 All distances in the CGM file are in abstract units.  The application
 that reads the file determines the size of the final plot.  By default,
 the width of the final plot is assumed to be 6 inches (15.24 cm).  This
 distance is used to calculate the correct font size, and may be changed
 with the `width` option.  The keyword should be followed by the width in
 points.  (Here, a point is 1/72 inch, as in PostScript.  This unit is
 known as a "big point" in TeX.)  Gnuplot `expressions` (Note: Expressions )
 can be used to convert from other units.

 Example:
       set terminal cgm width 432            # default
       set terminal cgm width 6*72           # same as above
       set terminal cgm width 10/2.54*72     # 10 cm wide
