* \brief Animates changes fading the new UI over the old look.
*
* This widget will put itself above the widget that will change and show a fading transition from
* the old to the new UI. It will delete itself after the animation is finished.
* Example:
* \code
* KFadeWidgetEffect *animation = new KFadeWidgetEffect(widgetThatWillChange);
* // do changes on widgetThatWillChange
* // ...
* animation->start();
* \endcode
*
* \note The widget that changes needs to have a parent widget. KFadeWidgetEffect does not work
* for toplevel widgets (windows).
