* read each event from that queue inside SDL_ANDROID_PumpEvents(),
* unlock the mutex, and push the event to SDL queue,
* which is then immediately read by SDL from the same thread,
* and then SDL invokes event filter function from FHeroes2.
* FHeroes2 call SDL_Flip() from inside that event filter function,
