I trying VisIt a while back and preferred the Paraview interface, but
I'll give it another look.

I'll look into it.

I understand the 3rd argument (requested_entity_type) is ignored if the
4th (requested_entity_topology) is more specific.  However, the 5th
(entity_adjacency_type) is never referenced (see iMesh_MOAB.cpp:536).
