Thanks.

I don't use Fontconfig and Cairo, so someone else who does will need
to review the patch and try it.  Would you please post a procedure to
test this patch once applied?

Also, I wonder if this will have any user-level effects, and if so,
should we have a NEWS entry about that?

And finally, to accept changes of this size, we will need you to sign
a copyright-assignment agreement with FSF.  If you are willing to do
that, I will send you the form to fill and the instructions to go with
it.
