Fixes wrong QPaintEvent::region() in QGLWidget::paintEvent.
QGLWidget does not support partial updates unless the context is single buffered and auto-fill background is disabled. The problem was that QPaintEvent::region() returned the requested update region without taking into account the limitation of QGLWidget. If QGLWidget doesn't support partial updates, it means everything has to be updated, and QPaintEvent::region() must return the whole widget rect. Auto test included.
