SDL_SetModState - Set the current key modifier state for the keyboard.

       This function is available since SDL 3.2.0.

       The  inverse  of  SDL_GetModState(),  SDL_SetModState()  allows you to impose modifier key states on your
       application. Simply pass your desired modifier states into modstate.  This value may be a  bitwise,  OR'd
       combination of SDL_Keymod values.

       This does not change the keyboard state, only the key modifier flags that SDL reports.
