    Promote "cheese_widget_get_camera" to a public method
    
    It is very convenient for a libcheese client implementing their own
    camera widget to access cheese_widget_get_camera ().
    
    This way a simple camera app could be as simple as:
    
    static void
    on_photo_taken_cb (GtkWidget *cheese_widget,
                       GdkEvent  *event,
                       gpointer   user_data)
    {
        GObject *camera = cheese_widget_get_camera (CHEESE_WIDGET (cheese_widget));
    
        cheese_camera_take_photo (CHEESE_CAMERA (camera), "/tmp/photo");
    }
    
    int main (int argc, char *argv[])
    {
        GtkWidget *window, *cheese_widget;
    
        cheese_gtk_init (NULL, NULL);
        gtk_init (&argc, &argv);
    
        window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
        g_signal_connect (G_OBJECT (window), "destroy",
                          G_CALLBACK (gtk_main_quit), NULL);
    
        cheese_widget = cheese_widget_new ();
        g_signal_connect (G_OBJECT (cheese_widget), "button-press-event",
                          G_CALLBACK (on_photo_taken_cb), NULL);
    
        gtk_container_add (GTK_CONTAINER (window), cheese_widget);
        gtk_widget_show_all (window);
        gtk_main ();
    
        return 0;
    }
