+ <request name="set_app_split" since="11">
+ <description summary="set the application split">
+ This requests asks the compositor to change the application from the
+ original mode (whatever that might be) to a split, tiled orientation
+ mode defined in the tile orientation enum.
+ Clients need to implement resizing (to handle xdg-shell configure
+ events) for this to work correctly.
+
+ This request only handles a single level of tiling for practical
+ reasons: to keep implementation simple and straight forward. The
+ compositor will ignore requests if there are already two windows
+ present. The client can verify this request succeed by checking the
+ xdg-shell configure event and with it, the states sent
+ by the compositor.
+
+ If there's no app_id with the supplied name, the compositor will add
+ the app to a pending list in order to be applied when an application
+ gets started, or if the application sets its application after the
+ initial wl_surface.commit request.
+
+ Applications can use this approach if they want to be started in a
+ tiled orientation position, before creating the xdg-shell toplevel role.
+
+ A none orientation type would make the window go back to the original
+ maximized mode. If two windows are side by side, returning one of them
+ back the original mode would mean the other one will be made hidden
+ and the one doing the request for the none orientation will become
+ the currently active window. A further activation, using activate_app
+ request for the other window would make that one active.
+
+ Closing the window in the tiled orientation state implies that either
+ the background surface will displayed, or in case there was another
+ applications being shown at that time, will make that application be
+ returned to the original, maximized state.
+
+ The tiled orientation could be applied independently of each other,
+ such that a client can transition from one tiled orientation to
+ another. Note that any other window already present would literally
+ take the opposite orientation with the one currently being changed. So
+ tiled orientation modification automatically implies a tile orientation
+ for any other application already present/active at that time.
+
+ In case there's already a client active at that time, it will be
+ attributed automatically the opposite tiled orientation, such that two
+ concurrent applications can be displayed at the same time.
+
+ The orientation tiles can not be combined, and only state at a time
+ can be active. Only horizontal and vertical tiling is possible. A
+ horizontal and vertical tile orientation simultaneously is not
+ possible.
+
+ Input focus is being delivered to the last started/activated window,
+ such that users can cycle between that one or the other, assumes there's
+ another window in the first place.
+
+ See xdg_toplevel.set_app_id from the xdg-shell protocol for a
