[Paraview] Multiple polydata in same pipeline -- don't always seem centered around same origin

[Sohail Shafii]

Thanks. Changing the setting "Coincident Topology Resolution" to "Do Nothing" made it work.

ParaView draws points and lines slightly offset so that you see
wireframes on top of surfaces.

Try playing with Edit->Settings->Render View->General->Coincident
Topology Resolution to change this behavior.
