    known issues:

        - safari can't open multiple iframes properly
        - constrainToViewport: body must have no margin or padding for this to work properly
        - iframe will be mis positioned during fade in
        - document.viewport does not account for scrollbars (this will eventually be fixed in the prototype core)
    notes

 * Do not remove any comments above this line, below comments may be removed to save space.
 *
 * An adaptation of Robert Penner's "easing equations" as seen in many Flash animations for
 * Script.aculo.us 1.8.  One of my great pains in working with Script.aculo.us over other
 * libraries was the lack of these easing equations so I set about to port as many of the
 * equations as I could.
 *
 * Imlements from Penner's equations:
 * 		Quadratic
 * 		Cubic
 * 		Quartic
 * 		Quintic
 * 		Sinusoidal
 *		Exponential
 *		Circular
 * 		Bounce (easeOut only)
 * 		Back
 *
 * Does not implement (yet)
 * 		Elastic
 *		Bounce (easeIn, easeInOut)
 *
 * Ken Snyder provided a few reference implementations of Penner equations for
 * Script.aculo.us; these reference implementations aided my work in porting a
 * (more) complete set.
