// in either the upper left, lower right, or center and then have them
// press a key or button and then call the appropriate one of these
// routines, and it will read the stick and update the calibration factors.
// Usually, assuming that the stick was centered when joy_init was

// left position is usually always 0,0 on most joys. But, the safest
