[vtkusers] Offscreen rendering

[John Norris]

Progress!  I can render offscreen, but it still requires a connection to
an X server.  This is despite the fact that I'm setting
vtkGraphicsFactory::OffScreenOnlyMode to 1.  Either it's not working as
advertised (the program still makes X calls), or there's some CMake
option that I need to set.

Is there any possible way to render offscreen in Unix without connecting
to an X server?

This is with straight OpenGL, no Mesa.  I could never get that to work
at all.
