sub-extent handling missing for `vtkMarchingCubes` and `vtkDiscreteMarchingCubes`
It seems both
vtkMarchingCubes do not handle the translation of each sub-extent if running
vtkStreamingDemandDrivenPipeline, e.g. MPI. If the result is saved in a PVTP-file and opened in ParaView, the content of each VTP-file is placed over the others.
In contrast vtkContourFilter does handle the translation of each sub-extent correctly, the content of each VTP-file is positioned correctly.
This Issue refers to the mailing list communication with @lorensen (http://public.kitware.com/pipermail/vtkusers/2015-November/093060.html)
