I frequently need do something like:  <c \tweak font-size #-2 c'> in order to 
show that one of the two notes is preferred, but the other one is acceptable.  
The problem is that the "-2" in the \tweak command is an absolute value, i.e., 
it is not relative to the fontSize being used.  If the fontSize were -3, e.g., 
then the "smaller" note would actually be bigger than the preferred one.

What I would like to do is substitute for the "-2" the value "fontSize-2".  Is 
this possible?  If so,how?
