The way it works right now is useful for cases where you don't want to leave
junk on the canvas when the user is 'done' (either temporarily, or
permanently) with your Magic tool.

Albert's history stuff (see his post) is interesting and likely useful.
Another thing that could help is to tell you, in switchin()/switchout(),
what's going on.
