// This sample plugin shows how to allow the interpolator to perform its own
// evaluations at the keyframe time locations, allowing the curve to not pass
// through the keyframe values. In this example, the curve is linearly
// interpolated to values halfway between the keyframe values and the keyframe
// values in the neighboring spans.
