Well, I went and looked it up a bit, and it may support non-integer scaling, but it's still fairly coarse: it goes in 25% increments. Text scaling can be done pretty much as fine as you like (the GNOME and Firefox text scaling factors will accept pretty much any decimal you put in). It's only the hidpi-type scaling that is integer-only on GNOME.

I don't recall that...do you have any specific references? At the time hidpi was first added to GNOME, IIRC, only OS X was really doing it, and it only did it in integers (because, as you say, they just make sure that's all the hardware they ship needs). Still, now I got curious and looked it up, it's a bit difficult to interpret Windows' history here. I can at least tell that Windows 7 and 8 had 100%, 125% and 150% scaling settings, and 8.1 and 10 have up to 200% and per-display scaling, but I haven't found any references as to exactly how this is implemented for each release - whether it's really interface scaling, complete with high-resolution interface assets in the OS so the scaled display actually looks sharp, or if it's just text scaling like GNOME's 'text scaling factor'... -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
