Status of HiDPI support

[Filippo Valsorda]

While trying to figure out why register fonts looked so bad on macOS, I
found a thread from 2013.

The situation definitely improved since, as the only low-res fonts left
are the ones in the register.

That made me wonder if it could be possible to fix those as well,
similarly to how the rest of the UI responds well to
NSHighResolutionCapable, as it would vastly improve readability.

Thank you!
