Ok, should be ready to go now!

Thanks, this looks kinda acceptable now, from a font rendering POV :)

Is it expected that there is less/worse font hinting with dwrite? Is there a way to switch it back at runtime?

I see it also in Windows itself, so it wouldn't surprise me, for example in the file explorer everything has font hinting except the "home" view which is blurry, or the Windows settings app is also blurry while the old Control Panel has nice hinting.

hm, it's worse with gtk4. I let you decide :)

Even if font rendering is slightly degraded (which may always be improved in later Cairo versions), this new release fixes rendering Emojis, which wouldn't render at all before.
