Can somebody please explain what the expression in vwidth.c:
	w = desc[cl].width * (54./25.) * (6./psize) + .5;
is doing?  I mean where does 54, 25 and 6 come from?
I am trying to get typesetter independent troff to work with the versatec
fonts on the imagen laser printer and am going wacky trying to figure
out the relationship between ``res'', ``unitwidth'' and the character
widths in the individual font width files and the widths in the actual
vfont files and the widths in the files supplied by bell for use with the
canon.
