-+Transmitter plugin
-+
-+The current implementation of Transmitter is a stub which interfaces to
-+other Weston parts appropriately, but all networking is just a mockup.
-+
-+Sections in this file describe:
-+- How to build
-+- How to write weston.ini
-+- How to test
-+
-+How to build
-+============
-+Configure Weston with --enable-surface-remoting to build the Transmitter
-+plugin.
-+
-+How to write weston.ini
-+=======================
-+To load transmitter plugin to weston, add 'transmitter.so' to the 'modules'
-+key under '[core]', and make sure the 'shell' is 'ivi-shell.so'.
-+
-+The destination of remoting is configured in weston.ini.
-+Add output name, server address, port number, output's width and height key
-+under '[remote-output]'.
-+You can speficy multiple [remote-output].
-+
-+In details, see 'weston.ini.transmitter'.
-+
-+How to test
-+===========
-+You can use server side test application in waltham-server directory.
-+
-+If you set 'WALTHAM_DEBUG=1' to your environment valuable, you can
-+see the log like this:

-+ * The client calls wl_seat.get_pointer. => send enter only on the new

-+ *
-+ * 3. Client has wl_pointer. Transmitter seat adds pointer capability.
-+ * Transmitter receives pointer.enter. wl_pointer MUST NOT enter,
-+ * specified by wl_seat.capabilities.
-+ *
-+ * By definition, Transmitter cannot receive pointer.enter without having
-+ * pointer capability in the seat, so no other combinations are possible.
-+ *
-+ * The same applies to wl_keyboard and wl_touch.
-+ */
-+
-+/* Implementor notes:
-+ *
-+ * The handling of all of wl_pointer, wl_keyboard and wl_touch should be
-+ * similar. To make it work, we need to add a signal to each of the
-+ * wl_seat.get_pointer, wl_seat.get_keyboard, and wl_seat.get_touch request
-+ * handlers in Weston core. Otherwise we cannot implement the case 2 of gaining
-+ * input device focus.
-+ *
-+ * However, weston_keyboard::focus is a weston_surface, not a weston_view, so
-+ * we may be able to leverage more of the core implementation and maybe do
-+ * without the wl_seat.get_keyboard signal. Weston_touch uses a weston_view, so
-+ * that is similar to weston_pointer.
-+ *
-+ * It might be useful to convert weston_keyboard and weston_touch to use a
-+ * similar thing as weston_pointer_client, in case it makes things more
-+ * consistent. It might also fix issues when a client has multiple copies of a
-+ * wl_keyboard or a wl_touch, but that is getting off-topic.
-+ *
-+ * This file shows which part of the Weston input path we skip and where we
-+ * hook in. We skip everything starting from the notify_*() API used by
-+ * backends, and stub out the grab handlers. Instead of actual grab handlers,
-+ * we have our own network protocol events handlers. They do much of the same
-+ * as normal grab handlers would do, except focus is pre-given, and we do not
-+ * have weston_view for the focus surfaces, so we need to bypass core code
-+ * dealing with those.
-+ *
-+ * Our remote seat implementation will leave many struct members unused and
-+ * replicate some from weston_pointer, weston_keyboard, and weston_touch.
-+ * Weston core must be kept out from the focus handling business, because we
-+ * will send enter/leave events ourselves, and focus assignments are given
-+ * to us from the remote, they cannot be changed at will by the local Weston.
-+ */
-+
-+/** Callback from the protocol request handler for wl_seat.get_pointer
-+ *
-+ * The Weston core handler never sees focus set on the weston_pointer,
-+ * so it won't send wl_pointer.enter nor set focus_client. It does call
-+ * weston_pointer_ensure_pointer_client() though.

-+ * This is an implementation of a remote output.
-+ *
-+ * A remote output must not be accepted as an argument to:
-+ * - wl_shell_surface.set_fullscreen
-+ * - wl_shell_surface.set_maximized
-+ * - zwp_fullscreen_shell_v1.present_surface
-+ * - zwp_fullscreen_shell_v1.present_surface_for_mode
-+ * - zwp_input_panel_surface_v1.set_toplevel
-+ * - xdg_surface.set_fullscreen
-+ *
-+ * If a remote output is an argument to the above or similar requests,
-+ * it should have the same effect as NULL if possible.
-+ *
-+ * @todo Should we instead accept the argument and have it start remoting
-+ * automatically? That would be shell-specific.
-+ *
-+ * In ivi-shell's case, only zwp_input_panel_surface_v1.set_toplevel is
-+ * reachable from keyboard.c. That just blindly uses whatever the first
-+ * output happens to be, so there is no need to check for now.
-+ *
-+ * @todo Add weston_output_set_remote() which sets weston_output::is_remote
-+ * to true and inits weston_output::link. This should be made mutually
-+ * exclusive with weston_compositor_add_output().
