/* Use a long animation that start at 50% progress where the slope of the
selected timing function is zero. By setting up the animation in this way,
we accommodate lengthy delays in running the test without a potential drift
in the animated property value. This is important for avoiding flakes,
especially on debug builds. The screenshots are taken as soon as the
animation is ready, thus the long animation duration has no bearing on
the actual duration of the test. */

// The start delay of the animation makes it jump 50% of the animation, which
// means we would select the keyframes at 10% and 100% for animation. The
// progress would be (0.5-0.1) / (1-0.1) = 0.44. So a timing function input of
// 0.44 results in an output of 0.5.
