Actually, I spliced three graphs together so the output length follows the red
line simply using #if( ) statements (yes, I know a switch staement would be
much easier).  The graph shows the length between the hip and ankle points on
the x-axis and the adjusted length of the limb on the y-axis.

The equation for the parabola is just:
y =  maximum length  - 1/4  *  1 / cushion  * ( x  -  cushion  -  maximum
length ) ^ 2

This allowed me to set a specific zone where the limb would resist full
extension.  It works pretty well based on my experiments.  In one example I
tried, I just bounced the hip point straight up and down and the legs followed
the jump without snapping at all.
