* Usage:
* 1. foreign-toplevel
* Prints a list of opened toplevels
* 2. foreign-toplevel -f <id>
* Focus the toplevel with the given id
* 3. foreign-toplevel -a <id>
* Maximize the toplevel with the given id
* 4. foreign-toplevel -u <id>
* Unmaximize the toplevel with the given id
* 5. foreign-toplevel -i <id>
* Minimize the toplevel with the given id
* 6. foreign-toplevel -r <id>
* Restore(unminimize) the toplevel with the given id
* 7. foreign-toplevel -c <id>
* Close the toplevel with the given id
* 8. foreign-toplevel -m
* Continuously print changes to the list of opened toplevels.
* Can be used together with some of the previous options.

<description summary="list and control opened apps">
The purpose of this protocol is to enable the creation of taskbars
and docks by providing them with a list of opened applications and
letting them request certain actions on them, like maximizing, etc.
After a client binds the zwlr_foreign_toplevel_manager_v1, each opened
toplevel window will be sent via the toplevel event
</description>
<event name="toplevel">
<description summary="a toplevel has been created">
This event is emitted whenever a new toplevel window is created. It
is emitted for all toplevels, regardless of the app that has created
them.
All initial details of the toplevel(title, app_id, states, etc.) will
be sent immediately after this event via the corresponding events in
zwlr_foreign_toplevel_handle_v1.
</description>
<arg name="toplevel" type="new_id" interface="zwlr_foreign_toplevel_handle_v1"/>
</event>
<request name="stop">
<description summary="stop sending events">
Indicates the client no longer wishes to receive events for new toplevels.
However the compositor may emit further toplevel_created events, until
the finished event is emitted.
The client must not send any more requests after this one.
</description>
</request>
<event name="finished">
<description summary="the compositor has finished with the toplevel manager">
This event indicates that the compositor is done sending events to the
zwlr_foreign_toplevel_manager_v1. The server will destroy the object
immediately after sending this request, so it will become invalid and
the client should free any resources associated with it.
</description>

A zwlr_foreign_toplevel_handle_v1 object represents an opened toplevel

Each toplevel has a list of outputs it is visible on, conveyed to the
client with the output_enter and output_leave events.

Send a request to the toplevel to close itself. The compositor would
typically use a shell-specific method to carry out this request, for

no guarantees the toplevel will actually be destroyed. If and when

The rectangle of the surface specified in this request corresponds to
the place where the app using this protocol represents the given toplevel.
It can be used by the compositor as a hint for some operations, e.g
minimizing. The client is however not required to set this, in which
case the compositor is free to decide some default value.
If the client specifies more than one rectangle, only the last one is
considered.
The dimensions are given in surface-local coordinates.
Setting width=height=0 removes the already-set rectangle.

This event means the toplevel has been destroyed. It is guaranteed there

destroy request.
