Re: [csswg-drafts] [css-transitions][css-animations] Complex timing functions

Adding the missing position parameter to the two control values, the 
syntax would be something like `cubic-spline(c, [c, t, p, c,]* c)`. 
And that example becomes:

```
@keyframes {
    from {
        some-property: 100px;
        animation-timing-function: cubic-spline(0.125, 0.4, 0.5,0.5, 
0.75, 0.8);
    }
    to {
        some-property: 50px;
    }
}
```
