[Paraview] XDMF using ORIGIN_DXDYDZ switches X- and Z-dimension

[Jens]

Hi Jerry,

so ORIGIN_DXDYDZ is not related to XYZ of ParaView, but defines its own
XYZ-xdmf.

But why is hdf5-Z the slowest changing dimension and therefor xdmf-X?
HDF5 is written in C++ and therefor hdf5-X should be the slowest
changing dimension.

Anyway, I hope I finally understood it :)

Greetings
Jens
