[HarfBuzz] Documentation

[Behdad Esfahbod]

Hi,

As you may have noticed I've enabled gtk-doc in the tree now.  Which means, we
get HTML pages of all symbols, but there's no content.  I'll go ahead and add
documentation stubs if I can get the emacs macro for it to work, but we would
need actual content.  Feel free to jump in, it's no small task to document
hundreds of symbols that we have accumulated in the library...

Cheers, and happy long-weekend to those it applies to,
