[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

Issue 5303 - Misplaced Notehead

In loop calculating the attachments
of chord node heads to stem, calculate
last used position by rounding to int
rather than by truncating to int.

Maintain float precision during calculation
of attachment of noteheads to chord
(thus completing the transition from
int-calculations to floats introduced
in e7cb72c9fce).

Add regression test.

Reported by Éric Bellocq:

\version "2.19.80"

\score {
  { <d' f' a'>2 \clef bass <f, a, c> }
  \layout {
    #(layout-set-staff-size 19)
  }
}

This is a regression against 2.18.2.
The problem doesn’t seem to occur on other staff-positions, if set-global-staff-size is used instead, or at other staff sizes.
