[vtkusers] Blanking a point in a vtkStructuredGrid

Is it possible to have the mapper skip drawing the points that have
been "blanked" in a structured grid? For example, in this example:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/StructuredGrid/BlankPoint

The point that is not on the plane with the rest of the points has
been blanked with this line:

  structuredGrid->BlankPoint(27);

yet it still appears in the renderer (along with the polygon cells
that attach it to its neighbors). Can anyone explain how to do this
correctly, or correct my misunderstanding of what blanking is supposed
to do?

Thanks,

David
