    libview: Remove calls to deprecated functions gdk_threads_{enter,leave}
    
    These weren't needed anyway:
      * ev_timeline_run_frame is referenced from two calls to g_timeout_add.
        The callbacks will be emitted in the main thread.
      * The function does neither call any GTK+ nor GDK function.
    
    "Tested" with an example presentation using transitions.
