It seems you got the "normalization" thing by now :)

I had the normalization step in mind while doing the DrawingAPI interface
so we have a ::finalize method in DynamicShape which should be called before
any function that needs normalization of it (rendering, hit test, bounds
computation) and that uses a "dirty" flag set whenever something is drawn.
Currently the function does nothing.

Note also that the previous algorithm (ray-crossing) worked for that
case (could still be pure luck). Drawing clockwise and counter-clockwise
was an intentional step, additional drawings in that file would be appreciated
(like the crossing edges one) for future safety net when changing algorithms.
