Make QQuickRenderControl public QQuickRenderControl allows rendering Qt Quick 2 scenes into framebuffer objects which can then be used in arbitrary ways in Qt-based or 3rd party OpenGL renderers.

#include <QGuiApplication>
Modernize the rendercontrol_opengl example Make it work when using QRhi-on-OpenGL. Some features like demonstrating a dedicated render thread, or targeting the window with the Quick content ('onscreen' argument, not clear why that was added in the first place), are now removed. Some of these could be reintroduced in future examples, not necessarily in combination with OpenGL. For now they are removed since the cost of porting and maintaining all that is not reasonable at this point.

#include <QQuickWindow>
Support threading with QQuickRenderControl Reorganize the rendercontrol example to demonstrate both the single and multi threaded approaches. A small helper function is introduced to the QQuickRenderControl API: The QSGRenderContext has to live on the render thread. Previously there was no way for applications to move it to the desired thread. This is now possible. Pass --threaded to the rendercontrol example to use a separate render thread. [ChangeLog][QtQuick] QQuickRenderControl can now be used to render the Qt Quick scene on a dedicated render thread, similarly to how the built-in threaded render loop operates.
