[vtkusers] vtkPlaneWidget and clipping

[Bertwim van Beest]

This is what I do not understand here.  I do not know to invert the 
clipping function. I use "AddClippingPlane" on an instance of 
vtkDataSetMapper:

_mapper = vtkDataSetMapper::New();
 ...
  _mapper->AddClippingPlane( _plane );

Where is the ClipPolydata?
