Carl,
more out of interest then in ways that I could think of helping; I am
interested in the new
tesselation rework.
Is this related to this message of yours, quoting this paper?

The polygon tessellation routine has problems. It appears that the
following paper has the right answers:

Finite Precision Output, Computation Geometry Theory and
Applications, 13(4), 1999.
