Good point, actually.
Question: the value ...
\override Staff.TextScript #'self-alignment-X = #center
\c'4^\markup {foo}
... centers the markup *relative to the left note-edge* (or possibly
NoteColumn??), while the combination ...
\override Staff.TextScript #'self-alignment-X = #center
\override Staff.TextScript #'extra-offset = #'(1.0 . 0.0)
\c'4^\markup {foo}
... seems to center the markup *relative to the notecenter* (probably
because 1 horizontal space in the cons passed to extra-offset pretty
nearly equals half the width of a notehead??).
So the question is: is the pair of self-alignment and extra-offset (in
the second example) the best way to center markup relative to
*notecenter* or is there a way to specify the
position-from-which-relative-measures-are-made (like extra-offset)
directly, possibly by referencing the parent grob?
