Hey Nicolas, thanks for the explanation. 

So I guess that I will be able to test it, because this morning I could
get a larger workspace using xrandr to join my external monitor 
to my laptop's. And the coordinates were simply extended to higher
values.

But I thought that xinerama was different, and there would be
absolute coordinates for each head. But I never studied
the xinerama code so far, because I never used it :-(
