[Paraview] Saving screen shots of multiple views from an animation with python

[Berk Geveci]

Utkarsh would know this best but I think you have at lease two choices:

* Run the animation multiple times, one for each view. I am guessing that there
is a way of setting which view is saved.
* Run the animation manually (still using the animation scene) and save the
views yourself.
