That would be good. If LibGGI clips wrong, that's an error. 
Though you probably had a bit of an extreme case.

Yes. But please note, that LibGGI (as one of the few graphics libs that do
so) claim to draw _exact_ lines, which is very important for HW support.
So it has to do _exact_ clipping as well.
