A library for Penner's easing equations
See http://upshots.org/actionscript/jsas-understanding-easing
var t = 0, // current time (ms, s, frames, ...)
b = 10, // initial value
c = 100, // change in value (final value - initial value)
d = 2 // duration (same units as t)
value = penner.easeOutQuad(t, b, c, d);
