[Paraview] How to implement a multiview

[pat marion]

For a real solution I'd want to script it in python... the problem is that
you cannot easily specify the view layout in the gui from the python
interface.  Everything else can be done (creating views, camera links,
colormaps).  If you're interested, it might not be too hard to extend the
python interface to so that you can get the view layout that you want.
You'd have to get into paraview's qt code though.
