[Paraview] Saving movie offscreen

[Utkarsh Ayachit]

If you can run pvserver on your powerful desktop and connect to it with 
the paraview client running on the laptop, then there's another option 
for you to save animation overnight without the laptop connected:

Note that in this configuration you are no longer forwarding X to your 
laptop using "ssh -X". With the client connected to the server on your 
desktop, set up your scene. Now when you go to the save animation 
dialog, the "Disconnect before saving animation" check box should be 
enabled. When checked, the client disconnects from  the server before 
saving of the animation begins. After the client has disconnected, the 
server still continues running until it has finished saving out the 
animation.
