I agree that it should be made clear in documentation, but again since
this is called on the vtkPoints of a dataset, it shouldn't introduce
polydata->GetPoints()->GetCentroid() should be clear that it is the
centroid of the points.
If it was just polydata->GetCentroid(), then it would be ambiguous.
