This is not related to interpreting bytecode. But does it contain hidden assumptions about how bytecodes are interpreted (by specific renderer, and specific version of now-simplified renderer )? > Well, the Infinality stuff was basically unmaintained; it essentially > consisted of a large bunch of exceptions for some special fonts. > Alexei and I agree that we no longer need this. There was not a > single voice objecting to its removal, by the way... I agree there is no general usage for it. For the purpose of fontval's backend, until a genuine Microsoft backend happens (if ever), I suspect that the infinality stuff behaves closer to Microsoft renderer towards Microsoft hinted fonts. So if the goal is not "good enough hinting" but "matching Microsoft behavior", it has to stay. So FWIW, I am just mentioning that I will carry a reverse diff in future version of Fontval, if another release ever happens...
