This is done by x-display-monitor-attributes-list, which is defined in
src/xfns.c.  It uses Gdk when Emacs is configured to USE_GTK (the code
that sets the source to “Gdk” is in an #ifdef).

We build Emacs with GTK+, but … we may not need to do this as Emacs is
not a regular GTK client.  I recall that there are other oddities when
using GTK, such as crashes when disconnecting from a remote Emacs
daemon, which only happens with a GTK build of Emacs.

There may be another way to get a fully graphical Emacs without having
to build with GTK.
