+	    This constructs the color from the specified
+	    System.Drawing.Color object.  Notice that the Gdk.Color
+	    structure actually uses 16-bit color values, so the byte
+	    values are mapped into the 16-bit value space.  This is
+	    just a convenience routine to initialize this structure.

+          <para>
