Update of /project/gsharp/cvsroot/gsharp In directory common-lisp.net:/tmp/cvs-serv13437 Modified Files: drawing.lisp Log Message: Fixed the display of multi-staff clusters, at least those that are not part of a beam group. After the change of the coordinate system, `max' and `min' have become ambiguous. I suggest using `top' and `bot' instead.
