// From: https://drafts.csswg.org/css-backgrounds-3/#corner-shaping
// ... in order to create a sharper corner when the border radius is small (and
// thus ensure continuity between round and sharp corners), when the border
// radius is less than the margin, the margin is multiplied by the proportion
// 1 + (r-1)^3, where r is the ratio of the border radius to the margin, in
// calculating the corner radii of the margin box shape.
// And https://drafts.csswg.org/css-backgrounds-3/#shadow-shape:
// ... For example, if the border radius is 10px and the spread distance is
// 20px (r = .5), the corner radius of the shadow shape will be
// 10px + 20px × (1 + (.5 - 1)^3) = 27.5px rather than 30px. This adjustment
// is applied independently to the radii in each dimension.
