[HarfBuzz] Documentation?

[Sebastien Metrot]

Hi,

I would like to use harfbuzz to handle the glyph layouts in my GUI 
toolkit (I already use freetype2 for the glyph rendering). I looked at 
the test code but found it quite undocumented. Is there some doc about 
the API and how to use harfbuzz with freetype2? (I already have a simple 
/naive font layout engine in my toolkit. I would only need to get 
correct glyph indices and rendering coordinates for each glyph).

Thanks in advance,

Sebastien
