[Paraview] Why is pvbatch displaying images?

[Andy Bauer]

Yes, you don't need OSMesa when there is graphics hardware support. In that
case though it will still pop up a render window to create screen shots.
OSMesa can still be used even if you have graphics hardware support and is
currently the only way to get around having a window to render into.
