[comp.graphics] Triangulating arbitrary planar polygons

I don't have a solution to your problem, but here's a pointer to two papers
that discuss triangulation & shape complexity in great detail

1. Triangulation Simple Polygons & Equivalent Problems - Alain Fournier &
   Delfin Montuno (Univ. of Toronto)

2. Triangulation and Shape Complexity - Bernard Chazelle & Janet Incerpi
   (Brown Univ)

Both papers are published in the ACM's Transactions on Graphics Vol.3 
Number 2 (April 1984)
