Gtk.Window.prototype.set_skip_pager_hint

function set_skip_pager_hint(setting:Boolean):void {
    // Gjs wrapper for gtk_window_set_skip_pager_hint()
}

Windows may set a hint asking the desktop environment not to display the window in the pager. This function sets this hint. (A "pager" is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.)
