* $Log:: /JP2_PC/Source/Test/FastBumpTest.cpp $
*
* 12 96/12/31 17:08 Speter
* Updated for rptr and new CRaster funcs.
*
* 11 96/10/28 15:00 Speter
* Updated for new UpdateCluts interface.
*
* 10 96/10/04 18:07 Speter
* Removed include of defunct ObjDef*D.hpp files.
*
* 9 9/24/96 3:00p Pkeet
* Not working, but didn't want them hanging around.
*
* 8 96/09/16 12:26 Speter
* Updated for simplified CBumpMap structure.
*
* 7 96/09/13 14:49 Speter
* Corrected variable prefixes.
*
* 6 9/11/96 11:39a Pkeet
* Changed references of 'pcePalClut' to 'ppcePalClut,' added the 'ObjDef3D.hpp' include.
*
* 5 9/06/96 6:01p Pkeet
* Moved lookup functions to external assembly routines.
*
* 4 9/05/96 6:34p Pkeet
* Changed bumpmap to use the 'CRasterSimple' class. Added lighting parameters to the
* 'MakeBumpmap' Table function.
*
* 3 9/05/96 2:28p Pkeet
* Added texturing to bumpmapping.
*
* 2 9/04/96 5:16p Pkeet
* Added file-based bumpmaps.
