[Paraview] Is there any point to compiling with MPI but without offscreen rendering?

[Utkarsh Ayachit]

Kevin,

I gave using GL and OSMesa together using Mesa-9.0.1 with a ParaView
3.14.1 a try and unfortunately it still segfaults when creating a
context when using OSMesa -- consistent with the behavior before glapi
library was created. So alas, doesn't look like we can use  onscreen
and offscreen Mesa together as in the pre Mesa-7.9 days.
