 /**
 * A collection of methods for displaying debug information about game objects.

+* to it, which must be uploaded every frame. Be advised: this is very expensive, especially in browsers like Firefox. So please only enable Debug

 * If your game is using a Canvas renderer then the debug information is literally drawn on the top of the active game canvas and no Sprite is used.
