Try making it compatible with QOpenGLContext::functions() which returns an already initialized QOpenGLFunctions. Unfortunately we cannot make them 100% compatible because functions() conveniently requires that the context (or a sharing context) is current. versionFunctions() has no such requirement and we cannot safely introduce it anymore. What we can do is to state that as long as the context is the current one, the initializeOpenGLFunctions() call can be omitted. If another context (or no context) is current, the call will still be needed, like it is today. Also, we require that the exact same context is current. Sharing does not count since the exact behavior of sharing contexts with different versions is unknown. [ChangeLog][QtGui] initializeOpenGLFunctions() no longer needs to be called when querying a versioned function wrapper object via QOpenGLContext::versionFunctions().
