19	* An interface for strategies for determining the location of split points on constraint segments.
20	* The location of split points has a large effect on the performance and robustness of enforcing a
21	* constrained Delaunay triangulation. Poorly chosen split points can cause repeated splitting,
22	* especially at narrow constraint angles, since the split point will end up encroaching on the
23	* segment containing the original encroaching point. With detailed knowledge of the geometry of the
24	* constraints, it is sometimes possible to choose better locations for splitting.
