Have a look at SUAjax, this is where all magic is happening. The
interesting methods are #setCanvas: and #process. The first method
creates an URL with the assigned rendering callback #process. Also
interesting is #callback:value: that modifies the URL to include
additional callbacks to pass back values from Javascript to Smalltalk
world.
