[Paraview] pvbatch offscreen rendering problems

[Utkarsh Ayachit]

I was writing a response when it struck me, are you building with
PARAVIEW_BUILD_QT_GUI ON? That's possible the only difference between
your build and mine. I am going to turn on PARAVIEW_BUILD_QT_GUI and
try to reproduce the problem.
