Wandering Letters word-wrapping

This paper from the Viewpoint Research Institute describes an interesting set of rules for making a text editor: http://www.vpri.org/pdf/m2010002_lobjects.pdf

I've long been a fan of the coding train and Some text formatting/typography stuff would be really great. It's something that we all take for granted but is much more complicated than it seems on the surface.

The first few rules in that paper describe word-wrapping text. It treats the characters almost as particles in their own right, they 'want' to be in paragraphs and so arrange themselves that way. It's fun to think about that.

I made a video of making this text-wrap algorithm work in p5.js, but at the time I didn't have the full paper. https://www.youtube.com/watch?v=A5B-Ro7ff2o

My sketch is here, but I'd really like to see a coding train treatment: https://editor.p5js.org/techbelly/sketches/Xzy4oNwtY
