To hold an (effectively) infinite *bitmap* canvas, you'd (effectively)
need an (effectively) infinite amount of memory.  However, it could be
done with an (effectively) infinite *vector* canvas.  That way you
could limit the on-screen rendering to just the clipped subset of the
vector collection.

You'd still want to make it easy to toggle between "draw" and "stop
drawing", but you could make a mouse-click.

To implement, just pick a GUI library tkinter, wx, or whatver.
