[Paraview] Saving movie offscreen

[Berk Geveci]

I suggest compiling a paraview with Mesa enabling
VTK_OPENGL_HAS_OSMESA for doing this. Make sure that you do not
comment out the line that enables offscreen rendering for this build.
You can then save animation either as usual using the GUI or save the
state and load it from a python script to generate the animation in
batch.
