Correct in all cases, although when "X -configure" creates those values
from DDC it currently uses a size derived from the monitor size in cm,
rather than the size in millimetres of any particular mode.
The screen dimensions reported by xdpyinfo are those calculated from
the pitch - DPI - which is in turn calculated from the DisplaySize;
rounding errors mean that the two sets of dimensions may not be the
same :-(
X -configure comments these values out because many apps used to get
confused by having precise dpi values and displayed silly fonts.
I think that at one time a 85x90 dpi screen would make Netscape
use 75x100dpi fonts. I note that Netscape 7 allows you to calibrate
the horizontal screen pitch, but not the vertical pitch.
