glutCopyColormap  -  copies  the  logical colormap for the
       layer in use from a specified window to the  current  win-
       dow.

SYNTAX

       void glutCopyColormap(int win);

ARGUMENTS

       win       The identifier of the window to copy the logical
                 colormap from.

DESCRIPTION

       glutCopyColormap copies (lazily  if  possible  to  promote
       sharing)  the  logical colormap from a specified window to
       the current window's layer in use. The copy will  be  from
       the  normal plane to the normal plane; or from the overlay
       to the overlay (never across  different  layers).  Once  a
       colormap  has been copied, avoid setting cells in the col-
       ormap with glutSetColor since that will  force  an  actual
       copy of the colormap if it was previously copied by refer-
       ence. glutCopyColormap should only be called when both the
       current window and the win window are color index windows.

EXAMPLE

       Here is an example of how to create two color  index  GLUT
       windows  with  their  colormaps  loaded identically and so
       that the windows are likely to share the same colormap:

         int win1, win2;

         glutInitDisplayMode(GLUT_INDEX);
         win1 = glutCreateWindow("first color index win");
         glutSetColor(0, 0.0, 0.0, 0.0);  /* black */
         glutSetColor(1, 0.5, 0.5, 0.5);  /* gray */
         glutSetColor(2, 1.0, 1.0, 1.0);  /* black */
         glutSetColor(3, 1.0, 0.0, 0.0);  /* red */
         win2 = glutCreateWindow("second color index win");
         glutCopyColormap(win1);
