[vtkusers] How do I move multiple actors on the same window?

[Wes Turner]

Taro,

The default interaction mode for VTK is to move the camera not the actors,
which makes it appear that all the actors move simultaneously.  To actually
interact with the actors, I believe you need to hit the 'a' key (I also
believe returning to camera interaction requires that you hit the 'c' key).
