idea is that you would get a canvas proxy object, pass it to the worker,
have the worker create a 2D Context, bind the canvas proxy object and the
context, and then a method on the canvas proxy could be used to push the
graphics instructions sent to the 2D context to the screen.
I hope to have a more concrete proposal ASAP.
