hm...in that code, I just add polygons, booleanize, and convert polygon
structure data into int arrays of polygon data.  as I add polygons by
unionizing each polygon and form muti polygon, it gives me overlay problem.
suddenly at one point, it gives "self-intersecting" polygon as the output.
 Pictures show very clearly the case I'm explaining.  You dont have the
pictures..?
