title: how to enable vertical sync in opengl?
body: <p>How do you enable vertical sync?</p>
  
  <p>Is it something simple like <code>glEnable(GL_VSYNC)</code>? (though there's no such thing as GL_VSYNC or anything like it in the options that glEnable accepts).</p>
  
  <p>or is there no standard way to do this in opengl?</p>
