Hi Arjen (on list reply to your comment): I originally thought polygons with the same orientation (see http://en.wikipedia.org/wiki/Curve_orientation) would not simplify the logic, but I was incorrect so thanks very much for this idea which I have just implemented (revision 10727). That and other fixes mean that pages 1 and 2 of example 25 now render correctly with -DFILL_INTERSECTION_POLYGON=ON. There are additional -DFILL_INTERSECTION_POLYGON=ON issues for page 3 and above of example 25, but I feel I am finally beginning to get close to the end of this mini-project.
