/* 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. */
