I do appreciate the "teach a man to fish" approach…

I've poked around at the \dynText function, and the \dynamic function in 
OpenLilyLib (see snippet, below, for original version), but have been as yet 
unable to incorporate self-alignment-X into the callback(s) for the offset in a 
way that seems to work.

Any further help or pointers (e.g., to a callback function which *does* 
incorporate self-alignment-X) would be welcome.

Thanks,
Kieren.
