[Paraview] Recent Xdmf volume rendering

[Eric E. Monson]

That seems to work great now, Utkarsh -- Thanks for the fast fix!

Can someone please explain what the "with blanking" is, though -- Is it a way to mask out certain blocks, or something? Is this something that is supported within Xdmf? Not a huge issue, but I was just curious...

Thanks again,
-Eric
