   Resources recognized by NetPlot widgets.  Since NetPlot widgets use more
   than one foreground color, you should use the class Foreground to set
   all foreground colors to a single color, e.g. "NetPlot*Foreground" vs.
   "NetPlot*foreground".

   Name			Class		RepType		Default Value
   ----			-----		-------		-------------
   background		Background	Pixel		White
   foreground1		Foreground	Pixel		Black
   foreground2		Foreground	Pixel		Black
   foreground3		Foreground	Pixel		Black
   foreground4		Foreground	Pixel		Black
   hilight		Hilight		Pixel		Black
   font			Font		FontStruct	?
