Re: [csswg-drafts] [css-images-4] Color stop fixup: do interpolation hints function as positioned color stops? (#3931)

It is quite unfortunate that this is the behavior we have to settle on, but it's also not realistic to change it at this point. A lesson for everyone about what happens when we underspecify things, lol.

No edits have happened after the May 2019 resolution and from a quick look, the spec still seems to imply that hints do not behave like a regular color stop in a couple places, e.g. here (bold mine): 

> Note: The [transition hint](https://drafts.csswg.org/css-images-4/#color-transition-hint) specifies where the “halfway color”—​the 50% blend between the colors of the two surrounding color stops—​should be placed. **When the hint is exactly halfway between the two surrounding color stops, the above interpolation algorithm happens to produce the ordinary linear interpolation.** If the hint is placed anywhere else, it produces a smooth exponential curve between the surrounding color stops, with the “halfway color” occurring exactly where the hint specifies.
