Geoff, Robert -- There appears to be a problem with the osgUtil
DelaunayTriangulator in current CVS.
 
At about line 774 in DelaunayTriangulator.cpp, three vertices corresponding
to a "supertriangle" are added to the points list. What I'm seeing with the
current code is that the last one of these vertices appears to be
incorrectly included in the final triangulation (the result triangle mesh
incorrectly extends outside my point domain in positive Y). If I change the
order of these vertices so that the first vertex is last, then my
triangulation incorrectly extends out in negative X. So, whichever vertex is
last seems to mistakenly end up in the triangulation.
 
This is with current CVS v1.12 of this file. If I back out to v1.11, the
problem goes away.
 
Any idea what might be going awry here?
