Writing a TrueType font renderer

Hi HN, happy new year!

TrueType is really a neat and fun format, packed with esoterica. This post gives some background on the problem of text rendering in general, explains how TrueType works under the hood, and contains lots of tidbits that I hope will be interesting.

There’s also a bunch of screenshots of the in-progress renderer stumbling over itself. I hope you enjoy the read!
