[vtkusers] vtkAssembly Set/Get Position

[Christopher M. Navarro]

If I add 2 actors to a vtkAssembly object, set the position of the 
vtkAssembly object via its SetPosition method, then request the 2 actors 
positions via GetPosition() on each actor, they return 0.0, 0.0, 0.0.  
Only the assembly object returns the position set.  Is this expected 
behavior?  If I then set the actors to the position of the assembly, they 
move slightly when the next Render is called.  If this is expected 
behavior, is there a way to get what each actors equivalent position would 
be?  I want to be able to send vtkPolyData over a socket and recreate the 
scene as it appears on the client machine by sending position, scale, etc 
over the socket.  If I only send data for one of the two actors, I would 
like it to appear on the server machine as it was on the client.  If I send the 
assembly's position, it will not match the position it had on the client 
side.  Any ideas how to get the equivalent position in space?
