  Animations are used for some state transitions on specific widgets.

  Only one running animation can exist for a widget at any specific
  time.  Animations can be added through
  QWindowsVistaStylePrivate::startAnimation(Animation *) and any
  existing animation on a widget can be retrieved with
  QWindowsVistaStylePrivate::widgetAnimation(Widget *).

  Once an animation has been started,
  QWindowsVistaStylePrivate::timerEvent(QTimerEvent *) will
  continuously call update() on the widget until it is stopped,
  meaning that drawPrimitive will be called many times until the
  transition has completed. During this time, the result will be
  retrieved by the Animation::paint(...) function and not by the style
  itself.

  To determine if a transition should occur, the style needs to know
  the previous state of the widget as well as the current one. This is
  solved by updating dynamic properties on the widget every time the
  function is called.

  Transitions interrupting existing transitions should always be
  smooth, so whenever a hover-transition is started on a pulsating
  button, it uses the current frame of the pulse-animation as the
  starting image for the hover transition.
