Woah 😮
My favorite pet issue I never got around to fixing: make stem darkening
for the autohinter be as good as the CFF variant. Also, at least basic
stem darkening for bytecode'd TTFs. Then Qt can go all in on stem
darkening and rendering fonts correctly. And hopefully everyone else.
Also, the build system generation thing sounds very meta. I'd prefer
settling on a single build system (either CMake or Meson and nothing
else) 😁
And even a basic testing framework sounds good. One could, if so
inclined, even use https://github.com/rougier/freetype-py and use
pytest and hypothesis to hammer out a test suite.
