/**
* Gets the animated value, given the elapsed fraction of the animation (interpolated by the

* function maps the input fraction to the appropriate keyframe interval and a fraction
* between them and returns the interpolated value. Note that the input fraction may fall
* outside the [0-1] bounds, if the animation's interpolator made that happen (e.g., a
* spring interpolation that might send the fraction past 1.0). We handle this situation by
* just using the two keyframes at the appropriate end when the value is outside those bounds.
