Rotate and Rotate transformation

[Tom Eugelink]

Ok, thanks for confirming. It seemed overkill to roll-in Timeline only to animate a single property; IMHO Timeline is aimed at animation orchestration, so it does not feel right. Adding pivot X & Y to node would make the rotation property much more useful.
