patch for QtWebkit2.1 branch

Adding my fix suggestion to QtWebkit2.1 branch. Trunk will need a the patch to be modified and I'm hoping that someone would come up with better solution.
Whole issue is that VGImage of canvas in Graphics memory won't get updated when pixmap is drawn to. Issue comes from QPainter context that we use here doesn't get end() and state is not flushed. VGImage to be created a flag recreate needs to be set. Simplest way (and cheapest) is to call paintEngine() i.e. what the patch does.
