* more efficient undo/redoKartik K. Agaram2022-06-021-2/+35

* after much struggle, a brute-force undoKartik K. Agaram2022-06-021-0/+78
Incredibly inefficient, but I don't yet know how to efficiently encode undo mutations that can span multiple lines. There seems to be one bug related to creating new drawings; they're not spawning events and undoing past drawing creation has some weird artifacts. Redo seems to consistently work, though.
