3707 * all the old state to guarantee, that the EGL-widget will
3708 * receive its frame callback soon. Otherwise, a forced call
3709 * to eglSwapBuffers may end up blocking, waiting for a frame
3710 * event that will never come, because we will commit the parent
3711 * surface with all new state only after eglSwapBuffers returns.
3713 * This assumes, that:
3714 * 1. When the EGL widget's resize hook is called, it pauses.
3715 * 2. When the EGL widget's redraw hook is called, it forces a
3716 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3717 * In a single threaded application condition 1 is a no-op.
3719 * XXX: This should actually be after the surface_resize() calls,
3720 * but cannot, because then it would commit the incomplete state
3721 * accumulated from the widget resize hooks.
