<protocol name="dwl_ipc_unstable_v2">
<description summary="inter-proccess-communication about dwl's state">
This protocol allows clients to update and get updates from dwl.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible
changes may be added together with the corresponding interface
version bump.
Backward incompatible changes are done by bumping the version
number in the protocol and interface names and resetting the
interface version. Once the protocol is to be declared stable,
the 'z' prefix and the version number in the protocol and
interface names are removed and the interface version number is
reset.

<description summary="control the dwl state">
This interface is exposed as a global in the wl_registry.
Clients can use this protocol to receive updates of the window manager
state (active tags, active layout, and focused window).
Clients can also control this state.
After binding, the client will receive the available tags and layouts
with the 'tag' and 'layout' events. These can be used in subsequent
dwl_wm_monitor_v1.set_tags/set_layout requests, and to interpret the
dwl_wm_monitor_v1.layout/tag events.
