Re: [w3c/permissions] A new permission for canvas data (#165)

I read your article. They fingerprint 2d context only by rendering fonts. I see, that Linux does not have "Arial" font, so it uses a font, that is a lot different. I also think, that Mac OS uses Helvetica for rendering Arial.

The rendered font differs only for a each combination of  OS and a version of a browser. But this information can be achieved otherwise, without Canvas. So allowing only page-supplied fonts to be rendered should solve all this.
