iOS: Send expose event when a window changes the geometry.
When the EAGLView view changes its layout, it must send the expose event along with the geometry change. It is important to notify the render loop of the scene graph that the windows's geometry has changed. The render loop is waiting for the WM_Expose event and updates the scene's window size accordingly. See QSGRenderThread::event for reference. Without this notification, the geometry of window is updated, but the scene is rendered incorrectly, for example when the orientation of screen changes.
