Comment #9 on issue 1713 by [email protected]: Whole note/dotted note
collision in polyphony
http://code.google.com/p/lilypond/issues/detail?id=1713
Have you started yet, Janek ?
I see the problem. The horizontal shifts are scaled with the width of the
down-stem note-head. The shift should, however, be proportional to the
width of the note-head that ends up on the left (because the reference
points for note-heads are on their left). (Better still to use the sum of
extents between the reference points.)
I see a path to fix this and issue 1546, and issue 53 (which has become
re-broken).
