[vtkusers] Cut a triangulated surface with a line

[Alex Malyushytskyy]

Cutter will change the dimensions of the cells when Clipping does not..
Assuming you work with polydata you should check
vtkClipPolyData<http://www.vtk.org/doc/nightly/html/classvtkClipPolyData.html>
http://www.vtk.org/doc/nightly/html/classvtkClipPolyData.html
It is important to remember that in VTK you are always dealing with 3d data
so you define plans not line as a clipping function.
