new fork: show raw text for drawing below it

https://merveilles.town/@maleza/109398870908062135

Lots of issues:
* can't edit the raw text
* ..but it confusingly displays a second cursor
* raw text doesn't update when drawing (need to constantly deserialize
  the drawing to JSON)
* ... lots of others

This is an early experiment.

-  uses separate shortcuts for regular polygons. `ctrl+3` for triangles,
-  `ctrl+4` for squares, etc.
-* https://codeberg.org/akkartik/text.love -- a stripped down version without
-  drawings; useful starting point for some forks
-* https://git.sr.ht/~akkartik/pensieve.love -- a note-taking app on an
-  infinite 2D surface. Still in development.
-* https://git.sr.ht/~akkartik/capture.love -- a blank-slate mode for the
-  note-taking app, so all the stuff pensieve.love puts on screen doesn't cause
-  you to forget what you came to write down.
