Serendipity led me to libschrift, a lightweight TrueType font rendering library, which a candidate to be used for rendering fonts for swift-geometrize.

libschrift refers philosophy

We are the home of quality software such as dwm, dmenu, st and plenty of other tools, with a focus on simplicity, clarity and frugality. Our philosophy is about keeping things simple, minimal and usable. We believe this should become the mainstream philosophy in the IT sector. Unfortunately, the tendency for complex, error-prone and slow software seems to be prevalent in the present-day software industry. We intend to prove the opposite with our software projects.

SwiftTrueTypeFont is one more candidate to explore reading TrueType fonts.
