Get the current state of an axis control on a joystick.
SDL makes no promises about what part of the joystick any given axis refers
to. Your game should have some sort of configuration UI to let users
specify what each axis should be bound to. Alternately, SDL's higher-level
Game Controller API makes a great effort to apply order to this lower-level
interface, so you know that a specific axis is the "left thumb stick," etc.
The value returned by SDL_GetJoystickAxis() is a signed integer (-32768 to
32767) representing the current position of the axis. It may be necessary
to impose certain tolerances on these values to account for jitter.
