    app: Bail out, not fail, in gimp_view_render_to_surface() buffer test
    
    Don't fail when checking for availability of buffers in
    gimp_view_render_to_surface(). The buffers will be gone when quitting
    GIMP while in s-w-m and we don't want to print a warning every time
    that happens.
