More regtest differences

[Phil Holmes]

I've been comparing the result of my push of my pixel-based regtest 
comparator (b4fe233aec83383bd2e6b6170fca67a31a8c492d) with current master 
(6e4e69f2735a764eab2e6f70f83546461da0203b).  There are 2 changes that 
concern me.  The first is that it seems that all system start braces have 
been pushed a little bit further from the initial system clef.  You can see 
that if you blink between the 2 attached accidental-piano images.  Is this 
deliberate?  The second is the substantial change in the Les Nereides system 
spacing.  Deliberate?
