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
