60 * @brief Initializes the thread controller
62 * Will do any required initialiszation, e.g. initialize EGL, create threads (if required), etc.
64 * @note When this function returns, the application Init signal should be emitted
69 * @brief Called AFTER the Init signal has been emitted.
71 * In other words, should be called AFTER the Init signal has been emitted and all messages for the first scene
72 * have been queued for update to process.
77 * @brief When called, update and rendering is paused.
82 * @brief Resumes update/rendering after a previous pause.
87 * @brief Stops update/rendering altogether.
89 * Will shutdown EGL, destroy threads (if required) etc.
94 * @brief Called by the adaptor when core requires another update
99 * @brief Called by the adaptor when core requires one update
