[Paraview] Using CUDA accelerated vtkm filter

[Robert Maynard]

Hi Sumin,

So it looks like the fix will require you to either build ParaView from
gitlab ( https://gitlab.kitware.com/paraview/paraview ) as the official
releases have a bug which has been fixed. If you have been building from
the release sources, building from git is very similar (
https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md
).
