[csswg-drafts] [css-backgrounds][css-display][css-box] anchoring terminology for the border box taking corner shape into account.

frivoal has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-backgrounds][css-display][css-box] anchoring terminology for the border box taking corner shape into account. ==
As a baby step towards defining hit testing that would be useful in other places as well, a css spec should define some anchoring terminology for the area encompassed by the border of an element, taking corner shaping (by border-radius and possible future properties) into account.

Quite possibly the term `border edge` is the one I'm after, but it is defined in CSS2.1 without mentioning border-radius, then effectively monkey-patched in [CSS Backgrounds 3 ยง5.1](https://www.w3.org/TR/css3-background/#the-border-radius) to say that it is affected by border radius. That spec should probably provide an updating definition of `border edge` that states explicitly states it takes corner shaping into account(`corner shaping` should probably be an anchor term as well), and then let border-radius state how does the corner shaping.

While we're at it, we should also clarify whether the `border box` takes corner shaping into account. 

This would have been useful at least in in https://drafts.csswg.org/css-ui-3/#cursor, and in https://wicg.github.io/spatial-navigation/#heuristics
