We realized that getting the OpenGL paint engine to render widgets was 
not going to succeed, in part due to rendering quality issues (less 
perfect antialiasing, incorrect line / polygon rasterization), and in 
part due to performance (the imperative QPainter API _is_ more ideal for 
a software based paint engine than an OpenGL based one).

So the OpenGL based window surface that we experimented with in Qt 4 has 
gone away. The Qt Quick 2 scene graph is the way of getting the best 
performance out of OpenGL.
