+/*! Panel state management.
+ *
+ * This is effectively a mirror of the previous C code,
+ * with an explicit state machine managing the panel size.
+ *
+ * It still relies on a callback from Wayland to accept the panel size,
+ * which makes this code somewhat prone to mistakes.
+ *
+ * An alternative to the callback would be
+ * to send a message all the way to `state::State`
+ * every time the allocated size changes.
+ * That would allow for a more holistic view
+ * of interactions of different pieces of state.
+ * 
+ * However, `state::State` already has the potential to become a ball of mud,
+ * tightly coupling different functionality and making it difficult to see independent units.
+ * 
+ * For this reason, I'm taking a light touch approach with the panel manager,
+ * and moving it just a bit closer to `state::State`.
+ * Hopefully ths still allows us to expose assumptions that were not stated yet
+ * (e.g. can the output disappear between size request andallocation?).
+ *
+ * Tight coupling, e.g. a future one between presented hints and layout size,
+ * will have to be taken into account later.
