3700 * all the old state to guarantee, that the EGL-widget will
3701 * receive its frame callback soon. Otherwise, a forced call
3702 * to eglSwapBuffers may end up blocking, waiting for a frame
3703 * event that will never come, because we will commit the parent
3704 * surface with all new state only after eglSwapBuffers returns.
3706 * This assumes, that:
3707 * 1. When the EGL widget's resize hook is called, it pauses.
3708 * 2. When the EGL widget's redraw hook is called, it forces a
3709 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3710 * In a single threaded application condition 1 is a no-op.
3712 * XXX: This should actually be after the surface_resize() calls,
3713 * but cannot, because then it would commit the incomplete state
3714 * accumulated from the widget resize hooks.
