12c75e9737
Another progress function from the CSS3 Transitions specification, using a parametrices cubic bezier curve between (0, 0) and (1, 1) with two control points. (sadly, no ASCII art can approximate a cubic bezier, so no graph) The cubic-bezier() progress function comes with a bunch of preset easing modes: ease, ease-in, ease-out, and ease-in-out, that we can map to enumeration values.
