Here's my first question.  It concerns the 'layer property.  I'd assumed all 
objects were placed in layer 0 by default, and objects which were processed 
first were overwritten by objects processed later.  To check this I tried 
colouring bar lines white, and indeed found that they overwrote the staff 
lines unless I set the StaffSymbol layer to 1.  So far so good.  I placed 
this example in my local copy of the NR to demonstrate the overwriting:

@lilypond[quote,verbatim,relative=2]
a1 a
\once \override Score.BarLine #'color = #white
a a
@end lilypond

but then found that the staff lines in the NR are not reliably overwritten - 
sometimes they are, sometimes they are not.  I can't see any pattern in 
this.  So far the overwriting is always as expected if I compile this 
example separately to a pdf.  Any ideas?  Or are my initial assumptions not 
correct?
