SDL_SetAssertionHandler - Set an application-defined assertion handler.

       This function is available since SDL 3.2.0.

       This  function  allows  an  application  to  show  its  own  assertion UI and/or force the response to an
       assertion failure. If the application doesn't provide this, SDL will try to do the right  thing,  popping
       up a system-specific GUI dialog, and probably minimizing any fullscreen windows.

       This  callback  may  fire  from any thread, but it runs wrapped in a mutex, so it will only fire from one
       thread at a time.

       This callback is NOT reset to SDL's internal handler upon

       SDL_Quit ()!
