Can delete cells from vtkPolyData?

[Tim Hutton]

I'm having a little trouble understanding what I'm doing wrong. I want to
perform a test on each cell in a vtkPolyData, to decide whether to delete
it or not. vtkPolyData::DeleteCell() seems to have no effect; when I
visualise the mesh all the cells are still there, even if I call it for all
of them! Help!

Tim.
