Re: [csswg-drafts] [css-easing-2] Complex easing/timing functions (#229)

> But if we adopt something like the cubic spline syntax, the main question is can a tool like Greensock implement an algorithm to convert (with a reasonable degree of fidelity) their fixed-up path into the standard notation.

Apparently this isn't a requirement for Greensock. I chatted with the Greensock author about this today, and the way he explained it was instead of generating CSS and delegating to the browser, Greensock always drives animations from JavaScript.

Greensock has its own internal representation for easings that's optimized for efficiency vs perfect accuracy, and it always converts everything (CSS-style easings, SVG path easings, etc) to that internal representation before animating.
