History


    Change History::
      Written by: David W. Fanning, 31 August 2000.
      Modified program to read colors from a file and to use more
        colors on 24-bit platforms. 16 October 2000. DWF.
      Added the COLUMNS keyword. 16 October 2000. DWF.
      Fixed a small problem with mapping a modal widget. 2 Jan 2001. DWF
      Now drawing small box around each color. 13 March 2003. DWF.
      Added eight new colors. Total now of 104 colors. 11 August 2005. DWF.
      Modified GUI to display system colors. 13 Dec 2005. DWF.

      Added all BREWER names to the default naming scheme. 3 July 2008. DWF.
      Set a size for the color name label widget. Otherwise, the widget always
          jumps back to the center of the display when I select a color on UNIX
          machines. Also had to remove TLB updating with UPDATE keyword to avoid
          tickling the same IDL bug. Sigh... 13 March (Friday) 2009.
