[Paraview] Assign scalars/vectors to mesh points in vtkRectilinearGrid, C++

[Andy Bauer]

Could you share your generated file? I'm not sure why the rescale to data
range is scaling it to the range [0,1]. Also, what version of ParaView are
you using?

Modifying the file won't cause ParaView to reread it as the reader will not
notice that the time stamp on the file has changed.
