Hey all,

The most recent patch set implements more intelligent padding to avoid  
cases like comment 113.

The problem now is that padding could be more intelligent.  For example,  
you'll see that in the regtest comparison, midi-pedal.ly changes because  
the "d" of "tre corde" is too close to the Sostenuto marking, which shifts  
the Sostenuto down.  This has to do with how padding is currently  
implemented: it is tacked on as a sort of bubble around objects before  
measurements are taken and not a posteriori.  This prevents things from  
being too snug but has the disadvantage of causing certain things that were  
not formerly collisions to now be treated as such.  I'm not sure of a good  
way to fix this for now...it'd require more sophisticated notions of  
padding.  All suggestions are welcome.  It only comes up in this regtest  
(from what I can see) and it solves problems like that in comment 113.
