[vtkusers] Extracting normals from polydata add points ?

[Nicolas Cedilnik]

Hi again,

…and that was it. It's a feature I didn't pay attention to.

My next question would be: does turning this off affects normal values
of the pre-existing points ?
Should I leave it on and filter the result to the first n points as I
did before for better normals estimation ?

Thanks !
