Hi!

I would like to wait for vertical retrace in an X application.  How
can I do that?

The point would be to avoid flicker in my app by using double
buffering and update the on-screen image during vertical retrace.

I've been trying to Google this without any luck so far.  Help!

  Regards //Johan
