[GtkGLExt] Drawing Each Frame

[flood <subflood gmail com>]

Hello, I'm making a particle system using gtkglext but I have ran into
a problem. Whenever I run my program it only updates the scene when the
window is not in focus. Meaning once a few particles are drawn it stops
updating the window. I have click on another window and drag it and
only than do I see the scene being updated. 

My setup is simple:

    /* Initialize, Resize, and Render */
      g_signal_connect_after (G_OBJECT (gtkinit->drawing_area), "realize",
                           
G_CALLBACK (InitGL), NULL);
           
           
    
    g_signal_connect (G_OBJECT (gtkinit->drawing_area), "configure_event",
       
             
G_CALLBACK (ResizeWin), NULL);
           
           
    
    g_signal_connect (G_OBJECT (gtkinit->drawing_area), "expose_event",
       
             
G_CALLBACK (DrawScene), NULL);



    /* Show the Program */
    gtk_container_add(GTK_CONTAINER(winInit.window), winInit.drawing_area);
    gtk_widget_show (winInit.drawing_area);
    gtk_widget_show (winInit.window);
    
    gtk_main();


During expose_event I call two functions which update the particles.
