|*|             This implementes a ComboBox control that can be
|*|             used to display and provide selection for a specific
|*|             set of colors.  The standard set of colors provided
|*|             by the control are a subset of the X11 colorset, and
|*|             are the ones available in (and the color names 
|*|				recognized by) Internet Explorer.
|*|             
|*|				The ComboBox that is subclassed must have the 
|*|             Owner Draw Fixed and Has Strings styles.
|*|             
|*|             This is based on code that was originally found on
|*|             CodeGuru, and was © 1997 Baldvin Hansson.
|*|             
|*|             A bug fix by Marcel Galem was added to provide
|*|             correct masking of the COLORREF values.
|*|             
|*|             DDX routines were provided by Paul Wardle
