repro case

1. Open attached svgtest.html from SVGtoDataURLBug.zip
-or-
1. In JavaScript, Create a canvas element
2. use drawImage to draw a new Image() from an SVG source
3. call toDataURL() on the canvas

I would expect to get a data URL with png contents of the image.

Safari instead reports:
SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.

SVG images are complicated and we're not smart enough to determine whether it's safe to return the result to JavaScript.  We're conservative and always throw the exception.
