   Objects with pivot points have a position relative to their PP, so they have to undergo this transform:
 
     invert the mesh matrix, apply this matrix to the object. This puts the object back at the origin
-    Transform the object by the nodes (nnegative) pivot point coords, this puts the PP at the origin
-    Tranform the node by the node matrix, which does the orientation about the pivot point, (and currently) transforms the object back by a translation to the PP.
