[Paraview] Displaying point coordinates

[Utkarsh Ayachit]

> There's a strange inconsistency, though: When I use the standard spreadsheet view (with points selected or not) for a default sphere source, I see Normals, Points & Point ID. If I select points on the sphere and click "Show only selected elements", only the Normals and Point ID show up as columns -- the Points coordinates disappear...

This was a big that I fixed just yesterday.
