly used for status effects — poison green, freeze blue, fire red.
 * The `time` uniform should be updated each frame for the pulse animation.
 * @category Effects
 * @see {@link Renderable.shader} for usage
 * @example
 * // poison pulse
 * const poison = new TintPulseEffect(renderer, {
 *     color: [0.0, 1.0, 0.0],
 *     speed: 3.0,
 * });
 * mySprite.shader = poison;
 *
 * // update each frame
 * poison.setTime(timer.getTime() / 1000);
