Introduce (private) QStyleAnimation
QStyleAnimation handles style animations in a generic fashion by
sending StyleAnimationUpdate events back to the animation target
instead of calling QWidget::update() directly. This decouples style
animations from widgets and makes it possible to run style animations
for QQuickItems (ie. the desktop components).
The next step is to add "QObject* QStyleOption::target" and use that
everywhere instead of the widget pointer passed to various QStyle
methods.
