           Summary: HTML5 canvas's createImageData should raise the

                    arguments are not finite.

According to
http://www.whatwg.org/specs/web-apps/current-work/#pixel-manipulation:

            "If any of the arguments to createImageData() or getImageData() are
             infinite or NaN, or if the createImageData()  method is invoked
with
             only one argument but that argument is null, the method must
instead
             raise a NOT_SUPPORTED_ERR  exception."
