Looks good to me, except the item font here seems a little weird (the lowercase a and e get chopped a bit) - is this just because the outline is the same color as the background?

Wait, I can just try it and see!

Yeah, it looks fine with a non-background color even though the thin letters are still technically chopped up. So I think it's a non-issue for this PR.

[AEFeinstein]

Yeah, I made the decision to draw the outline on this inside edge of the font rather than the outside edge so that the outline font would be the exact same size and could be drawn without any offsets. The downside is that thin fonts don't take it so great.
