OK, I guess that's the other sensible explanation; I just didn't think of it
(somewhere I still remember my first peeks and pokes ;) )

I have no idea what points are, but I have a problem with the idea of turning
on or off the umptieth of a pixel :)

I trust Apple to make that work even if you leave the window spanning multiple
screens, but the question was about XQuartz. Sorry I didn't mention that

True, and the value obtained from the hardware was rarely reliable either (in
my experience at least).

LOL, you're welcome and goodmorning :) I don't know about XQuartz, but I've had
to figure out the modelines issue when adding new modes to the list on my Linux
systems (xrandr --newmode "1366x768" 85.25 1366 1440 1576 1784 768 771 781 798

That's probably a good enough workaround for the OP for now.

How so? If you want 100x100 px and you get 100x100px you got what you asked for
Afterwards you just have to change your configuration, starting with Xft.dpi,
and the window sizes you request. Not a problem as far as I can see, as long as
you don't try to use those same settings on a regular display (and you don't
depend on bitmap fonts only available for lower resolutions) ...
Mostly unrelated: do you happen to know if anyone has considered or discussed
bringing Wayland to the Mac?
