Make QOpenGLWidget public QOpenGLWidget is now public. In addition Qt::WA_AlwaysStackOnTop is introduced to support the special case of semi-transparent QOpenGLWidget or QQuickWidget on top of regular widgets. hellogl_es2 becomes the qopenglwidget example. This example performs painting both via QPainter and native GL commands and has the OpenGL widget combined with other, normal widgets. The widget stack receives some changes when it comes to renderToTexture widgets like QQuickWidget and QOpenGLWidget. Calling update() will now result in a paint event, which is essential for QOpenGLWidget since we want it to behave like a regular widget. The dirty region handling is extended specially for such widgets due to performance reasons. (an OpenGL content update must not result in any backingstore painting, and is thus handled as a different kind of dirtiness) [ChangeLog] Added QOpenGLWidget. This widget serves as a replacement for QGLWidget.
