QPixmap should be usable from a secondary thread when safe

      Trying to paint a QPixmap from a thread other than the main fails with error "QPixmap: It is not safe to use pixmaps outside the GUI thread" even when the usage is perfectly safe (rendering to a QImage for example).

      This is blocking threaded WebKit rendering (http://bugreports.qt.nokia.com/browse/QTWEBKIT-19). The only alternative would be to change all QPixmaps in QtWebKit to QImages.
