While fractional scaling is worthwhile and common on other platforms
and coding for fractional scaling is good generality, it probably
doesn't matter on macOS. On macOS, the operating system does whole
screen stretching for fractional scales with applications seeing an
integer scale.

It would be unusual (but possible) for a user to set the
QT_SCALE_FACTOR environment variable before running an app - I'd
personally consider it for using Qt Creator as a debugger since the
many panes are often cluttered so hide the data I'm trying to track.

Perhaps some applications want to control QT_SCALE_FACTOR with a user
preference mechanism.
