Re: \applyContext, StaffSymbol, and \stopStaff \startStaff

[Paul Morris]

I found another way to do what I was trying to do.  (I used \applyContext in a 
music function to access and then modify a custom staff context property, and 
then used a custom StaffSymbol engraver to access that context property and 
change the grob properties of any new StaffSymbol grob accordingly.  A bit 
roundabout but it does the trick.)
