Libpng was maintained as a collection of files on a computer by the 
maintainer.  The collections of files were turned into release 
tarballs.

After many years someone contributed a script (discussions of this 
script should be archived for this list) which allowed Glenn to 
convert the many release tarballs into a git repository.  Even after 
this, the convention seemed to be to import releases into git from a 
release tarball even though someone had made direct commits to the 
repository.

To the best of my knowledge, the primordial git repository for libpng 
is available for viewing at 
"http://src.simplesystems.org/git?p=libpng.git;a=summary" and I have 
daily snapshots for the filesystem in which it resides (can reproduce 
the underlying git files corresponding to any day) going back to 
January 1st, 2012.
