[HarfBuzz] Unified Shaper

Hi all,

we wanted to continue our discussion on this list IIRC, so I'll just  
make a start.

Owen, I think you forgot the HB_GlyphBuffer* args to the  
hb_glyph_buffer functions.

About documentation: once I get CVS access I would like to add  
comments for all types and functions. Are doxygen style comments ok?  
Do you prefer them in the header files or in the *.c files?

Cheers
/Andreas
