Now the QAbstractAnimations will be cached when running an animation (instead of creating and destroying them everytime the animation runs). The next step is to cache *also* the configuration parameters (as aseigo suggested, by having an event filter to detect changes in the animated widgets and reseting the animation parameters as needed). svn path=/trunk/KDE/kdelibs/; revision=1039531
