Thanks Bert,

this was interesting to know. I looked even deeper into the process of
Squeak drawing and found yet another suspicious place where a sort of
a clipping is setup (see the whole process documented on Mantis).

Patching two places hardcoding clipping limits fixes the issue I
reported. The patches work fine for me, but maybe an expert can look
at the side-effects ;-) I suggest that we included those patches as
soon as possible as it is really a show-stopper for the graphic
capabilities of Squeak.
