The internal function idea is now bunk - you're right about the positions thing.

The issue is that, for the chord bracket and chord slur (and Bertrand's 
eventual chord brace, which hypothetically varies significantly in its X 
dimension as it gets larger), the width of the grob is dependent on knowing the 
extremal note head positions, which triggers a vertical alignment.  Any 
suggestions on how to get this information without triggering the vertical 
alignment?
