I think some time ago this was explained as a NOTABUG in freetype,
which actually obeys the font's preferences and if the font supplies
special images for smaller font sizes, it uses them WITHOUT aliasing
them, which seems logical. Windows seems to lazily alias everything.
If you can find a way to disable embedded bitmaps it might help. The
