Since it's already allowed in a more limited way, letting the dependent variable (progress) to go outside the 0..1 range shouldn't be much of a problem.

For the dependent variable (time), though -- I'd imagined we'd just use the section of the timing function between 0 and 100%, regardless of where the first/final knots are, extrapolating past the end knots with straight lines if necessary.

`animation-timing-function: cubic-spline(0 0 30%, 1 0 66%);`
