Comment 32 for bug 1687246

For my 15" display with 3840*2160, without the workaround I get 100, 200 (too small), 300 (too large), and 400. Is it intentional that with the experimental workaround from the first comment enabled, I have 125, 150, 175 and 200% but nothing above it?
The maximum of 200% is too small and I use a 1.20 font scaling in Tweaks, so I'd be looking for an option to scale by 240%.
