+ *
+ * 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.
