The shell uses libmutter which provides the whole windowing system logic as well as the interface with the rest of the windowing system (both input and output). Mutter is just a simple binary that uses libmutter internally in the same way the Shell does but without all the logic and UI provided by the Shell.

Re: How to make a GtkButton respond to a key press

Re: gtk3 toplevel windows incorrectly maximized under gnome3
I finally ran this down. The mutter window manager does indeed by default auto-maximize any newly mapped window larger than 0.8 of the 'usable screen area'. I think the latter means the space between gnome-shell's upper and lower toolbars, as I could never get anything more than about 0.75 of the total X11 display area. I still can't absolutely confirm that I'm actually running mutter because it does not appear in my system process list, and wmctrl says my WM is 'GNOME Shell'. However, the behavior I am experiencing is exactly as described within the mutter source code, and you can actually disable it via gsettings set org.gnome.mutter auto-maximize false I have to confess to enjoying some of the comments in bug reports filed on this behavior that led to the above gsettings workaround.
