//     Function : get_global_pose_optimized
//       Access : Published
//  Description : This is an optimized version of get_global_pose that
//                copies the pose data to a passed matrix rather than
//                returning a new matrix, and also optimizes the
//                translation from PhysX matrix to Panda matrix.
//                It is primarily intended to be used by the
//                update_transform method, which is called in a tight
//                loop when transforms are copied from the PhysX
//                library to Panda.
