3684 * receive its frame callback soon. Otherwise, a forced call
3685 * to eglSwapBuffers may end up blocking, waiting for a frame
3686 * event that will never come, because we will commit the parent
3687 * surface with all new state only after eglSwapBuffers returns.
3689 * This assumes, that:
3690 * 1. When the EGL widget's resize hook is called, it pauses.
3691 * 2. When the EGL widget's redraw hook is called, it forces a
3692 * repaint and a call to eglSwapBuffers(), and maybe resumes.
3693 * In a single threaded application condition 1 is a no-op.
3695 * XXX: This should actually be after the surface_resize() calls,

3697 * accumulated from the widget resize hooks.
