 * A Sprite that wraps an animation so that a sequence of frames can be easily moved around the
 * screen. Animations embedded here should not be added directly to a media panel as this sprite
 * will manage them. If the enclosed animation completes, we remove the sprite from the media
 * panel, since the animation would normally do that itself.
