Web animation is --to my knowledge-- only for the manipulation of the dom's children element and to some extent the dom itself. What of the canvas? Is there any interest in simplifying or and adding on to the requestAnimationFrame? Like making it a constructor or making Daemon object to better PUI--programmer user interface--?
