 $Log: TCCreateTPL.cpp,v $
 Revision 1.2  2008/05/23 04:26:10  iwai_yuma
 Improved for handling of VC2005.

 Revision 1.1  2006/02/17 09:01:53  mitu
 1st version

    
    3     4/11/01 3:08p John
    Updated header copyrights and pathname.
    
    2     3/17/00 1:19p Mikepc
    change tc to use indices numbered from 0.
    
    1     12/03/99 3:45p Ryan
    
    16    10/08/99 2:45p Mikepc
    update for tplConv portability: altered data structures, replaced
    references to 'read tga code' with ' *fileFn, removed redundant
    functions.  Changed some file conversion paths.
    
    15    9/16/99 8:47p Mikepc
    updated code for auto-palette generation
    
    14    9/07/99 3:05p Mikepc
    removed default directory restriction from ConvSi2Dds().  tga files can
    now originate in any directory.
    
    13    9/07/99 10:20a Mikepc
    changed a couple of comments to improve clarity.
    
    12    9/02/99 11:12a Mikepc
    some code re-organization between files.
    added code (verify.cpp) to invoke s3tc.exe from within tc program.
    changed some routines to accommodate the new texture creation path.
    
    11    8/26/99 4:59p Mikepc
    renamed file extensions from .c to .cpp.
    .cpp extension allows addition of namespace protection to remove
    potential name collisions with tool code.  Exceptions are CreateTplFile
    and QuickConvert.  These are extern "C" linked.
    
    10    8/26/99 11:38a Mikepc
    
    9     8/26/99 11:03a Mikepc
    tplCon rewrite for efficient memory usage, batch file processing
    ability.
