I have never attempted to customize gnome-shell.  If it can be
customized with custom themes, different fonts and what not, then I
think it makes sense to keep the user-choosable art assets as
gnome-shell-assets.

Otherwise, if it's not configurable and expects only a specific font,
specific icons, etc., then it seems it'd make sense that it finds them
out of the gate (wrapped from within a phase).

Could someone confirm whether GDM is configurable when it comes to icons
and fonts?

Thanks for working on it, Dariqq!
