[vtkusers] Filling contour with edge visibility on

[Jothy]

Got it Bill!

There is a trick

pipeline is as I uesd before from capCow.tcl but introducin vtkfeatureEdges
after vtkCutter and setting the stripper input from cutter not from
featureEdges.

I am bit confused, does this featureedges modifies the cutter output
 and makes this modified outpur available to cutter->GetOutput()

Seems to be  special type of operation ( or is it a bug!).

Here is the screenshot

I will add an example to wiki.


Thanks,
