------- Additional Comments from Hwang <luxtella at company100.net>
JavaScriptCore treats this by JSCanvasRenderingContext2DCustom.cpp but V8 does
not treats this.

>From HTML5 canvas spec:
http://dev.w3.org/html5/2dcontext/#dom-context-2d-createpattern

"If the first argument isn't an img, canvas, or video element, throws a
TYPE_MISMATCH_ERR exception."

This patch makes Chromium pass
