+/**
+ * ClientInit
+ *
+ * Once the client and server are sure that they're happy to talk to one
+ * another, the client sends an initialisation message.  At present this
+ * message onl@!,@!,y consists of a boolean indicating whether the server should try
+ * to share the desktop by leaving other clients connected, or give exclusive
+ * access to this client by disconnecting all other clients.
+ *
+ * 1 - U8 - shared-flag
+ *
+ * Shared-flag is non-zero (true) if the server should try to share the desktop by leaving
+ * other clients connected, zero (false) if it should give exclusive access to this client by
+ * disconnecting all other clients.
+ *
+ * ServerInit
+ *
+ * After receiving the ClientInit message, the server sends a ServerInit message. This
+ * tells the client the width and height of the server’s framebuffer, its pixel format and the
+ * name associated with the desktop.
