please commit these changes with two separate commits: one for the new class, one for the changes to the rotation animation.

also, we need a way to get to our pre-defined easing curves with a new factory method in Animator, just as we have for animations.


trunk/KDE/kdelibs/plasma/animations/pendulumcurve.h

    the class should not be exported.

> The Plasma::PendulumCurve class subclasses from Qt's QEasingCurve and implements a static function which simulates a "pendulum" effect by varying the progress value from 0 to 1, 1 to 0, 0 to -1 and -1 to 0 in a linear way.
