 Multiple people who have experimented with this independently (me,
 Fabian Giesen,and Maxim Shemanarev of Anti-Grain Geometry) have all
 concluded that correct gamma-correction does not produce the best

+gamma correction (or possibly with some arbitrary power stuck in
 there, but it's not really correcting for gamma at that point). Maybe
 this is in part a product of how we're used to fonts being on screens
 which has changed how we expect them to look (e.g. perhaps hinting
 oversharpens them and prevents the real-world thinning you'd see in
 a black-on-white text).

 Nevertheless, even if you turn on gamma-correction, you will find that
 oversampling still helps in many cases for small fonts.
