[Arnaud B. <arnaudb src gnome org>]

commit 64a772fad6d9541dd0919072f18e23c723ee43be
Author: Arnaud Bonatti <arnaud bonatti gmail com>
Date:   Mon Jun 1 20:31:53 2020 +0200

    Simplify UI file.
    
    The overlay only applies to
    the game_box and the window
    can be set black without an
    unneeded box for one child.
