Stores a list of times from 0 to 1 (the elapsed fraction of an animation
cycle) that are used in calculating interpolated
values for PropertySetter given a matching set of KeyValues and
Interpolators for those time intervals. In the simplest case, a
KeyFrame will consist of just two times in KeyTimes: 0 and 1.
Creates a new instance of KeyTimes. Times should be in increasing
order and should all be in the range [0,1], with the first value
being zero and the last being 1
Throws:
IllegalArgumentException - Time values must be ordered in
increasing value, the first value must be 0 and the last value
must be 1
