@fantasai I've fixed the broken link (sorry for breaking it in #2688). However, the new image has a white background, unlike the old one which was transparent. It's kind of hard to make the white background transparent since the font is anti aliased.

In the case of 2688 that didn't matter, but here it is a little unsightly on the green background. Do you think that's fine? Should I restore the previous image as well for the purpose of this figure? Something else?

Use the antialiased image as the alpha channel; set a solid color on the color channel(s). Convert to PNG with alpha transparency. Will now display, anti-aliased, on any background.
