- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
- The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users. We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors. You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
- To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. You must make sure that they, too, receive
-or can get the source code. And you must show them these terms so they
-know their rights.
-
- Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
- For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
- Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so. This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software. The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable. Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products. If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
- Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary. To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS
-
- 0. Definitions.
-
- "This License" refers to version 3 of the GNU General Public License.
-
- "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
- "The Program" refers to any copyrightable work licensed under this
-License. Each licensee is addressed as "you". "Licensees" and
-"recipients" may be individuals or organizations.
-
- To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy. The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
- A "covered work" means either the unmodified Program or a work based
-on the Program.
-
- To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
- To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies. Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
- An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License. If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
- 1. Source Code.
-
- The "source code" for a work means the preferred form of the work
-for making modifications to it. "Object code" means any non-source
-form of a work.
-
- A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
- The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form. A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
- The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities. However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work. For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
- The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
- The Corresponding Source for a work in source code form is that
-same work.
-
- 2. Basic Permissions.
-
- All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met. This License explicitly affirms your unlimited
-permission to run the unmodified Program. The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work. This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
- You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force. You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright. Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
- Conveying under any other circumstances is permitted solely under
-the conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-
- 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
- No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
- When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
- 4. Conveying Verbatim Copies.
-
- You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
- You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
- 5. Conveying Modified Source Versions.
-
- You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
- a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.
-
- b) The work must carry prominent notices stating that it is
- released under this License and any conditions added under section
- 7. This requirement modifies the requirement in section 4 to
- "keep intact all notices".
-
- c) You must license the entire work, as a whole, under this
- License to anyone who comes into possession of a copy. This
- License will therefore apply, along with any applicable section 7
- additional terms, to the whole of the work, and all its parts,
- regardless of how they are packaged. This License gives no
- permission to license the work in any other way, but it does not
- invalidate such permission if you have separately received it.
-
- d) If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your
- work need not make them do so.
-
- A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit. Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
- 6. Conveying Non-Source Forms.
-
- You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
- a) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by the
- Corresponding Source fixed on a durable physical medium
- customarily used for software interchange.
-
- b) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by a
- written offer, valid for at least three years and valid for as
- long as you offer spare parts or customer support for that product
- model, to give anyone who possesses the object code either (1) a
- copy of the Corresponding Source for all the software in the
- product that is covered by this License, on a durable physical
- medium customarily used for software interchange, for a price no
- more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the
- Corresponding Source from a network server at no charge.
-
- c) Convey individual copies of the object code with a copy of the
- written offer to provide the Corresponding Source. This
- alternative is allowed only occasionally and noncommercially, and
- only if you received the object code with such an offer, in accord
- with subsection 6b.
-
- d) Convey the object code by offering access from a designated
- place (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to
- copy the object code is a network server, the Corresponding Source
- may be on a different server (operated by you or a third party)
- that supports equivalent copying facilities, provided you maintain
- clear directions next to the object code saying where to find the
- Corresponding Source. Regardless of what server hosts the
- Corresponding Source, you remain obligated to ensure that it is
- available for as long as needed to satisfy these requirements.
-
- e) Convey the object code using peer-to-peer transmission, provided
- you inform other peers where the object code and Corresponding
- Source of the work are being offered to the general public at no
- charge under subsection 6d.
-
- A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
- A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling. In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage. For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product. A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
- "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source. The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
- If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information. But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
- The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed. Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
- Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
- 7. Additional Terms.
-
- "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law. If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
- When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it. (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.) You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
- Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
- a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- b) Requiring preservation of specified reasonable legal notices or
- author attributions in that material or in the Appropriate Legal
- Notices displayed by works containing it; or
-
- c) Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
-
- d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
-
- e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- f) Requiring indemnification of licensors and authors of that
- material by anyone who conveys the material (or modified versions of
- it) with contractual assumptions of liability to the recipient, for
- any liability that these contractual assumptions directly impose on
- those licensors and authors.
-
- All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10. If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term. If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
- If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
- Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
- 8. Termination.
-
- You may not propagate or modify a covered work except as expressly
-provided under this License. Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
- However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
- Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
- 9. Acceptance Not Required for Having Copies.
-
- You are not required to accept this License in order to receive or
-run a copy of the Program. Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance. However,
-nothing other than this License grants you permission to propagate or
-modify any covered work. These actions infringe copyright if you do
-not accept this License. Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
- 10. Automatic Licensing of Downstream Recipients.
-
- Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License. You are not responsible
-for enforcing compliance by third parties with this License.
-
- An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations. If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
- You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License. For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
- 11. Patents.
-
- A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based. The
-work thus licensed is called the contributor's "contributor version".
-
- A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version. For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
- Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
- In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement). To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
- If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients. "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
- If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
- A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License. You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
- Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
- 12. No Surrender of Others' Freedom.
-
- If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all. For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
- 13. Use with the GNU Affero General Public License.
-
- Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work. The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
- 14. Revised Versions of this License.
-
- The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation. If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
- If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
- Later license versions may give you additional or different
-permissions. However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
- 15. Disclaimer of Warranty.
-
- THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. Limitation of Liability.
-
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
- 17. Interpretation of Sections 15 and 16.
-
- If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation, either version 3 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ * The file I/O (for example: SDL_RWFromFile) and threading (SDL_CreateThread)

+ * - `SDL_INIT_AUDIO`: audio subsystem
+ * - `SDL_INIT_VIDEO`: video subsystem; automatically initializes the events

+ * - `SDL_INIT_JOYSTICK`: joystick subsystem; automatically initializes the

+ * - `SDL_INIT_GAMECONTROLLER`: controller subsystem; automatically
+ * initializes the joystick subsystem
+ * - `SDL_INIT_EVENTS`: events subsystem
+ * - `SDL_INIT_EVERYTHING`: all of the above subsystems
+ * - `SDL_INIT_NOPARACHUTE`: compatibility; this flag is ignored

- * - \c desired->samples is the desired size of the audio buffer, in

- * the audio driver to a value more suitable for the hardware. Good values
- * seem to range between 512 and 8096 inclusive, depending on the
- * application and CPU speed. Smaller values yield faster response time,
- * but can lead to underflow if the application is doing heavy processing
- * and cannot fill the audio buffer in time. A stereo sample consists of
- * both right and left channels in LR ordering.
- * Note that the number of samples is directly related to time by the
- * following formula: \code ms = (samples*1000)/freq \endcode
- * - \c desired->size is the size in bytes of the audio buffer, and is
- * calculated by SDL_OpenAudio().
- * - \c desired->silence is the value used to set the buffer to silence,
- * and is calculated by SDL_OpenAudio().
- * - \c desired->callback should be set to a function that will be called
- * when the audio device is ready for more data. It is passed a pointer
- * to the audio buffer, and the length in bytes of the audio buffer.
- * This function usually runs in a separate thread, and so you should
- * protect data structures that it accesses by calling SDL_LockAudio()
- * and SDL_UnlockAudio() in your code. Alternately, you may pass a NULL
- * pointer here, and call SDL_QueueAudio() with some frequency, to queue
- * more audio samples to be played (or for capture devices, call
- * SDL_DequeueAudio() with some frequency, to obtain audio samples).
- * - \c desired->userdata is passed as the first parameter to your callback
- * function. If you passed a NULL callback, this value is ignored.
+ * This function remains for compatibility with SDL 1.2, but also because it's
+ * slightly easier to use than the new functions in SDL 2.0. The new, more
+ * powerful, and preferred way to do this is SDL_OpenAudioDevice().
*
- * The audio device starts out playing silence when it's opened, and should
- * be enabled for playing by calling \c SDL_PauseAudio(0) when you are ready
- * for your audio callback function to be called. Since the audio driver
- * may modify the requested size of the audio buffer, you should allocate
- * any local mixing buffers after you open the audio device.
+ * This function is roughly equivalent to:
+ *
+ * ```c
+ * SDL_OpenAudioDevice(NULL, 0, desired, obtained, SDL_AUDIO_ALLOW_ANY_CHANGE);
+ * ```
+ *
+ * With two notable exceptions:
+ *
+ * - If `obtained` is NULL, we use `desired` (and allow no changes), which
+ * means desired will be modified to have the correct values for silence,
+ * etc, and SDL will convert any differences between your app's specific
+ * request and the hardware behind the scenes.
+ * - The return value is always success or failure, and not a device ID, which
+ * means you can only have one device open at a time with this function.

+ * Passing in a `device` name of NULL requests the most reasonable default
+ * (and is equivalent to what SDL_OpenAudio() does to choose a device). The

+ * some drivers allow arbitrary and driver-specific strings, such as a
+ * hostname/IP address for a remote audio server, or a filename in the
+ * diskaudio driver.
+ *
+ * An opened audio device starts out paused, and should be enabled for playing
+ * by calling SDL_PauseAudioDevice(devid, 0) when you are ready for your audio
+ * callback function to be called. Since the audio driver may modify the
+ * requested size of the audio buffer, you should allocate any local mixing
+ * buffers after you open the audio device.
+ *
+ * The audio callback runs in a separate thread in most cases; you can prevent
+ * race conditions between your callback and other threads without fully
+ * pausing playback with SDL_LockAudioDevice(). For more information about the
+ * callback, see SDL_AudioSpec.
+ *
+ * Managing the audio spec via 'desired' and 'obtained':
+ *
+ * When filling in the desired audio spec structure:
+ *
+ * - `desired->freq` should be the frequency in sample-frames-per-second (Hz).
+ * - `desired->format` should be the audio format (`AUDIO_S16SYS`, etc).
+ * - `desired->samples` is the desired size of the audio buffer, in _sample
+ * frames_ (with stereo output, two samples--left and right--would make a
+ * single sample frame). This number should be a power of two, and may be
+ * adjusted by the audio driver to a value more suitable for the hardware.
+ * Good values seem to range between 512 and 8096 inclusive, depending on
+ * the application and CPU speed. Smaller values reduce latency, but can
+ * lead to underflow if the application is doing heavy processing and cannot
+ * fill the audio buffer in time. Note that the number of sample frames is
+ * directly related to time by the following formula: `ms =
+ * (sampleframes*1000)/freq`
+ * - `desired->size` is the size in _bytes_ of the audio buffer, and is
+ * calculated by SDL_OpenAudioDevice(). You don't initialize this.
+ * - `desired->silence` is the value used to set the buffer to silence, and is
+ * calculated by SDL_OpenAudioDevice(). You don't initialize this.
+ * - `desired->callback` should be set to a function that will be called when
+ * the audio device is ready for more data. It is passed a pointer to the
+ * audio buffer, and the length in bytes of the audio buffer. This function
+ * usually runs in a separate thread, and so you should protect data
+ * structures that it accesses by calling SDL_LockAudioDevice() and
+ * SDL_UnlockAudioDevice() in your code. Alternately, you may pass a NULL
+ * pointer here, and call SDL_QueueAudio() with some frequency, to queue
+ * more audio samples to be played (or for capture devices, call
+ * SDL_DequeueAudio() with some frequency, to obtain audio samples).
+ * - `desired->userdata` is passed as the first parameter to your callback
+ * function. If you passed a NULL callback, this value is ignored.
+ *
+ * `allowed_changes` can have the following flags OR'd together:
+ *
+ * - `SDL_AUDIO_ALLOW_FREQUENCY_CHANGE`
+ * - `SDL_AUDIO_ALLOW_FORMAT_CHANGE`
+ * - `SDL_AUDIO_ALLOW_CHANNELS_CHANGE`
+ * - `SDL_AUDIO_ALLOW_ANY_CHANGE`
+ *
+ * These flags specify how SDL should behave when a device cannot offer a
+ * specific feature. If the application requests a feature that the hardware
+ * doesn't offer, SDL will always try to get the closest equivalent.
+ *
+ * For example, if you ask for float32 audio format, but the sound card only
+ * supports int16, SDL will set the hardware to int16. If you had set
+ * SDL_AUDIO_ALLOW_FORMAT_CHANGE, SDL will change the format in the `obtained`
+ * structure. If that flag was *not* set, SDL will prepare to convert your
+ * callback's float32 audio to int16 before feeding it to the hardware and
+ * will keep the originally requested format in the `obtained` structure.
+ *
+ * The resulting audio specs, varying depending on hardware and on what
+ * changes were allowed, will then be written back to `obtained`.
+ *
+ * If your application can only handle one specific data format, pass a zero
+ * for `allowed_changes` and let SDL transparently handle any differences.
+ *
+ * \param device a UTF-8 string reported by SDL_GetAudioDeviceName() or a
+ * driver-specific name as appropriate. NULL requests the most
+ * reasonable default device.
+ * \param iscapture non-zero to specify a device should be opened for
+ * recording, not playback
+ * \param desired an SDL_AudioSpec structure representing the desired output
+ * format; see SDL_OpenAudio() for more information

- * \param dstColorFactor destination color factor
- * \param colorOperation color operation
- * \param srcAlphaFactor source alpha factor
- * \param dstAlphaFactor destination alpha factor
- * \param alphaOperation alpha operation
+ * The functions SDL_SetRenderDrawBlendMode and SDL_SetTextureBlendMode accept
+ * the SDL_BlendMode returned by this function if the renderer supports it.
*
- * The result of the blend mode operation will be:
- * dstRGB = dstRGB * dstColorFactor colorOperation srcRGB * srcColorFactor
- * and
- * dstA = dstA * dstAlphaFactor alphaOperation srcA * srcAlphaFactor
+ * A blend mode controls how the pixels from a drawing operation (source) get
+ * combined with the pixels from the render target (destination). First, the
+ * components of the source and destination pixels get multiplied with their
+ * blend factors. Then, the blend operation takes the two products and
+ * calculates the result that will get stored in the render target.
+ *
+ * Expressed in pseudocode, it would look like this:
+ *
+ * ```c
+ * dstRGB = colorOperation(srcRGB * srcColorFactor, dstRGB * dstColorFactor);
+ * dstA = alphaOperation(srcA * srcAlphaFactor, dstA * dstAlphaFactor);
+ * ```
+ *
+ * Where the functions `colorOperation(src, dst)` and `alphaOperation(src,
+ * dst)` can return one of the following:
+ *
+ * - `src + dst`
+ * - `src - dst`
+ * - `dst - src`
+ * - `min(src, dst)`
+ * - `max(src, dst)`
+ *
+ * The red, green, and blue components are always multiplied with the first,
+ * second, and third components of the SDL_BlendFactor, respectively. The
+ * fourth component is not used.
+ *
+ * The alpha component is always multiplied with the fourth component of the
+ * SDL_BlendFactor. The other components are not used in the alpha
+ * calculation.
+ *
+ * Support for these blend modes varies for each renderer. To check if a
+ * specific SDL_BlendMode is supported, create a renderer and pass it to
+ * either SDL_SetRenderDrawBlendMode or SDL_SetTextureBlendMode. They will
+ * return with an error if the blend mode is not supported.
+ *
+ * This list describes the support of custom blend modes for each renderer in
+ * SDL 2.0.6. All renderers support the four blend modes listed in the
+ * SDL_BlendMode enumeration.
+ *
+ * - **direct3d**: Supports `SDL_BLENDOPERATION_ADD` with all factors.
+ * - **direct3d11**: Supports all operations with all factors. However, some
+ * factors produce unexpected results with `SDL_BLENDOPERATION_MINIMUM` and
+ * `SDL_BLENDOPERATION_MAXIMUM`.
+ * - **opengl**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
+ * factors. OpenGL versions 1.1, 1.2, and 1.3 do not work correctly with SDL
+ * 2.0.6.
+ * - **opengles**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
+ * factors. Color and alpha factors need to be the same. OpenGL ES 1
+ * implementation specific: May also support `SDL_BLENDOPERATION_SUBTRACT`
+ * and `SDL_BLENDOPERATION_REV_SUBTRACT`. May support color and alpha
+ * operations being different from each other. May support color and alpha
+ * factors being different from each other.
+ * - **opengles2**: Supports the `SDL_BLENDOPERATION_ADD`,
+ * `SDL_BLENDOPERATION_SUBTRACT`, `SDL_BLENDOPERATION_REV_SUBTRACT`
+ * operations with all factors.
+ * - **psp**: No custom blend mode support.
+ * - **software**: No custom blend mode support.
+ *
+ * Some renderers do not provide an alpha component for the default render
+ * target. The `SDL_BLENDFACTOR_DST_ALPHA` and
+ * `SDL_BLENDFACTOR_ONE_MINUS_DST_ALPHA` factors do not have an effect in this
+ * case.
+ *
+ * \param srcColorFactor the SDL_BlendFactor applied to the red, green, and

- * be available in the Windows Settings charm, as accessed from within the app.
- * SDL provides code to add a URL-based link there, which can point to the app's
- * privacy policy.
+ * On some platforms, currently Windows and X11, OpenGL drivers may support
+ * creating contexts with an OpenGL ES profile. By default SDL uses these

+ * library, e.g. that provided by the ANGLE project. This variable controls
+ * whether SDL follows this default behaviour or will always load an
+ * OpenGL ES library.
*
- * To setup a URL to an app's privacy policy, set SDL_HINT_WINRT_PRIVACY_POLICY_URL
- * before calling any SDL_Init() functions. The contents of the hint should
- * be a valid URL. For example, "http://www.example.com".
+ * Circumstances where this is useful include
+ * - Testing an app with a particular OpenGL ES implementation, e.g ANGLE,
+ * or emulator, e.g. those from ARM, Imagination or Qualcomm.
+ * - Resolving OpenGL ES function addresses at link time by linking with
+ * the OpenGL ES library instead of querying them at run time with
+ * SDL_GL_GetProcAddress().
*
- * The default value is "", which will prevent SDL from adding a privacy policy
- * link to the Settings charm. This hint should only be set during app init.
+ * Caution: for an application to work with the default behaviour across
+ * different OpenGL drivers it must query the OpenGL ES function
+ * addresses at run time using SDL_GL_GetProcAddress().
*
- * The label text of an app's "Privacy Policy" link may be customized via another
- * hint, SDL_HINT_WINRT_PRIVACY_POLICY_LABEL.
+ * This variable is ignored on most platforms because OpenGL ES is native
+ * or not supported.

+/**
+ * \brief Override for SDL_GetPreferredLocales()
*
- * Windows Phone devices typically feature a Back button. When pressed,
- * the OS will emit back-button-press events, which apps are expected to
- * handle in an appropriate manner. If apps do not explicitly mark these
- * events as 'Handled', then the OS will invoke its default behavior for
- * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
- * terminate the app (and attempt to switch to the previous app, or to the
- * device's home screen).
+ * If set, this will be favored over anything the OS might report for the
+ * user's preferred locales. Changing this hint at runtime will not generate
+ * a SDL_LOCALECHANGED event (but if you can change the hint, you can push
+ * your own event, if you want).
*
- * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
- * to mark back-button-press events as Handled, if and when one is sent to
- * the app.
+ * The format of this hint is a comma-separated list of language and locale,
+ * combined with an underscore, as is a common format: "en_GB". Locale is
+ * optional: "en". So you might have a list like this: "en_GB,jp,es_PT"

+/**
+ * \brief A variable describing the content orientation on QtWayland-based platforms.
*
- * Internally, Windows Phone sends back button events as parameters to
- * special back-button-press callback functions. Apps that need to respond
- * to back-button-press events are expected to register one or more
- * callback functions for such, shortly after being launched (during the
- * app's initialization phase). After the back button is pressed, the OS
- * will invoke these callbacks. If the app's callback(s) do not explicitly
- * mark the event as handled by the time they return, or if the app never
- * registers one of these callback, the OS will consider the event
- * un-handled, and it will apply its default back button behavior (terminate
- * the app).
+ * On QtWayland platforms, windows are rotated client-side to allow for custom
+ * transitions. In order to correctly position overlays (e.g. volume bar) and
+ * gestures (e.g. events view, close/minimize gestures), the system needs to
+ * know in which orientation the application is currently drawing its contents.
*
- * SDL registers its own back-button-press callback with the Windows Phone
- * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
- * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
- * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
- * If the hint's value is set to "1", the back button event's Handled
- * property will get set to 'true'. If the hint's value is set to something
- * else, or if it is unset, SDL will leave the event's Handled property
- * alone. (By default, the OS sets this property to 'false', to note.)
+ * This does not cause the window to be rotated or resized, the application
+ * needs to take care of drawing the content in the right orientation (the
+ * framebuffer is always in portrait mode).
*
- * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
- * back button is pressed, or can set it in direct-response to a back button
- * being pressed.
+ * This variable can be one of the following values:
+ * "primary" (default), "portrait", "landscape", "inverted-portrait", "inverted-landscape"

*
- * Setting this to "" or leaving it unset will have SDL use a reasonable
- * default: "audio stream" or something similar.
+ * Windows Phone devices typically feature a Back button. When pressed,
+ * the OS will emit back-button-press events, which apps are expected to
+ * handle in an appropriate manner. If apps do not explicitly mark these
+ * events as 'Handled', then the OS will invoke its default behavior for
+ * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ * terminate the app (and attempt to switch to the previous app, or to the
+ * device's home screen).
*
- * On targets where this is not supported, this hint does nothing.
+ * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ * to mark back-button-press events as Handled, if and when one is sent to
+ * the app.
+ *
+ * Internally, Windows Phone sends back button events as parameters to
+ * special back-button-press callback functions. Apps that need to respond
+ * to back-button-press events are expected to register one or more
+ * callback functions for such, shortly after being launched (during the
+ * app's initialization phase). After the back button is pressed, the OS
+ * will invoke these callbacks. If the app's callback(s) do not explicitly
+ * mark the event as handled by the time they return, or if the app never
+ * registers one of these callback, the OS will consider the event
+ * un-handled, and it will apply its default back button behavior (terminate
+ * the app).
+ *
+ * SDL registers its own back-button-press callback with the Windows Phone
+ * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ * If the hint's value is set to "1", the back button event's Handled
+ * property will get set to 'true'. If the hint's value is set to something
+ * else, or if it is unset, SDL will leave the event's Handled property
+ * alone. (By default, the OS sets this property to 'false', to note.)
+ *
+ * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ * back button is pressed, or can set it in direct-response to a back button
+ * being pressed.
+ *
+ * In order to get notified when a back button is pressed, SDL apps should
+ * register a callback function with SDL_AddEventWatch(), and have it listen
+ * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ * (Alternatively, SDL_KEYUP events can be listened-for. Listening for
+ * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ * set by such a callback, will be applied to the OS' current
+ * back-button-press event.
+ *
+ * More details on back button behavior in Windows Phone apps can be found

+ * function pointers to OpenGL extensions.
+ *
+ * There are some quirks to looking up OpenGL functions that require some
+ * extra care from the application. If you code carefully, you can handle
+ * these quirks without any platform-specific code, though:
+ *
+ * - On Windows, function pointers are specific to the current GL context;
+ * this means you need to have created a GL context and made it current
+ * before calling SDL_GL_GetProcAddress(). If you recreate your context or
+ * create a second context, you should assume that any existing function
+ * pointers aren't valid to use with it. This is (currently) a
+ * Windows-specific limitation, and in practice lots of drivers don't suffer
+ * this limitation, but it is still the way the wgl API is documented to
+ * work and you should expect crashes if you don't respect it. Store a copy
+ * of the function pointers that comes and goes with context lifespan.
+ * - On X11, function pointers returned by this function are valid for any
+ * context, and can even be looked up before a context is created at all.
+ * This means that, for at least some common OpenGL implementations, if you
+ * look up a function that doesn't exist, you'll get a non-NULL result that
+ * is _NOT_ safe to call. You must always make sure the function is actually
+ * available for a given GL context before calling it, by checking for the
+ * existence of the appropriate extension with SDL_GL_ExtensionSupported(),
+ * or verifying that the version of OpenGL you're using offers the function
+ * as core functionality.
+ * - Some OpenGL drivers, on all platforms, *will* return NULL if a function
+ * isn't supported, but you can't count on this behavior. Check for
+ * extensions you use, and if you get a NULL anyway, act as if that
+ * extension wasn't available. This is probably a bug in the driver, but you
+ * can code defensively for this scenario anyhow.
+ * - Just because you're on Linux/Unix, don't assume you'll be using X11.
+ * Next-gen display servers are waiting to replace it, and may or may not
+ * make the same promises about function pointers.
+ * - OpenGL function pointers must be declared `APIENTRY` as in the example
+ * code. This will ensure the proper calling convention is followed on
+ * platforms where this matters (Win32) thereby avoiding stack corruption.

+ * SDL_Init() simply forwards to calling SDL_InitSubSystem(). Therefore, the
+ * two may be used interchangeably. Though for readability of your code
+ * SDL_InitSubSystem() might be preferred.
+ *
+ * The file I/O (for example: SDL_RWFromFile) and threading (SDL_CreateThread)
+ * subsystems are initialized by default. Message boxes
+ * (SDL_ShowSimpleMessageBox) also attempt to work without initializing the
+ * video subsystem, in hopes of being useful in showing an error dialog when
+ * SDL_Init fails. You must specifically initialize other subsystems if you
+ * use them in your application.
+ *
+ * Logging (such as SDL_Log) works without initialization, too.
+ *
+ * `flags` may be any of the following OR'd together:
+ *
+ * - `SDL_INIT_TIMER`: timer subsystem
+ * - `SDL_INIT_AUDIO`: audio subsystem
+ * - `SDL_INIT_VIDEO`: video subsystem; automatically initializes the events
+ * subsystem
+ * - `SDL_INIT_JOYSTICK`: joystick subsystem; automatically initializes the
+ * events subsystem
+ * - `SDL_INIT_HAPTIC`: haptic (force feedback) subsystem
+ * - `SDL_INIT_GAMECONTROLLER`: controller subsystem; automatically
+ * initializes the joystick subsystem
+ * - `SDL_INIT_EVENTS`: events subsystem
+ * - `SDL_INIT_EVERYTHING`: all of the above subsystems
+ * - `SDL_INIT_NOPARACHUTE`: compatibility; this flag is ignored
+ *
+ * Subsystem initialization is ref-counted, you must call SDL_QuitSubSystem()
+ * for each SDL_InitSubSystem() to correctly shutdown a subsystem manually (or
+ * call SDL_Quit() to force shutdown). If a subsystem is already loaded then
+ * this call will increase the ref-count and return.

+ * - The return value is always success or failure, and not a device ID, which
+ * means you can only have one device open at a time with this function.
+ *
+ * \param desired an SDL_AudioSpec structure representing the desired output

+ * These flags specify how SDL should behave when a device cannot offer a

+ * doesn't offer, SDL will always try to get the closest equivalent.
+ *
+ * For example, if you ask for float32 audio format, but the sound card only

+ * factors. OpenGL versions 1.1, 1.2, and 1.3 do not work correctly with SDL
+ * 2.0.6.
+ * - **opengles**: Supports the `SDL_BLENDOPERATION_ADD` operation with all

+ * \brief Override for SDL_GetPreferredLocales()
*
- * Windows Phone devices typically feature a Back button. When pressed,
- * the OS will emit back-button-press events, which apps are expected to
- * handle in an appropriate manner. If apps do not explicitly mark these
- * events as 'Handled', then the OS will invoke its default behavior for
- * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
- * terminate the app (and attempt to switch to the previous app, or to the
- * device's home screen).
+ * If set, this will be favored over anything the OS might report for the
+ * user's preferred locales. Changing this hint at runtime will not generate
+ * a SDL_LOCALECHANGED event (but if you can change the hint, you can push
+ * your own event, if you want).
*
- * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
- * to mark back-button-press events as Handled, if and when one is sent to
- * the app.
+ * The format of this hint is a comma-separated list of language and locale,
+ * combined with an underscore, as is a common format: "en_GB". Locale is

+ * \brief A variable describing the content orientation on QtWayland-based platforms.
*
- * Internally, Windows Phone sends back button events as parameters to
- * special back-button-press callback functions. Apps that need to respond
- * to back-button-press events are expected to register one or more
- * callback functions for such, shortly after being launched (during the
- * app's initialization phase). After the back button is pressed, the OS
- * will invoke these callbacks. If the app's callback(s) do not explicitly
- * mark the event as handled by the time they return, or if the app never
- * registers one of these callback, the OS will consider the event
- * un-handled, and it will apply its default back button behavior (terminate
- * the app).
+ * On QtWayland platforms, windows are rotated client-side to allow for custom
+ * transitions. In order to correctly position overlays (e.g. volume bar) and
+ * gestures (e.g. events view, close/minimize gestures), the system needs to
+ * know in which orientation the application is currently drawing its contents.
*
- * SDL registers its own back-button-press callback with the Windows Phone
- * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
- * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
- * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
- * If the hint's value is set to "1", the back button event's Handled
- * property will get set to 'true'. If the hint's value is set to something
- * else, or if it is unset, SDL will leave the event's Handled property
- * alone. (By default, the OS sets this property to 'false', to note.)
+ * This does not cause the window to be rotated or resized, the application
+ * needs to take care of drawing the content in the right orientation (the
+ * framebuffer is always in portrait mode).
*
- * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
- * back button is pressed, or can set it in direct-response to a back button
- * being pressed.
+ * This variable can be one of the following values:
+ * "primary" (default), "portrait", "landscape", "inverted-portrait", "inverted-landscape"

*
- * Setting this to "" or leaving it unset will have SDL use a reasonable
- * default: "audio stream" or something similar.
+ * Windows Phone devices typically feature a Back button. When pressed,
+ * the OS will emit back-button-press events, which apps are expected to
+ * handle in an appropriate manner. If apps do not explicitly mark these
+ * events as 'Handled', then the OS will invoke its default behavior for
+ * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ * terminate the app (and attempt to switch to the previous app, or to the
+ * device's home screen).
*
- * On targets where this is not supported, this hint does nothing.
+ * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ * to mark back-button-press events as Handled, if and when one is sent to
+ * the app.
+ *
+ * Internally, Windows Phone sends back button events as parameters to
+ * special back-button-press callback functions. Apps that need to respond
+ * to back-button-press events are expected to register one or more
+ * callback functions for such, shortly after being launched (during the
+ * app's initialization phase). After the back button is pressed, the OS
+ * will invoke these callbacks. If the app's callback(s) do not explicitly
+ * mark the event as handled by the time they return, or if the app never
+ * registers one of these callback, the OS will consider the event
+ * un-handled, and it will apply its default back button behavior (terminate
+ * the app).
+ *
+ * SDL registers its own back-button-press callback with the Windows Phone
+ * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ * If the hint's value is set to "1", the back button event's Handled
+ * property will get set to 'true'. If the hint's value is set to something
+ * else, or if it is unset, SDL will leave the event's Handled property
+ * alone. (By default, the OS sets this property to 'false', to note.)
+ *
+ * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ * back button is pressed, or can set it in direct-response to a back button
+ * being pressed.
+ *
+ * In order to get notified when a back button is pressed, SDL apps should
+ * register a callback function with SDL_AddEventWatch(), and have it listen
+ * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ * (Alternatively, SDL_KEYUP events can be listened-for. Listening for
+ * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ * set by such a callback, will be applied to the OS' current
+ * back-button-press event.
+ *
+ * More details on back button behavior in Windows Phone apps can be found

+ *
+ * There are some quirks to looking up OpenGL functions that require some
+ * extra care from the application. If you code carefully, you can handle
+ * these quirks without any platform-specific code, though:
+ *
+ * - On Windows, function pointers are specific to the current GL context;
+ * this means you need to have created a GL context and made it current
+ * before calling SDL_GL_GetProcAddress(). If you recreate your context or
+ * create a second context, you should assume that any existing function
+ * pointers aren't valid to use with it. This is (currently) a
+ * Windows-specific limitation, and in practice lots of drivers don't suffer
+ * this limitation, but it is still the way the wgl API is documented to
+ * work and you should expect crashes if you don't respect it. Store a copy
+ * of the function pointers that comes and goes with context lifespan.
+ * - On X11, function pointers returned by this function are valid for any
+ * context, and can even be looked up before a context is created at all.
+ * This means that, for at least some common OpenGL implementations, if you
+ * look up a function that doesn't exist, you'll get a non-NULL result that
+ * is _NOT_ safe to call. You must always make sure the function is actually
+ * available for a given GL context before calling it, by checking for the
+ * existence of the appropriate extension with SDL_GL_ExtensionSupported(),
+ * or verifying that the version of OpenGL you're using offers the function
+ * as core functionality.
+ * - Some OpenGL drivers, on all platforms, *will* return NULL if a function
+ * isn't supported, but you can't count on this behavior. Check for
+ * extensions you use, and if you get a NULL anyway, act as if that
+ * extension wasn't available. This is probably a bug in the driver, but you
+ * can code defensively for this scenario anyhow.
+ * - Just because you're on Linux/Unix, don't assume you'll be using X11.
+ * Next-gen display servers are waiting to replace it, and may or may not
+ * make the same promises about function pointers.
+ * - OpenGL function pointers must be declared `APIENTRY` as in the example
+ * code. This will ensure the proper calling convention is followed on
