Re: [csswg-drafts] [css-backgrounds-3][css-borders-4] The shape of box-shadow should be a circle for a box with border-radius:50% and big spread (#7103)

And for comparison, the current spec would be:

```js
function adjusted_radius(radius_width, radius_height, edge_width, edge_height, spread) {
  return [radius_width, radius_height].map(value => {
     if (value >= spread)
       return value + spread;
  
    let r = 1 - value / spread;
    return value + spread * (1 - r**3);
  });
}
```
