3657 * This hack should be removed, when EGL respects
3658 * eglSwapInterval(0).
3660 * If this window has sub-surfaces, especially a free-running
3661 * EGL-widget, we need to post the parent surface once with
3662 * all the old state to guarantee, that the EGL-widget will
3663 * receive its frame callback soon. Otherwise, a forced call
3664 * to eglSwapBuffers may end up blocking, waiting for a frame
3665 * event that will never come, because we will commit the parent
3666 * surface with all new state only after eglSwapBuffers returns.
3668 * This assumes, that:
3669 * 1. When the EGL widget's resize hook is called, it pauses.
3670 * 2. When the EGL widget's redraw hook is called, it forces a
3671 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3672 * In a single threaded application condition 1 is a no-op.
3674 * XXX: This should actually be after the surface_resize() calls,
3675 * but cannot, because then it would commit the incomplete state
3676 * accumulated from the widget resize hooks.
