+(b) for infringements caused by: (i) Your and any other third party's
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+ its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+ Form, as described in Section 3.1, and You must inform recipients of
+ the Executable Form how they can obtain a copy of such Source Code
+ Form by reasonable means in a timely manner, at a charge no more
+ than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter
+ the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.
+
+************************************************************************
+* *
+* 6. Disclaimer of Warranty *
+* ------------------------- *
+* *
+* Covered Software is provided under this License on an "as is" *
+* basis, without warranty of any kind, either expressed, implied, or *
+* statutory, including, without limitation, warranties that the *
+* Covered Software is free of defects, merchantable, fit for a *
+* particular purpose or non-infringing. The entire risk as to the *
+* quality and performance of the Covered Software is with You. *
+* Should any Covered Software prove defective in any respect, You *
+* (not any Contributor) assume the cost of any necessary servicing, *
+* repair, or correction. This disclaimer of warranty constitutes an *
+* essential part of this License. No use of any Covered Software is *
+* authorized under this License except under this disclaimer. *
+* *
+************************************************************************
+
+************************************************************************
+* *
+* 7. Limitation of Liability *
+* -------------------------- *
+* *
+* Under no circumstances and under no legal theory, whether tort *
+* (including negligence), contract, or otherwise, shall any *
+* Contributor, or anyone who distributes Covered Software as *
+* permitted above, be liable to You for any direct, indirect, *
+* special, incidental, or consequential damages of any character *
+* including, without limitation, damages for lost profits, loss of *
+* goodwill, work stoppage, computer failure or malfunction, or any *
+* and all other commercial damages or losses, even if such party *
+* shall have been informed of the possibility of such damages. This *
+* limitation of liability shall not apply to liability for death or *
+* personal injury resulting from such party's negligence to the *
+* extent applicable law prohibits such limitation. Some *
+* jurisdictions do not allow the exclusion or limitation of *
+* incidental or consequential damages, so this exclusion and *
+* limitation may not apply to You. *
+* *
+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the
+notice described in Exhibit B of this License must be attached.

+ {* Register a special effect function. At mixing time, the channel data is
+ * copied into a buffer and passed through each registered effect function.
+ * After it passes through all the functions, it is mixed into the final
+ * output stream. The copy to buffer is performed once, then each effect
+ * function performs on the output of the previous effect. Understand that
+ * this extra copy to a buffer is not performed if there are no effects
+ * registered for a given chunk, which saves CPU cycles, and any given
+ * effect will be extra cycles, too, so it is crucial that your code run
+ * fast. Also note that the data that your function is given is in the
+ * format of the sound device, and not the format you gave to Mix_OpenAudio(),
+ * although they may in reality be the same. This is an unfortunate but
+ * necessary speed concern. Use Mix_QuerySpec() to determine if you can
+ * handle the data before you register your effect, and take appropriate
+ * actions.
+ * You may also specify a callback (Mix_EffectDone_t) that is called when
+ * the channel finishes playing. This gives you a more fine-grained control
+ * than Mix_ChannelFinished(), in case you need to free effect-specific
+ * resources, etc. If you don't need this, you can specify NULL.
+ * You may set the callbacks before or after calling Mix_PlayChannel().
+ * Things like Mix_SetPanning() are just internal special effect functions,
+ * so if you are using that, you've already incurred the overhead of a copy
+ * to a separate buffer, and that these effects will be in the queue with
+ * any functions you've registered. The list of registered effects for a
+ * channel is reset when a chunk finishes playing, so you need to explicitly
+ * set them with each call to Mix_PlayChannel*().
+ * You may also register a special effect function that is to be run after
+ * final mixing occurs. The rules for these callbacks are identical to those

+ * music have been mixed into a single stream, whereas channel-specific
+ * effects run on a given channel before any other mixing occurs. These
+ * global effect callbacks are call "posteffects". Posteffects only have
+ * their Mix_EffectDone_t function called when they are unregistered (since
+ * the main output stream is never "done" in the same sense as a channel).
+ * You must unregister them manually when you've had enough. Your callback
+ * will be told that the channel being mixed is (MIX_CHANNEL_POST) if the
+ * processing is considered a posteffect.

+ * 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

+ * If type is SDL_HAPTIC_POLAR, direction is encoded by hundredths of a

+ * - 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).

+ *
+ * // 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.
