Re: [csswg-drafts] [CSS3] Border width rounding clarification

And note that I think we've discussed in the past in the working group that some things (e.g., borders, column rules, line-heights, line grid sizes) should probably be handled differently from the rest, as in the message of mine that [John Resig quoted](https://johnresig.com/blog/sub-pixel-problems-in-css/).  In particular, those should be snapped to *device pixels* at used value time (breaking the constraint that 4 * 25% matches 100%), before their use in layout, whereas we should otherwise do layout using subpixel sizes and snap *edges* at the end (breaking the constraint that every 25% size is the same).

I think there may even have been some implementation convergence towards this model over the past few years, although I'm not sure how interoperable things are.
