Ingmar's patch

This (i.e. Ingmar's) patch has been reviewed and deemed incomplete.

Two possible solutions were suggested:
 - the simple way to fix the bug would be to make sure that
   the top-left corner of the surface are (0,0)

- the best way to fix it would be to handle arbitrary extents
   for surfaces, which is presumably needed for handling unlimited
   surfaces (cairo has some support for them, but a lot of places
   still assume that surfaces are bounded and have (0,0) as
   top-left corner).

FTR, I believe that https://bugs.freedesktop.org/show_bug.cgi?id=37140
might be related, or even the same bug.
