Description

This feature adds a "progress" property to the JavaScript class Animation.

The goal of this property is provide authors a convenient and consistent representation of how far along an animation has advanced across its iterations, regardless of the nature of its timeline. Without animation.progress, a developer would need to manually compute how far an animation has advanced factoring in the number of iterations of the animation and whether the currentTime of the animation is a percentage of total time (as in the case of scroll-driven animations) or an absolute time quantity (as in the case of time-driven animations).
