   * \brief Translates SDL events into \c QJoysticks events
   *
   * This class is in charge of managing and operating real joysticks through the
   * SDL API. The implementation procedure is the same for every operating system.
   *
   * The only thing that differs from each operating system is the backup mapping
   * applied in the case that we do not know what mapping to apply to a joystick.
   *
   * \note The joystick values are refreshed every 20 milliseconds through a
   *       simple event loop.
