[vtkusers] paraview crashes in VTK with > 2^31 points

[Berk Geveci]

Did you compile paraview with VTK_USE_64BIT_IDS? By default, VTK (and
hence ParaView) uses a signed int as n id type, restricting number of
points/cells to 2^31. If you compile with VTK_USE_64BIT_IDS turned on,
VTK will use the appropriate 64 bit integer as id type. However, there
are still some bugs where certain things do not work with 2^31. We
haven't tracked all of them down. If you run into issues, please post
a report on this list describing what happened in detail.
