Start rewriting the script to split font, so that it could work with various Open Type Math fonts (Asana-Math, Gyre-Pagella, Gyre-Termes, Latin-Modern, Neo-Euler, STIX-Web)
Improve how the fonts are split + add scripts to do the font conversions.
Rewrite copyRange to handle each glyph individually. This makes the processing slower, but allows to ignore empty glyphs.
Merge branch 'open-type-fonts' into stix-web-fonts
Use the new script to split the font from the open-type-font branch.
