+ *
+ * wl_display_get_registry() sends a request to the server, to which
+ * the server replies by emitting the wl_registry.global events.
+ * The first wl_display_roundtrip() sends wl_display.sync. The server
+ * first processes the wl_display.get_registry which includes sending
+ * the global events, and then processes the sync. Therefore when the
+ * sync (roundtrip) returns, we are guaranteed to have received and
+ * processed all the global events.
+ *
+ * While we are inside the first wl_display_roundtrip(), incoming
+ * events are dispatched, which causes registry_handle_global() to
+ * be called for each global. One of these globals is wl_shm.
+ * registry_handle_global() sends wl_registry.bind request for the
+ * wl_shm global. However, wl_registry.bind request is sent after
+ * the first wl_display.sync, so the reply to the sync comes before
+ * the initial events of the wl_shm object.
+ *
+ * The initial events that get sent as a reply to binding to wl_shm
+ * include wl_shm.format. These tell us which pixel formats are
+ * supported, and we need them before we can create buffers. They
+ * don't change at runtime, so we receive them as part of init.
+ *
+ * When the reply to the first sync comes, the server may or may not
+ * have sent the initial wl_shm events. Therefore we need the second
+ * wl_display_roundtrip() call here.
+ *
+ * The server processes the wl_registry.bind for wl_shm first, and
+ * the second wl_display.sync next. During our second call to
+ * wl_display_roundtrip() the initial wl_shm events are received and
+ * processed. Finally, when the reply to the second wl_display.sync
+ * arrives, it guarantees we have processed all wl_shm initial events.
+ *
+ * This sequence contains two examples on how wl_display_roundtrip()
+ * can be used to guarantee, that all reply events to a request
+ * have been received and processed. This is a general Wayland
+ * technique.
