This is a library for OpenGL to load PNG graphics files as an OpenGL texture as
easily as possible. It also has a number of options for generating the alpha
channel and mipmaps. It is implemented using modified versions of the LibPNG
1.0.2 and ZLib 1.1.3 libraries.

 Installation for MSDEV

 Copy glpng.h to your include/GL folder and copy glpng.lib and glpngd.lib to
your lib folder. Then just do #include <GL/glpng.h> and with a bit of luck,
MSDEV will automatically link with glpng.lib (release lib) or glpngd.lib (debug
 Installation for Any Other Compiler

 Copy glpng.h to your include/GL folder. Then you'll have to build the library
yourself with the included source code. Included are makefiles for Linux and
SGI. If you need to modify the source code to make it work on your system,
please get in contact so I can make future versions compatible.
 Compiling with LibPNG or ZLib

 If you are using LibPNG or ZLib in your project there may be problems if you
link with the glpng library. To solve this, include glpng.c in your project and,
if you're using MSDEV, modify glpng.h to not automatically link with glpng.lib
or glpngd.lib.
 OpenGL DLL Dynamic Loading using glsetup

 To use glpng with glsetup, include glpng.c, LibPNG and ZLib in your project. In
glpng.c, change #include <GL/gl.h> to include the glsetup include and modify
glpng.h to not automatically link with glpng.lib or glpngd.lib.
