One more understanding question regarding contexts and engravers.
If I \consist an engraver in a bottom context like Voice I can travel
up the chain of parent contexts, retrieving their name and id
properties. But if I \consist it in Staff level contexts I don't see
if/how I can get to the bottom-level context a grob is possibly in.
To be in any meaningful way "in a bottom-level context", a grob needs to
be made by an engraver at bottom level. In that case you can call
ly:translator-context on the third argument of the grob acknowledger
which is the _source_ engraver rather than the current engraver.
OK, I have tested how this works, and I see how I can retrieve the
lowest context of any given grob. But if I'm not mistaken this is only
possible in acknowledgers, isn't it? But I have to get to that context
in process-acknowledged or stop-translation-timestep.
By now I would know how to link that information to the grob in
acknowledgers and read it later - but that would mean I have to look up
the source-engraver context for *all* grobs and not only for those (the
annotated grobs) where I actually need them.
