+The Academic Free License
+v.2.1
+
+This Academic Free License (the "License") applies to any original work of authorship (the "Original Work") whose owner (the "Licensor") has placed the following notice immediately following the copyright notice for the Original Work:
+
+     Licensed under the Academic Free License version 2.1
+
+1) Grant of Copyright License. Licensor hereby grants You a world-wide, royalty-free, non-exclusive, perpetual, sublicenseable license to do the following:
+
+     a) to reproduce the Original Work in copies;
+     b) to prepare derivative works ("Derivative Works") based upon the Original Work;
+     c) to distribute copies of the Original Work and Derivative Works to the public;
+     d) to perform the Original Work publicly; and
+     e) to display the Original Work publicly.
+
+2) Grant of Patent License. Licensor hereby grants You a world-wide, royalty-free, non-exclusive, perpetual, sublicenseable license, under patent claims owned or controlled by the Licensor that are embodied in the Original Work as furnished by the Licensor, to make, use, sell and offer for sale the Original Work and Derivative Works.
+
+3) Grant of Source Code License. The term "Source Code" means the preferred form of the Original Work for making modifications to it and all available documentation describing how to modify the Original Work. Licensor hereby agrees to provide a machine-readable copy of the Source Code of the Original Work along with each copy of the Original Work that Licensor distributes. Licensor reserves the right to satisfy this obligation by placing a machine-readable copy of the Source Code in an information repository reasonably calculated to permit inexpensive and convenient access by You for as long as Licensor continues to distribute the Original Work, and by publishing the address of that information repository in a notice immediately following the copyright notice that applies to the Original Work.
+
+4) Exclusions From License Grant. Neither the names of Licensor, nor the names of any contributors to the Original Work, nor any of their trademarks or service marks, may be used to endorse or promote products derived from this Original Work without express prior written permission of the Licensor. Nothing in this License shall be deemed to grant any rights to trademarks, copyrights, patents, trade secrets or any other intellectual property of Licensor except as expressly stated herein. No patent license is granted to make, use, sell or offer to sell embodiments of any patent claims other than the licensed claims defined in Section 2. No right is granted to the trademarks of Licensor even if such marks are included in the Original Work. Nothing in this License shall be interpreted to prohibit Licensor from licensing under different terms from this License any Original Work that Licensor otherwise would have a right to license.
+
+5) This section intentionally omitted.
+
+6) Attribution Rights. You must retain, in the Source Code of any Derivative Works that You create, all copyright, patent or trademark notices from the Source Code of the Original Work, as well as any notices of licensing and any descriptive text identified therein as an "Attribution Notice." You must cause the Source Code for any Derivative Works that You create to carry a prominent Attribution Notice reasonably calculated to inform recipients that You have modified the Original Work.
+
+7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that the copyright in and to the Original Work and the patent rights granted herein by Licensor are owned by the Licensor or are sublicensed to You under the terms of this License with the permission of the contributor(s) of those copyrights and patent rights. Except as expressly stated in the immediately proceeding sentence, the Original Work is provided under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without limitation, the warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this License. No license to Original Work is granted hereunder except under this disclaimer.
+
+8) Limitation of Liability. Under no circumstances and under no legal theory, whether in tort (including negligence), contract, or otherwise, shall the Licensor be liable to any person for any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or the use of the Original Work including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses. This limitation of liability shall not apply to liability for death or personal injury resulting from Licensor'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.
+
+ 9) Acceptance and Termination. If You distribute copies of the Original Work or a Derivative Work, You must make a reasonable effort under the circumstances to obtain the express assent of recipients to the terms of this License. Nothing else but this License (or another written agreement between Licensor and You) grants You permission to create Derivative Works based upon the Original Work or to exercise any of the rights granted in Section 1 herein, and any attempt to do so except under the terms of this License (or another written agreement between Licensor and You) is expressly prohibited by U.S. copyright law, the equivalent laws of other countries, and by international treaty. Therefore, by exercising any of the rights granted to You in Section 1 herein, You indicate Your acceptance of this License and all of its terms and conditions.
+
+10) Termination for Patent Action. This License shall terminate automatically and You may no longer exercise any of the rights granted to You by this License as of the date You commence an action, including a cross-claim or counterclaim, against Licensor or any licensee alleging that the Original Work infringes a patent. This termination provision shall not apply for an action alleging patent infringement by combinations of the Original Work with other software or hardware.
+
+11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this License may be brought only in the courts of a jurisdiction wherein the Licensor resides or in which Licensor conducts its primary business, and under the laws of that jurisdiction excluding its conflict-of-law provisions. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any use of the Original Work outside the scope of this License or after its termination shall be subject to the requirements and penalties of the U.S. Copyright Act, 17 U.S.C. § 101 et seq., the equivalent laws of other countries, and international treaty. This section shall survive the termination of this License.
+
+12) Attorneys Fees. In any action to enforce the terms of this License or seeking damages relating thereto, the prevailing party shall be entitled to recover its costs and expenses, including, without limitation, reasonable attorneys' fees and costs incurred in connection with such action, including any appeal of such action. This section shall survive the termination of this License.
+
+13) 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.
+
+14) Definition of "You" in This License. "You" throughout this License, whether in upper or lower case, means an individual or a legal entity exercising rights under, and complying with all of the terms of, this License. For legal entities, "You" includes any entity that controls, is controlled by, or is under common control with you. For purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
+
+15) Right to Use. You may use the Original Work in all ways not otherwise restricted or conditioned by this License or by law, and Licensor promises not to interfere with or be responsible for such uses by You.

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+    \example serialization/cbordump
+    \title Cbordump Example
+
+    \brief The Cbordump example demonstrates how to parse files in CBOR-format.
+
+    The Cbordump example reads from files or stdin content in CBOR-format and
+    dumps the decoded content to stdout. The cbordump utility can output in
+    CBOR diagnostic notation (which is similar to JSON), or it can have a
+    verbose output where each byte input is displayed with the encoding beside
+    it. This example shows how to use the QCborStreamReader class directly to
+    parse CBOR content.
+
+    \sa QCborStreamReader
+
+    \image cbordump.png
+
+    \section1 The Cbordumper Class
+
+    The Cbordumper class contains a QCborStreamReader object that is
+    initialized using the QFile object argument passed to the CborDumper
+    constructor. Based on the arguments the dump function calls either
+    dumpOne() or dumpOneDetailed() to dump the contents to stdout,
+
+    \snippet serialization/cbordump/main.cpp 0
+
+    \section2 The dumpOne() Function
+
+    The type() function of the QCborStreamReader is used in a switch statement
+    to print out for each type. If the type is an array or map, the content is
+    iterated upon, and for each entry the dumpOne() function is called
+    recursively with a higher indentation argument. If the type is a tag, it
+    is printed out and dumpOne() is called once without increasing the
+    indentation argument.
+
+    \section2 The dumpOneDetailed() Function
+
+    This function dumps out both the incoming bytes and the decoded contents
+    on the same line. It uses lambda functions to print out the bytes and
+    decoded content, but otherwise has a similar structure as dumpOne().
+
+    \section1 CborDescription
+
+    The tagDescriptions table, describing the CBOR-tags available, is
+    automatically generated from an XML-file available from the iana.org
+    website.

+    The Convert example converts between the serialization formats JSON, CBOR,
+    XML, QDataStream and text. It can also auto detect the format being used.
+    Not all formats support both input and output, and they have different
+    sets of which types they support. QDataStream and XML are the richest,
+    followed by CBOR, then JSON, and then the plain text one.
+
+    \image convert.png
+
+    \section1 The Converter Class
+
+    The Converter class is the abstract superclass for all the converters to
+    and from all the formats. They all convert to and from the QVariant class,
+    which is used to represent all the datastructures internally.
+    The name() function returns the name of the converter. The directions()
+    function is used to determine if a converter can be used for input, output,
+    or both. The outputOptions() and optionsHelp() functions are used to get
+    and query which options are used by the different converters. The
+    probeFile() function is used to determine if a file has the same file
+    format as the converter. The loadFile() function deserializes the given
+    file, while the saveFile() serializes to the given file.
+
+    \section1 The CborConverter Class
+
+    The CborConverter class shows how to serialize to and from the CBOR-format.
+    There is also a CborDiagnosticDumper class to output in CBOR diagnostic
+    notation. That is similar to JSON, but not exactly, because it allows
+    displaying the contents of a CBOR stream losslessly, while a conversion
+    to JSON is lossy.
+
+    The convertCborValue() function is used to convert a QCborValue to a
+    QVariant. It uses the helper functions convertCborMap() and
+    convertCborArray().
+    \snippet serialization/convert/cborconverter.cpp 0
+
+    A CBOR-file is read using loadFile() function.
+    \snippet serialization/convert/cborconverter.cpp 2
+
+    The convertFromVariant() function is used to convert a QVariant to a
+    QCborValue.
+    \snippet serialization/convert/cborconverter.cpp 1
+
+    A CBOR-file is written using the saveFile() function.
+    \snippet serialization/convert/cborconverter.cpp 3

+
+    \sa {CBOR Support in Qt}
+
+    \section1 The DataStreamConverter Class
+
+    The DataStreamConverter class is used to serialize to and from the
+    QDataStream format. There is also the DataStreamDumper class for outputting
+    the data lossless in a non-standardized human readable format.
+
+    \section1 The JsonConverter Class
+
+    The JsonConverter class is used to serialize to and from the JSON-format.
+    \sa {JSON Support in Qt}
+
+    \section1 The XmlConverter Class
+
+    The XmlConverter class is used to serialize to and from the XML-format.
+
+    \section1 The TextConverter Class
+
+    The TextConverter class is used to serialize to and from a text format.
+
+    \section1 The NullConverter Class
+
+    The NullConverter class is an output serializer that does nothing.

-CHANGES BETWEEN 2.12.0 and 2.12.1
+CHANGES BETWEEN 2.12.1 and 2.13.0 (2023-Feb-09)
+
+  I. IMPORTANT CHANGES
+
+  - The demo program `ftinspect` has  been completely updated and much
+    enhanced.  It now  combines the functionality of  almost all other
+    graphical FreeType  demo programs into a  single application based
+    on the Qt framework.  This was Charlie Jiang's GSoC 2022 project.
+
+  - The 'COLR' v1 API is now considered as stable.
+
+      https://learn.microsoft.com/en-us/typography/opentype/spec/colr
+
+
+  III. MISCELLANEOUS
+
+  - For  OpenType  Variable Fonts,  `avar`  table  format 2.0  is  now
+    supported.  The code was contributed by Behdad Esfahbod.
+
+    Note that this is an extension supported on recent Apple platforms
+    and by HarfBuzz, but not yet in the OpenType standard!  See
+
+      https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
+
+    for the specification.  To deactivate it, define the configuration
+    macro 'TT_CONFIG_OPTION_NO_BORING_EXPANSION'.
+
+  - A new API  `FT_GlyphSlot_Slant` to slant a glyph by  a given angle
+    has been added.   Note that this function is  part of `ftsynth.h`,
+    which is still considered to be in alpha stage.
+
+  - TrueType interpreter version 38  (also known as 'Infinality') that
+    was first introduced about 10 years  ago in FreeType 2.4.11 is now
+    deprecated and slated to be removed in the next version.  TrueType
+    interpreter version 40 has been FreeType's default version for six
+    years now and provides an excellent alternative.  This is the last
+    FreeType     version     with    TT_INTERPRETER_VERSION_38     and
+    TT_INTERPRETER_VERSION_40 treated differently.
+
+  - The  only  referenced  but never  documented  configuration  macro
+    `FT_CONFIG_OPTION_NO_GLYPH_NAMES` has been removed.
+
+  - The `ftbench` demo  program got a new command line  option `-e` to
+    set a charmap index.
+
+  - Specifying  a point  size is  now optional  for the  demo programs
+    `ftgrid`, `ftmulti`,  `ftstring`, and  `ftview`.  If not  given, a
+    default size is used.
+
+  - For  `ftgrid`,  `ftstring`, and  `ftview`,  option  `-e` now  also
+    accepts a numeric value to set a charmap index.
+
+  - In  `ftstring`, it  is  now  possible to  set  the displayed  text
+    interactively by pressing the 'Enter' key.
+
+  - `ftmulti` can now handle up to 16 design axes.
+
+  - To  avoid  reserved identifiers  that  are  globally defined,  the
+    auto-hinter  debugging   macros  (which  are  only   available  if
+    `FT_DEBUG_AUTOFIT` is defined)
+
+    ```
+    _af_debug_disable_horz_hints
+    _af_debug_disable_vert_hints
+    _af_debug_disable_blue_hints
+    _af_debug_hints
+    ```
+
+    have been renamed to
+
+    ```
+    af_debug_disable_horz_hints_
+    af_debug_disable_vert_hints_
+    af_debug_disable_blue_hints_
+    af_debug_hints_

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

+
+Overview of changes leading to 6.0.0
+Friday, December 16, 2022
+====================================
+- A new API have been added to pre-process the face and speed up future
+  subsetting operations on that face. Provides up to a 95% reduction in
+  subsetting times when the same face is subset more than once.
+
+  For more details and benchmarks, see:
+  https://github.com/harfbuzz/harfbuzz/blob/main/docs/subset-preprocessing.md
+
+  (Garret Rieger, Behdad Esfahbod)
+
+- Shaping have been speedup by skipping entire lookups when the buffer contents
+  don't intersect with the lookup. Shows up to a 10% speedup in shaping some
+  fonts. (Behdad Esfahbod)
+
+- A new experimental feature, “Variable Composites” (enabled by passing
+  -Dexperimental_api=true to meson), is also featured in this release.
+  This technology enables drastic compression of fonts in the Chinese,
+  Japanese, Korean, and other writing systems, by reusing the OpenType Font
+  Variations technology for encoding “smart components” into the font.
+
+  The specification for these  extensions to the font format can be found in:
+  https://github.com/harfbuzz/boring-expansion-spec/blob/glyf1/glyf1.md
+
+  A test variable-font with ~7160 Hangul syllables derived from the
+  NotoSerifKR-VF font has been built, with existing OpenType technology, as
+  well as with the new Variable Composites (VarComposites) technology. The
+  VarComposites font is over 90% smaller than the OpenType version of the font!
+  Both fonts can be obtained from the “smarties” repository:
+  https://github.com/behdad/smarties/tree/3.0/fonts/hangul/serif
+
+  When building HarfBuzz with experimental features enabled, you can test
+  the “smarties” font with a sample character like this:
+
+  $ hb-view butchered-hangul-serif-smarties-variable.ttf -u AE01 --variations=wght=700
+
+  (Behdad Esfahbod)
+
+- The HarfBuzz subsetter can now drop axes by pinning them to specific values
+  (also referred to as instancing). There are a couple of restrictions
+  currently:
+
+  - Only works with TrueType (“glyf”) based fonts. “CFF2” fonts are not yet
+    supported.
+  - Only supports the case where all axes in a font are pinned.
+
+  (Garret Rieger, Qunxin Liu)
+
+- Miscellaneous fixes and improvements.
+
+  (Behdad Esfahbod, Christoph Reiter, David Corbett, Eli Schwartz, Garret
+   Rieger, Joel Auterson, Jordan Petridis, Khaled Hosny, Lorenz Wildberg,
+   Marco Rebhan, Martin Storsjö, Matthias Clasen, Qunxin Liu, Satadru Pramanik)
+
+
+- New API
++hb_subset_input_pin_axis_location()
++hb_subset_input_pin_axis_to_default()
++hb_subset_preprocess()
+
+

+- Subsetter repacker fixes. (Garret Rieger)
+- Adjust Grapheme clusters for Katakana voiced sound marks. (Behdad Esfahbod)

+HarfBuzz is a text shaping engine. It primarily supports [OpenType][1], but also
+[Apple Advanced Typography][2]. HarfBuzz is used in Android, Chrome,
+ChromeOS, Firefox, GNOME, GTK+, KDE, LibreOffice, OpenJDK, PlayStation, Qt,
+XeTeX, and other places.

+## Documentation
+
+For user manual as well as API documentation, check: https://harfbuzz.github.io
+
+## Download
+
+For tarball releases of HarfBuzz, look [here][3]. At the same place you
+will also find Win32/Win64 binary bundles that include libharfbuzz DLL,
+hb-view.exe, hb-shape.exe, and all dependencies.
+
+The canonical source tree is available on [github][4].
+
+The API that comes with `hb.h` will not change incompatibly. Other, peripheral,
+headers are more likely to go through minor modifications, but again, we do our
+best to never change API in an incompatible way. We will never break the ABI.
+
+If you are not sure whether Pango or HarfBuzz is right for you, read [Pango vs

 For build information, see [BUILD.md](BUILD.md).
 
 For custom configurations, see [CONFIG.md](CONFIG.md).
 
-For test execution, see [TESTING.md](TESTING.md).
+For testing and profiling, see [TESTING.md](TESTING.md).
 
-Documentation: https://harfbuzz.github.io
+To get a better idea of where HarfBuzz stands in the text rendering stack you

+*   October 2012, [HarfBuzz, The Free and Open Text Shaping Engine][8],
+*   October 2009, [HarfBuzz: the Free and Open Shaping Engine][9].
+
+Both development and user support discussion around HarfBuzz happens on the
+[github][4].

+## Name
+
+HarfBuzz (حرف‌باز) is my Persian translation of “[OpenType][1]”,
+transliterated using the Latin script. It sports a second meaning, but that
+ain’t translatable.
+
+> Background: Originally there was this font format called TrueType. People and
+> companies started calling their type engines all things ending in Type:
+> FreeType, CoolType, ClearType, etc. And then came OpenType, which is the
+> successor of TrueType. So, for my OpenType implementation, I decided to stick
+> with the concept but use the Persian translation. Which is fitting given that
+> Persian is written in the Arabic script, and OpenType is an extension of
+> TrueType that adds support for complex script rendering, and HarfBuzz is an
+> implementation of OpenType complex text shaping.

+ * using cairo_text_cluster_allocate() and placed in @clusters.  In this case,

+ * would be the fractional-precision part of the font scale.
+ * This is necessary because #hb_position_t values are integer
+ * types and you need to leave room for fractional values
+ * in there.
+ *
+ * For example, to set the font size to 20, with 64
+ * levels of fractional precision you would call
+ * `hb_font_set_scale(font, 20 * 64, 20 * 64)`.
+ *
+ * In the example above, even what font size 20 means is up to
+ * you. It might be 20 pixels, or 20 points, or 20 millimeters.
+ * HarfBuzz does not care about that.  You can set the point
+ * size of the font using hb_font_set_ptem(), and the pixel
+ * size using hb_font_set_ppem().
+ *
+ * The choice of scale is yours but needs to be consistent between
+ * what you set here, and what you expect out of #hb_position_t
+ * as well has draw / paint API output values.
+ *
+ * Fonts default to a scale equal to the UPEM value of their face.
+ * A font with this setting is sometimes called an "unscaled" font.

+2.1.5
+=====
+
+### Significant changes relative to 2.1.4:
+
+1. Fixed issues in the build system whereby, when using the Ninja Multi-Config
+CMake generator, a static build of libjpeg-turbo (a build in which
+`ENABLE_SHARED` is `0`) could not be installed, a Windows installer could not
+be built, and the Java regression tests failed.
+
+2. Fixed a regression introduced by 2.0 beta1[15] that caused a buffer overrun
+in the progressive Huffman encoder when attempting to transform a
+specially-crafted malformed 12-bit-per-component JPEG image into a progressive
+12-bit-per-component JPEG image using a 12-bit-per-component build of
+libjpeg-turbo (`-DWITH_12BIT=1`.)  Given that the buffer overrun was fully
+contained within the progressive Huffman encoder structure and did not cause a
+segfault or other user-visible errant behavior, given that the lossless
+transformer (unlike the decompressor) is not generally exposed to arbitrary
+data exploits, and given that 12-bit-per-component builds of libjpeg-turbo are
+uncommon, this issue did not likely pose a security risk.
+
+3. Fixed an issue whereby, when using a 12-bit-per-component build of
+libjpeg-turbo (`-DWITH_12BIT=1`), passing samples with values greater than 4095
+or less than 0 to `jpeg_write_scanlines()` caused a buffer overrun or underrun
+in the RGB-to-YCbCr color converter.
+
+4. Fixed a floating point exception that occurred when attempting to use the
+jpegtran `-drop` and `-trim` options to losslessly transform a
+specially-crafted malformed JPEG image.
+
+5. Fixed an issue in `tjBufSizeYUV2()` whereby it returned a bogus result,
+rather than throwing an error, if the `align` parameter was not a power of 2.
+Fixed a similar issue in `tjCompressFromYUV()` whereby it generated a corrupt
+JPEG image in certain cases, rather than throwing an error, if the `align`
+parameter was not a power of 2.
+
+6. Fixed an issue whereby `tjDecompressToYUV2()`, which is a wrapper for
+`tjDecompressToYUVPlanes()`, used the desired YUV image dimensions rather than
+the actual scaled image dimensions when computing the plane pointers and
+strides to pass to `tjDecompressToYUVPlanes()`.  This caused a buffer overrun
+and subsequent segfault if the desired image dimensions exceeded the scaled
+image dimensions.
+
+7. Fixed an issue whereby, when decompressing a 12-bit-per-component JPEG image
+(`-DWITH_12BIT=1`) using an alpha-enabled output color space such as
+`JCS_EXT_RGBA`, the alpha channel was set to 255 rather than 4095.
+
+8. Fixed an issue whereby the Java version of TJBench did not accept a range of
+quality values.
+
+9. Fixed an issue whereby, when `-progressive` was passed to TJBench, the JPEG
+input image was not transformed into a progressive JPEG image prior to
+decompression.
+
+
+2.1.4
+=====
+
+### Significant changes relative to 2.1.3:
+
+1. Fixed a regression introduced in 2.1.3 that caused build failures with
+Visual Studio 2010.
+
+2. The `tjDecompressHeader3()` function in the TurboJPEG C API and the
+`TJDecompressor.setSourceImage()` method in the TurboJPEG Java API now accept
+"abbreviated table specification" (AKA "tables-only") datastreams, which can be
+used to prime the decompressor with quantization and Huffman tables that can be
+used when decompressing subsequent "abbreviated image" datastreams.
+
+3. libjpeg-turbo now performs run-time detection of AltiVec instructions on
+OS X/PowerPC systems if AltiVec instructions are not enabled at compile time.
+This allows both AltiVec-equipped (PowerPC G4 and G5) and non-AltiVec-equipped
+(PowerPC G3) CPUs to be supported using the same build of libjpeg-turbo.
+
+4. Fixed an error ("Bogus virtual array access") that occurred when attempting
+to decompress a progressive JPEG image with a height less than or equal to one
+iMCU (8 * the vertical sampling factor) using buffered-image mode with
+interblock smoothing enabled.  This was a regression introduced by
+2.1 beta1[6(b)].
+
+5. Fixed two issues that prevented partial image decompression from working
+properly with buffered-image mode:
+
+     - Attempting to call `jpeg_crop_scanline()` after
+`jpeg_start_decompress()` but before `jpeg_start_output()` resulted in an error
+("Improper call to JPEG library in state 207".)
+     - Attempting to use `jpeg_skip_scanlines()` resulted in an error ("Bogus
+virtual array access") under certain circumstances.

+Most of the makefiles used to allow you to run "make install" to put

+the conventional build and install procedures driven by the configure

-You will want to look into zconf.h to tell zlib (and thus libpng) that
-it cannot allocate more than 64K at a time.  Even if you can, the memory
-won't be accessible.  So limit zlib and libpng to 64K by defining MAXSEG_64K.
+VIII. Configuring for DOS and other 16-bit platforms
 
-IX. Configuring for DOS
+Officially, the support for 16-bit platforms has been removed.
 
 For DOS users who only have access to the lower 640K, you will
 have to limit zlib's memory usage via a png_set_compression_mem_level()
 call.  See zlib.h or zconf.h in the zlib library for more information.
 
-X. Configuring for Medium Model
+You may be or may not be in luck if you target the "large" memory model,
+but all the smaller models ("small", "compact" and "medium") are known
+to be unworkable.  For DOS users who have access beyond the lower 640K,
+a "flat" 32-bit DOS model (such as DJGPP) is strongly recommended.
 
-Libpng's support for medium model has been tested on most of the popular
-compilers.  Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
-defined, and FAR gets defined to far in pngconf.h, and you should be
-all set.  Everything in the library (except for zlib's structure) is
-expecting far data.  You must use the typedefs with the p or pp on
-the end for pointers (or at least look at them and be careful).  Make
-note that the rows of data are defined as png_bytepp, which is
-an "unsigned char far * far *".
+For DOS users who only have access to the lower 640K, you will have to
+limit zlib's memory usage via a png_set_compression_mem_level() call.
+You will also have to look into zconf.h to tell zlib (and thus libpng)

+At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50
+frames) was allocated on the system stack. If this was not big enough, the heap
+was used for a larger vector. However, it turns out that there are environments

+After another refactoring, the heap is used exclusively, but a pointer the

     Advantages:
       - The execution can be continued from any LIR instruction. In other
         words, it is possible to jump to any label from anywhere, even from
-        a code fragment, which is compiled later, if both compiled code
-        shares the same context. See sljit_emit_enter for more details
-      - Supports self modifying code: target of (conditional) jump and call

+        context is the same. See sljit_emit_enter for more details.
+      - Supports self modifying code: target of any jump and call
         instructions and some constant values can be dynamically modified
-        during runtime

         - although it is not suggested to do it frequently
         - can be used for inline caching: save an important value once
           in the instruction stream
-        - since this feature limits the optimization possibilities, a
-          special flag must be passed at compile time when these
-          instructions are emitted
       - A fixed stack space can be allocated for local variables
       - The compiler is thread-safe
       - The compiler is highly configurable through preprocessor macros.
         You can disable unneeded features (multithreading in single
         threaded applications), and you can use your own system functions

     Disadvantages:
-      - No automatic register allocation, and temporary results are
-        not stored on the stack. (hence the name comes)
+      - The compiler is more like a platform independent assembler, so
+        there is no built-in variable management. Registers and stack must
+        be managed manually (the name of the compiler refers to this).
     In practice:

         - One of the saved registers typically points to a stack interface

+** File Locking Notes:  (Mostly about windows but also some info for Unix)
+**
+** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
+** those functions are not available.  So we use only LockFile() and
+** UnlockFile().
+**
+** LockFile() prevents not just writing but also reading by other processes.
+** A SHARED_LOCK is obtained by locking a single randomly-chosen
+** byte out of a specific range of bytes. The lock byte is obtained at
+** random so two separate readers can probably access the file at the
+** same time, unless they are unlucky and choose the same lock byte.
+** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
+** There can only be one writer.  A RESERVED_LOCK is obtained by locking
+** a single byte of the file that is designated as the reserved lock byte.
+** A PENDING_LOCK is obtained by locking a designated byte different from
+** the RESERVED_LOCK byte.
+**
+** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
+** which means we can use reader/writer locks.  When reader/writer locks
+** are used, the lock is placed on the same range of bytes that is used
+** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
+** will support two or more Win95 readers or two or more WinNT readers.
+** But a single Win95 reader will lock out all WinNT readers and a single
+** WinNT reader will lock out all other Win95 readers.
+**
+** The following #defines specify the range of bytes used for locking.
+** SHARED_SIZE is the number of bytes available in the pool from which
+** a random byte is selected for a shared lock.  The pool of bytes for
+** shared locks begins at SHARED_FIRST.
+**
+** The same locking strategy and
+** byte ranges are used for Unix.  This leaves open the possibility of having
+** clients on win95, winNT, and unix all talking to the same shared file
+** and all locking correctly.  To do so would require that samba (or whatever
+** tool is being used for file sharing) implements locks correctly between
+** windows and unix.  I'm guessing that isn't likely to happen, but by
+** using the same locking range we are at least open to the possibility.
+**
+** Locking in windows is manditory.  For this reason, we cannot store
+** actual data in the bytes used for locking.  The pager never allocates
+** the pages involved in locking therefore.  SHARED_SIZE is selected so
+** that all locks will fit on a single page even at the minimum page size.
+** PENDING_BYTE defines the beginning of the locks.  By default PENDING_BYTE
+** is set high so that we don't have to allocate an unused page except
+** for very large databases.  But one should test the page skipping logic
+** by setting PENDING_BYTE low and running the entire regression suite.
+**
+** Changing the value of PENDING_BYTE results in a subtly incompatible
+** file format.  Depending on how it is changed, you might not notice
+** the incompatibility right away, even running a full regression test.
+** The default location of PENDING_BYTE is the first byte past the
+** 1GB boundary.

-** File Locking Notes:  (Mostly about windows but also some info for Unix)
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available.  So we use only LockFile() and
-** UnlockFile().
-**
-** LockFile() prevents not just writing but also reading by other processes.
-** A SHARED_LOCK is obtained by locking a single randomly-chosen
-** byte out of a specific range of bytes. The lock byte is obtained at
-** random so two separate readers can probably access the file at the
-** same time, unless they are unlucky and choose the same lock byte.
-** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
-** There can only be one writer.  A RESERVED_LOCK is obtained by locking
-** a single byte of the file that is designated as the reserved lock byte.
-** A PENDING_LOCK is obtained by locking a designated byte different from
-** the RESERVED_LOCK byte.
-**
-** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
-** which means we can use reader/writer locks.  When reader/writer locks
-** are used, the lock is placed on the same range of bytes that is used
-** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
-** will support two or more Win95 readers or two or more WinNT readers.
-** But a single Win95 reader will lock out all WinNT readers and a single
-** WinNT reader will lock out all other Win95 readers.
-**
-** The following #defines specify the range of bytes used for locking.
-** SHARED_SIZE is the number of bytes available in the pool from which
-** a random byte is selected for a shared lock.  The pool of bytes for
-** shared locks begins at SHARED_FIRST.

-** The same locking strategy and
-** byte ranges are used for Unix.  This leaves open the possibility of having
-** clients on win95, winNT, and unix all talking to the same shared file
-** and all locking correctly.  To do so would require that samba (or whatever
-** tool is being used for file sharing) implements locks correctly between
-** windows and unix.  I'm guessing that isn't likely to happen, but by
-** using the same locking range we are at least open to the possibility.
-**
-** Locking in windows is manditory.  For this reason, we cannot store
-** actual data in the bytes used for locking.  The pager never allocates
-** the pages involved in locking therefore.  SHARED_SIZE is selected so
-** that all locks will fit on a single page even at the minimum page size.
-** PENDING_BYTE defines the beginning of the locks.  By default PENDING_BYTE
-** is set high so that we don't have to allocate an unused page except
-** for very large databases.  But one should test the page skipping logic
-** by setting PENDING_BYTE low and running the entire regression suite.
-**
-** Changing the value of PENDING_BYTE results in a subtly incompatible
-** file format.  Depending on how it is changed, you might not notice
-** the incompatibility right away, even running a full regression test.
-** The default location of PENDING_BYTE is the first byte past the
-** 1GB boundary.

+ * For the default windowBits of 15 and memLevel of 8, this function returns a

+ * is an expansion of ~0.03%, plus a small constant.

  *
- * For any setting other than those defaults for windowBits and memLevel,
- * the value returned is a conservative worst case for the maximum expansion
- * resulting from using fixed blocks instead of stored blocks, which deflate
- * can emit on compressed data for some combinations of the parameters.
+ * Both the 0.03% and 4% derive from the overhead of stored blocks. The first
+ * one is for stored blocks of 16383 bytes (memLevel == 8), whereas the second
+ * is for stored blocks of 127 bytes (the worst case memLevel == 1). The
+ * expansion results from five bytes of header for each stored block.
  *
- * This function could be more sophisticated to provide closer upper bounds for
- * every combination of windowBits and memLevel.  But even the conservative
- * upper bound of about 14% expansion does not seem onerous for output buffer
- * allocation.
+ * The larger expansion of 13% results from a window size less than or equal to
+ * the symbols buffer size (windowBits <= memLevel + 7). In that case some of
+ * the data being compressed may have slid out of the sliding window, impeding
+ * a stored block from being emitted. Then the only choice is a fixed or
+ * dynamic block, where a fixed block limits the maximum expansion to 9 bits
+ * per 8-bit byte, plus 10 bits for every block. The smallest block size for
+ * which this can occur is 255 (memLevel == 2).

-    available in the animation framework are also available in \l{Qt Quick},
-    where it offers a declarative way of defining animations. Much of the
-    knowledge acquired about the animation framework can be applied to
-    \l{Qt Quick}.
-
-    In this overview, we explain the basics of its architecture. We

+    \section1 The Animation architecture
 
-    We will in this section take a high-level look at the animation
-    framework's architecture and how it is used to animate Qt
-    properties. The following diagram shows the most important classes
-    in the animation framework.
+    The following diagram shows the most important classes provided by the
+    framework:
 
     \image animations-architecture.png
 
-    The animation framework foundation consists of the base class
-    QAbstractAnimation, and its two subclasses QVariantAnimation and
-    QAnimationGroup. QAbstractAnimation is the ancestor of all
-    animations. It represents basic properties that are common for all
-    animations in the framework; notably, the ability to start, stop,
-    and pause an animation. It is also receives the time change
-    notifications.
-
-    The animation framework further provides the QPropertyAnimation
-    class, which inherits QVariantAnimation and performs animation of
-    a Qt property, which is part of Qt's \l{Meta-Object
-    System}{meta-object system}. The class performs an interpolation
-    over the property using an easing curve. So when you want to
-    animate a value, you can declare it as a property and make your
-    class a QObject. Note that this gives us great freedom in
-    animating already existing widgets and other \l{QObject}s.
+    It includes the QAbstractAnimation class, which provides the
+    necessary foundation for animations. This class defines the
+    generic properties for all animations supported by the framework.
+    For example, the ability to start, stop, and pause an animation. The
+    class also receives the time change notifications.
+
+    The framework further provides the QVariantAnimation and
+    QAnimationGroup classes, which build on their base case, QAbstractAnimation.
+    Next in the hierarchy is QPropertyAnimation, which is derived from
+    QVariantAnmiation, and it lets you animate a Qt property of a widget or
+    QObject. The class performs interpolation on the property value using an
+    easing curve. With these in place, you just need a QObject class with a
+    Qt property value that you can animate.
+
+    \note It is required that the target object you are animating is a QObject
+    or its subclass. This is necessary as the animation framework depends on the
+    \l{Meta-Object System}{meta-object system} for all the information about the
+    object it is animating.
 
     Complex animations can be constructed by building a tree structure
-    of \l{QAbstractAnimation}s. The tree is built by using
-    \l{QAnimationGroup}s, which function as containers for other
-    animations. Note also that the groups are subclasses of
-    QAbstractAnimation, so groups can themselves contain other groups.
+    of \l{QAbstractAnimation}s, where the tree is a QAnimationGroup that
+    contains other animations. These animation groups can also contain
+    subgroups representing different groups or animations, such as
+    QParallelAnimationGroup and QSequentialAnimationGroup.
 
-    Behind the scenes, the animations are controlled by a global
-    timer, which sends \l{QAbstractAnimation::updateCurrentTime()}{updates} to
-    all animations that are playing.
+    Behind the scenes, all animations are controlled by a global
+    timer, which sends \l{QAbstractAnimation::updateCurrentTime()}{updates} about

-    For detailed descriptions of the classes' function and roles in
-    the framework, please look up their class descriptions.
+    For detailed information of these individual classes' and their roles in

-    \section1 Animating Qt Properties
+    \section1 Animating Qt properties
 
-    As mentioned in the previous section, the QPropertyAnimation class can
-    interpolate over Qt properties. It is often this class that should be used
-    for animation of values; in fact, its superclass, QVariantAnimation, has an
-    empty implementation of \l{QVariantAnimation::}{updateCurrentValue()}, and
-    does not change any value unless we change it ourselves on the
+    As the QPropertyAnimation class can interpolate on Qt properties, it is
+    used often. In fact, its superclass---QVariantAnimation---provides an
+    abstract implementation of \l{QVariantAnimation::}{updateCurrentValue()},
+    which does not change any value unless you change it on the
     \l{QVariantAnimation::valueChanged()}{valueChanged signal}.
 
-    A major reason we chose to animate Qt properties is that it
-    presents us with freedom to animate already existing classes in
-    the Qt API. Notably, the QWidget class (which we can also embed in
-    a QGraphicsView) has properties for its bounds, colors, etc.
-    Let's look at a small example:
-
-    \code
-        QPushButton button("Animated Button");
-        button.show();
+    The framework lets you animate the Qt properties of the existing
+    classes in Qt. For example, the QWidget class---can be embedded in
+    a QGraphicsView---has properties for its bounds, colors, and so on.
+    The following example demonstrates how you can animate a QPushButton
+    widget:
 
-        QPropertyAnimation animation(&button, "geometry");
-        animation.setDuration(10000);
-        animation.setStartValue(QRect(0, 0, 100, 30));
-        animation.setEndValue(QRect(250, 250, 100, 30));
+    \snippet code/src_corelib_animation_qpropertyanimation.cpp 0
 
-        animation.start();
-    \endcode
+    The example animates the \c pos Qt property of a QPushButton, to move
+    it from the top--left corner of the screen to the end position (250, 250),
+    in 10 seconds (10000 milliseconds).
 
-    This code will move \c button from the top left corner of the
-    screen to the position (250, 250) in 10 seconds (10000 milliseconds).
-
-    The example above will do a linear interpolation between the
-    start and end value. It is also possible to set values
-    situated between the start and end value. The interpolation
-    will then go by these points.
+    It uses the linear interpolation method to control the speed of
+    animation between the start and end values. Try adding another value
+    in--between the start and end value to see how they are interpolated.
+    This time use the QPropertyAnimation::setKeyValueAt function to add
+    these values:
 
     \code
-        QPushButton button("Animated Button");
-        button.show();
-
-        QPropertyAnimation animation(&button, "geometry");
-        animation.setDuration(10000);
-
-        animation.setKeyValueAt(0, QRect(0, 0, 100, 30));
-        animation.setKeyValueAt(0.8, QRect(250, 250, 100, 30));
-        animation.setKeyValueAt(1, QRect(0, 0, 100, 30));
-
-        animation.start();
+        ...
+        anim->setDuration(10000);
+        anim->setKeyValueAt(0, QPoint(0, 0));
+        anim->setKeyValueAt(0.8, QPoint(250, 250));
+        anim->setKeyValueAt(1, QPoint(0, 0));
+        ...
     \endcode
 
-    In this example, the animation will take the button to (250, 250)
-    in 8 seconds, and then move it back to its original position in
-    the remaining 2 seconds. The movement will be linearly
-    interpolated between these points.
+    In this example, the animation moves the button to
+    (250, 250) in 8 seconds, and moves it back to its original position in
+    the remaining 2 seconds. The button's movement is linear-interpolated
+    between these points.
+
+    You can also animate a QObject's value that is not declared as a Qt
+    property, if the value has a setter method. In such cases, derive
+    a new class from the class that contains the value, and add a Qt property
+    for that value with the setter.
 
-    You also have the possibility to animate values of a QObject
-    that is not declared as a Qt property. The only requirement is
-    that this value has a setter. You can then subclass the class
-    containing the value and declare a property that uses this setter.
-    Note that each Qt property requires a getter, so you will need to
-    provide a getter yourself if this is not defined.

     \section1 Animations and the Graphics View Framework
 
-    When you want to animate \l{QGraphicsItem}s, you also use
-    QPropertyAnimation. However, QGraphicsItem does not inherit QObject.
-    A good solution is to subclass the graphics item you wish to animate.
-    This class will then also inherit QObject.
-    This way, QPropertyAnimation can be used for \l{QGraphicsItem}s.
-    The example below shows how this is done. Another possibility is
-    to inherit QGraphicsWidget, which already is a QObject.
+    QPropertyAnimation can also be used to animate a QGraphicsItem, which does
+    not inherit QObject. In such cases, you derive a class from the graphics
+    item that you want to animate. This derived class should also inherit form
+    QObject to enable using QPropertyAnimation on a QGraphicsItem. The
+    following example shows how this is done:

-    As described in the previous section, we need to define

-    As mentioned, QPropertyAnimation performs an interpolation between

-    values to the animation, you can also use an easing curve. Easing
-    curves describe a function that controls how the speed of the

-    want to control the speed of an animation without changing the

+    An application often contains more than one animation. For
+    example, it wants to move more than one graphics item
     simultaneously or move them in sequence after each other.
 
-    The subclasses of QAnimationGroup (QSequentialAnimationGroup and
-    QParallelAnimationGroup) are containers for other animations so
+    The subclasses of QAnimationGroup---QSequentialAnimationGroup and
+    QParallelAnimationGroup---are containers for other animations so
     that these animations can be animated either in sequence or
-    parallel. The QAnimationGroup is an example of an animation that
-    does not animate properties, but it gets notified of time changes
-    periodically. This enables it to forward those time changes to its
-    contained animations, and thereby controlling when its animations
-    are played.
-
-    Let's look at code examples that use both
-    QSequentialAnimationGroup and QParallelAnimationGroup, starting
-    off with the latter.
-
-    \code
-        QPushButton *bonnie = new QPushButton("Bonnie");
-        bonnie->show();
+    parallel. The QAnimationGroup does not animate properties, but it
+    gets notified of time changes periodically. This enables it to
+    forward those time changes to the animation groups, which control when
+    their animations are played.
 
-        QPushButton *clyde = new QPushButton("Clyde");
-        clyde->show();
+    The two following examples demonstrate the use of both
+    QSequentialAnimationGroup and QParallelAnimationGroup:
 
-        QPropertyAnimation *anim1 = new QPropertyAnimation(bonnie, "geometry");
-        // Set up anim1
-
-        QPropertyAnimation *anim2 = new QPropertyAnimation(clyde, "geometry");
-        // Set up anim2
-
-        QParallelAnimationGroup *group = new QParallelAnimationGroup;
-        group->addAnimation(anim1);
-        group->addAnimation(anim2);
-
-        group->start();
-    \endcode

-    Since an animation group is an animation itself, you can add
-    it to another group. This way, you can build a tree structure
-    of animations which specifies when the animations are played
-    in relation to each other.

+    \title CBOR Support in Qt
+    \ingroup qt-basic-concepts
+    \brief An overview of CBOR support in Qt.
+
+    \ingroup frameworks-technologies
+
+    \keyword CBOR
+
+    Qt provides support for dealing with CBOR data. CBOR is a binary format to
+    store data that has a superset of the types available in JSON, but is more
+    compact.
+
+    The CBOR support in Qt provides an easy to use C++ API to parse,
+    modify and save CBOR data.
+
+    More details about the CBOR data format can be found in \l {RFC 7049}.
+
+    \tableofcontents
+
+    \section1 Overview
+
+    CBOR is a format to store structured data. It has three groups of built-in types:
+
+    \list
+    \li Basic types: integers, floating point, boolean, null, etc.
+    \li String-like types: strings and byte arrays
+    \li Containers: arrays and maps
+    \endlist
+
+    In addition, CBOR can add a "tag" to extend the meaning of the type. The
+    container types can contain basic types, string-like types and containers.
+
+    \sa {Cbordump Example}, {Convert Example}, {JSON Save Game Example}
+
+    \section1 The CBOR Classes
+
+    \section2 The QCborValue Class
+
+    The QCborValue class represents any CBOR type. It also has a simple API for
+    reading and writing to QCborStreamReader and QCborStreamWriter objects, as
+    well as manipulating such objects in memory, with the help of QCborArray
+    and QCborMap. The CborValue API is simplified from the full CBOR data type
+    and always represents all integers as \l qint64 and all floating-point as
+    \c double. This means QCborValue is unable to represent CBOR integer values
+    outside of the range of \l qint64 (-2^63 to 2^63-1). When creating a CBOR
+    stream, QCborValue::toCbor() can be configured to attempt to write the
+    shorter single- and half-precision floating-point representations.
+
+    \section2 The QCborArray Class
+
+    The QCborArray class is used to hold an array of QCborValue objects. A
+    QCborValue object can contain a QCborArray object. It has functions for
+    converting to and from QVariantList, QStringList, QJsonArray.
+
+    \section2 The QCborMap Class
+
+    The QCborMap class is used to hold an map of QCborValue objects. A
+    QCborValue object can contain a QCborMap object. It has functions for
+    converting to and from QVariantMap, QVariantMap, and QJsonObject, but it
+    can have keys of any type, not just QString.
+
+    \section2 The QCborStreamReader Class
+
+    The QCborStreamReader class is a low level API for reading CBOR data from a
+    QIODevice, a QByteArray, or a pointer to memory. It has an API similar to
+    the QXmlStreamReader class.
+
+    \section2 The QCborStreamWriter Class
+
+    The QCborStreamWriter class is a low level API for writing CBOR data to a
+    QIODevice or a QByteArray. It has an API similar to the QXmlStreamWriter
+    class.

+\cmakevariablesince 6.4.2

+\cmakevariableandroidonly
+
+The \c{QT_ANDROID_MULTI_ABI_FORWARD_VARS} variable allows specifying the list of
+CMake variables that need to be forwarded from the main ABI project to
+ABI-specific subprojects. Due to the specifics of the Multi-ABI project build
+process, there is no generic way to forward the CMake cache variables
+that are specified either in the command line or in another similar way.
+
+A typical use case for the variable is propagating CMake cache variables
+specified in the command line. For example, a project has two variables
+\c{PROJECT_WIDE_VARIABLE1} and \c{PROJECT_WIDE_VARIABLE2} that affect the
+project configuration:
+\badcode
+cmake_minimum_required(VERSION 3.18)
+
+project(MyProject LANGUAGES CXX)
+
+find_package(Qt6 REQUIRED COMPONENTS Core)
+
+qt_add_executable(MyApp main.cpp)
+
+if(PROJECT_WIDE_VARIABLE1)
+    target_sources(MyApp PRIVATE sourcefile1.cpp)
+endif()
+if(PROJECT_WIDE_VARIABLE2)
+    target_sources(MyApp PRIVATE sourcefile2.cpp)
+endif()
+\endcode
+
+The above contents of \c{CMakeLists.txt} enable you to control how
+\c{MyApp} is built by setting the corresponding CMake variables from the
+command line:
+\badcode
+qt-cmake -S<source directory> -B<build directory> \
+    -DPROJECT_WIDE_VARIABLE1=ON \
+    -DPROJECT_WIDE_VARIABLE2=ON \
+    -DQT_ANDROID_MULTI_ABI_FORWARD_VARS="PROJECT_WIDE_VARIABLE1;PROJECT_WIDE_VARIABLE2"
+\endcode
+
+When configuring the application for desktop, \c{PROJECT_WIDE_VARIABLE1} and
+\c{PROJECT_WIDE_VARIABLE2} are visible in CMake listings and scripts as global
+cache variables. This doesn't work for Android Multi-ABI builds because
+ABI-specific subprojects do not inherit the cache variables from the main-ABI
+project. This issue can be solved by passing the list of required variables to
+the \c{QT_ANDROID_MULTI_ABI_FORWARD_VARS} variable, so both
+\c{PROJECT_WIDE_VARIABLE1} and \c{PROJECT_WIDE_VARIABLE2} values will be
+propagated to the ABI-specific builds.
+
+The variable can be also defined in the project's CMakeLists.txt:
+\badcode
+...
+qt_add_executable(MyApp main.cpp)
+...
+if(ANDROID)
+    set(QT_ANDROID_MULTI_ABI_FORWARD_VARS "PROJECT_WIDE_VARIABLE1;PROJECT_WIDE_VARIABLE2")
+endif()
+...
+\endcode
+
+Setting the variable in this way allows you to have a predefined set of
+variables that will always be forwarded to abi-specific projects.
+
+\note The forwarding is done in the target finalizer, which is implicitly
+called when \l{qt6_add_executable}{qt_add_executable()} is used. The
+finalization occurs automatically when using CMake 3.19 or later.

 After a target is created, further processing or \e{finalization} steps are
 commonly needed. The steps to perform depend on the platform and on various
-properties of the target. The finalization processing is implemented by the
-\l{qt6_finalize_target}{qt_finalize_target()} command. You might need to also
-call the \l{qt6_finalize_project}{qt_finalize_project()} command at the end
-of top-level CMakeLists.txt to correctly resolve the dependencies between
-project targets.

-Finalization can occur either as part of this call or be deferred to sometime
-after this command returns (but it should still be in the same directory scope).
-When using CMake 3.19 or later, finalization is automatically deferred to the
+properties of the target.

+The finalization processing is implemented by two commands:
+\l{qt6_finalize_target}{qt_finalize_target()} and
+\l{qt6_finalize_project}{qt_finalize_project()}.

+Target finalization can occur either as part of calling \c{qt_add_executable}
+or be deferred to sometime after this command returns (but it should still be in
+the same directory scope).
+
+When using CMake 3.19 or later, target finalization is automatically deferred to the
 end of the current directory scope. This gives the caller an opportunity to
 modify properties of the created target before it is finalized. When using
 CMake versions earlier than 3.19, automatic deferral isn't supported. In that
-case, finalization is performed immediately before this command returns.
+case, target finalization is performed immediately before this command returns.
 
 Regardless of the CMake version, the \c{MANUAL_FINALIZATION} keyword can be given to
 indicate that you will explicitly call \l{qt6_finalize_target}{qt_finalize_target()}
 yourself instead at some later time. In general, \c MANUAL_FINALIZATION should
 not be needed unless the project has to support CMake 3.18 or earlier.
 
+Project finalization occurs automatically when using CMake 3.19 or later.
+When using an older CMake version, you should call

+    \title Qt Serialization
+    \brief Serializations provided by Qt API
+
+    The purpose of serialization is to save the state of an object to be able to
+    recreate it when needed. It allows you to perform actions like:
+
+    \list
+        \li Sending the object to a remote application by using a web service
+        \li Passing the object as a JSON or XML string
+        \li Saving and restoring user information or sharing it across applications
+    \endlist
+
+    The Qt API provides support for serialization for several use cases:
+
+    \list
+    \li \l JSON support in Qt provides an easy to use C++ API to parse, modify
+           and save JSON data. \l {CBOR} {CBOR Support in Qt} is a compact form
+           of binary data encoding that is a superset of JSON.
+    \li \l QDataStream provides serialization of binary data to a QIODevice
+    \li \l {Qt XML C++ Classes} provide C++ implementations of the \l XML Streaming
+           and DOM standards for XML
+    \li \l CBOR is Qt's implementation for the CBOR serialization format.
+    \li \l QSettings provides a way of serializing and storing platform independent
+           application settings.
+    \endlist
+
+    \section1 Advantages of JSON and CBOR
+
+    When you use \l JSON information is stored in a QJsonObject and a QJsonDocument
+    takes care to stream values into a QByteArray.
+
+    For example
+    \code
+        QJsonObject jobject;
+        jobject["SensorID"] = m_id;
+        jobject["AmbientTemperature"] = m_ambientTemperature;
+        jobject["ObjectTemperature"] = m_objectTemperature;
+        jobject["AccelerometerX"] = m_accelerometerX;
+        jobject["AccelerometerY"] = m_accelerometerY;
+        jobject["AccelerometerZ"] = m_accelerometerZ;
+        jobject["Altitude"] = m_altitude;
+        jobject["Light"] = m_light;
+        jobject["Humidity"] = m_humidity;
+        QJsonDocument doc( jobject );
+
+        return doc.toJson();
+    \endcode
+
+    JSON has several advantages:
+
+    \list
+    \li Textual JSON is declarative, which makes it readable to humans
+    \li The information is structured
+    \li Exchanging generic information is easy
+    \li JSON allows extending messages with additional values
+    \li Many solutions exist to receive and parse JSON in cloud-based solutions
+    \endlist
+
+    \l CBOR is the Concise Binary Object Representation, a very compact form of
+    binary data encoding that is a superset of JSON. It was created by the IETF
+    Constrained RESTful Environments (CoRE) WG, which has been used in many new
+    RFCs. CBOR shares many of the advantages of JSON, but sacrifices human
+    readability for compactness.
+
+    \section1 Advantages of QDataStream Classes
+
+    \l QDataStream is a viable option when the whole flow of data is determined
+    and not about to change. In addition, both the reader and the writer of the
+    data must be written in Qt.
+
+    Adding support for this to a class requires two additional operators.
+    For example, for a class named SensorInformation:
+
+    \code
+    QDataStream &operator<<(QDataStream &, const SensorInformation &);
+    QDataStream &operator>>(QDataStream &, SensorInformation &);
+    \endcode
+
+    The implementation for the serialization is shown below:
+
+    \code
+    QDataStream &operator<<(QDataStream &out, const SensorInformation &item)
+    {
+        QDataStream::FloatingPointPrecision prev = out.floatingPointPrecision();
+        out.setFloatingPointPrecision(QDataStream::DoublePrecision);
+        out << item.m_id
+            << item.m_ambientTemperature
+            << item.m_objectTemperature
+            << item.m_accelerometerX
+            << item.m_accelerometerY
+            << item.m_accelerometerZ
+            << item.m_altitude
+            << item.m_light
+            << item.m_humidity;
+        out.setFloatingPointPrecision(prev);
+        return out;
+    }
+    \endcode
+
+    Deserialization works similarly, but using the \c {>>} operator.
+    For example, \c {out >> item.m_id}, and so on.
+
+    Usually, using QDataStream is faster than using textual JSON.
+
+    \section1 Advantages of Qt XML C++ Classes
+
+    Qt provides the QDomDocument class that represents the XML document and
+    two classes for reading and writing the XML through a simple streaming API:
+    QXmlStreamReader and QXmlStreamWriter.
+
+    QDomDocument class represents the entire XML document. It is the root of the
+    document tree and provides primary access to the document's data.
+
+    A stream reader reports an XML document as a stream of tokens. This differs
+    from SAX as SAX applications provide handlers to receive XML events from the
+    parser, whereas the QXmlStreamReader drives the loop, pulling tokens from the
+    reader when they are needed. This pulling approach makes it possible to build
+    recursive descent parsers, allowing XML parsing code to be split into
+    different methods or classes.
+
+    QXmlStreamReader a parser for well-formed XML 1.0, excluding external parsed
+    entities. Hence, data provided to the stream reader adheres to the
+    W3C's criteria for well-formed XML, or an error will be raised. Functions
+    such as \c atEnd(), \c error(), and \c hasError() can be used to test  for
+    such errors and obtain a description of them.
+
+    The QXmlStreamWriter is a streaming API that takes care of prefixing namespaces,
+    when the namespaceUri is specified when writing elements or attributes.

+    Calls \a v with either a QUtf8StringView, QLatin1String, or QStringView, depending
+    on the encoding of the string data this string-view references.
+
+    This is how most functions taking QAnyStringView fork off into per-encoding
+    functions:
+
+    \code
+    void processImpl(QLatin1String s) { ~~~ }
+    void processImpl(QUtf8StringView s) { ~~~ }
+    void processImpl(QStringView s) { ~~~ }

+    void process(QAnyStringView s)
+    {
+        s.visit([](auto s) { processImpl(s); });
+    }
+    \endcode
+
+    Here, we're reusing the same name, \c s, for both the QAnyStringView
+    object, as well as the lambda's parameter. This is idiomatic code and helps
+    track the identity of the objects through visit() calls, for example in more
+    complex situations such as
+
+    \code
+    bool equal(QAnyStringView lhs, QAnyStringView rhs)
+    {
+        // assuming operator==(QAnyStringView, QAnyStringView) didn't, yet, exist:
+        return lhs.visit([rhs](auto lhs) {
+            rhs.visit([lhs](auto rhs) {
+                return lhs == rhs;
+            });
+        });
+    }
+    \endcode
+
+    visit() requires that all lambda instantiations have the same return type.
+    If they differ, you get a compile error, even if there is a common type. To
+    fix, you can use explicit return types on the lambda, or cast in the return
+    statements:
+
+    \code
+    // wrong:
+    QAnyStringView firstHalf(QAnyStringView input)
+    {
+        return input.visit([](auto input) {   // ERROR: lambdas return different types
+            return input.sliced(0, input.size() / 2);
+        });
+    }
+    // correct:
+    QAnyStringView firstHalf(QAnyStringView input)
+    {
+        return input.visit([](auto input) -> QAnyStringView { // OK, explicit return type
+            return input.sliced(0, input.size() / 2);
+        });
+    }
+    // also correct:

+    \section1 Increasing Test Function Timeout
+
+    QtTest limits the run-time of each test to catch infinite loops and similar
+    bugs. By default, any test function call will be interrupted after five
+    minutes. For data-driven tests, this applies to each call with a distinct
+    data-tag. This timeout can be configured by setting the \c QTEST_FUNCTION_TIMEOUT
+    environment variable to the maximum number of milliseconds that is acceptable
+    for a single call to take. If a test takes longer than the configured timeout,
+    it is interrupted, and \c qFatal() is called. As a result, the test aborts by
+    default, as if it had crashed.
+
+    To set \c QTEST_FUNCTION_TIMEOUT from the command line on Linux or macOS, enter:
+
+    \badcode
+    QTEST_FUNCTION_TIMEOUT=900000
+    export QTEST_FUNCTION_TIMEOUT
+    \endcode
+
+    On Windows:
+    \badcode
+    SET QTEST_FUNCTION_TIMEOUT=900000
+    \endcode
+
+    Then run the test inside this environment.
+
+    Alternatively, you can set the environment variable programmatically in the
+    test code itself, for example by calling, from the
+    \l{Creating a Test}{initMain()} special method of your test class:
+
+    \badcode
+    qputenv("QTEST_FUNCTION_TIMEOUT", "900000");
+    \endcode
+
+    To calculate a suitable value for the timeout, see how long the test usually
+    takes and decide how much longer it can take without that being a symptom of
+    some problem. Convert that longer time to milliseconds to get the timeout value.
+    For example, if you decide that a test that takes several minutes could
+    reasonably take up to twenty minutes, for example on a slow machine,
+    multiply \c{20 * 60 * 1000 = 1200000} and set the environment variable to
+    \c 1200000 instead of the \c 900000 above.

+This package contains sources for a webpage whose scripts run batched WASM tests - a single
+executable with a number of linked test classes.
+The webpage operates on an assumption that the test program, when run without arguments,
+prints out a list of test classes inside its module. Then, when run with the first argument
+equal to the name of one of the test classes, the test program will execute all tests within
+that single class.
+
+The scripts in the page will load the wasm file called 'test_batch.wasm' with its corresponding
+js script 'test_batch.js'.
+
+Public interface for querying the test execution status is accessible via the global object
+'qtTestRunner':
+
+qtTestRunner.status - this contains the status of the test runner itself, of the enumeration type
+RunnerStatus.
+
+qtTestRunner.results - a map of test class name to test result. The result contains a test status
+(status, of the enumeration TestStatus), and in case of a terminal status, also the test's exit code
+(exitCode) and xml text output (textOutput), if available.
+
+qtTestRunner.onStatusChanged - an event for changes in state of the runner itself. The possible
+values are those of the enumeration RunnerStatus.
+
+qtTestRunner.onTestStatusChanged - an event for changes in state of a single tests class. The
+possible values are those of the enumeration TestStatus. When a terminal state is reached
+(Completed, Error, Crashed), the text results and exit code are filled in, if available, and
+will not change.
+
+Typical usage:
+Run all tests in a batch:
+    - load the webpage batchedtestrunner.html
+
+Run a single test in a batch:
+    - load the webpage batchedtestrunner.html?qtestname=tst_mytest
+
+Query for test execution state:
+    - qtTestRunner.onStatusChanged.addEventListener((runnerStatus) => (...)))
+    - qtTestRunner.onTestStatusChanged.addEventListener((testName, status) => (...))
+    - qtTestRunner.status === (...)
+    - qtTestRunner.results['tst_mytest'].status === (...)
+    - qtTestRunner.results['tst_mytest'].textOutput
