[Paraview] Differences between OpenGL and OpenGL2 versions of ParaView

[Ken Martin]

Yes, thank goodness, I thought this dataset looked familiar. Now I remember
looking into this a while back and yes, the decision we landed on was as
you specified. The new code is different from the old version, but to me a
much safer and better approach. If the data is missing for a block we use
the solid color, not whatever the last used color happened to be from the
preceding block. Hopefully that explains it (fingers crossed).

Thanks
Ken
