Starting point for the sources: http://akkartik.github.io/mu/html/baremetal/shell/line.mu.html

The architecture is now much cleaner. Functions contain lines, lines contain words, words contain gap buffers. Rendering a thing renders its constituent things. Render takes a top-left coordinate and returns a bottom-right coordinate. Each thing knows which constituent thing has its cursor, shows its cursor when rendering, redirects incoming keystrokes to it.
