The example code utilizes 64bit integer, but it does not support 64bit integer actually.
For instance, slope comparison is done with multiplication of two coordinate delta and therefore, one if each coordinate value exceeds 32bit range, it causes overflow.
Original Clipper utilizes 128bit integer operation to compare slope.
