Re: 200% website scaling

In Windows 10, the "Make everything bigger" option (scaling) is in the
"Ease of Access" settings, which can be considered an accessibility
feature. 1.4.4 says "...text can be resized *without assistive technology *up
to 200 percent...".

So if your page looks good at 200% zoom in browser and windows scaling is
100% (essentially assistive technology is turned off), then I'd say you're
ok. If you change your scaling (turning assistive technology on), then
while it would be nice to support browser zoom, if it doesn't completely
work, it's not necessarily a 1.4.4 failure.

It might depend what you mean by "not usable". If your page does not
reflow properly, the problem might be reproducible without scaling turned
on, in which case it would be a 1.4.4 problem.
