For some reason every single pixel access must be authorized through CORS. I am not sure if this is in the standard or just shoddy implementation in all browsers. Try it yourself, read pixels in one non-CORSed image, and then in CORSed and wonder what went wrong on the drawing board. Some people bypass it via WebGL.
