Sprite rotation

Are there any plans to introduce an ability to rotate sprites added to the sprite batch?

In theory, it should be pretty easily done by introducing something like `RotationRect` as an extension of `Rect`, which will contain additional info about the angle and origin of rotation. Later this `RotationRect` may be used by calling `batch.add_rotated`.
As an alternative, it might be a good solution to go "XNA" way by adding both angle and origin to the direct `batch.add` call.
