Made GL2 engine default for QGLWidget, and added GL2 sync() function
To allow mixing QPainter and raw OpenGL commands we need to have some
way for the user to say that's he's about to use raw OpenGL so that we
are free to do buffering optimizations in the paint engines and use
either GL1 or GL2 paint engine. As there's already a syncState()
function in QPaintEngine we've reused this and added
QPaintEngineEx::sync() which takes care of syncing/flushing the paint
engine.
