Well, the thing is that the renderer interface currently doesn't have a
full definition for complex (self-intersecting) polygons. It works, but
I'm not sure for instance if all current renderer implementations give the
same result.
X for instance has two filling rules for polygon "EvenOddRule" and
"WindingRule" (check the manpage for XSetFillRule). I don't know which is
default. libart uses the winding rule I think...
One should really specify these details before going on.
