Just added xft support for xmenu and had a bad time doing it.

There is no documentation for xft functions and the only manpage that exists (Xft(3)) only has a fast introduction to some of the most used function calls, but not all of them. If it weren't for dmenu's code I'd not know how to use some functions. dmenu source code has really saved me.

Do some of you know a good resource where I can learn more about xft since there is no official manpage nor documentation? Not even the header file has a comment to explain what a function does or what its arguments mean.
