I can't remember much about CGM, to tell you the truth, but I think it
lacks features.  You would know better than I, but is there support for:

	* Bezier curves
	* line widths of essentially infinite variation?
	* dashed lines
	* true grey and color halftoning (as opposed to pattern filling)
	* rotated text
	* full CMYK color model
	* clipping

It wouldn't take very many of these features missing to make it unsuitable
for document interchange, especially from/to environments that use
PostScript regularly (like the Mac and the NeXT).
