 Note: that file has changed a great deal in 7.0 (and may well change
 further), so don't pay too much attention to anything contained in it.

 In 7.0, the "U" coordinates aren't required to be cartographic
 coordinates, e.g. d.graph uses percentages (i.e. coordinates range from
 0,0 to 100,100). Also, physical coordinates (pixels, points) are hardly
 used now by d.* commands. The only remaining vestige is that the
 conversion factor is often used for sizing text and certain other elements
 (e.g. symbols).
