[css-backgrounds] Clothoid Corners for border-radius

Some UIs, like the native iOS UI, are cornered using a clothoid curve. I believe that supporting this in CSS will increase expressiveness and interoperability.

.box {
    border-radius: clothoid(3em);
}

This proposal seems to be proposed as a squircle in css-borders.
