Yep, I've found little bits and pieces around as well, but no off-the-shelf
patch. It looks like we will just have to open libpng/src/png.c libpng/src/png.h
and the digikam and gwenview files and patch the problems for TDE.

I'm no programmer, but I think the lack of direct access to png_struct and
png_info mean we will have to add a class/struct instantation for png_struct and
png_info in each of the files that currently call the structures directly and
change the calls to use calls through the instance we just created instead.

That may be way off, but from reading and my limited understanding, that's the
rabbit trail I'm trying to follow...
