Even that confuses me :-( does it mean the top of the image moving to
the right, or the bottom? Image processing textbooks always have
increasing angles meaning anticlockwise rotation (hope I've got that
the right way around), I'd say that was the safest model.
given your own uncertainty, i think you proved the "don't use the 
numbers" argument.
what about

    GDK_PIXBUF_ROTATE_NONE
    GDK_PIXBUF_ROTATE_CLOCKWISE
    GDK_PIXBUF_ROTATE_UPSIDEDOWN
    GDK_PIXBUF_ROTATE_COUNTERCLOCKWISE

?
