When I switched to TrueColor on my Linux box, I found that xfishtank just crash
with a segmentation fault, how frustrating. Digging into the code, I found
that it only support depths 1-8. Thanks to John Cwikla's article:

    The X Color Context: Color Management For (Almost) Any Occasion
     in The X Advisor: June 1995 - Vol 1 No 1. http://www.unx.com/DD/advisor

I got xfishtank to support TrueColor. I've only tested it on Linux running
XFree86-3.1.2 in 16 and 24 bpp. If anybody can get it to work on other
platform or other video modes, please drop me a line.

I have no idea what this version will do in DirectColor modes because I have
no way of testing. This version ignores the -C (color limit) flag when running
in > 8 bpp modes. There's no need for limitting the number of color in
TrueColor modes right?

You may use, redistribute this version as long as you keep all the READMEs and
copyright stuff with the code. This is to ensure credit goes to those deserve.
After all, I did not write this code. I only add TrueColor support.

There no warranty of any kind. Use this code at your own risk. Don't blame me
for any damage it may cause. Bugfixes and comments are welcome.

Enjoy,
