I just tested this out, and it seems like it does work (that is, draw() IS getting called after a zoom). And, it doesn't seem to be hogging on system resources, calling draw repeatedly. So all in all, I'd say it's a workable workaround, though a cleaner interface in the API would be more convenient.
Thanks!
