[Paraview] vtkIdType of int for 64bit Linux binary of PV 3.6.1?

[Berk Geveci]

This is intentional. 64 bit ids are mainly useful for processing
really large structured datasets in a non-distributed way. Otherwise,
they are unnecessary but cause all data structures used to represent
unstructured data to bloat. Ideally, I would like to see this change
such that ids can be on 32 bit or 64 bit on a dataset to dataset
basis.
