img.crossOrigin test case

Loading an image URL without img.crossOrigin set dirties a canvas2d context and canvas.toDataURL()
throws a security exception. Attempting to reload the same resource, this time with img.crossOrigin='' set, also fails.
Webkit is caching the image resource and the CORS preflight is never made.

Attached is a test case that hits a Picasa image (which support CORS). The first image will
fail, but the second try (which has img.crossOrigin='' set) SHOULD succeed. In the test case, both FAIL.
Web inspector shows a single request being made.
