I have tried to implement the change on my system and have run the
regression tests and: 

YUK! The constrainedDelauney.tcl test fails!

Attached is the image generated. It is clearly not the same as the
reference. Also warnings pop up from vtkDelaunay2:

In function FillPolygons this is triggered:

...
p1 = pts[i];
p2 = pts[(i+1)%npts];
if ( ! this->Mesh->IsEdge(p1,p2) )
{
  vtkWarningMacro(<<"Edge not recovered, polygon fill suspect");
}
...

,which I find quite mysterious! Any ideas?

Regards,
Rasmus
