SDL_PenProximityEvent - Pressure-sensitive pen proximity event structure (event.pmotion.*)

       This struct is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                       SDL_PenProximityEvent(3type)

       When a pen becomes visible to the system (it is close enough to a tablet, etc), SDL will send an

       SDL_EVENT_PEN_PROXIMITY_IN
        event  with  the  new  pen's ID. This ID is valid until the pen leaves proximity again (has been removed
       from the tablet's area, the tablet has been unplugged, etc). If the same pen reenters proximity again, it
       will be given a new ID.

       Note that "proximity" means "close enough for the tablet to know the tool is there." The pen touching and
       lifting off from the tablet while not leaving the area are handled by SDL_EVENT_PEN_DOWN

       and SDL_EVENT_PEN_UP .
