Re: change barline type with time signature change

[Kieren MacMillan]

Hi Jan-Peter (and anyone else still interested in this thread):

In the end, the conductor of my chamber opera asked to have the bar lines solid 
for all measures, but 50% grey and slightly thicker than default as the 
"baseline", and black and slightly thicker still for bar lines concurrent with 
a time signature change — I easily adapted the engraver and my context defaults 
to suit.

He is thrilled with the result**, and hence so am I.
(** He goes so far as to say that this should be the standard notation 
practice!)

Thanks again,
Kieren.
