VisPatch is a tool for patching quake maps for transparent water in
glquake. Original quake didn't have their maps water-vis'ed, so people
did that by themselves and prepared patch data files. This tool is used
for preparing and applying those patch files.

At the time this tool was written, re-vis'ing maps took a lot of
time, but applying a vispatch took less than minutes, so this was a
necessity. Even today, if people don't want going into a 'complex' job
of vising, this tool comes as a great convenience because there are a
lot of vispatch data files around.

This is a revised version of Andy Bay's 1.2a source code for unix
(linux, freebsd, ...), as well as windows. It fixes a number of
compilation issues, crashes and some other bugs, and resolves
endianness issues. The source code is licensed under GPLv2, and is
maintained here with portability in mind.
