[Paraview] Rendering Backend OpenGL2 & PV 5.2.0-RC4 & SurfaceLic --> Problem...

[Ken Martin]

Thanks for trying it out. I do want to fix the compositeLic to be fast as
 well.  It just has to be reworked to use the new always fast
compositePolyDataMapper2 approach.  I hope to get to it early next year.
Just wanted to  let you know.

Thanks
Ken
