Note: This doesn't support double position color hint syntax yet. This seems like something that should be supporter for all gradients or none, and, since it is just sugar over using two hints, I opted to leave it out of the first change.

One thing I am not sure of is if all the CSS text results in the test case are correct. e.g should "at center" map to "at center center" and should "hsl(0,0%,75%)" map to "rgb(191, 191, 191)"?

Would be nice if these could be WPT proposals in http/wpt/

Nit: space after for

> LayoutTests/fast/gradients/conic-gradient-parsing.html:51
> +        s += "white " + (x/500) + "%, " + ((2 * x + 1) / 1000) + "%, ";

Nit: s += `white ${x/500}%, ${(2 * x + 1) / 1000}%, `;
