[Paraview] gpu_shader4 extension is not supported

[Burlen Loring]

Hi Patrick,

OSMesa (and friends such as OpenSWR) do not need to make use of GLX. In 
fact I think it should be disabled completely for that case in both Mesa 
and ParaView builds. For eg, when you configure ParaView you'd specify 
-DVTK_USE_X=OFF. At least this is how it was in the past. I haven't been 
following developments lately. The wiki 
<http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D> has specifics.
