  Yep, you are right -- the doco mentions fl_begin/end_polygon works for CONVEX polygons, and fl_begin/end_complex_polygon works for CONCAVE polygons (also). I apologize for not paying attention to this initially. BTW winding order is addressed in a note for fl_begin/end_complex_polygon, but for fl_begin/end_polygon (convex case), I see no mention of a constraint for CCW vs. CW traversal.
