*
* 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().
*
* Simple rumble example:
*
* 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 );
*
*
* Complete example:
*
* 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
* 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

* - SDL_HAPTIC_SPHERICAL : Specified by spherical coordinates.
*
* Cardinal directions of the haptic device are relative to the positioning

*
* 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 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 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 dir parameters are used. The 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).
*
*
* Example of force coming from the south with all encodings (force coming
* from the south means the user will have to pull the stick to counteract):
*
* SDL_HapticDirection direction;
*
* // Cartesian directions
* direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
* direction.dir[0] = 0; // X position
* direction.dir[1] = 1; // Y position
* // Assuming the device has 2 axes, we don't need to specify third parameter.
*
* // Polar directions
* direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding.
* direction.dir[0] = 18000; // Polar only uses first parameter
*
* // Spherical coordinates
* direction.type = SDL_HAPTIC_SPHERICAL; // Spherical encoding
* direction.dir[0] = 9000; // Since we only have two axes we don't need more parameters.

*
* 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 cycle 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.

* All values max at 32767 (0x7FFF). Signed values also can be negative.

*
* 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:
*
* // 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.
