New issue 1954 by percival.music.ca: request: filter point-and-click  
creation by events
http://code.google.com/p/lilypond/issues/detail?id=1954

I'd like to limit the number of point-and-click events in the ps/pdf  
output.  In my particular case, I want to only have point-and-click for  
noteheads.

\version "2.14.0"
\layout { \context { \Score
  % I don't care if it's an \override, \set, \tweak, #(scheme), or  
\smoke_signal
  #(filter-point-and-click 'NoteHead)
} }

\relative c' {
  c2\f( f)
}

should produce a pdf with only two textedit links (the notes), not four  
(the unwanted ones being the slur and dynamic).

Additional notes:
- in order for this to be accepted to git, you might need to implement a  
flexible system to select any specified music-events, instead of  
hard-coding "only note-events".  That's between you and the other  
developers, not me as a user.
- I don't care if it's a "only output these specified music events" filter,  
or a "do not output these specified music events" filter.
- no documentation needed.  The above code should be added as a regtest,  
although no automatic testing of the actual pdf is needed (the only point  
of this regtest is to make sure the construct still compiles, not that it  
actually works)
- I think you'd want to start the filtering on line 167 of scm/output-ps.scm


I'm offering a trade: 2 hours of my time working on something of your  
choice (documentation, administration, releases, gub, patches, lsr, etc) if  
you implement this.
