You can access the entire FreeType FT_Face object with

	FT_Face XftLockFace (XftFont *font);

Make sure you call

	XftUnlockFace (XftFont *font);

when you''re done poking inside it.

Hello,

Is it possible to access the font glyph data? The only function
I found is XftGlyphExtents, which is undocumented and
XGlyphInfo parameters'' names are uninformative.
I need to read the parameters like subscript/superscript position,
underline position/thickness, inter-line interval etc etc. I am sure
these are present deep down in libfreetype''s guts, but how would I 
access them in a portable way?

I would also appreciate the documentation to Xft, if there is something
more extensive than ''man 3 Xft'' .

Thanks,
   Dmitry Karasik
