312 * Animations are used for some state transitions on specific widgets.
313 *
314 * Only one running animation can exist for a widget at any specific time.
315 * Animations can be added through QWindowsVistaStylePrivate::startAnimation(Animation *)
316 * and any existing animation on a widget can be retrieved with
317 * QWindowsVistaStylePrivate::widgetAnimation(Widget *).
318 *
319 * Once an animation has been started, QWindowsVistaStylePrivate::timerEvent(QTimerEvent *)
320 * will continuously call update() on the widget until it is stopped, meaning that drawPrimitive
321 * will be called many times until the transition has completed. During this time, the result
322 * will be retrieved by the Animation::paint(...) function and not by the style itself.
323 *
324 * To determine if a transition should occur, the style needs to know the previous state of the
325 * widget as well as the current one. This is solved by updating dynamic properties on the widget
326 * every time the function is called.
327 *
328 * Transitions interrupting existing transitions should always be smooth, so whenever a hover-transition
329 * is started on a pulsating button, it uses the current frame of the pulse-animation as the
330 * starting image for the hover transition.
