[vtkusers] Wireframe+vtkPolyDataMapper2D

[David Cash]

Hello,
I am looking to overlay a wireframe or points version of a vtkPolyData
object onto an image being displayed by vtkImageViewer. I tried using
vtkPolyDataMapper2D and vtkActor2D, but the vtkProperty2D doesn't have a
way of changing the representation to wireframe.
Is there a way of doing this without specifically setting up my polydata
to have only lines and vertex cells?
Thanks,
David M. Cash
