This is a modified version of LibPNG for use
with the GraphApp library.

This version of LibPNG is based on version 1.2.3
of LibPNG, available from www.libpng.org.

The only modifications are that I've changed the
#if 0 construct into #ifdef DO_NOT_COMPILE in
pngconf.h (since some compilers have trouble with
#if 0 for some reason), and I've also made some
small modifications to zLib, upon which LibPNG
relies. See the README.TXT file in libz/ for
more details.

Since the real version of LibPNG is available
from the net, you may upgrade to the latest
version by downloading it from www.libpng.org
and extracting it into this folder and compiling.

I've taken the liberty of removing some unused
files and documentation and subfolders. See the
real version for these removed files or folders:
