/** A Sprite subclass that is bound to a physics body.
 It works with:
 - Box2D

 Features and Limitations:
 - Scale and Skew properties are ignored.
 - Position and rotation are going to updated from the physics body
 - If you update the rotation or position manually, the physics body will be updated
 - You can't enble both Chipmunk support and Box2d support at the same time. Only one can be enabled at compile time
