Another set of these picture files, including their actual picture data,
resides in the 'extra administrative stuff' Git repository (lilypond-extra).

IMO the actual content of these files should live in the $LILYPOND_GIT
repository, not in the lilypond-extra ($LILYPOND_WEB_MEDIA_GIT) repository.

Presumably, the reason for the existence of this 'extra administrative
stuff' Git repository is to keep separate (and perhaps more secure) some
various files which exist solely for purposes orthogonal to LilyPond: i.e.,
to meet the needs of (or to correct problems caused by) some particular (and
not general) website hosting software, or for other security purposes.

If, in our 'extra administrative stuff' Git repository, we maintain
pictures, as well as (perhaps) files which exist for reasons other than the
above ones, then IMO we're asking for trouble at some future time, and
needlessly complicating our build process.

The following demonstrates that the 'extra administrative stuff' repository
holds the actual contents of these files:

$ cd ~/lilypond-extra
$ find * -name 'lily-home-32x32.png'
pictures/lily-home-32x32.png

$ git log --full-history pictures/lily-home-32x32.png
