2 seems rather trivial. Note that rotation about (x,y) is the same as subtracting (x,y), rotating about (0,0), and then adding (x,y). So it should be easy enough, given the rotation of one element, to make another rotate in a shifted coordinate system. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
