PSWIGB - PostScript WIGgle-trace plot of f(x1,x2) via Bitmap		
 Best for many traces.  Use PSWIGP (Polygon version) for few traces.

 curvewidth=axeswidth   width (in points) of curve(s)                  

 Notes: 								
 The interp option may be useful for high nbpi values, however, it	
 tacitly assumes that the data are purely oscillatory.	Non-oscillatory	
 data will not be represented correctly when this option is set.	

 The curve file is an ascii file with the points specified as x1 x2	
 pairs, one pair to a line.  A "vector" of curve files and curve	
 colors may be specified as curvefile=file1,file2,etc. and 		
 curvecolor=color1,color2,etc, and the number of pairs of values in each
 file as npair=npair1,npair2,... .					

 All color specifications may also be made in X Window style Hex format
 example:   axescolor=#255
