This doesn't work unfortunately, as PV turns it into a grid of
160x4096x4096 (and no data is visible at all, even though the number of
cells and points seems to be correct). I don't see where the reordering
of axes comes from. Looking at Utilities/Xdmf2/libsrc/XdmfGeometry.cxx I
think I got the Geometry stuff correct. Does anybody see what is wrong?
Ouch, seems I missed the line
"Dimensions are specified with the slowest varying dimension first (i.e.
KJI order)."
in the Xdmf spec...
