Yeah: Just compile *any* Lilypond document.  ;)

In all seriousness: I've broached the subject with Mike S (in his role as my 
"developer for hire"), and he seems to think it might be too complex. I want 
each grob to have settings which:
    1. give the axis/es along which it is allowed to be pushed in order to 
avoid collisions;
    2. force the associated moment to move/stretch under the adjusted grob, if 
horizontal movement is allowed.

For example, an articulation (Script) would move vertically only. Tempo 
indications (MetronomeMark) might move to the right only, and wouldn't pull the 
associated moment. BarNumbers could move left or right (but not up or down). 
And so on.

I would love to get a discussion/brainstorm going with multiple developers, to 
see whether my scheme might be possible without too much trouble.

Best,
Kieren.
