Ok, I get it now. You're not really adding two coordinates, which would
of course be silly. What you're actually doing is interpreting the llx
and lly coordinates as distances -- the distance that the imaging area is
offset inwards from all sides of the physical page. Then adding the margin
distances to the urx and ury imaging coordinates gets you the urx and ury
physical coordinates -- assuming, as you say, that the imaging region is
centered.
I'll change my code, and add a big comment crediting this disgusting hack
to you...
