SVN commit 773569 by rahn:

2008-02-11  Torsten Rahn  <rahn@kde.org>

    * data/CMakeLists.txt:
    * src/lib/TextureColorizer.{cpp,h}:
    * src/lib/texturepalette.cpp: deleted

    Patch by Ismael Asensio to make marble use the .leg files 
    instead of using the hardcoded values in texturepalette.cpp.
