[Paraview-developers] osmesa version of ParaView

[Ken Martin]

Couple quick thoughts

If we can connect to the remote display using GLX (but not forwarded) then
we can render remotely (offscreen but using normal OpenGL) and then copy
the result to an Xwindow which is forwarded to a local machine. Sort of a
RenderingDisplay=:0.0 Display=:1.0 where 1.0 is the forwarded one.

I recall there being an issue with osmesa and accelerated opengl in the
same binary but I have very limited experience with it.
