Alias for CSS keyframes. Defaults to an animation-
concatenated with an identity counter.
Approximates the key points calculated for the easing function in Complex animations reducing the number of returned keyframes.
Include all prefixes supported by the browser (e.g. for WebKit).
Append a CSS transform clause to each keyframe (useful if you want the target element to have a constant transform applied on top of the animation transforms).
Force the output to include all prefixes, even if the browser doesn't support it (e.g. for WebKit).
