Calculate the output of a unit cubic Bézier curve from the two middle control points.
X coordinate is time, Y coordinate is function advancement. The nominal range for both is 0 to 1.
The start and end points are always (0, 0) and (1, 1) so that a transition or animation starts at 0% and ends at 100%.
