Re: The mystery of vertical spacing

[Paul Hodges]

Setting that option draws coloured lines along the skyline.  At first 
glance the lines hug the notation tightly throughout, as I'd expect.  
But in the first line of the piece there are a couple of small oddities. 
(1) towards the end of the third staff (bar 7, secondo), the top skyline 
has a blip which doesn't relate to any object, except perhaps it relates 
to (2) at the same place in the staff below there is a tuplet bracket 
and clashing dynamics (which I intended to revisit later) which are 
outside the "skyline" (do you have a name for the underneath one?).

It occurs to me that this might be related the two occurrences of the 
error: "programming error: cyclic dependency: calculation-in-progress 
encountered for #'adjacent-pure-heights (VerticalAxisGroup); continuing, 
cross fingers" which I have had since writing that page.

Beyond that, I have to admit that this score has a lot of what seem to 
me to be pretty extreme excursions outside the staves, but all seem 
reasonably logical to me.
