[whatwg] Using SVG instead of Canvas for extensions

The same origin issues with <img src="doc.svg" /> have a mixed history.
I agree that bit-level rendering in Canvas is impractical for most uses.

I've done a bit of work on authoring tools; I would like to see the same 
origin issues with basic SVG references fixed in the near future.
