Improve text rendering in light mode (#7290)
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_coverage` or from the UI (bottom of the
image):

## 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 `#000000`
black text:
