Robert Penner elastic easing should give an F-Curve that looks like the easing icon, but it results in an extreme 10-ish transition without elastic effect.

The solution is to set an amplitude and a period, doh!

The amplitude has a default of 0.0, but should be 1.0 IMO.

The behavior of the period property is probably mathematically correct, but it's odd from a user POV I think... It's ok for 0.0, but increasing as well as decreasing makes it go crazy, and I need to crank it up to at least 40 to get sensible results. I expected it to start with soft and few "bounces", and become wilder with more bounces on higher values.
