There was a problem hiding this comment.
If nothing else it's now a lot easier to understand what's happening and why, nice!!
Tested the looks on low-dpi SDR Windows Firefox: I found the default settings a tad bit too light, empirically a gamma of 0.9 looked a lil bit better to me. But this is starting to get arbitrary so if you think linear looks good I'm very much in favor with sticking with that
Either way I also believe this to be an improvement compared the harsh and fringy looking boundaries of TwoCoverageMinusCoverageSq

This changes how we convert glyph coverage to alpha (and ultimately a color), but only in light mode.
This is a bit of a hack, because it doesn't fix dark-on-light text in dark mode (if you have any), but for the common case this PR is a huge improvement.
You can also tweak this yourself now using
Visuals::text_alpha_from_coverageor from the UI (bottom of the image):Before / After
Black text Before/after
If you think the text above looks too weak, it's only because of the default text color. Here's how it looks like with perfectly
