But that's a choice made by the user, knowingly or not. Most CRT monitors
existing today have an aspect ratio 4/3. Squares drawn on the screen with
resolutions like 1280x1024 are slightly rectangular in any and all programs
(taking MS Windows as a sample here.) A UA shouldn't try to figure this out
and render a square differently. Also, I don't know if to figure out the
ratio is at all possible in current windows machines.
