* firing off a few values throughout this range (these joysticks will
* tend to rest at 0) whilst a truly analogue joystick will fire lots
* of different values with the middle firing anything but 0. The
* JOYDEADZONE offers us a reasonable user configurable middle region.
*
* To simulate digital on/off button functionality from an analogue
* axis we need to record previous axis motion activity so that we can
* see if we've already generated an SDL_JOYBUTTONDOWN/UP event. This
* activity is stored within the axisstates array as pairs of values
* representing both ends of an axis, with each value belonging to a
* virtual button. The first integer records the up/down state of the
* negative end of an axis with the positive end stored in the other.
*
* Following are the situations that this code will account for :-
* SDL_JOYBUTTONDOWN - axis middle to any axis end
* SDL_JOYBUTTONDOWN - one axis end to another axis end with the
* opposite end generating SDL_JOYBUTTONUP
* SDL_JOYBUTTONUP - any axis end to the middle */
