Bug#666010: ITP: nvidia-texture-tools -- image processing and texture manipulation tools

[Fabio <fabio.ped@libero.it>]

If you are packaging 2.0.8 please have a look at the README.txt and patches at:
http://trac.wildfiregames.com/browser/ps/trunk/libraries/nvtt/

The issue139.patch is particularly important: it fixed image corruption I 
noticed on 0.A.D., see here:
