[Paraview] Two questions regarding animations in batch

[Morten Olsen]

Thank you, Utkarsh! It tried CameraAnimationCue, but it still segfaulted
with the error "No camera to animate". Therefore, I added

Show(reader)
Render()

before creating a cue. Now it works. However, the resulting movie is just
one black frame lasting for a fraction of a second. How can I tell the
script to add the object itself to the movie and to do it for every frame?
I have over 100 frames in .vtk files.
