Super grob, parent of all:

The columns of a score that form one line. The toplevel grob. Any grob has a Line_of_score as both X and Y reference point. The Paper_score contains one grob of this type. Control enters the Grob dependency calculation from this single Line_of_score object.

before-line-breaking-callback (procedure):

after-line-breaking-callback (procedure):
