No--the only place where we do this at the moment is when we extrude a
surface mesh...

It shouldn't be too hard to implement, though. The best way would
probably be to add an optional parameter to the transformation commands
(Translate, Rotate, etc.), like the "Layer" stuff for extrusion commands.
