Thanks much for that example, Behdad!

I'm really late in posting this, but better late than never, right?

	http://cairographics.org/FAQ/#using_pango

The FAQ was already using C, so I ported the example code from python to
C. That definitely made it a little less pretty. And it's possible that
my port could be improved, (it wasn't obvious to me from the pango
documentation whether the C API provides an equivalent of "serif 32px"
or not, for example).

Anyway, Behdad, (or anyone else), if you could read over what I put
together and clean it up as necessary, that would be appreciated.

But this should make a nice addition to the FAQ I think.
