AtlasEngine: Better builtin glyphs

[lhecker]

This slightly modifies the builtin glyph width and corner radius to
more closely match Cascadia Mono. Previously, at low DPI (100% scale),
the corner radius was barely noticeable which looked kind of bad.

(Ignore the different brightness in the middle. That's just a different theme.)

200% scale

That looks real nice 😃

But i suspect a lot of the same people who complained about aliasing probably wont like this change..
So those control options would be even more needed, at least i added an issue for it!

I'm OK with this - and in the future if the parameters become adjustable that's OK too!

Hey @lhecker, how does it look at 100% scale using a UI like, say, Far Manager or MC? I am worried about the very thick lines, but maybe that is not a necessary concern...

So, I'll be that guy again 😅 – is there any option to turn this off? The double-lined box was more subtle, which I liked more than the current thick line.

The lack of pixels on low DPI displays makes this a very difficult choice. The difference between very thin and too fat is literally just 1px. The ideal solution is for Microsoft to mandate OEMs sell high DPI displays 5-10 years ago. If you think about it, especially when looking at what Apple sells at scale for almost the same price, it's honestly a complete rip-off. (And it affects me too...)

In any case, I tested it on an 1440p display I own, and I personally found the thicker lines to be easier to read, even if I found them to be significantly less "stylish". Because of that I went with this approach in the end. We'll see if there's a lot of people that will complain about this. If there are too many, I'll revert it. The issue to follow to make this a setting is #18180. It's not a difficult change to make and help with it is wanted, because I probably won't get to it within the next few months.
