246 /*! \brief The backend engine mb_backend_t is used to define the interface to realize the MB.
247 *
248 * A backend is used to receive events from the system. The MB does not define the backend by itself.
249 * Instead, it define an interface which allow the lower layer to implement the event system. Each
250 * backend need to provides the following events.
251 *
252 * - keyboard event
253 * - timer event
254 * - image loader(?)
255 * - render manager(?)
