[Paraview] OpenGL2 and ParaView 4.3.1 ...

[Aashish Chaudhary]

Yes, We have paraview working* with OpenGL2 backend. In some cases you may
run into bugs but its getting there.

on vtkHAVSVolumeMapper, what SHA of ParaView you are using? We took care of
this issue sometime back and I have not seen this error since then. Also,
what dataset (format) you are using?

Thanks,
