Comment for not using QGLWidget would not be necessary why it does exist? For
example, QGraphicsView would not need then QGLWidget viewport then in any case.
My academic guess is that there is strong dependence for OpenGL
QPaintDevice/QPaintEngine built into QGLContext. 

For shared context case (i.e. we have QGLWidget viewport), it might be possible
to create just shared QGLContext (haven't got this work in reality though) but
then the implementation would require either instance of QGLWidget or
QGLContext and I think that is uglier than current approach. But anyway, this
goes beyond scope of this bug.
