Re: uniform-stretching

[Orm Finnendahl]

Hi Trevor,

thanks very much for getting back to me! I just downloaded and tried
it. Spacing seems much better controllable, but lilypond segfaults now
for parts of the score (it doesn't segfault in 2.11.0), so I can't
really tell until I've found out what causes the segfault.

There is one issue now: The time signatures are printed above the eps
graphics (instead of below) and aren't horizontally aligned anymore (I
haven't found out why they are doing it as they don't exactly follow
the contour of the top voices). Both, time signatures and eps graphics
are done using text markup. Has anything changed in the specs? It'd be
really painful if I had to do this all over again...

I can put the score somewhere but I first want to find out, what's
wrong. It's probably hard to isolate the problem to a short code
snippet in order to post a small example in the mail.
