Visualization of uninterpolated DMPlex with hdf5 currently does not work. I
think the culprit is this line.
<https://bitbucket.org/petsc/petsc/src/aa0ba431d766d8676b0f511486aa700b6a8925ca/src/dm/impls/plex/plexhdf5.c?at=master&fileviewer=file-view-default#plexhdf5.c-303>Is
this to avoid duplicating output for the topology? If so, I think this is
wrong, because the dataset /topology/cells does not have the correct block
size and correct values (it outputs point numbers and not vertex numbers)
for visualization.

Thanks,
Sander
