Hmm, "make check" is running right now, so it may reveal any
problems.

Anyway, everything outside the clipping area (be it a mask or not)
won't ever have any effect. It's like drawing outside of your
monitor...

The only thing that makes me suspicious now are the calls to
begin_mask / end_mask. A mask outside the screen will result into a
NULL mask (hide everything) but will the renderer understand that a
mask is active at all?

I've made a quick test with AGG and it seems fine.

Did you get any results you can tell me?
