+ *  \file SDL_haptic.h
+ *
+ *  \brief The SDL haptic subsystem allows you to control haptic (force feedback)
+ *         devices.
+ *
+ *  The basic usage is as follows:
+ *   - Initialize the subsystem (::SDL_INIT_HAPTIC).
+ *   - Open a haptic device.
+ *    - SDL_HapticOpen() to open from index.
+ *    - SDL_HapticOpenFromJoystick() to open from an existing joystick.
+ *   - Create an effect (::SDL_HapticEffect).
+ *   - Upload the effect with SDL_HapticNewEffect().
+ *   - Run the effect with SDL_HapticRunEffect().
+ *   - (optional) Free the effect with SDL_HapticDestroyEffect().
+ *   - Close the haptic device with SDL_HapticClose().
+ *
+ * \par Simple rumble example:
+ * \code
+ *    SDL_Haptic *haptic;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpen( 0 );
+ *    if (haptic == NULL)
+ *       return -1;
+ *
+ *    // Initialize simple rumble
+ *    if (SDL_HapticRumbleInit( haptic ) != 0)
+ *       return -1;
+ *
+ *    // Play effect at 50% strength for 2 seconds
+ *    if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
+ *       return -1;
+ *    SDL_Delay( 2000 );
+ *
+ *    // Clean up
+ *    SDL_HapticClose( haptic );
+ * \endcode
+ *
+ * \par Complete example:
+ * \code
+ * int test_haptic( SDL_Joystick * joystick ) {
+ *    SDL_Haptic *haptic;
+ *    SDL_HapticEffect effect;
+ *    int effect_id;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpenFromJoystick( joystick );
+ *    if (haptic == NULL) return -1; // Most likely joystick isn't haptic
+ *
+ *    // See if it can do sine waves
+ *    if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
+ *       SDL_HapticClose(haptic); // No sine effect
+ *       return -1;
+ *    }
+ *
+ *    // Create the effect
+ *    SDL_memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
+ *    effect.type = SDL_HAPTIC_SINE;
+ *    effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ *    effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ *    effect.periodic.period = 1000; // 1000 ms
+ *    effect.periodic.magnitude = 20000; // 20000/32767 strength
+ *    effect.periodic.length = 5000; // 5 seconds long
+ *    effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ *    effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ *    // Upload the effect
+ *    effect_id = SDL_HapticNewEffect( haptic, &effect );
+ *
+ *    // Test the effect
+ *    SDL_HapticRunEffect( haptic, effect_id, 1 );
+ *    SDL_Delay( 5000); // Wait for the effect to finish
+ *
+ *    // We destroy the effect, although closing the device also does this
+ *    SDL_HapticDestroyEffect( haptic, effect_id );
+ *
+ *    // Close the device
+ *    SDL_HapticClose(haptic);
+ *
+ *    return 0; // Success
+ * }
+ * \endcode

+ *  If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ *  degree starting north and turning clockwise.  ::SDL_HAPTIC_POLAR only uses
+ *  the first \c dir parameter.  The cardinal directions would be:
+ *   - North: 0 (0 degrees)
+ *   - East: 9000 (90 degrees)
+ *   - South: 18000 (180 degrees)
+ *   - West: 27000 (270 degrees)
+ *
+ *  If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ *  (X axis, Y axis and Z axis (with 3 axes)).  ::SDL_HAPTIC_CARTESIAN uses
+ *  the first three \c dir parameters.  The cardinal directions would be:
+ *   - North:  0,-1, 0
+ *   - East:   1, 0, 0
+ *   - South:  0, 1, 0
+ *   - West:  -1, 0, 0
+ *
+ *  The Z axis represents the height of the effect if supported, otherwise
+ *  it's unused.  In cartesian encoding (1, 2) would be the same as (2, 4), you
+ *  can use any multiple you want, only the direction matters.
+ *
+ *  If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ *  The first two \c dir parameters are used.  The \c dir parameters are as
+ *  follows (all values are in hundredths of degrees):
+ *   - Degrees from (1, 0) rotated towards (0, 1).
+ *   - Degrees towards (0, 0, 1) (device needs at least 3 axes).

+ *
+ *  A periodic effect consists in a wave-shaped effect that repeats itself
+ *  over time.  The type determines the shape of the wave and the parameters
+ *  determine the dimensions of the wave.
+ *
+ *  Phase is given by hundredth of a degree meaning that giving the phase a value
+ *  of 9000 will displace it 25% of its period.  Here are sample values:
+ *   -     0: No phase displacement.
+ *   -  9000: Displaced 25% of its period.
+ *   - 18000: Displaced 50% of its period.
+ *   - 27000: Displaced 75% of its period.
+ *   - 36000: Displaced 100% of its period, same as 0, but 0 is preferred.

+ *  All values max at 32767 (0x7FFF).  Signed values also can be negative.
+ *  Time values unless specified otherwise are in milliseconds.
+ *
+ *  You can also pass ::SDL_HAPTIC_INFINITY to length instead of a 0-32767
+ *  value.  Neither delay, interval, attack_length nor fade_length support
+ *  ::SDL_HAPTIC_INFINITY.  Fade will also not be used since effect never ends.
+ *
+ *  Additionally, the ::SDL_HAPTIC_RAMP effect does not support a duration of
+ *  ::SDL_HAPTIC_INFINITY.
+ *
+ *  Button triggers may not be supported on all devices, it is advised to not
+ *  use them if possible.  Buttons start at index 1 instead of index 0 like
+ *  the joystick.
+ *
+ *  If both attack_length and fade_level are 0, the envelope is not used,
+ *  otherwise both values are used.
+ *
+ *  Common parts:
+ *  \code
+ *  // Replay - All effects have this
+ *  Uint32 length;        // Duration of effect (ms).
+ *  Uint16 delay;         // Delay before starting effect.
+ *
+ *  // Trigger - All effects have this
+ *  Uint16 button;        // Button that triggers effect.
+ *  Uint16 interval;      // How soon before effect can be triggered again.
+ *
+ *  // Envelope - All effects except condition effects have this
+ *  Uint16 attack_length; // Duration of the attack (ms).
+ *  Uint16 attack_level;  // Level at the start of the attack.
+ *  Uint16 fade_length;   // Duration of the fade out (ms).
+ *  Uint16 fade_level;    // Level at the end of the fade.
