<event name="new_output" since="4">
<description summary="notify of a new wl_output">
This event indicates that one or more new outputs have been
created. All clients must send an ack_new_output request in response
to this event. If a client wishes to create a new layer surface in
response to the new output(s), it must make an ack_new_output request
with the provided serial after creating any new layer surfaces using
the get_layer_surface request and before the first commit on any of
the new surfaces. If the client does not wish to create a new layer
surface, it should ack immediately.
This allows the compositor to wait until new layer surfaces are ready
before rendering the first frame of new outputs, avoiding a race that
could cause imperfect frames.

<request name="ack_new_output" since="4">
<description summary="ack a new_output event">
This request informs the server that the client has created all
layer surfaces it intends to create in response to the new output(s).
These new layer surfaces are associated only with this ack sequence
and do *not* carry over to following ack sequences should any occur
before the first commit on the surfaces.
If the client receives multiple new_output events before it
can respond to one, it only has to ack the last new_output event.
