Re: [csswg-drafts] [css-transitions]/[css-animations] Proposal: Allow velocity values for transition-duration and animation-duration (#5091)

But even with just lengths,

```css
#element {
  animation: anim 100px/1s;
}
@keyframes anim {
  from { width: 0px; height: 0px }
  to { width: 100px; height: 200px }
}
```

`width` wants to increase 100px with a speed of 100px/1s, so it wants the animation to last 1s.
`height` wants to increase 200px with a speed of 100px/1s, so it wants the animation to last 2s.

Then, either one of them wins (which one?) or I guess it's converted to something like

```css
#element {
  animation: anim 2s;
}
@keyframes anim {
  0% { width: 0px; height: 0px }
  50% { width: 100px }
  100% { height: 200px }
}
```
