This is a huge undertaking, that requires changes in Emacs all over the place.
Coordinates and sizes are used in many places.
I'm not sure its worth it, as this Gnome thing is a bad way to scale
applications (it requires applications to conform to Gtk+).
KDE does something different for example. So I'm guessing something better
will emerge.

Emacs is not a Gtk3 application, ut just uses some of its widgets.
Its more of a raw X11/Gtk3 hybrid.
