3679 * all the old state to guarantee, that the EGL-widget will
3680 * receive its frame callback soon. Otherwise, a forced call
3681 * to eglSwapBuffers may end up blocking, waiting for a frame
3682 * event that will never come, because we will commit the parent
3683 * surface with all new state only after eglSwapBuffers returns.
3685 * This assumes, that:
3686 * 1. When the EGL widget's resize hook is called, it pauses.
3687 * 2. When the EGL widget's redraw hook is called, it forces a
3688 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3689 * In a single threaded application condition 1 is a no-op.

3693 * accumulated from the widget resize hooks.
