Itʼs done that way because thatʼs the way it works, not because of any
decision on my part. When scaling is in use, a screen that has eg
1920x1080 "physical pixels" is presented to us as being 960x540
"virtual pixels". Since Emacs uses physical pixels internally, we need
to divide all the numbers by 2.
