[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #5312 Key cancellation glyph position inconsistent

Adding possible 'workaround' (at least for flats) from Harm in casse someone else needs it.

Hi,

I played a little with 'padding-pairs.
Obviously the execption to add 0.3 padding in
key-signature-interface.cc only applies if 'padding-pairs is unset.

Below is limited to flat-cancellation:

\version "2.19.81"

foo = \override Staff.KeyCancellation.padding-pairs = #(lambda (grob)
(let* ((alteration-alist (ly:grob-property grob 'alteration-alist)))
;; limited to flat-cancellation
(if (every negative? (map cdr alteration-alist))
'((("accidentals.natural" . "accidentals.natural") . 0.2))
'())))

\layout {
\foo
}

<<
{ \key aes \major s1 \key c \major s }
{ \key e \major s1 \key c \major s }
>>

For flat-cancellation:
The result is an even spacing of every natural. I'd call it a slight
improvement, but far from optimal.
The gap between first/second natural feels too wide and between
second/third too tight.
Sharp-cancellation is unchanged.

Nothing else in my black-box.

Cheers,
Harm

Hi everyone,Just noticed a bug in the default placement of the naturals when
key is changed.As you can see, the naturals aren't spaced correctly when
using the bass clef.I tried \Staff.override KeyCancellation.padding = #0.2,
but even with a larger padding, naturals aren't spaced uniformly

e.g

\version "2.19.81"

\new Staff {
      \key cis\major
      s1
      \key ces\major
      s
      \clef bass
      \key ces\major
      s^"problem"
      \key cis\major
      s \bar "|."
}
