*
* Revision 6.2  2001/03/19 19:15:17  juran
* Change "for (...);" to "for (...) ;" (added space before semicolon) to silence trying-to-be-helpful compiler warning.
*
* Revision 6.1  1997/11/26 21:30:14  vakatov
* Fixed errors and warnings issued by C and C++ (GNU and Sun) compilers
*
* Revision 6.0  1997/08/25 18:56:53  madden
* Revision changed to 6.0
*
* Revision 5.2  1996/10/28 19:33:47  vakatov
* [WIN_MOTIF]  Use Nlm_VibrantDefaultColormap() instead of the display
* default colormap everywhere in the color handling code.
* Made a lot of type castings to get rid of all compiler warnings.
*
 * Revision 5.1  1996/07/25  19:48:09  vakatov
 * [WIN_X]  Added #VOID_PIXEL to serve as the tmpColorPixel's void value
 *
 * Revision 5.0  1996/05/28  13:45:08  ostell
 * Set to revision 5.0
 *
 * Revision 4.2  1996/04/24  21:20:45  vakatov

 * dialog finishing
 *
 * Revision 4.1  1996/02/27  16:31:13  kans
 * subclass folder tabs to allow SetValue (but with 0, not 1, as first value)
 *
 * Revision 4.0  1995/07/26  13:51:04  ostell
 * force revision to 4.0
 *
 * Revision 1.20  1995/05/20  18:27:38  kans
