  * Connect vertices so all resulting faces are convex.
+ *
+ * Implementation:
+ *
+ * - triangulate all concave face (tagging convex verts),
+ * - rotate edges (beautify) so edges will connect nearby verts.
+ * - sort long edges (longest first),
+ *   put any edges between 2 convex verts last since they often split convex regions.
+ * - merge the sorted edges as long as they don't create convex ngons.
