[Paraview] pvserver through ssh tunnel

[David E DeMarle]

The files should be resident near the server, so compression won't affect
them (unless you are doing something in the Cloud, in which case I can't
help you).

For compression and its relationship to remote rendering, try the various
presets on [Preferences|Settings]->Render View->Server
