I am experiencing problems with aliasing-disabled rendering, and if
you look at Kaya's screenshot (my system, and any other will
probably do, shows just the same behaviour)
http://kayalabs.com/images/tahoma.png
you will see the difference in rendering Tahoma's 8 and v -- in
freetype's version you have just one more pixel and it's really
disturbing and annoying.
This has been discussed at great length on the freetype-devel list,
IIRC. The `correct' rendering result of Tahoma on Windows is tightly
bound to anomalies in the Windows rendering engine which internally
rounds certain values differently, namely in an undocumented and
unpredictable way. With other words, Windows is `wrong'. The correct
solution is to fix the bytecode instructions for those two characters
-- this breaks the digital signature, but FreeType ignores it anyway.
A longer time ago I announced to provide a patch, but unfortunately I
haven't found enough time yet to do that.
