Implementation of the
[linear](https://www.w3.org/TR/css-easing-2/#the-linear-easing-function) easing
function, which is now widely supported by all browsers, but still missing in
JavaFX.
It allows developers to approximate arbitrary easing functions with linear
segments:
linear(
/* Start to 1st bounce */
0, 0.063, 0.25, 0.563, 1 36.4%,
/* 1st to 2nd bounce */
0.812, 0.75, 0.813, 1 72.7%,
/* 2nd to 3rd bounce */
0.953, 0.938, 0.953, 1 90.9%,
/* 3rd bounce to end */
0.984, 1 100% 100%
)
