[Paraview] Remote rendering with pvpython + grab remote image data

[Kolja Petersen]

I found that simple.WriteImage(...) solves the second part of my problem,
which is to grab the image data.

But I have still no clue how to make the pvserver render the scene remotely
and only transfer the rendered image to the pvpython client instead of all
3D datasets (which will be huge).

Any help?
