New issue 3677 by address@hidden: RehearsalMark breaks system's
ref-point?

it seems that when there is a RehearsalMark, the reference point of a
system changes and the relative extents are calculated in an
unreasonable way.
Here's the background - i got a bug report about \shapeII:

Hi Janek,
This [\shapeII] is a very nice function you have made. But I get
unexpected results
when I use a rehearsal mark.
Please see the included snippet.
I did some tests and here's what i got. I have a function (it's very
lame, i know) that does some bogus override of a slur's "positions"
property, and in the meantime it prints the relative Y-extent of
slur's left NoteColumn:
\version "2.17.96"
foo =
#(define-music-function (parser location item)
(symbol-list-or-music?)
(define (quux grob)
(let* ((orig (ly:grob-original grob))
(bound (ly:spanner-bound grob LEFT))
(ref (ly:grob-system bound)))
;; print the extent of the left NoteColumn relative to the system:
(display (ly:grob-extent bound ref Y))
;; bogus value:
(cons 3 3)))
#{ \tweak positions #quux #item #})
\relative c'' {
\foo Slur
d1( c')
}
In this case it outputs (0.449994 . 1.550006) - as expected: the
extent of the d note, measured relative to middle staffline, is
roughly (0.45 . 1.55) staffspaces.
But when i add a rehearsal mark:
\relative c'' {
\foo Slur
d1( c')
\mark \default
}
the output is (-4.100012 . -3.0), as if the point against which the
extent is measured was on top of the higher note (instead of middle
staff line). Indeed, if i change the higher note to e
\relative c'' {
\foo Slur
d1( e')
\mark \default
}
the extent is further "lowered" by 1 ss: (-5.100012 . -4.0)
This behaviour seems extremely weird to me. Do you know anything about
this?
