https://github.com/Pomax/Font.js/blob/ac30a5f2f65c9af46040c1f036319d1a12d7ac8b/src/opentype/tables/common-layout-table.js#L57-L64 references it, but will definitely hit a runtime error if that code ever gets used right now.
It's referred to in the common layout table file, but doesn't actually exist, so... that needs implementing?
