* Use Blender structures so that BKE_pose_where_is can be used unchanged
* Copy the constraint so that they can be enabled/disabled/added/removed at runtime
* Don't copy the constraints for the pose used by the Action actuator, it does not need them.
* Scan the constraint structures so that the KX equivalent of target objects are identified and
* stored in separate list.
* When it is about to evaluate the pose, set the KX object position in the obmat of the corresponding
* Blender objects and restore after the evaluation.
