Ah, this even fixes the first problem - it now works with the camera at
(0,0,1) as well. I guess I thought that lighting would be applied in pixel
space in the renderer rather than in "vtk cell" space (i.e. I didn't think
the underlying composition of the plane would have mattered for this).

Dmitir, let us know if this does not get you farther:

Thanks Bill!
