    * A BitmapData object contains a Canvas element to which you can draw anything you like via normal Canvas context operations.
    * A single BitmapData can be used as the texture for one or many Images / Sprites.
    * So if you need to dynamically create a Sprite texture then they are a good choice.
    *
    * Important note: Every BitmapData creates its own Canvas element. Because BitmapData's are now Game Objects themselves, and don't
    * live on the display list, they are NOT automatically cleared when you change State. Therefore you _must_ call BitmapData.destroy
    * in your State's shutdown method if you wish to free-up the resources the BitmapData used, it will not happen for you.
    *
