    Remove usage of gdk_screen_get_rgb_colormap()
    
    gdk_screen_get_rgb_colormap() has been removed from GTK+; there's
    no longer a special visual that is used for drawing true-color
    images distinct from the system visual. So, we don't need to
    check for it; if the visual isn't the system visual, we just
    fall through to the case where we create a new GdkColormap.
