Hi all!

Right now, the resulting .ps contains link information for the noteheads, pointing to the row and charachter in the source .ly file (for example "textedit://c:/test.ly:14.2.2").

It would be very useful if there could be alternative information in this link, for example:

    * x and y position for the notehead (using some kind of universal
      unit)
    * note-pitch for the notehead (defining it's pitch, for example
      midi note)
    * note-duration for the notehead
    * ...

Maybe this information could be joined into a query-style string, for example
"note-info:x=640&y=232&pitch=64&duration=128"

Even better would be the export of a kind of "scoreinfo" xml, containing the information above - thus linking the musical content and objects on the exported picture together...

This way, it would be simple to use the lilypond output in other applications, for examle making notes clickable with sounding result.
