// $Log: typeview.h,v $
// Revision 1.9  2004/11/12 22:14:16  bseifert
// Eliminated CLR_NONE. Minor corrections.
//
// Revision 1.8  2004/11/12 00:47:42  assarbad
// - Fixed the code for coloring of compressed/encrypted items. Now the coloring spans the full row!
//
// Revision 1.7  2004/11/08 00:46:26  assarbad
// - Added feature to distinguish compressed and encrypted files/folders by color as in the Windows 2000/XP explorer.
//   Same rules apply. (Green = encrypted / Blue = compressed)
//
// Revision 1.6  2004/11/05 16:53:08  assarbad
// Added Date and History tag where appropriate.
//
