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

It's probably worth observing that _motion_ curves (as opposed to 
_timing_/easing curves) in animation software are a little bit of a 
different story. There you're more likely to find NURBS or other more 
sophisticated types of curves which require a bit more work to 
approximate with cubic segments.

On the 1d versus 2d issue -- From what I can see so far, After Effects
 uses one-dimensional piecewise functions for timing curves, although 
I don't have a copy to play with directly. However, poking at the 
implementation of Blender, it appears Blender f-curve segments do work
 similarly to `cubic-bezier()`, using (suitably constrained) 2d bezier
 curves to define the 1d function.
