This may be possible. You would have to change the PetscViewerVTKFieldType
to be bitflags. After that,
I am not sure if anything would break in the routine. I don't have much
time right now, but I will look at it
later if no one else gets to it.

  Thanks,

experiments is infinitely more interesting than any results to which their
experiments lead.
