Sören,

	I'd say that this should be fairly easy to copy/paste/modify the class 
vtkQuadraticQuad. As internally we are already using the center point 
you are trying to add. I have seen other people from vtkusers mailing 
list have attempted this solution.

	As for your second question about the fact that TessellatorFilter is 
marked as Temp is because we are working on a more generic approach than 
this filter. You'll find more information in VTK, especially in the 
VTK/GenericFiltering subdir.
