An argument could be made about the lesser impotance of stability 
guarantees for the Cairo users (since it's already broken). So I'd ask 
whether the given patch makes it considerably more usable, so that more 
people are likely to try the --with-cairo build and submit patches/bug 
reports/etc.

IIRC, somebody said it's the best approach we have for supporting 
Wayland someday. I think it's a worthy goal.
