/** A Sprite subclass that is bound to a physics body.
It works with:
- Chipmunk: Preprocessor macro CC_ENABLE_CHIPMUNK_INTEGRATION should be defined
- Objective-Chipmunk: Preprocessor macro CC_ENABLE_CHIPMUNK_INTEGRATION should be defined
- Box2d: Preprocessor macro CC_ENABLE_BOX2D_INTEGRATION should be defined
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
