Currently, if we changed PangoCairo backends, register_font won't work as expected. And shifting backend is as simple as PANGOCARIO_BACKEND variable to fc, this should work on both Wheels distributed on Windows and macOS. (This isn't a thing on Linux as Fontconfig is the default backend). This can help in testing because rendering would be the same if the font backends are the same.
