Cheat. Put a new point of slightly different height in the middle of the triangle to form three new triangles that don't have this problem. :)

    Not so fast. All that would do is create a local closed loop that still doesn't cross the boundary:

    ----------------------------------------------------
 \---____                                  ____---/
   \     ----_***********************__----     /
     \         * ----____  ____----*          /
       \         *       +       *          /
         \         *     |     *          /
           \         *   |   *          /
             \         * | *          /
               \         *          /
                 \       |        /
                   \     |      /
                     \   |    /
                       \ |  /
                         \/

      So fudge a corner point by a little.

        And be sure to fudge it in the direction of the points of the other triangles it is a part of.,
