This mechanism doesn't exist until Attachment #328512 is (reviewed and) merged.

Having a simple flag for TILED exactly matches the GDK API here, and is
sufficient to preserve X11 functionality under Wayland (rectangular window
decorations when tiled, and reporting the tiled status to application code). I
think there's a risk of letting the perfect be the enemy of the good: can we
land the simple version that is sufficient to implement the current GDK API,
then leave the bug open (or clone another bug) for enhancing it to describe
more elaborate encodings if desired?
