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

Interesting. Although I am not sure if the mesa developers simply mean
that you can build libGL and libOSMesa at the same time (which is
indeed possible). But worth a try. I will test it out with the latest
mesa and get back to the list. I am positive this didn't work with the
7.* series.
