7-year-old question

[Bric]

In 2005 someone asked this - 
http://lists.gnu.org/archive/html/lilypond-user/2005-11/msg00273.html

Can one generate/access a list of coordinates for each rendered 
note/chord (per staff)?

(I don't think it should matter that a lot of scaling happens; one could 
probably reverse the scaling through some trial & error approximation, 
in the worst case scenario)

I'm not finding a solution/answer
