I'll invite to have a look at the auto-hinter implementation, probably coming up with a patch!
Ok, so I'm still trying to wrap my head around FT's internals and how it all works (anybody got some recommendations on how to explore an unknown codebase and getting a feeling for it?) and stumbled over this: ftview exposes different AA methods and they result in different metrics when using the autohinter? Look at some font with "ftview 16 something.otf", use the autohinter with f and press A, B, C and look at how the glyphs shift around. Shouldn't they stay in place? Interestingly, when Adobe's hinter is active with .otf fonts and you press B (-> autohinter), glyphs don't shift.
Regards, Nikolaus
