/**
 * @classdesc
 * A Sprite Game Object.
 *
 * A Sprite Game Object is used for the display of both static and animated images in your game.
 * Sprites can have input events and physics bodies. They can also be tweened, tinted, scrolled
 * and animated.
 *
 * The main difference between a Sprite and an Image Game Object is that you cannot animate Images.
 * As such, Sprites take a fraction longer to process and have a larger API footprint due to the Animation
 * Component. If you do not require animation then you can safely use Images to replace Sprites in all cases.
