[Paraview] pvbatch (3.8.0) rendering through OSmesa does not work on multiple nodes

[Dave Partyka]

We've stumbled upon the same issue. The most recent versions of OSMesa crash
when making multiple calls to MakeCurrent as they will attempt to create a
new render buffer each time. As Sven mentioned, it has been reported to the
Mesa Community. You can view our own findings related to this issue in these
VTK and ParaView bugs.

I would recommend using mesa 7.0.4 or 7.5.x until the issue is fixed
upstream.
