Re: [csswg-drafts] [css-variables] point to URL

`var(--pic2)` is probably a valid URL, but `url(var(--pic2))` is 
certainly not a valid `<url-token>` if not parsed as variable. [The 
"consume a url token" 
algorithm](https://drafts.csswg.org/css-syntax-3/#consume-url-token) 
raises a parse error when it sees the first `(`.
