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

 Note:  linewidth=0.0 produces the thinest possible line on the output.	
 device.  Thus the result is device-dependent, put generally looks the	
 best for seismic traces.						

 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 similarly		
 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
