vtkMPIImageReader gives up instead of handling more than 2^31 elements.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
IO/MPIImage/vtkMPIImageReader.cxx's "ReadSlice" method checks for a large read and bails if this occurs. This presents users from reading "raw" data in ParaView if the dataset exceeds 2^31 elements.
The PNrrdReader had a similar issue; a fix is to loop reading VTK_INT_MAX elements at a time.
