Documentation recommends deprecated QGraphicsItemAnimation usage

QGraphicsItemAnimation is deprecated in Qt 4.8.0. However, the documentation for QGraphicsItem::advance() mentions QGraphicsItemAnimation as an alternative to item animation. This is misleading.

Similarly, QGIA is mentioned in Porting to Graphics View (http://developer.qt.nokia.com/doc/qt-4.8/graphicsview-porting.html) in Porting table at Q3Canvas::setAdvancePeriod(). This is also misleading, I think, as it gives a deprecated feature as a porting alternative. The Detailed Description for QTimeLine also mentions QGIA, but I don't have an opinion on this.
