[vtkusers] 3D surface to 2D silhouette

[Cory Quammen]

I haven't used this class, but the documentation says that it
generates the edges of the poly data that form the silhouette. Won't
rendering these edges into an image get you where you want, assuming
the vtkPolyDataSilhouette class uses the same vtkCamera as the
renderer?
