The algorithms depend on intersections and render /fill by a advancing scan line. FOR Clipper even within a scan beam the rendering proceeds with a scan line provided by the y coordinates of edge - edge intersection points,
Where is this assertion tested and how is it reported back to the callee? I am curious only for odd-even fills of closed input polygons.
