/* ================================
 * A Note About Wrapped Animations
 * ================================
 * A few of the effects below implement two different animations per effect, one wrapping
 * animation that performs the visual effect and a &quot;no-op&quot; animation on this Element where
 * no attributes of the element itself actually change. The purpose for this is that the
 * wrapper is required for the effect to work and so it does the actual animation work, but
 * we always animate `this` so that the element's events and callbacks work as expected to
 * the callers of this API.
 * 
 * Because of this, we always want each wrap animation to complete first (we don't want to
 * cut off the visual effect early). To ensure that, we arbitrarily increase the duration of
 * the element's no-op animation, also ensuring that it has a decent minimum value -- on slow
 * systems, too-low durations can cause race conditions between the wrap animation and the
 * element animation being removed out of order. Note that in each wrap's `afteranimate`
 * callback it will explicitly terminate the element animation as soon as the wrap is complete,
 * so there's no real danger in making the duration too long.
 * 
 * This applies to all effects that get wrapped, including slideIn, slideOut, switchOff and frame.
 */
