    libgimpwidgets: make color chooser scales range to 100.0 instead of 255
    
    Still using perceptual TRC - making 50% middle gray.  This for all of 8bit and
    16bit integer, as well as for floating point precisions. Also added a decimal point, to make use of more 
precision for both RGB and HSV entries.
