This simplifies and further optimizes text-width computation by computing the entire width table in advance, and serializing it in the style of QuickTextMeasurer (#1390). This entirely removes the need for PDFKit at runtime. This has the advantage of fixing #1305 – more generally: producing the same result everywhere – without having to deploy a copy of Verdana. The lifting is delegated to these three libraries, which are housed in a monorepo: https://github.com/metabolize/anafanafo I'd be happy to move it into the badges org if folks want to collaborate on maintaining them. QuickTextMeasurer took kerning pairs into account, whereas this implementation does not. I was thinking kerning would be a necessary refinement, though this seems to work well enough. I dropped in a binary-search package to traverse the data structure, in part to conserve space. This causes a moderate performance regression, though there is ample room for improving on that: https://github.com/badges/shields/pull/2311#issuecomment-439182704
