Windows XP is not a supported platform, but all newer Windows should be able to build OpenJDK.
On Windows, it is important that you pay attention to the instructions in the Special Considerations.
Windows is the only non-POSIX OS supported by OpenJDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. For OpenJDK 9, the only supported such layer is Cygwin. (Msys is no longer supported due to a too old bash; msys2 and the new Windows Subsystem for Linux (WSL) would likely be possible to support in a future version but that would require a community effort to implement.)
-Internally in the build system, all paths are represented as Unix-style paths, e.g. /cygdrive/c/hg/jdk9/Makefile rather than C:\hg\jdk9\Makefile. This rule also applies to input to the build system, e.g. in arguments to configure. So, use --with-freetype=/cygdrive/c/freetype rather than --with-freetype=c:\freetype. For details on this conversion, see the section on Fixpath.

Cygwin
A functioning Cygwin environment is thus required for building OpenJDK on Windows. If you have a 64-bit OS, we strongly recommend using the 64-bit version of Cygwin.
Note: Cygwin has a model of continuously updating all packages without any easy way to install or revert to a specific version of a package. This means that whenever you add or update a package in Cygwin, you might (inadvertently) update tools that are used by the OpenJDK build process, and that can cause unexpected build problems.

If a required library is not detected by configure, you need to provide the path to it. There are two forms of the configure arguments to point to an external library: --with-<LIB>=<path> or --with-<LIB>-include=<path to include> --with-<LIB>-lib=<path to lib>. The first variant is more concise, but require the include files an library files to reside in a default hierarchy under this directory. In most cases, it works fine.
As a fallback, the second version allows you to point to the include directory and the lib directory separately.

+### FreeType Notice
+
+```
+FreeType comes with two licenses from which you can choose the one
+which fits your needs best.
+
+ The FreeType License (FTL) is the most commonly used one. It is
+ a BSD-style license with a credit clause and thus compatible with
+ the GNU Public License (GPL) version 3, but not with the
+ GPL version 2.
+
+ The GNU General Public License (GPL), version 2. Use it for all
+ projects which use the GPLv2 also, or which need a license
+ compatible to the GPLv2.

+ The FreeType Project LICENSE
+ ----------------------------
+
+ 2006-Jan-27
+
+ Copyright 1996-2002, 2006 by
+ David Turner, Robert Wilhelm, and Werner Lemberg
+
+
+
+Introduction
+============
+
+ The FreeType Project is distributed in several archive packages;
+ some of them may contain, in addition to the FreeType font engine,
+ various tools and contributions which rely on, or relate to, the
+ FreeType Project.
+
+ This license applies to all files found in such packages, and
+ which do not fall under their own explicit license. The license
+ affects thus the FreeType font engine, the test programs,
+ documentation and makefiles, at the very least.
+
+ This license was inspired by the BSD, Artistic, and IJG
+ (Independent JPEG Group) licenses, which all encourage inclusion
+ and use of free software in commercial and freeware products
+ alike. As a consequence, its main points are that:
+
+ o We don't promise that this software works. However, we will be
+ interested in any kind of bug reports. (`as is' distribution)
+
+ o You can use this software for whatever you want, in parts or
+ full form, without having to pay us. (`royalty-free' usage)
+
+ o You may not pretend that you wrote this software. If you use
+ it, or only parts of it, in a program, you must acknowledge
+ somewhere in your documentation that you have used the
+ FreeType code. (`credits')
+
+ We specifically permit and encourage the inclusion of this
+ software, with or without modifications, in commercial products.
+ We disclaim all warranties covering The FreeType Project and
+ assume no liability related to The FreeType Project.
+
+
+ Finally, many people asked us for a preferred form for a
+ credit/disclaimer to use in compliance with this license. We thus
+ encourage you to use the following text:
+
+ """
+ Portions of this software are copyright © The FreeType
+ Project (www.freetype.org). All rights reserved.
+ """
+
+ Please replace with the value from the FreeType version you
+ actually use.
+
+
+Legal Terms
+===========
+
+0. Definitions
+--------------
+
+ Throughout this license, the terms `package', `FreeType Project',
+ and `FreeType archive' refer to the set of files originally
+ distributed by the authors (David Turner, Robert Wilhelm, and
+ Werner Lemberg) as the `FreeType Project', be they named as alpha,
+ beta or final release.
+
+ `You' refers to the licensee, or person using the project, where
+ `using' is a generic term including compiling the project's source
+ code as well as linking it to form a `program' or `executable'.
+ This program is referred to as `a program using the FreeType
+ engine'.
+
+ This license applies to all files distributed in the original
+ FreeType Project, including all source code, binaries and
+ documentation, unless otherwise stated in the file in its
+ original, unmodified form as distributed in the original archive.
+ If you are unsure whether or not a particular file is covered by
+ this license, you must contact us to verify this.
+
+ The FreeType Project is copyright (C) 1996-2000 by David Turner,
+ Robert Wilhelm, and Werner Lemberg. All rights reserved except as
+ specified below.
+
+1. No Warranty
+--------------
+
+ THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY
+ KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+ WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
+ BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
+ USE, OF THE FREETYPE PROJECT.
+
+2. Redistribution
+-----------------
+
+ This license grants a worldwide, royalty-free, perpetual and
+ irrevocable right and license to use, execute, perform, compile,
+ display, copy, create derivative works of, distribute and
+ sublicense the FreeType Project (in both source and object code
+ forms) and derivative works thereof for any purpose; and to
+ authorize others to exercise some or all of the rights granted
+ herein, subject to the following conditions:
+
+ o Redistribution of source code must retain this license file
+ (`FTL.TXT') unaltered; any additions, deletions or changes to
+ the original files must be clearly indicated in accompanying
+ documentation. The copyright notices of the unaltered,
+ original files must be preserved in all copies of source
+ files.
+
+ o Redistribution in binary form must provide a disclaimer that
+ states that the software is based in part of the work of the
+ FreeType Team, in the distribution documentation. We also
+ encourage you to put an URL to the FreeType web page in your
+ documentation, though this isn't mandatory.
+
+ These conditions apply to any software derived from or based on
+ the FreeType Project, not just the unmodified files. If you use
+ our work, you must acknowledge us. However, no fee need be paid
+ to us.
+
+3. Advertising
+--------------
+
+ Neither the FreeType authors and contributors nor you shall use
+ the name of the other for commercial, advertising, or promotional
+ purposes without specific prior written permission.
+
+ We suggest, but do not require, that you use one or more of the
+ following phrases to refer to this software in your documentation
+ or advertising materials: `FreeType Project', `FreeType Engine',
+ `FreeType library', or `FreeType Distribution'.
+
+ As you have not signed this license, you are not required to
+ accept it. However, as the FreeType Project is copyrighted
+ material, only this license, or another one contracted with the
+ authors, grants you the right to use, distribute, and modify it.
+ Therefore, by using, distributing, or modifying the FreeType
+ Project, you indicate that you understand and accept all the terms
+ of this license.
+
+4. Contacts
+-----------
+
+ There are two mailing lists related to FreeType:
+
+ o freetype@nongnu.org
+
+ Discusses general use and applications of FreeType, as well as
+ future and wanted additions to the library and distribution.
+ If you are looking for support, start in this list if you
+ haven't found anything to help you in the documentation.
+
+ o freetype-devel@nongnu.org
+
+ Discusses bugs, as well as engine internals, design issues,
+ specific licenses, porting, etc.

+### GPL v2
+
+```
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) 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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+ 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
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ 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 2 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, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ , 1 April 1989
+ Ty Coon, President of Vice
+
+This 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 Library General
+Public License instead of this License.

+Tips and tasks when updating freetype sources to a newer version.
+-----------------------------------------------------------------
+
+The freetype sources here are just the subset needed by JDK. This is deliberate.
+When updating be sure to import only the same files.
+If a file is no longer present in freetype, or renamed this will be noticed
+during the copy.
+Occasionally there may be a new missing dependency if freetype introduces
+a new file or imports a file into these files that was not previously used.
+Import just what is needed.
+
+Before attempting compilation be sure to diff the JDK copy and the freetype copy
+of src/java.desktop/share/native/libfreetype/include/freetype/config/ftoption.h
+and re-apply the same edits made for the JDK option file.
+Notably JDK is not using GZIP or LZW or BDF support which are on by default
+for the freetype distribution.
+If you don't make the edits the build will fail due to not copying the relevant
+sources.
+
+Use "expand" and "sed" to remove tabs and trailing white space from the imported
+sources. The current version of freetype is quite clean in this respect.
+./src/base/md5.h and ./src/base/md5.c are the only files with tabs,
+and ./include/freetype/ftdriver.h has the only trailing white space.
+If you forget this step, or aren't thorough, jcheck will remind you.
+
+Remember to update the freetype version identified in
+src/java.desktop/share/legal/freetype.md

+ *
+ * @enum:
+ * FT_LOAD_XXX
+ *
+ * @description:
+ * A list of bit field constants for @FT_Load_Glyph to indicate what
+ * kind of operations to perform during glyph loading.
+ *
+ * @values:
+ * FT_LOAD_DEFAULT ::
+ * Corresponding to~0, this value is used as the default glyph load
+ * operation. In this case, the following happens:
+ *
+ * 1. FreeType looks for a bitmap for the glyph corresponding to the
+ * face's current size. If one is found, the function returns.
+ * The bitmap data can be accessed from the glyph slot (see note
+ * below).
+ *
+ * 2. If no embedded bitmap is searched for or found, FreeType looks
+ * for a scalable outline. If one is found, it is loaded from
+ * the font file, scaled to device pixels, then `hinted' to the
+ * pixel grid in order to optimize it. The outline data can be
+ * accessed from the glyph slot (see note below).
+ *
+ * Note that by default the glyph loader doesn't render outlines into
+ * bitmaps. The following flags are used to modify this default
+ * behaviour to more specific and useful cases.
+ *
+ * FT_LOAD_NO_SCALE ::
+ * Don't scale the loaded outline glyph but keep it in font units.
+ *
+ * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
+ * unsets @FT_LOAD_RENDER.
+ *
+ * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
+ * FT_LOAD_NO_SCALE usually yields meaningless outlines because the
+ * subglyphs must be scaled and positioned with hinting instructions.
+ * This can be solved by loading the font without FT_LOAD_NO_SCALE and
+ * setting the character size to `font->units_per_EM'.
+ *
+ * FT_LOAD_NO_HINTING ::
+ * Disable hinting. This generally generates `blurrier' bitmap glyphs
+ * when the glyph are rendered in any of the anti-aliased modes. See
+ * also the note below.
+ *
+ * This flag is implied by @FT_LOAD_NO_SCALE.
+ *
+ * FT_LOAD_RENDER ::
+ * Call @FT_Render_Glyph after the glyph is loaded. By default, the
+ * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
+ * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
+ *
+ * This flag is unset by @FT_LOAD_NO_SCALE.
+ *
+ * FT_LOAD_NO_BITMAP ::
+ * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
+ * flag.
+ *
+ * @FT_LOAD_NO_SCALE always sets this flag.
+ *
+ * FT_LOAD_VERTICAL_LAYOUT ::
+ * Load the glyph for vertical text layout. In particular, the
+ * `advance' value in the @FT_GlyphSlotRec structure is set to the
+ * `vertAdvance' value of the `metrics' field.
+ *
+ * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
+ * this flag currently. Reason is that in this case vertical metrics
+ * get synthesized, and those values are not always consistent across
+ * various font formats.
+ *
+ * FT_LOAD_FORCE_AUTOHINT ::
+ * Prefer the auto-hinter over the font's native hinter. See also
+ * the note below.
+ *
+ * FT_LOAD_PEDANTIC ::
+ * Make the font driver perform pedantic verifications during glyph
+ * loading. This is mostly used to detect broken glyphs in fonts.
+ * By default, FreeType tries to handle broken fonts also.
+ *
+ * In particular, errors from the TrueType bytecode engine are not
+ * passed to the application if this flag is not set; this might
+ * result in partially hinted or distorted glyphs in case a glyph's
+ * bytecode is buggy.
+ *
+ * FT_LOAD_NO_RECURSE ::
+ * Don't load composite glyphs recursively. Instead, the font
+ * driver should set the `num_subglyph' and `subglyphs' values of
+ * the glyph slot accordingly, and set `glyph->format' to
+ * @FT_GLYPH_FORMAT_COMPOSITE. The description of subglyphs can
+ * then be accessed with @FT_Get_SubGlyph_Info.
+ *
+ * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
+ *
+ * FT_LOAD_IGNORE_TRANSFORM ::
+ * Ignore the transform matrix set by @FT_Set_Transform.
+ *
+ * FT_LOAD_MONOCHROME ::
+ * This flag is used with @FT_LOAD_RENDER to indicate that you want to
+ * render an outline glyph to a 1-bit monochrome bitmap glyph, with
+ * 8~pixels packed into each byte of the bitmap data.
+ *
+ * Note that this has no effect on the hinting algorithm used. You
+ * should rather use @FT_LOAD_TARGET_MONO so that the
+ * monochrome-optimized hinting algorithm is used.
+ *
+ * FT_LOAD_LINEAR_DESIGN ::
+ * Keep `linearHoriAdvance' and `linearVertAdvance' fields of
+ * @FT_GlyphSlotRec in font units. See @FT_GlyphSlotRec for
+ * details.
+ *
+ * FT_LOAD_NO_AUTOHINT ::
+ * Disable the auto-hinter. See also the note below.
+ *
+ * FT_LOAD_COLOR ::
+ * [Since 2.5] Load embedded color bitmap images. The resulting color
+ * bitmaps, if available, will have the @FT_PIXEL_MODE_BGRA format.
+ * If the flag is not set and color bitmaps are found, they are
+ * converted to 256-level gray bitmaps transparently, using the
+ * @FT_PIXEL_MODE_GRAY format.
+ *
+ * FT_LOAD_COMPUTE_METRICS ::
+ * [Since 2.6.1] Compute glyph metrics from the glyph data, without
+ * the use of bundled metrics tables (for example, the `hdmx' table in
+ * TrueType fonts). This flag is mainly used by font validating or
+ * font editing applications, which need to ignore, verify, or edit
+ * those tables.
+ *
+ * Currently, this flag is only implemented for TrueType fonts.
+ *
+ * FT_LOAD_BITMAP_METRICS_ONLY ::
+ * [Since 2.7.1] Request loading of the metrics and bitmap image
+ * information of a (possibly embedded) bitmap glyph without
+ * allocating or copying the bitmap image data itself. No effect if
+ * the target glyph is not a bitmap image.
+ *
+ * This flag unsets @FT_LOAD_RENDER.
+ *
+ * FT_LOAD_CROP_BITMAP ::
+ * Ignored. Deprecated.
+ *
+ * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+ * Ignored. Deprecated.
+ *
+ * @note:
+ * By default, hinting is enabled and the font's native hinter (see
+ * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
+ * disable hinting by setting @FT_LOAD_NO_HINTING or change the
+ * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
+ * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
+ * used at all.
+ *
+ * See the description of @FT_FACE_FLAG_TRICKY for a special exception
+ * (affecting only a handful of Asian fonts).
+ *
+ * Besides deciding which hinter to use, you can also decide which
+ * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
+ *
+ * Note that the auto-hinter needs a valid Unicode cmap (either a native
+ * one or synthesized by FreeType) for producing correct results. If a
+ * font provides an incorrect mapping (for example, assigning the
+ * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
+ * mathematical integral sign), the auto-hinter might produce useless
+ * results.

+ *
+ * @enum:
+ * FT_LOAD_TARGET_XXX
+ *
+ * @description:
+ * A list of values to select a specific hinting algorithm for the
+ * hinter. You should OR one of these values to your `load_flags'
+ * when calling @FT_Load_Glyph.
+ *
+ * Note that a font's native hinters may ignore the hinting algorithm
+ * you have specified (e.g., the TrueType bytecode interpreter). You
+ * can set @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is
+ * used.
+ *
+ * @values:
+ * FT_LOAD_TARGET_NORMAL ::
+ * The default hinting algorithm, optimized for standard gray-level
+ * rendering. For monochrome output, use @FT_LOAD_TARGET_MONO
+ * instead.
+ *
+ * FT_LOAD_TARGET_LIGHT ::
+ * A lighter hinting algorithm for gray-level modes. Many generated
+ * glyphs are fuzzier but better resemble their original shape. This
+ * is achieved by snapping glyphs to the pixel grid only vertically
+ * (Y-axis), as is done by FreeType's new CFF engine or Microsoft's
+ * ClearType font renderer. This preserves inter-glyph spacing in
+ * horizontal text. The snapping is done either by the native font
+ * driver, if the driver itself and the font support it, or by the
+ * auto-hinter.
+ *
+ * Advance widths are rounded to integer values; however, using the
+ * `lsb_delta' and `rsb_delta' fields of @FT_GlyphSlotRec, it is
+ * possible to get fractional advance widths for sub-pixel positioning
+ * (which is recommended to use).
+ *
+ * If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active,
+ * TrueType-like metrics are used to make this mode behave similarly
+ * as in unpatched FreeType versions between 2.4.6 and 2.7.1
+ * (inclusive).
+ *
+ * FT_LOAD_TARGET_MONO ::
+ * Strong hinting algorithm that should only be used for monochrome
+ * output. The result is probably unpleasant if the glyph is rendered
+ * in non-monochrome modes.
+ *
+ * FT_LOAD_TARGET_LCD ::
+ * A variant of @FT_LOAD_TARGET_LIGHT optimized for horizontally
+ * decimated LCD displays.
+ *
+ * FT_LOAD_TARGET_LCD_V ::
+ * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
+ * decimated LCD displays.
+ *
+ * @note:
+ * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
+ * `load_flags'. They can't be ORed.
+ *
+ * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
+ * corresponding mode (i.e., the mode that matches the used algorithm
+ * best). An exception is FT_LOAD_TARGET_MONO since it implies
+ * @FT_LOAD_MONOCHROME.
+ *
+ * You can use a hinting algorithm that doesn't correspond to the same
+ * rendering mode. As an example, it is possible to use the `light'
+ * hinting algorithm and have the results rendered in horizontal LCD
+ * pixel mode, with code like
+ *
+ * {
+ * FT_Load_Glyph( face, glyph_index,
+ * load_flags | FT_LOAD_TARGET_LIGHT );
+ *
+ * FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );
+ * }
+ *
+ * In general, you should stick with one rendering mode. For example,
+ * switching between @FT_LOAD_TARGET_NORMAL and @FT_LOAD_TARGET_MONO
+ * enforces a lot of recomputation for TrueType fonts, which is slow.
+ * Another reason is caching: Selecting a different mode usually causes
+ * changes in both the outlines and the rasterized bitmaps; it is thus
+ * necessary to empty the cache after a mode switch to avoid false hits.

+ /* They are a sort of grey area somewhere between being totally */
+ /* irrelevant and semantically distinct; for this reason, the Unicode */
+ /* consortium decided to introduce Variation Sequences (VS), */
+ /* consisting of a Unicode base character and a variation selector */
+ /* instead of further extending the already huge number of */
+ /* characters. */
+ /* */
+ /* Unicode maintains two different sets, namely `Standardized */
+ /* Variation Sequences' and registered `Ideographic Variation */
+ /* Sequences' (IVS), collected in the `Ideographic Variation */

+ /* To date (January 2017), the character with the most ideographic */
+ /* variations is U+9089, having 32 such IVS. */
+ /* */
+ /* Three Mongolian Variation Selectors have the values U+180B-U+180D; */
+ /* 256 generic Variation Selectors are encoded in the ranges */
+ /* U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation */
+ /* Selectors from the range U+E0100-U+E01EF only. */

+ /* A VS consists of the base character value followed by a single */

+ *
+ * @description:
+ * While FreeType's CFF driver doesn't expose API functions by itself,
+ * it is possible to control its behaviour with @FT_Property_Set and
+ * @FT_Property_Get.
+ *
+ * The CFF driver's module name is `cff'.
+ *
+ * Available properties are @hinting-engine, @no-stem-darkening,
+ * @darkening-parameters, and @random-seed, as documented in the
+ * @properties section.
+ *
+ *
+ * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
+ *
+ * The rasterizer is positioning horizontal features (e.g., ascender
+ * height & x-height, or crossbars) on the pixel grid and minimizing the
+ * amount of antialiasing applied to them, while placing vertical
+ * features (vertical stems) on the pixel grid without hinting, thus
+ * representing the stem position and weight accurately. Sometimes the
+ * vertical stems may be only partially black. In this context,
+ * `antialiasing' means that stems are not positioned exactly on pixel
+ * borders, causing a fuzzy appearance.
+ *
+ * There are two principles behind this approach.
+ *
+ * 1) No hinting in the horizontal direction: Unlike `superhinted'
+ * TrueType, which changes glyph widths to accommodate regular
+ * inter-glyph spacing, Adobe's approach is `faithful to the design' in
+ * representing both the glyph width and the inter-glyph spacing
+ * designed for the font. This makes the screen display as close as it
+ * can be to the result one would get with infinite resolution, while
+ * preserving what is considered the key characteristics of each glyph.
+ * Note that the distances between unhinted and grid-fitted positions at
+ * small sizes are comparable to kerning values and thus would be
+ * noticeable (and distracting) while reading if hinting were applied.
+ *
+ * One of the reasons to not hint horizontally is antialiasing for LCD
+ * screens: The pixel geometry of modern displays supplies three
+ * vertical sub-pixels as the eye moves horizontally across each visible
+ * pixel. On devices where we can be certain this characteristic is
+ * present a rasterizer can take advantage of the sub-pixels to add
+ * increments of weight. In Western writing systems this turns out to
+ * be the more critical direction anyway; the weights and spacing of
+ * vertical stems (see above) are central to Armenian, Cyrillic, Greek,
+ * and Latin type designs. Even when the rasterizer uses greyscale
+ * antialiasing instead of color (a necessary compromise when one
+ * doesn't know the screen characteristics), the unhinted vertical
+ * features preserve the design's weight and spacing much better than
+ * aliased type would.
+ *
+ * 2) Alignment in the vertical direction: Weights and spacing along the
+ * y~axis are less critical; what is much more important is the visual
+ * alignment of related features (like cap-height and x-height). The
+ * sense of alignment for these is enhanced by the sharpness of grid-fit
+ * edges, while the cruder vertical resolution (full pixels instead of
+ * 1/3 pixels) is less of a problem.
+ *
+ * On the technical side, horizontal alignment zones for ascender,
+ * x-height, and other important height values (traditionally called
+ * `blue zones') as defined in the font are positioned independently,
+ * each being rounded to the nearest pixel edge, taking care of
+ * overshoot suppression at small sizes, stem darkening, and scaling.
+ *
+ * Hstems (this is, hint values defined in the font to help align
+ * horizontal features) that fall within a blue zone are said to be
+ * `captured' and are aligned to that zone. Uncaptured stems are moved
+ * in one of four ways, top edge up or down, bottom edge up or down.
+ * Unless there are conflicting hstems, the smallest movement is taken
+ * to minimize distortion.

+ *
+ * @abstract:
+ * Controlling the TrueType driver module.
+ *
+ * @description:
+ * While FreeType's TrueType driver doesn't expose API functions by
+ * itself, it is possible to control its behaviour with @FT_Property_Set
+ * and @FT_Property_Get. The following lists the available properties
+ * together with the necessary macros and structures.
+ *
+ * The TrueType driver's module name is `truetype'.
+ *
+ * A single property @interpreter-version is available, as documented in
+ * the @properties section.
+ *
+ * We start with a list of definitions, kindly provided by Greg
+ * Hitchcock.
+ *
+ * _Bi-Level_ _Rendering_
+ *
+ * Monochromatic rendering, exclusively used in the early days of
+ * TrueType by both Apple and Microsoft. Microsoft's GDI interface
+ * supported hinting of the right-side bearing point, such that the
+ * advance width could be non-linear. Most often this was done to
+ * achieve some level of glyph symmetry. To enable reasonable
+ * performance (e.g., not having to run hinting on all glyphs just to
+ * get the widths) there was a bit in the head table indicating if the
+ * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+ * cache hinting widths across multiple sizes and device aspect ratios.
+ *
+ * _Font_ _Smoothing_
+ *
+ * Microsoft's GDI implementation of anti-aliasing. Not traditional
+ * anti-aliasing as the outlines were hinted before the sampling. The
+ * widths matched the bi-level rendering.
+ *
+ * _ClearType_ _Rendering_
+ *
+ * Technique that uses physical subpixels to improve rendering on LCD
+ * (and other) displays. Because of the higher resolution, many methods
+ * of improving symmetry in glyphs through hinting the right-side
+ * bearing were no longer necessary. This lead to what GDI calls
+ * `natural widths' ClearType, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
+ * has extra resolution, most non-linearity went away, but it is still
+ * possible for hints to change the advance widths in this mode.
+ *
+ * _ClearType_ _Compatible_ _Widths_
+ *
+ * One of the earliest challenges with ClearType was allowing the
+ * implementation in GDI to be selected without requiring all UI and
+ * documents to reflow. To address this, a compatible method of
+ * rendering ClearType was added where the font hints are executed once
+ * to determine the width in bi-level rendering, and then re-run in
+ * ClearType, with the difference in widths being absorbed in the font
+ * hints for ClearType (mostly in the white space of hints); see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
+ * definition, compatible width ClearType allows for non-linear widths,
+ * but only when the bi-level version has non-linear widths.
+ *
+ * _ClearType_ _Subpixel_ _Positioning_
+ *
+ * One of the nice benefits of ClearType is the ability to more crisply
+ * display fractional widths; unfortunately, the GDI model of integer
+ * bitmaps did not support this. However, the WPF and Direct Write
+ * frameworks do support fractional widths. DWrite calls this `natural
+ * mode', not to be confused with GDI's `natural widths'. Subpixel
+ * positioning, in the current implementation of Direct Write,
+ * unfortunately does not support hinted advance widths, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
+ * TrueType interpreter fully allows the advance width to be adjusted in
+ * this mode, just the DWrite client will ignore those changes.
+ *
+ * _ClearType_ _Backward_ _Compatibility_
+ *
+ * This is a set of exceptions made in the TrueType interpreter to
+ * minimize hinting techniques that were problematic with the extra
+ * resolution of ClearType; see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+ * This technique is not to be confused with ClearType compatible
+ * widths. ClearType backward compatibility has no direct impact on
+ * changing advance widths, but there might be an indirect impact on
+ * disabling some deltas. This could be worked around in backward
+ * compatibility mode.
+ *
+ * _Native_ _ClearType_ _Mode_
+ *
+ * (Not to be confused with `natural widths'.) This mode removes all
+ * the exceptions in the TrueType interpreter when running with
+ * ClearType. Any issues on widths would still apply, though.

+ * Type~1, and CID font modules if the `Adobe' engine is selected (which
+ * is the default).
+ *
+ * Stem darkening emboldens glyphs at smaller sizes to make them more
+ * readable on common low-DPI screens when using linear alpha blending
+ * and gamma correction, see @FT_Render_Glyph. When not using linear
+ * alpha blending and gamma correction, glyphs will appear heavy and
+ * fuzzy!
+ *
+ * Gamma correction essentially lightens fonts since shades of grey are
+ * shifted to higher pixel values (=~higher brightness) to match the
+ * original intention to the reality of our screens. The side-effect is
+ * that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
+ * rendering library implement a counter-measure: stem darkening at
+ * smaller sizes where shades of gray dominate. By emboldening a glyph
+ * slightly in relation to its pixel size, individual pixels get higher
+ * coverage of filled-in outlines and are therefore `blacker'. This
+ * counteracts the `thinning out' of glyphs, making text remain readable
+ * at smaller sizes.
+ *
+ * By default, the Adobe engines for CFF, Type~1, and CID fonts darken

+ * thus switched off by default (this is, `no-stem-darkening' is set to
+ * TRUE by default). Total consistency with the CFF driver is not
+ * achieved right now because the emboldening method differs and glyphs
+ * must be scaled down on the Y-axis to keep outline points inside their
+ * precomputed blue zones. The smaller the size (especially 9ppem and

+ * TT_INTERPRETER_VERSION_40 ::
+ * Version~40 corresponds to MS rasterizer v.2.1; it is roughly
+ * equivalent to the hinting provided by DirectWrite ClearType (as can
+ * be found, for example, in Microsoft's Edge Browser on Windows~10).
+ * It is used in FreeType to select the `minimal' subpixel hinting
+ * code, a stripped-down and higher performance version of the
+ * `Infinality' code.
+ *
+ * @note:
+ * This property controls the behaviour of the bytecode interpreter
+ * and thus how outlines get hinted. It does *not* control how glyph
+ * get rasterized! In particular, it does not control subpixel color
+ * filtering.
+ *
+ * If FreeType has not been compiled with the configuration option
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+ * an `FT_Err_Unimplemented_Feature' error.
+ *
+ * Depending on the graphics framework, Microsoft uses different
+ * bytecode and rendering engines. As a consequence, the version
+ * numbers returned by a call to the `GETINFO' bytecode instruction are
+ * more convoluted than desired.
+ *
+ * Here are two tables that try to shed some light on the possible
+ * values for the MS rasterizer engine, together with the additional
+ * features introduced by it.
+ *
+ * {
+ * GETINFO framework version feature
+ * -------------------------------------------------------------------
+ * 3 GDI (Win 3.1), v1.0 16-bit, first version
+ * TrueImage
+ * 33 GDI (Win NT 3.1), v1.5 32-bit
+ * HP Laserjet
+ * 34 GDI (Win 95) v1.6 font smoothing,
+ * new SCANTYPE opcode
+ * 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
+ * bits in composite glyphs
+ * 36 MGDI (Win CE 2) v1.6+ classic ClearType
+ * 37 GDI (XP and later), v1.8 ClearType
+ * GDI+ old (before Vista)
+ * 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
+ * WPF Y-direction ClearType,
+ * additional error checking
+ * 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
+ * in GETINFO opcode,
+ * bug fixes
+ * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
+ * DWrite (Win 8) in GETINFO opcode,
+ * Gray ClearType
+ * }
+ *
+ * The `version' field gives a rough orientation only, since some
+ * applications provided certain features much earlier (as an example,
+ * Microsoft Reader used subpixel and Y-direction ClearType already in
+ * Windows 2000). Similarly, updates to a given framework might include
+ * improved hinting support.
+ *
+ * {
+ * version sampling rendering comment
+ * x y x y
+ * --------------------------------------------------------------
+ * v1.0 normal normal B/W B/W bi-level
+ * v1.6 high high gray gray grayscale
+ * v1.8 high normal color-filter B/W (GDI) ClearType
+ * v1.9 high high color-filter gray Color ClearType
+ * v2.1 high normal gray B/W Gray ClearType
+ * v2.1 high high gray gray Gray ClearType
+ * }
+ *
+ * Color and Gray ClearType are the two available variants of
+ * `Y-direction ClearType', meaning grayscale rasterization along the
+ * Y-direction; the name used in the TrueType specification for this
+ * feature is `symmetric smoothing'. `Classic ClearType' is the
+ * original algorithm used before introducing a modified version in
+ * Win~XP. Another name for v1.6's grayscale rendering is `font
+ * smoothing', and `Color ClearType' is sometimes also called `DWrite
+ * ClearType'. To differentiate between today's Color ClearType and the
+ * earlier ClearType variant with B/W rendering along the vertical axis,
+ * the latter is sometimes called `GDI ClearType'.
+ *
+ * `Normal' and `high' sampling describe the (virtual) resolution to
+ * access the rasterized outline after the hinting process. `Normal'
+ * means 1 sample per grid line (i.e., B/W). In the current Microsoft
+ * implementation, `high' means an extra virtual resolution of 16x16 (or
+ * 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
+ * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+ * lines for color filtering if Color ClearType is activated.
+ *
+ * Note that `Gray ClearType' is essentially the same as v1.6's
+ * grayscale rendering. However, the GETINFO instruction handles it
+ * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+ * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+ * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
+ * the version~1 gasp table exclusively (like Color ClearType), while
+ * v1.6 only respects the values of version~0 (bits 0 and~1).
+ *
+ * Keep in mind that the features of the above interpreter versions
+ * might not map exactly to FreeType features or behavior because it is
+ * a fundamentally different library with different internals.

+ *
+ * @property:
+ * interpreter-version
+ *
+ * @description:
+ * Currently, three versions are available, two representing the
+ * bytecode interpreter with subpixel hinting support (old `Infinality'
+ * code and new stripped-down and higher performance `minimal' code) and
+ * one without, respectively. The default is subpixel support if
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+ * otherwise (since it isn't available then).
+ *
+ * If subpixel hinting is on, many TrueType bytecode instructions behave
+ * differently compared to B/W or grayscale rendering (except if `native
+ * ClearType' is selected by the font). Microsoft's main idea is to
+ * render at a much increased horizontal resolution, then sampling down
+ * the created output to subpixel precision. However, many older fonts
+ * are not suited to this and must be specially taken care of by
+ * applying (hardcoded) tweaks in Microsoft's interpreter.
+ *
+ * Details on subpixel hinting and some of the necessary tweaks can be
+ * found in Greg Hitchcock's whitepaper at
+ * `https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
+ * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+ * or 6x5 supersampling) like discussed in the paper. Depending on the
+ * chosen interpreter, it simply ignores instructions on vertical stems
+ * to arrive at very similar results.
+ *
+ * The following example code demonstrates how to deactivate subpixel
+ * hinting (omitting the error handling).
+ *
+ * {
+ * FT_Library library;
+ * FT_Face face;

+ *
+ * @description:
+ * *Experimental* *only*
+ *
+ * The auto-hinter provides various script modules to hint glyphs.
+ * Examples of supported scripts are Latin or CJK. Before a glyph is
+ * auto-hinted, the Unicode character map of the font gets examined, and
+ * the script is then determined based on Unicode character ranges, see
+ * below.
+ *
+ * OpenType fonts, however, often provide much more glyphs than
+ * character codes (small caps, superscripts, ligatures, swashes, etc.),
+ * to be controlled by so-called `features'. Handling OpenType features
+ * can be quite complicated and thus needs a separate library on top of
+ * FreeType.
+ *
+ * The mapping between glyph indices and scripts (in the auto-hinter
+ * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
+ * array with `num_glyphs' elements, as found in the font's @FT_Face
+ * structure. The `glyph-to-script-map' property returns a pointer to
+ * this array, which can be modified as needed. Note that the
+ * modification should happen before the first glyph gets processed by
+ * the auto-hinter so that the global analysis of the font shapes
+ * actually uses the modified mapping.

+ *
+ * @title:
+ * LCD Filtering
+ *
+ * @abstract:
+ * Reduce color fringes of subpixel-rendered bitmaps.
+ *
+ * @description:
+ * Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
+ * `ftoption.h', which enables patented ClearType-style rendering,
+ * the LCD-optimized glyph bitmaps should be filtered to reduce color
+ * fringes inherent to this technology. The default FreeType LCD
+ * rendering uses different technology, and API described below,
+ * although available, does nothing.
+ *
+ * ClearType-style LCD rendering exploits the color-striped structure of
+ * LCD pixels, increasing the available resolution in the direction of
+ * the stripe (usually horizontal RGB) by a factor of~3. Since these
+ * subpixels are color pixels, using them unfiltered creates severe
+ * color fringes. Use the @FT_Library_SetLcdFilter API to specify a
+ * low-pass filter, which is then applied to subpixel-rendered bitmaps
+ * generated through @FT_Render_Glyph. The filter sacrifices some of
+ * the higher resolution to reduce color fringes, making the glyph image
+ * slightly blurrier. Positional improvements will remain.
+ *
+ * A filter should have two properties:
+ *
+ * 1) It should be normalized, meaning the sum of the 5~components
+ * should be 256 (0x100). It is possible to go above or under this
+ * target sum, however: going under means tossing out contrast, going
+ * over means invoking clamping and thereby non-linearities that
+ * increase contrast somewhat at the expense of greater distortion
+ * and color-fringing. Contrast is better enhanced through stem
+ * darkening.
+ *
+ * 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
+ * where a~+ b~=~c. It distributes the computed coverage for one
+ * subpixel to all subpixels equally, sacrificing some won resolution
+ * but drastically reducing color-fringing. Positioning improvements
+ * remain! Note that color-fringing can only really be minimized
+ * when using a color-balanced filter and alpha-blending the glyph
+ * onto a surface in linear space; see @FT_Render_Glyph.
+ *
+ * Regarding the form, a filter can be a `boxy' filter or a `beveled'
+ * filter. Boxy filters are sharper but are less forgiving of non-ideal
+ * gamma curves of a screen (viewing angles!), beveled filters are
+ * fuzzier but more tolerant.
+ *
+ * Examples:
+ *
+ * - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
+ * normalized.
+ *
+ * - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
+ * normalized.
+ *
+ * - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
+ * balanced.
+ *
+ * - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
+ * balanced.
+ *
+ * - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
+ * balanced.
+ *
+ * - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
+ * balanced.
+ *
+ * The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
+ * @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
+ * of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
+ *
+ * If this feature is activated, the dimensions of LCD glyph bitmaps are
+ * either wider or taller than the dimensions of the corresponding
+ * outline with regard to the pixel grid. For example, for
+ * @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
+ * 3~subpixels to the right. The bitmap offset values are adjusted
+ * accordingly, so clients shouldn't need to modify their layout and
+ * glyph positioning code when enabling the filter.
+ *
+ * It is important to understand that linear alpha blending and gamma
+ * correction is critical for correctly rendering glyphs onto surfaces
+ * without artifacts and even more critical when subpixel rendering is
+ * involved.
+ *
+ * Each of the 3~alpha values (subpixels) is independently used to blend
+ * one color channel. That is, red alpha blends the red channel of the
+ * text color with the red channel of the background pixel. The
+ * distribution of density values by the color-balanced filter assumes
+ * alpha blending is done in linear space; only then color artifacts
+ * cancel out.

+ * @enum:
+ * FT_LcdFilter
+ *
+ * @description:
+ * A list of values to identify various types of LCD filters.
+ *
+ * @values:
+ * FT_LCD_FILTER_NONE ::
+ * Do not perform filtering. When used with subpixel rendering, this
+ * results in sometimes severe color fringes.
+ *
+ * FT_LCD_FILTER_DEFAULT ::
+ * The default filter reduces color fringes considerably, at the cost
+ * of a slight blurriness in the output.
+ *
+ * It is a beveled, normalized, and color-balanced five-tap filter
+ * that is more forgiving to screens with non-ideal gamma curves and
+ * viewing angles. Note that while color-fringing is reduced, it can
+ * only be minimized by using linear alpha blending and gamma
+ * correction to render glyphs onto surfaces. The default filter
+ * weights are [0x08 0x4D 0x56 0x4D 0x08].
+ *
+ * FT_LCD_FILTER_LIGHT ::
+ * The light filter is a variant that is sharper at the cost of
+ * slightly more color fringes than the default one.
+ *
+ * It is a boxy, normalized, and color-balanced three-tap filter that
+ * is less forgiving to screens with non-ideal gamma curves and
+ * viewing angles. This filter works best when the rendering system
+ * uses linear alpha blending and gamma correction to render glyphs
+ * onto surfaces. The light filter weights are
+ * [0x00 0x55 0x56 0x55 0x00].
+ *
+ * FT_LCD_FILTER_LEGACY ::
+ * This filter corresponds to the original libXft color filter. It
+ * provides high contrast output but can exhibit really bad color
+ * fringes if glyphs are not extremely well hinted to the pixel grid.
+ * In other words, it only works well if the TrueType bytecode
+ * interpreter is enabled *and* high-quality hinted fonts are used.
+ *
+ * This filter is only provided for comparison purposes, and might be
+ * disabled or stay unsupported in the future.
+ *
+ * FT_LCD_FILTER_LEGACY1 ::
+ * For historical reasons, the FontConfig library returns a different
+ * enumeration value for legacy LCD filtering. To make code work that
+ * (incorrectly) forwards FontConfig's enumeration value to
+ * @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
+ * to have another enumeration value, which is completely equal to
+ * `FT_LCD_FILTER_LEGACY'.

+ * the joined lines is filled by enclosing the triangular
+ * region of the corner with a straight line between the
+ * outer corners of each stroke.
+ *
+ * FT_STROKER_LINEJOIN_MITER_FIXED ::
+ * Used to render mitered line joins, with fixed bevels if the
+ * miter limit is exceeded. The outer edges of the strokes
+ * for the two segments are extended until they meet at an
+ * angle. If the segments meet at too sharp an angle (such
+ * that the miter would extend from the intersection of the
+ * segments a distance greater than the product of the miter
+ * limit value and the border radius), then a bevel join (see
+ * above) is used instead. This prevents long spikes being
+ * created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter
+ * line join as used in PostScript and PDF.
+ *
+ * FT_STROKER_LINEJOIN_MITER_VARIABLE ::
+ * FT_STROKER_LINEJOIN_MITER ::
+ * Used to render mitered line joins, with variable bevels if
+ * the miter limit is exceeded. The intersection of the
+ * strokes is clipped at a line perpendicular to the bisector
+ * of the angle between the strokes, at the distance from the
+ * intersection of the segments equal to the product of the
+ * miter limit value and the border radius. This prevents
+ * long spikes being created.
+ * FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line
+ * join as used in XPS. FT_STROKER_LINEJOIN_MITER is an alias
+ * for FT_STROKER_LINEJOIN_MITER_VARIABLE, retained for

+ /* An automatic hinter might compute two kinds of data for a given face: */
+ /* */
+ /* - global hints: Usually some metrics that describe global properties */
+ /* of the face. It is computed by scanning more or less */
+ /* aggressively the glyphs in the face, and thus can be */
+ /* very slow to compute (even if the size of global */
+ /* hints is really small). */
+ /* */
+ /* - glyph hints: These describe some important features of the glyph */
+ /* outline, as well as how to align them. They are */
+ /* generally much faster to compute than global hints. */
+ /* */
+ /* The current FreeType auto-hinter does a pretty good job while */
+ /* performing fast computations for both global and glyph hints. */
+ /* However, we might be interested in introducing more complex and */
+ /* powerful algorithms in the future, like the one described in the John */
+ /* D. Hobby paper, which unfortunately requires a lot more horsepower. */
+ /* */
+ /* Because a sufficiently sophisticated font management system would */
+ /* typically implement an LRU cache of opened face objects to reduce */
+ /* memory usage, it is a good idea to be able to avoid recomputing */
+ /* global hints every time the same face is re-opened. */
+ /* */
+ /* We thus provide the ability to cache global hints outside of the face */
+ /* object, in order to speed up font re-opening time. Of course, this */
+ /* feature is purely optional, so most client programs won't even notice */
+ /* it. */
+ /* */
+ /* I initially thought that it would be a good idea to cache the glyph */
+ /* hints too. However, my general idea now is that if you really need */
+ /* to cache these too, you are simply in need of a new font format, */

+
+
+// This file contains data specific to blue zones. It gets processed by
+// a script to simulate `jagged arrays', with enumeration values holding
+// offsets into the arrays.
+//
+// The format of the file is rather simple: A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template. The script then fills the corresponding templates
+// (indicated by `@' characters around the name).
+//
+// A section contains one or more data records. Each data record consists
+// of two or more lines. The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters or character clusters (for example, representing
+// Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
+// quotes, using C syntax, where the elements are separated by spaces.
+// There can be only one string per line, thus the starting and ending
+// double quote must be the first and last character in the line,
+// respectively, ignoring whitespace before and after the string. If
+// there are multiple strings (in multiple lines), they are concatenated
+// to a single string. In the output, a string gets represented as a
+// series of singles bytes, followed by a zero byte. The enumeration
+// values simply hold byte offsets to the start of the corresponding
+// strings.
+//
+// For strings, the `maximum' template holds the maximum number of
+// non-space characters in all strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+// which can span multiple lines. The opening brace of a block must be
+// the first character of a line (ignoring whitespace), and the closing
+// brace the last (ignoring whitespace also). The script appends a comma
+// character after each block and counts the number of blocks to set the
+// enumeration values.
+//
+// For data blocks, the `maximum' template holds the maximum number of
+// array elements.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed. A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array. Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum
+// values; this essentially means that the maximum values can easily be too
+// large. Given that the purpose of those values is to create local
+// fixed-size arrays at compile time for further processing of the blue zone
+// data, this isn't a problem. Note the final zero byte of a string is not
+// counted. Note also that the count holds the number of UTF-8 encoded
+// characters, not bytes.

+// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
+//
+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored). All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum. The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively. Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// Some scripts like Khmer need character composition to get all necessary
+// blue zones, since Unicode only provides an abstract data model that
+// doesn't represent all possible glyph shapes. For such character
+// clusters, the HarfBuzz library is used to convert them into the
+// corresponding glyphs. The largest glyph element (where `largest' can be
+// either `largest ascender' or `largest descender') then defines the
+// corresponding flat or round extremum.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// LATIN_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters for computing the blue zone's reference and overshoot
+// values.
+//
+// If not set, take the minimum values.
+//
+// Mutually exclusive with `LATIN_SUB_TOP'.
+//
+// LATIN_SUB_TOP
+// For all glyphs of a character cluster, compute the maximum flat
+// and round coordinate values of each component, then take the
+// smallest of the maximum values. The idea is to get the top of
+// subscript glyphs, as used in Khmer, for example. Note that
+// this mechanism doesn't work for ordinary ligatures.
+//
+// This flags indicates a secondary blue zone: It gets removed if
+// there is a non-LATIN_SUB_TOP blue zone at the same coordinate
+// value (after scaling).
+//
+// Mutually exclusive with `LATIN_TOP'.
+//
+// LATIN_NEUTRAL
+// Ignore round extrema and define the blue zone with flat values only.
+// Both top and bottom of contours can match. This is useful for
+// scripts like Devanagari where vowel signs attach to the base
+// character and are implemented as components of composite glyphs.
+//
+// If not set, both round and flat extrema are taken into account.
+// Additionally, only the top or the bottom of a contour can match,
+// depending on the LATIN_TOP flag.
+//
+// Neutral blue zones should always follow non-neutral blue zones.
+//
+// LATIN_X_HEIGHT
+// Scale all glyphs vertically from the corresponding script to make the
+// reference line of this blue zone align on the grid. The scaling
+// takes place before all other blue zones get aligned to the grid.
+// Only one blue character string of a script style can have this flag.
+//
+// LATIN_LONG
+// Apply an additional constraint for blue zone values: Don't
+// necessarily use the extremum as-is but a segment of the topmost (or
+// bottommost) contour that is longer than a heuristic threshold, and
+// which is not too far away vertically from the real extremum. This
+// ensures that small bumps in the outline are ignored (for example, the
+// `vertical serifs' found in many Hebrew glyph designs).
+//
+// The segment must be at least EM/25 font units long, and the distance
+// to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified. Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value
+// (everything separated by space characters). The blue zone is then set up
+// by the mean values of all reference values and all overshoot values,
+// respectively. Both horizontal and vertical blue zones (i.e., adjusting
+// vertical and horizontal coordinate values, respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// CJK_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters. If not set, take the minimum values.
+//
+// CJK_RIGHT
+// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the
+// right blue zone, taking horizontal maximum values.
+//
+// CJK_HORIZ
+// Define a blue zone for horizontal hinting (i.e., vertical blue
+// zones). If not set, this is a blue zone for vertical hinting.

+ * The following explanations are mostly taken from the article

+ *
+ *
+ * Segments
+ *
+ * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
+ * find segments in an outline.
+ *
+ * A segment is a series of at least two consecutive points that are
+ * approximately aligned along a coordinate axis. The analysis to do
+ * so is specific to a writing system.
+ *
+ *
+ * Edges
+ *
+ * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
+ * edges.
+ *
+ * As soon as segments are defined, the auto-hinter groups them into
+ * edges. An edge corresponds to a single position on the main
+ * dimension that collects one or more segments (allowing for a small
+ * threshold).
+ *
+ * As an example, the `latin' writing system first tries to grid-fit
+ * edges, then to align segments on the edges unless it detects that
+ * they form a serif.

+ *
+ *
+ * Stems
+ *
+ * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * Segments need to be `linked' to other ones in order to detect stems.
+ * A stem is made of two segments that face each other in opposite
+ * directions and that are sufficiently close to each other. Using
+ * vocabulary from the TrueType specification, stem segments form a
+ * `black distance'.
+ *
+ * In the above ASCII drawing, the horizontal segments are BC, DE, and
+ * FG; the vertical segments are AB, CD, EF, and GH.
+ *
+ * Each segment has at most one `best' candidate to form a black
+ * distance, or no candidate at all. Notice that two distinct segments
+ * can have the same candidate, which frequently means a serif.
+ *
+ * A stem is recognized by the following condition:
+ *
+ * best segment_1 = segment_2 && best segment_2 = segment_1
+ *
+ * The best candidate is stored in field `link' in structure
+ * `AF_Segment'.
+ *
+ * In the above ASCII drawing, the best candidate for both AB and CD is
+ * GH, while the best candidate for GH is AB. Similarly, the best
+ * candidate for EF and GH is AB, while the best candidate for AB is
+ * GH.
+ *
+ * The detection and handling of stems is dependent on the writing
+ * system.
+ *
+ *
+ * Serifs
+ *
+ * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * In comparison to a stem, a serif (as handled by the auto-hinter
+ * module that takes care of the `latin' writing system) has
+ *
+ * best segment_1 = segment_2 && best segment_2 != segment_1
+ *
+ * where segment_1 corresponds to the serif segment (CD and EF in the
+ * above ASCII drawing).
+ *
+ * The best candidate is stored in field `serif' in structure
+ * `AF_Segment' (and `link' is set to NULL).
+ *
+ *
+ * Touched points
+ *
+ * A point is called `touched' if it has been processed somehow by the
+ * auto-hinter. It basically means that it shouldn't be moved again
+ * (or moved only under certain constraints to preserve the already
+ * applied processing).
+ *
+ *
+ * Flat and round segments
+ *
+ * Segments are `round' or `flat', depending on the series of points
+ * that define them. A segment is round if the next and previous point
+ * of an extremum (which can be either a single point or sequence of
+ * points) are both conic or cubic control points. Otherwise, a
+ * segment with an extremum is flat.
+ *
+ *
+ * Strong Points
+ *
+ * Experience has shown that points not part of an edge need to be
+ * interpolated linearly between their two closest edges, even if these
+ * are not part of the contour of those particular points. Typical
+ * candidates for this are
+ *
+ * - angle points (i.e., points where the `in' and `out' direction
+ * differ greatly)
+ *
+ * - inflection points (i.e., where the `in' and `out' angles are the
+ * same, but the curvature changes sign) [currently, such points
+ * aren't handled specially in the auto-hinter]
+ *
+ * `af_glyph_hints_align_strong_points' is the function that takes
+ * care of such situations; it is equivalent to the TrueType `IP'
+ * hinting instruction.
+ *
+ *
+ * Weak Points
+ *
+ * Other points in the outline must be interpolated using the
+ * coordinates of their previous and next unfitted contour neighbours.
+ * These are called `weak points' and are touched by the function
+ * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
+ * hinting instruction. Typical candidates are control points and
+ * points on the contour without a major direction.
+ *
+ * The major effect is to reduce possible distortion caused by
+ * alignment of edges and strong points, thus weak points are processed
+ * after strong points.

+ * could be the same. However, the auto-hinter is completely
+ * agnostic of OpenType features after the feature analysis has been
+ * completed: The engine then simply receives a glyph index and returns a
+ * hinted and usually rendered glyph.
+ *
+ * Consider the superscript feature of font `pala.ttf': Some of the
+ * glyphs are `real', this is, they have a zero vertical offset, but
+ * most of them are small caps glyphs shifted up to the superscript
+ * position (this is, the `sups' feature is present in both the GSUB and
+ * GPOS tables). The code for blue zones computation actually uses a
+ * feature's y offset so that the `real' glyphs get correct hints. But
+ * later on it is impossible to decide whether a glyph index belongs to,
+ * say, the small caps or superscript feature.
+ *
+ * For this reason, we don't assign a style to a glyph if the current
+ * feature covers the glyph in both the GSUB and the GPOS tables. This
+ * is quite a broad condition, assuming that
+ *
+ * (a) glyphs that get used in multiple features are present in a
+ * feature without vertical shift,
+ *
+ * and
+ *
+ * (b) a feature's GPOS data really moves the glyph vertically.
+ *
+ * Not fulfilling condition (a) makes a font larger; it would also
+ * reduce the number of glyphs that could be addressed directly without
+ * using OpenType features, so this assumption is rather strong.
+ *
+ * Condition (b) is much weaker, and there might be glyphs which get
+ * missed. However, the OpenType features we are going to handle are
+ * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+ * directly get the necessary information from the GPOS table. A
+ * possible solution might be to directly parse the GPOS table to find
+ * out whether a glyph gets shifted vertically, but this is something I
+ * would like to avoid if not really necessary.
+ *
+ * Note that we don't follow this logic for the default coverage.
+ * Complex scripts like Devanagari have mandatory GPOS features to
+ * position many glyph elements, using mark-to-base or mark-to-ligature
+ * tables; the number of glyphs missed due to condition (b) would be far
+ * too large.

+ * Usually, a font contains more glyphs than can be addressed by its
+ * character map.
+ *
+ * In the PostScript font world, encoding vectors specific to a given
+ * task are used to select such glyphs, and these glyphs can be often
+ * recognized by having a suffix in its glyph names. For example, a
+ * superscript glyph `A' might be called `A.sup'. Unfortunately, this
+ * naming scheme is not standardized and thus unusable for us.
+ *
+ * In the OpenType world, a better solution was invented, namely
+ * `features', which cleanly separate a character's input encoding from
+ * the corresponding glyph's appearance, and which don't use glyph names
+ * at all. For our purposes, and slightly generalized, an OpenType
+ * feature is a name of a mapping that maps character codes to
+ * non-standard glyph indices (features get used for other things also).
+ * For example, the `sups' feature provides superscript glyphs, thus
+ * mapping character codes like `A' or `B' to superscript glyph
+ * representation forms. How this mapping happens is completely
+ * uninteresting to us.
+ *
+ * For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+ * feature collected in a set (as listed below) that can be hinted
+ * together. To continue the above example, superscript glyphs must not
+ * be hinted together with normal glyphs because the blue zones
+ * completely differ.
+ *
+ * Note that FreeType itself doesn't compute coverages; it only provides
+ * the glyphs addressable by the default Unicode character map. Instead,
+ * we use the HarfBuzz library (if available), which has many functions
+ * exactly for this purpose.
+ *
+ * AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+ * listed separately (including the glyphs addressable by the character
+ * map). In case HarfBuzz isn't available, it exactly covers the glyphs
+ * addressable by the character map.

+ Notes
+
+ Mac suitcase files can (and often do!) contain multiple fonts. To
+ support this I use the face_index argument of FT_(Open|New)_Face()
+ functions, and pretend the suitcase file is a collection.
+
+ Warning: fbit and NFNT bitmap resources are not supported yet. In old
+ sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+ resources instead of the `bdat' table in the sfnt resource. Therefore,
+ face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+ resource is unavailable at present.
+
+ The Mac FOND support works roughly like this:
+
+ - Check whether the offered stream points to a Mac suitcase file. This
+ is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
+ stream that gets passed to our init_face() routine is a stdio stream,
+ which isn't usable for us, since the FOND resources live in the
+ resource fork. So we just grab the stream->pathname field.
+
+ - Read the FOND resource into memory, then check whether there is a
+ TrueType font and/or(!) a Type 1 font available.
+
+ - If there is a Type 1 font available (as a separate `LWFN' file), read
+ its data into memory, massage it slightly so it becomes PFB data, wrap
+ it into a memory stream, load the Type 1 driver and delegate the rest
+ of the work to it by calling FT_Open_Face(). (XXX TODO: after this
+ has been done, the kerning data from the FOND resource should be
+ appended to the face: On the Mac there are usually no AFM files
+ available. However, this is tricky since we need to map Mac char
+ codes to ps glyph names to glyph ID's...)
+
+ - If there is a TrueType font (an `sfnt' resource), read it into memory,
+ wrap it into a memory stream, load the TrueType driver and delegate
+ the rest of the work to it, by calling FT_Open_Face().
+
+ - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+ itself, even though it doesn't contains `POST' resources. To handle
+ this special case without opening the file an extra time, we just
+ ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+ available.

+ * A poor-man error facility.

+ * This code being written in vanilla C, doesn't have the luxury of a
+ * language-supported exception mechanism such as the one available in
+ * Java. Instead, we are stuck with using error codes that must be
+ * carefully managed and preserved. However, it is convenient for us to
+ * model our error mechanism on a Java-like exception mechanism.
+ * When we assign an error code we are thus `throwing' an error.
+ *
+ * The preservation of an error code is done by coding convention.
+ * Upon a function call if the error code is anything other than
+ * `FT_Err_Ok', which is guaranteed to be zero, we
+ * will return without altering that error. This will allow the
+ * error to propagate and be handled at the appropriate location in
+ * the code.
+ *
+ * This allows a style of code where the error code is initialized
+ * up front and a block of calls are made with the error code only
+ * being checked after the block. If a new error occurs, the original
+ * error will be preserved and a functional no-op should result in any
+ * subsequent function that has an initial error code not equal to
+ * `FT_Err_Ok'.
+ *
+ * Errors are encoded by calling the `FT_THROW' macro. For example,
+ *
+ * {
+ * FT_Error e;
+ *
+ *
+ * ...
+ * e = FT_THROW( Out_Of_Memory );

+ /* */
+ /* o its scanline position boundaries, i.e. `Ymin' and `Ymax' */

+ /* between `Ymin' and `Ymax' */
+ /* */
+ /* o a direction, indicating whether it was built going `up' or */
+ /* `down', as this is very important for filling rules */
+ /* */
+ /* o its drop-out mode */
+ /* */
+ /* 2 - Sweeping the target map's scanlines in order to compute segment */
+ /* `spans' which are then filled. Additionally, this pass */
+ /* performs drop-out control. */
+ /* */
+ /* The outline data is parsed during step 1 only. The profiles are */
+ /* built from the bottom of the render pool, used as a stack. The */
+ /* following graphics shows the profile list under construction: */
+ /* */
+ /* __________________________________________________________ _ _ */
+ /* | | | | | */
+ /* | profile | coordinates for | profile | coordinates for |--> */
+ /* | 1 | profile 1 | 2 | profile 2 |--> */
+ /* |_________|_________________|_________|_________________|__ _ _ */
+ /* */
+ /* ^ ^ */
+ /* | | */
+ /* start of render pool top */
+ /* */
+ /* The top of the profile stack is kept in the `top' variable. */
+ /* */
+ /* As you can see, a profile record is pushed on top of the render */
+ /* pool, which is then followed by its coordinates/intersections. If */
+ /* a change of direction is detected in the outline, a new profile is */
+ /* generated until the end of the outline. */
+ /* */
+ /* Note that when all profiles have been generated, the function */
+ /* Finalize_Profile_Table() is used to record, for each profile, its */
+ /* bottom-most scanline as well as the scanline above its upmost */
+ /* boundary. These positions are called `y-turns' because they (sort */
+ /* of) correspond to local extrema. They are stored in a sorted list */
+ /* built from the top of the render pool as a downwards stack: */
+ /* */
+ /* _ _ _______________________________________ */
+ /* | | */
+ /* <--| sorted list of | */
+ /* <--| extrema scanlines | */
+ /* _ _ __________________|____________________| */
+ /* */
+ /* ^ ^ */
+ /* | | */
+ /* maxBuff sizeBuff = end of pool */
+ /* */
+ /* This list is later used during the sweep phase in order to */
+ /* optimize performance (see technical note on the sweep below). */

+ /***** *****/
+ /***** The purpose of this format is to easily map UTF-16 text to *****/
+ /***** glyph indices. Basically, the `char_code' must be in one of *****/
+ /***** the following formats. *****/
+ /***** *****/
+ /***** - A 16-bit value that isn't part of the Unicode Surrogates *****/
+ /***** Area (i.e. U+D800-U+DFFF). *****/
+ /***** *****/
+ /***** - A 32-bit value, made of two surrogate values, i.e.. if *****/
+ /***** `char_code = (char_hi << 16) | char_lo', then both *****/
+ /***** `char_hi' and `char_lo' must be in the Surrogates Area. *****/
+ /***** Area. *****/
+ /***** *****/
+ /***** The `is32' table embedded in the charmap indicates whether a *****/
+ /***** given 16-bit value is in the surrogates area or not. *****/
+ /***** *****/
+ /***** So, for any given `char_code', we can assert the following. *****/
+ /***** *****/
+ /***** If `char_hi == 0' then we must have `is32[char_lo] == 0'. *****/
+ /***** *****/
+ /***** If `char_hi != 0' then we must have both *****/
+ /***** `is32[char_hi] != 0' and `is32[char_lo] != 0'. *****/

+ * Calculate the phantom points
+ *
+ * Defining the right side bearing (rsb) as
+ *
+ * rsb = aw - (lsb + xmax - xmin)
+ *
+ * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
+ * and `xmax' the glyph's minimum and maximum x value), the OpenType
+ * specification defines the initial position of horizontal phantom points
+ * as
+ *
+ * pp1 = (round(xmin - lsb), 0) ,
+ * pp2 = (round(pp1 + aw), 0) .
+ *
+ * Note that the rounding to the grid (in the device space) is not
+ * documented currently in the specification.
+ *
+ * However, the specification lacks the precise definition of vertical
+ * phantom points. Greg Hitchcock provided the following explanation.
+ *
+ * - a `vmtx' table is present
+ *
+ * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
+ * are given in the `glyf' table, the top side bearing (tsb) and advance
+ * height (ah) are given in the `vmtx' table. The bottom side bearing
+ * (bsb) is then calculated as
+ *
+ * bsb = ah - (tsb + ymax - ymin) ,
+ *
+ * and the initial position of vertical phantom points is
+ *
+ * pp3 = (x, round(ymax + tsb)) ,
+ * pp4 = (x, round(pp3 - ah)) .
+ *
+ * See below for value `x'.
+ *
+ * - no `vmtx' table in the font
+ *
+ * If there is an `OS/2' table, we set
+ *
+ * DefaultAscender = sTypoAscender ,
+ * DefaultDescender = sTypoDescender ,
+ *
+ * otherwise we use data from the `hhea' table:
+ *
+ * DefaultAscender = Ascender ,
+ * DefaultDescender = Descender .
+ *
+ * With these two variables we can now set
+ *
+ * ah = DefaultAscender - sDefaultDescender ,
+ * tsb = DefaultAscender - yMax ,
+ *
+ * and proceed as if a `vmtx' table was present.
+ *
+ * Usually we have
+ *
+ * x = aw / 2 , (1)
+ *
+ * but there is one compatibility case where it can be set to
+ *
+ * x = -DefaultDescender -
+ * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
+ *
+ * and another one with
+ *
+ * x = 0 . (3)
+ *
+ * In Windows, the history of those values is quite complicated,
+ * depending on the hinting engine (that is, the graphics framework).

+ /*
+ * FreeType supports ClearType-like hinting of TrueType fonts through
+ * the version 40 interpreter. This is achieved through several hacks
+ * in the base (v35) interpreter, as detailed below.
+ *
+ * ClearType is an umbrella term for several rendering techniques
+ * employed by Microsoft's various GUI and rendering toolkit
+ * implementations, most importantly: subpixel rendering for using the
+ * RGB subpixels of LCDs to approximately triple the perceived
+ * resolution on the x-axis and subpixel hinting for positioning stems
+ * on subpixel borders. TrueType programming is explicit, i.e., fonts
+ * must be programmed to take advantage of ClearType's possibilities.
+ *
+ * When ClearType was introduced, it seemed unlikely that all fonts
+ * would be reprogrammed, so Microsoft decided to implement a backward
+ * compatibility mode. It employs several simple to complicated
+ * assumptions and tricks, many of them font-dependent, that modify the
+ * interpretation of the bytecode contained in these fonts to retrofit
+ * them into a ClearType-y look. The quality of the results varies.
+ * Most (web)fonts that were released since then have come to rely on
+ * these hacks to render correctly, even some of Microsoft's flagship
+ * fonts (e.g., Calibri, Cambria, Segoe UI).
+ *
+ * FreeType's minimal subpixel hinting code (interpreter version 40)
+ * employs a small list of font-agnostic hacks loosely based on the
+ * public information available on Microsoft's compatibility mode[2].
+ * The focus is on modern (web)fonts rather than legacy fonts that were
+ * made for monochrome rendering. It will not match ClearType rendering
+ * exactly. Unlike the `Infinality' code (interpreter version 38) that
+ * came before, it will not try to toggle hacks for specific fonts for
+ * performance and complexity reasons. It will fall back to version 35
+ * behavior for tricky fonts[1] or when monochrome rendering is
+ * requested.
+ *
+ * Major hacks
+ *
+ * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+ * `Direct_Move_X'). This has the smallest code footprint and single
+ * biggest effect. The ClearType way to increase resolution is
+ * supersampling the x axis, the FreeType way is ignoring instructions
+ * on the x axis, which gives the same result in the majority of
+ * cases.
+ *
+ * - Points are not moved post-IUP (neither on the x nor on the y axis),
+ * except the x component of diagonal moves post-IUP (cf.
+ * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
+ * changes are commonly used to `fix' pixel patterns which has little
+ * use outside monochrome rendering.
+ *
+ * - SHPIX and DELTAP don't execute unless moving a composite on the
+ * y axis or moving a previously y touched point. SHPIX additionally
+ * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+ * Both instructions are commonly used to `fix' pixel patterns for
+ * monochrome or Windows's GDI rendering but make little sense for
+ * FreeType rendering. Both can distort the outline. See [2] for
+ * details.
+ *
+ * - The hdmx table and modifications to phantom points are ignored.
+ * Bearings and advance widths remain unchanged (except rounding them
+ * outside the interpreter!), cf. `compute_glyph_metrics' and
+ * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
+ * might mess up spacing.
+ *
+ * Minor hacks
+ *
+ * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
+ * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+ * various sizes.
+ *
+ * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+ * executed.)
+ *
+ * The best results are achieved for fonts that were from the outset
+ * designed with ClearType in mind, meaning they leave the x axis mostly
+ * alone and don't mess with the `final' outline to produce more
+ * pleasing pixel patterns. The harder the designer tried to produce
+ * very specific patterns (`superhinting') for pre-ClearType-displays,
+ * the worse the results.
+ *
+ * Microsoft defines a way to turn off backward compatibility and
+ * interpret instructions as before (called `native ClearType')[2][3].
+ * The font designer then regains full control and is responsible for
+ * making the font work correctly with ClearType without any
+ * hand-holding by the interpreter or rasterizer[4]. The v40
+ * interpreter assumes backward compatibility by default, which can be
+ * turned off the same way by executing the following in the control
+ * program (cf. `Ins_INSTCTRL').
+ *
+ * #PUSH 4,3
+ * INSTCTRL[]
+ *
+ * [1] Tricky fonts as FreeType defines them rely on the bytecode
+ * interpreter to display correctly. Hacks can interfere with them,
+ * so they get treated like native ClearType fonts (v40 with
+ * backward compatibility turned off). Cf. `TT_RunIns'.
+ *
+ * [2] Proposed by Microsoft's Greg Hitchcock in
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+ *
+ * [3] Beat Stamm describes it in more detail:
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
+ *
+ * [4] The list of `native ClearType' fonts is small at the time of this
+ * writing; I found the following on a Windows 10 Update 1511
+ * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+ * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+ * SimSun, NSimSun, and Yu Gothic.

+ /* A note regarding non-squared pixels: */
+ /* */
+ /* (This text will probably go into some docs at some time; for now, it */
+ /* is kept here to explain some definitions in the TT_Size_Metrics */
+ /* record). */
+ /* */
+ /* The CVT is a one-dimensional array containing values that control */
+ /* certain important characteristics in a font, like the height of all */
+ /* capitals, all lowercase letter, default spacing or stem width/height. */
+ /* */
+ /* These values are found in FUnits in the font file, and must be scaled */
+ /* to pixel coordinates before being used by the CVT and glyph programs. */
+ /* Unfortunately, when using distinct x and y resolutions (or distinct x */
+ /* and y pointsizes), there are two possible scalings. */
+ /* */
+ /* A first try was to implement a `lazy' scheme where all values were */
+ /* scaled when first used. However, while some values are always used */
+ /* in the same direction, some others are used under many different */
+ /* circumstances and orientations. */
+ /* */
+ /* I have found a simpler way to do the same, and it even seems to work */
+ /* in most of the cases: */
+ /* */
+ /* - All CVT values are scaled to the maximum ppem size. */
+ /* */
+ /* - When performing a read or write in the CVT, a ratio factor is used */
+ /* to perform adequate scaling. Example: */
+ /* */
+ /* x_ppem = 14 */
+ /* y_ppem = 10 */
+ /* */
+ /* We choose ppem = x_ppem = 14 as the CVT scaling size. All cvt */
+ /* entries are scaled to it. */
+ /* */
+ /* x_ratio = 1.0 */
+ /* y_ratio = y_ppem/ppem (< 1.0) */
+ /* */
+ /* We compute the current ratio like: */
+ /* */
+ /* - If projVector is horizontal, */
+ /* ratio = x_ratio = 1.0 */
+ /* */
+ /* - if projVector is vertical, */
+ /* ratio = y_ratio */
+ /* */
+ /* - else, */
+ /* ratio = sqrt( (proj.x * x_ratio) ^ 2 + (proj.y * y_ratio) ^ 2 ) */
+ /* */
+ /* Reading a cvt value returns */
+ /* ratio * cvt[index] */
+ /* */
+ /* Writing a cvt value in pixels: */
+ /* cvt[index] / ratio */
+ /* */
+ /* The current ppem is simply */
