I saw that hardcoded value and wrote the following code which arrives
at 1.251178 (though that value uses only half the stem's extent).
Haven't tried it with other heads/styles.
#(define ((shift offsets) grob)
(let* ((note-heads (ly:grob-array->list (ly:grob-object grob 'note-heads)))
(stem (ly:grob-object grob 'stem))
(stem-ext (ly:grob-property stem 'X-extent)))
(for-each
(lambda (p q)
(let ((head-ext (interval-length (ly:grob-property p 'X-extent))))
(ly:grob-translate-axis! p (* q (- head-ext (cdr stem-ext))) X)))
note-heads offsets)))
displaceHeads =
#(define-music-function (parser location offsets) (list?)
#{
\once \override NoteColumn #'before-line-breaking = #(shift offsets)
#}
)
