The new TrueType interpreter in FreeType 2.7.0
"Switching to the new mode might take some getting used to though, so if you think your fonts are suddenly fat, fuzzy or weird, give your brain some time to adjust."This is true, and IMO it's the reason font rendering is much less important than people think. When I got a new pair of glasses I disabled font anti-aliasing to make the edges as sharp as possible. I did this so I could more quickly learn to focus my eyes correctly with the new glasses. By the time I had mastered the glasses I was used to the font rendering, and I have not switched it back. I now prefer fonts with no anti-aliasing. If you'd told me in the past that I'd end up preferring that I might not have believed it.The most legible font is the one you're used to. People can read Blackletter or Spencerian like it's a normal font if they're used to it. I think vector fonts were a mistake. It's a lot of software complexity for very little value.
