The loss of accuracy should not affect 'normal' users with terrains that are roughly square (say up to 100:1 aspect ratio) and where the Z range is comparable to the X-Y range. Retested with Pauls data, amalric's strange polygon constraint and the standard test constraints. I also added 2 tests for routines with a NULL argument passed to them (no-one would usually pass a NULL pointer to these routines unless - as I did in testing- you remove some of the constraints but still pass their pointer to the routine). And I removed 3 tests for triangles which are already removed when generating the geometry. NB Paul - the previous delaunay triangulator fails under VS8 IF it has any constraints as it attempts to use some vertices that have already been deleted when applying the constraints to edges. Under VS6 and less rigorous compilers it works as the deleted vertices are still in the points stl::Vector; however any added vertices would replace one of the supertriangle vertices with non-disastrous but wrong results." Note, merged with latest name changes in CVS.
