[Paraview] Recent Xdmf volume rendering

[Dominik Szczerba]

However: changing ExtractSubset parameters (output extents) at some 
point (after a few changes) "propagates" upstream, i.e., the original 
dataset "inherits" the extents of the downstream filter (gets 
truncated). This is clearly wrong, but probably unrelated to this topic.

BTW. For a longer while I have been observing dramatic drop in PV 
usability. Average time before crashes is only a few minutes. I am 
basically scared to touch anything once I set up my pipeline (change 
names of calculator variables, extents of VOI etc. etc.). My last resort 
of using save states is now failing too, it is usually impossible to 
reload the state (segmentation faults).
