[Paraview] Change the coordinates of a 3D Point

[David E DeMarle]

Think of fetch and the python shell in general as working on copies of the
data in the client. Changes to the copy won't persist. The way it showed up
in the spreadsheet view is kind of fluke.

Try the python programmable filter which works on the data where it lives
on the server. The output of that filter will reflect the changes.
