/**
 *  \file SDL_input.h
 *  
 *  Include file for lowlevel SDL input device handling.
 *
 *  This talks about individual devices, and not the system cursor. If you
 *  just want to know when the user moves the pointer somewhere in your
 *  window, this is NOT the API you want. This one handles things like
 *  multi-touch, drawing tablets, and multiple, separate mice.
 *
 *  The other API is in SDL_mouse.h
