/**
 * @classdesc
 * A Matter Physics Image Game Object.
 *
 * An Image is a light-weight Game Object useful for the display of static images in your game,
 * such as logos, backgrounds, scenery or other non-animated elements. Images can have input
 * events and physics bodies, or be tweened, tinted or scrolled. The main difference between an
 * Image and a Sprite is that you cannot animate an Image as they do not have the Animation component.
