SDL_PumpEvents - Pump the event loop, gathering events from the input devices.

       This function is available since SDL 3.2.0.

       This function updates the event queue and internal input device state.

       SDL_PumpEvents() gathers all the pending input information from devices and places it in the event queue.
       Without  calls  to SDL_PumpEvents() no events would ever be placed on the queue. Often the need for calls
       to SDL_PumpEvents() is hidden from the user since SDL_PollEvent()  and  SDL_WaitEvent()  implicitly  call
       SDL_PumpEvents().   However,  if you are not polling or waiting for events (e.g. you are filtering them),
       then you must call SDL_PumpEvents() to force an event queue update.
