As for (b), I wanted to add png versions:
http://lists.gnu.org/archive/html/lilypond-devel/2009-08/msg00730.html
but I've been told off in the past for adding files that could be
added automatically.  Since nobody said "sure, go ahead", I
figured I should generate them from the svgs.  It took me over two
hours to get the svg->png creation, not counting whatever time
Patrick spent on the process as wel.

I don't understand what you mean by touching the files in advance,
which isn't surprising since I've never tried to learn make or our
makefile process.

When I do a "make doc-clean" in Documentation/pictures/, followed
by a "make doc", my version of imagemagick (6.3.7, from a standard
debian/stable install) creates png images.  Patrick is IIRC using
6.5.1, so I figured that there wouldn't be problems using convert.
If necessary we could use inkscape or rsvg, but I'd rather not
increase the build requirements.  (IIRC inkscape isn't required
for master)
