Disclaimer: I haven't tried this and I know some things won't work but
....
As a matter of fact, the BalloonCanvas should be able to help you with
that. I used to be able to draw pretty much everything with a
(rotated, scaled whatever) balloon canvas. Some things were not
complete though; most notably dealing with text. So you might want to
give it a try by simply converting your regular canvas into a balloon
canvas and see what you get.
