BTW -I specify that -dpi setting in /etc/X11/xinit/xserverrc
exec /usr/bin/X11/X -dpi 100 -nolisten tcp

Thanks for the great explanation. It makes sense, really. 72 points
should be an inch on the screen.
(Although if you run a high resolution on a smaller monitor and X
adjusts the fonts to keep a 72point font 1" then images will look small
compared to the text. Oh well.)
So, if I'm following, if X knows my physical screen size, it should be
able to render fonts to the correct point size.
So I set in XF86Config-4 in my "monitor" section:
DisplaySize 362 273
Now, if I run X like this:
xinit /usr/local/bin/sylpheed -- /usr/bin/X11/X
and I set up sylpheed to use a TT font (I'm running xfstt).
-ttf-courier new-medium-r-normal-*-14-*-*-*-m-*-iso8859-1
Now, changing screen sizes (Ctrl-Alt-+) my fonts do change relative to
the screen size.
I tried with other applications, too, such as gedit, mozilla, kedit.
Removing DisplaySize seems to have no effect, either. Passing various
-dpi settings to X doesn't seem to do anything either.
My conclusion is that I must still not understand. :(
My head hurts.
Thanks,
