[vtkusers] vtkInteractor to only rotate on one axis?

[David Gobbi]

Hi Philip,

Try customizing vtkRenderWidget.py instead, it should be much easier.
Use the tk 'after' to drive animations.  The vtkInteractorStyleUser is
an ugly beast (though CustomInteraction.py works fine for me, the mouse
buttons rotate & zoom & move the plane).
