3721 * all the old state to guarantee, that the EGL-widget will
3722 * receive its frame callback soon. Otherwise, a forced call
3723 * to eglSwapBuffers may end up blocking, waiting for a frame
3724 * event that will never come, because we will commit the parent
3725 * surface with all new state only after eglSwapBuffers returns.
3727 * This assumes, that:
3728 * 1. When the EGL widget's resize hook is called, it pauses.
3729 * 2. When the EGL widget's redraw hook is called, it forces a
3730 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3731 * In a single threaded application condition 1 is a no-op.
3733 * XXX: This should actually be after the surface_resize() calls,
3734 * but cannot, because then it would commit the incomplete state
3735 * accumulated from the widget resize hooks.
