Tanks to this \assignIDs function and the information in the svg its pretty easy to find the correct location of a given symbol.
The problem im stuck with right now is creating meaningful labels. The way the ID is constructed right now is Name+Momentum?+RelativeLocation. And i am not able to tell eg. bass and treble clefs apart.
Is it possible to dump more information about the grob this id tag? Such that it is unique to what symbol is printed.
I am totally new to lilypond, sorry if I spam you with trivial questions. If you could point me to the relevant parts of the doc it would already help.
cheers

Hm, but at some point LilyPond *has* to know where objects are placed,
isn't it?
Isn't there anything like a parent hierarchy that could be walked up
like a breadcrumb navigation that eventually leads to coordinates
relative to a page corner?
(Of course this is closely related to my question
