  32 ** For each screen, generates NeWS PostScript commands on stdio
  33 ** capable of doing X11/NeWS-specific initialization when executed.
  34 **
  35 ** Output is of the form:
  36 **
  37 **      <scr_num> <ncolors> cmap_compact_rearrange_scr
  38 **      <scr_num> <ncolors> cmap_compact_rearrange_scr
  39 **      ...
  40 **
  41 ** where <scr_num> is the screen index of each screen,
  42 ** <ncolors> is the number of saved colors, and 'cmap_compact_rearrange_scr'
  43 ** is a NeWS routine which performs rearrangement of various predefined
  44 ** colors to further reduce colormap flashing with other X11/NeWS
  45 ** programs.
