[Paraview] How to get the vtkPolyData from ParaView representations?

[Utkarsh Ayachit]

The short answer is you can't. However if you don't care about this
code working in client-server mode, then you can do something like
follows:
vtkPVDataRepresentation* rep =   repProxy->GetClientSideObject();
vtkDataObject* dobj = rep->GetRenderedDataObject(0);
