+// 1. Find leftmost vertex in polygon (smallest value along x-axis).
+// 2. Find the two edges adjacent to this vertex.
+// 3. Form a test tri by connecting the open side of these two edges.
+// 4. See if any of the vertices in the poly, besides the ones that form the test tri, are inside the
+//    test tri.
+// 5. If there are verts inside, find the 3 leftmost of the inside verts and the test tri verts, form
+//    a new test tri from these verts, and repeat from step 4.  When no verts are inside, continue.
+// 6. Save test tri as a valid triangle.
+// 7. Remove the edges that the test tri and poly share, and add the new edges from the test tri to
+//    the poly to form a new closed poly with the test tri subtracted out.
+//
+// Note: our polygon can contain no more than 255 verts.  Complex polygons can create situations where
+// a vertex has more than 2 adjacent edges, causing step 2 to fail.  This method improves on the resource
+// listed above by not limiting the decomposition to the leftmost side only.  If step 2 fails, the

+// they all fail.  If they all fail, the polygon is too complex to be decomposed with this method.
