Does TTfautohint allways snap upwards, to the pixel edge above? rather 
than snapping to the pixel edge below, even if the pixel edge below is 
closest? When hinting manually the direction of snapping can be 
controlled, so i'm wondering if it could be controlled by the autohinter 
too. Does freetype do this already?

If i look at manually hinted versus ttfautohinted fonts, at a range of 
sizes, and on GDI cleartype, greyscale, and Directwrite, i can see good 
manual hinting has the edge only on GDI at sizes below say 12pt. If the 
snapping at smaller sizes could be controlled in TTFautohint to get rid 
off "i" becoming "l" in some fonts, then overall i'd say ttfautohint is 
worth all the time saved from manual hinting.
