[Paraview] pqMultiSliceView bug?

[Sebastien Jourdain]

ParaView will always set it by default to (0,0,0), although the user can
override it from the python if it wants to.
A use case, could be if your data is not centered on (0,0,0) and you want
the offset of be relative to your dataset.
But this really depends on the user goal. The ParaView UI is made to work
with origin set to (0,0,0)
