-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 © <year> The FreeType
-    Project (www.freetype.org).  All rights reserved.
-   """
-
-  Please replace <year> 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 [email protected]
-
-      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 [email protected]
-
-      Discusses bugs,  as well  as engine internals,  design issues,
-      specific licenses, porting, etc.

-   *
-   * @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 subpixel 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.

-   * <Title>
-   *    Cache Sub-System
-   *
-   * <Abstract>
-   *    How to cache face, size, and glyph data with FreeType~2.
-   *
-   * <Description>
-   *   This section describes the FreeType~2 cache sub-system, which is used
-   *   to limit the number of concurrently opened @FT_Face and @FT_Size
-   *   objects, as well as caching information like character maps and glyph
-   *   images while limiting their maximum memory usage.
-   *
-   *   Note that all types and functions begin with the `FTC_' prefix.
-   *
-   *   The cache is highly portable and thus doesn't know anything about the
-   *   fonts installed on your system, or how to access them.  This implies
-   *   the following scheme:
-   *
-   *   First, available or installed font faces are uniquely identified by
-   *   @FTC_FaceID values, provided to the cache by the client.  Note that
-   *   the cache only stores and compares these values, and doesn't try to
-   *   interpret them in any way.
-   *
-   *   Second, the cache calls, only when needed, a client-provided function
-   *   to convert an @FTC_FaceID into a new @FT_Face object.  The latter is
-   *   then completely managed by the cache, including its termination
-   *   through @FT_Done_Face.  To monitor termination of face objects, the
-   *   finalizer callback in the `generic' field of the @FT_Face object can
-   *   be used, which might also be used to store the @FTC_FaceID of the
-   *   face.
-   *
-   *   Clients are free to map face IDs to anything else.  The most simple
-   *   usage is to associate them to a (pathname,face_index) pair that is
-   *   used to call @FT_New_Face.  However, more complex schemes are also
-   *   possible.
-   *
-   *   Note that for the cache to work correctly, the face ID values must be
-   *   *persistent*, which means that the contents they point to should not
-   *   change at runtime, or that their value should not become invalid.
-   *
-   *   If this is unavoidable (e.g., when a font is uninstalled at runtime),
-   *   you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
-   *   the cache get rid of any references to the old @FTC_FaceID it may
-   *   keep internally.  Failure to do so will lead to incorrect behaviour
-   *   or even crashes.
-   *
-   *   To use the cache, start with calling @FTC_Manager_New to create a new
-   *   @FTC_Manager object, which models a single cache instance.  You can
-   *   then look up @FT_Face and @FT_Size objects with
-   *   @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
-   *
-   *   If you want to use the charmap caching, call @FTC_CMapCache_New, then
-   *   later use @FTC_CMapCache_Lookup to perform the equivalent of
-   *   @FT_Get_Char_Index, only much faster.
-   *
-   *   If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
-   *   later use @FTC_ImageCache_Lookup to retrieve the corresponding
-   *   @FT_Glyph objects from the cache.
-   *
-   *   If you need lots of small bitmaps, it is much more memory efficient

-   *
-   * @description:
-   *   An opaque pointer type that is used to identity face objects.  The
-   *   contents of such objects is application-dependent.
-   *
-   *   These pointers are typically used to point to a user-defined
-   *   structure containing a font file path, and face index.
-   *
-   * @note:
-   *   Never use NULL as a valid @FTC_FaceID.
-   *
-   *   Face IDs are passed by the client to the cache manager that calls,
-   *   when needed, the @FTC_Face_Requester to translate them into new
-   *   @FT_Face objects.
-   *
-   *   If the content of a given face ID changes at runtime, or if the value
-   *   becomes invalid (e.g., when uninstalling a font), you should
-   *   immediately call @FTC_Manager_RemoveFaceID before any other cache
-   *   function.
-   *
-   *   Failure to do so will result in incorrect behaviour or even
-   *   memory leaks and crashes.

-   *   The CFF driver

-   * @abstract:
-   *   Controlling the CFF driver module.
-   *
-   * @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 subpixels 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 subpixels 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.

-   *   The TrueType driver
-   *
-   * @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.

-   *
-   * @description:
-   *   All glyphs that pass through the auto-hinter will be emboldened
-   *   unless this property is set to TRUE.  The same is true for the CFF,
-   *   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
-   *   stems at smaller sizes, regardless of hinting, to enhance contrast. 
-   *   Setting this property, stem darkening gets switched off.
-   *
-   *   For the auto-hinter, stem-darkening is experimental currently and
-   *   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
-   *   down), the higher the loss of emboldening versus the CFF driver.
-   *
-   *   Note that stem darkening is never applied if @FT_LOAD_NO_SCALE is

-   *   The `version' field gives a rough orientation only, since some

-   *   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.

-   * @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.
-   *

-   *   hinting (omitting the error handling).

-   *
-   *   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.
-   *
-   *   The following example code demonstrates how to access it (omitting
-   *   the error handling).

-   *
-   * @description:
-   *   *Experimental* *only*
-   *
-   *   If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
-   *   activate the warp hinting code in the auto-hinter, this property
-   *   switches warping on and off.
-   *
-   *   Warping only works in `normal' auto-hinting mode replacing it.
-   *   The idea of the code is to slightly scale and shift a glyph along
-   *   the non-hinted dimension (which is usually the horizontal axis) so
-   *   that as much of its segments are aligned (more or less) to the grid.
-   *   To find out a glyph's optimal scaling and shifting value, various
-   *   parameter combinations are tried and scored.
-   *
-   *   By default, warping is off.  The example below shows how to switch on
-   *   warping (omitting the error handling).
-   *
-   *   {
-   *     FT_Library  library;
-   *     FT_Bool     warping = 1;
-   *
-   *
-   *     FT_Init_FreeType( &library );
-   *
-   *     FT_Property_Set( library, "autofitter",
-   *                               "warping", &warping );
-   *   }
-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable (using values 1 and 0 for `on' and `off', respectively).
-   *
-   *   The warping code can also change advance widths.  Have a look at the
-   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
-   *   for details on improving inter-glyph distances while rendering.
-   *
-   *   Since warping is a global property of the auto-hinter it is best to
-   *   change its value before rendering any face.  Otherwise, you should
-   *   reload all faces that get auto-hinted in `normal' hinting mode.
-   *
-   * @since:
-   *   2.6

-   * @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'.
-   *
-   * @since:
-   *   2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)

-  * @description:
-  *   Open a new stream to parse LZW-compressed font files.  This is
-  *   mainly used to support the compressed `*.pcf.Z' fonts that come
-  *   with XFree86.
-  *
-  * @input:
-  *   stream :: The target embedding stream.
-  *
-  *   source :: The source stream.
-  *
-  * @return:
-  *   FreeType error code.  0~means success.
-  *
-  * @note:
-  *   The source stream must be opened _before_ calling this function.
-  *
-  *   Calling the internal function `FT_Stream_Close' on the new stream will
-  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
-  *   objects will be released to the heap.
-  *
-  *   The stream implementation is very basic and resets the decompression
-  *   process each time seeking backwards is needed within the stream
-  *
-  *   In certain builds of the library, LZW compression recognition is
-  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
-  *   This means that if no font driver is capable of handling the raw
-  *   compressed file, the library will try to open a LZW stream from it
-  *   and re-open the face with it.
-  *
-  *   This function may return `FT_Err_Unimplemented_Feature' if your build
-  *   of FreeType was not compiled with LZW support.

-  *    `inside' borders of the stroke.
-  *
-  *    This can be useful to generate `bordered' glyph, i.e., glyphs
-  *    displayed with a coloured (and anti-aliased) border around their
-  *    shape.

-   *   FT_STROKER_LINEJOIN_BEVEL ::
-   *     Used to render beveled line joins.  The outer corner of
-   *     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

-   *     limit value and the border radius), then a bevel join (see
-   *     above) is used instead.  This prevents long spikes being

-   *     Used to render mitered line joins, with variable bevels if

-   *     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

-   * @enum:
-   *   FT_WinFNT_ID_XXX
-   *
-   * @description:
-   *   A list of valid values for the `charset' byte in
-   *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
-   *   encodings (except for cp1361) can be found at
-   *   ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
-   *   subdirectory.  cp1361 is roughly a superset of
-   *   MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
-   *
-   * @values:
-   *   FT_WinFNT_ID_DEFAULT ::
-   *     This is used for font enumeration and font creation as a
-   *     `don't care' value.  Valid font files don't contain this value.
-   *     When querying for information about the character set of the font
-   *     that is currently selected into a specified device context, this
-   *     return value (of the related Windows API) simply denotes failure.
-   *
-   *   FT_WinFNT_ID_SYMBOL ::
-   *     There is no known mapping table available.
-   *
-   *   FT_WinFNT_ID_MAC ::
-   *     Mac Roman encoding.
-   *
-   *   FT_WinFNT_ID_OEM ::
-   *     From Michael Poettgen <[email protected]>:
-   *
-   *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
-   *       is used for the charset of vector fonts, like `modern.fon',
-   *       `roman.fon', and `script.fon' on Windows.
-   *
-   *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
-   *       specifies a character set that is operating-system dependent.
-   *
-   *       The `IFIMETRICS' documentation from the `Windows Driver
-   *       Development Kit' says: This font supports an OEM-specific
-   *       character set.  The OEM character set is system dependent.
-   *
-   *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
-   *       second default codepage that most international versions of
-   *       Windows have.  It is one of the OEM codepages from
-   *
-   *         https://msdn.microsoft.com/en-us/goglobal/bb964655,
-   *
-   *       and is used for the `DOS boxes', to support legacy applications.
-   *       A German Windows version for example usually uses ANSI codepage
-   *       1252 and OEM codepage 850.
-   *
-   *   FT_WinFNT_ID_CP874 ::
-   *     A superset of Thai TIS 620 and ISO 8859-11.
-   *
-   *   FT_WinFNT_ID_CP932 ::
-   *     A superset of Japanese Shift-JIS (with minor deviations).
-   *
-   *   FT_WinFNT_ID_CP936 ::
-   *     A superset of simplified Chinese GB 2312-1980 (with different
-   *     ordering and minor deviations).
-   *
-   *   FT_WinFNT_ID_CP949 ::
-   *     A superset of Korean Hangul KS~C 5601-1987 (with different
-   *     ordering and minor deviations).
-   *
-   *   FT_WinFNT_ID_CP950 ::
-   *     A superset of traditional Chinese Big~5 ETen (with different
-   *     ordering and minor deviations).
-   *
-   *   FT_WinFNT_ID_CP1250 ::
-   *     A superset of East European ISO 8859-2 (with slightly different
-   *     ordering).
-   *
-   *   FT_WinFNT_ID_CP1251 ::
-   *     A superset of Russian ISO 8859-5 (with different ordering).
-   *
-   *   FT_WinFNT_ID_CP1252 ::
-   *     ANSI encoding.  A superset of ISO 8859-1.
-   *
-   *   FT_WinFNT_ID_CP1253 ::
-   *     A superset of Greek ISO 8859-7 (with minor modifications).
-   *
-   *   FT_WinFNT_ID_CP1254 ::
-   *     A superset of Turkish ISO 8859-9.
-   *
-   *   FT_WinFNT_ID_CP1255 ::
-   *     A superset of Hebrew ISO 8859-8 (with some modifications).
-   *
-   *   FT_WinFNT_ID_CP1256 ::
-   *     A superset of Arabic ISO 8859-6 (with different ordering).
-   *
-   *   FT_WinFNT_ID_CP1257 ::
-   *     A superset of Baltic ISO 8859-13 (with some deviations).
-   *
-   *   FT_WinFNT_ID_CP1258 ::
-   *     For Vietnamese.  This encoding doesn't cover all necessary
-   *     characters.
-   *
-   *   FT_WinFNT_ID_CP1361 ::
-   *     Korean (Johab).

-   *    Retrieve the value for the supplied key from a PostScript font.
-   *
-   * @input:
-   *    face ::
-   *       PostScript face handle.
-   *
-   *    key ::
-   *       An enumeration value representing the dictionary key to retrieve.
-   *
-   *    idx ::
-   *       For array values, this specifies the index to be returned.
-   *
-   *    value ::
-   *       A pointer to memory into which to write the value.
-   *
-   *    valen_len ::
-   *       The size, in bytes, of the memory supplied for the value.
-   *
-   * @output:
-   *    value ::
-   *       The value matching the above key, if it exists.
-   *
-   * @return:
-   *    The amount of memory (in bytes) required to hold the requested
-   *    value (if it exists, -1 otherwise).
-   *
-   * @note:
-   *    The values returned are not pointers into the internal structures of
-   *    the face, but are `fresh' copies, so that the memory containing them
-   *    belongs to the calling application.  This also enforces the
-   *    `read-only' nature of these values, i.e., this function cannot be
-   *    used to manipulate the face.
-   *
-   *    `value' is a void pointer because the values returned can be of
-   *    various types.
-   *
-   *    If either `value' is NULL or `value_len' is too small, just the
-   *    required memory size for the requested entry is returned.
-   *
-   *    The `idx' parameter is used, not only to retrieve elements of, for
-   *    example, the FontMatrix or FontBBox, but also to retrieve name keys
-   *    from the CharStrings dictionary, and the charstrings themselves.  It
-   *    is ignored for atomic values.
-   *
-   *    PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000.  To
-   *    get the value as in the font stream, you need to divide by
-   *    65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
-   *
-   *    IMPORTANT: Only key/value pairs read by the FreeType interpreter can
-   *    be retrieved.  So, for example, PostScript procedures such as NP,
-   *    ND, and RD are not available.  Arbitrary keys are, obviously, not be
-   *    available either.
-   *
-   *    If the font's format is not PostScript-based, this function returns
-   *    the `FT_Err_Invalid_Argument' error code.

-   * @since:
-   *    2.4.8

-   *     See @TT_MAC_ID_XXX for corresponding `encoding_id' values.  Note that
-   *     most TrueType fonts contain an Apple roman charmap to be usable on

-   *
-   *   TT_PLATFORM_ISO ::
-   *     This value was used to specify ISO/IEC 10646 charmaps.  It is however

-   *     `encoding_id' values.
-   *
-   *   TT_PLATFORM_MICROSOFT ::
-   *     Used by Microsoft to indicate Windows-specific charmaps.  See
-   *     @TT_MS_ID_XXX for a list of corresponding `encoding_id' values.
-   *     Note that most fonts contain a Unicode charmap using
-   *     (TT_PLATFORM_MICROSOFT, @TT_MS_ID_UNICODE_CS).
-   *
-   *   TT_PLATFORM_CUSTOM ::
-   *     Used to indicate application-specific charmaps.
-   *
-   *   TT_PLATFORM_ADOBE ::
-   *     This value isn't part of any font format specification, but is used
-   *     by FreeType to report Adobe-specific charmaps in an @FT_CharMapRec
-   *     structure.  See @TT_ADOBE_ID_XXX.

-   *   Possible values of the language identifier field in the name records
-   *   of the SFNT `name' table if the `platform' identifier code is
-   *   @TT_PLATFORM_MICROSOFT.  These values are also used as return values
-   *   for function @FT_Get_CMap_Language_ID.
-   *
-   *   The canonical source for Microsoft's IDs is
-   *
-   *     https://www.microsoft.com/globaldev/reference/lcid-all.mspx ,
-   *
-   *   however, we only provide macros for language identifiers present in
-   *   the OpenType specification: Microsoft has abandoned the concept of
-   *   LCIDs (language code identifiers), and format~1 of the `name' table
-   *   provides a better mechanism for languages not covered here.
-   *
-   *   More legacy values not listed in the reference can be found in the
-   *   @FT_TRUETYPE_IDS_H header file.

-   *
-   * @description:
-   *   Load any SFNT font table into client memory.
-   *
-   * @input:
-   *   face ::
-   *     A handle to the source face.
-   *
-   *   tag ::
-   *     The four-byte tag of the table to load.  Use value~0 if you want
-   *     to access the whole font file.  Otherwise, you can use one of the
-   *     definitions found in the @FT_TRUETYPE_TAGS_H file, or forge a new
-   *     one with @FT_MAKE_TAG.
-   *
-   *   offset ::
-   *     The starting offset in the table (or file if tag~==~0).
-   *
-   * @output:
-   *   buffer ::
-   *     The target buffer address.  The client must ensure that the memory
-   *     array is big enough to hold the data.
-   *
-   * @inout:
-   *   length ::
-   *     If the `length' parameter is NULL, try to load the whole table.
-   *     Return an error code if it fails.
-   *
-   *     Else, if `*length' is~0, exit immediately while returning the
-   *     table's (or file) full size in it.
-   *
-   *     Else the number of bytes to read from the table or file, from the
-   *     starting offset.
-   *
-   * @return:
-   *   FreeType error code.  0~means success.
-   *
-   * @note:
-   *   If you need to determine the table's length you should first call this
-   *   function with `*length' set to~0, as in the following example:
-   *
-   *     {
-   *       FT_ULong  length = 0;
-   *
-   *
-   *       error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );
-   *       if ( error ) { ... table does not exist ... }
-   *
-   *       buffer = malloc( length );
-   *       if ( buffer == NULL ) { ... not enough memory ... }
-   *
-   *       error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );
-   *       if ( error ) { ... could not load table ... }
-   *     }

-1. about
---------
-
-PNG is a file format to store raster images losslessly with good compression,
-supporting different color types and alpha channel.
-
-LodePNG is a PNG codec according to the Portable Network Graphics (PNG)
-Specification (Second Edition) - W3C Recommendation 10 November 2003.
-
-The specifications used are:
-
-*) Portable Network Graphics (PNG) Specification (Second Edition):
-     http://www.w3.org/TR/2003/REC-PNG-20031110
-*) RFC 1950 ZLIB Compressed Data Format version 3.3:
-     http://www.gzip.org/zlib/rfc-zlib.html
-*) RFC 1951 DEFLATE Compressed Data Format Specification ver 1.3:
-     http://www.gzip.org/zlib/rfc-deflate.html
-
-The most recent version of LodePNG can currently be found at
-http://lodev.org/lodepng/
-
-LodePNG works both in C (ISO C90) and C++, with a C++ wrapper that adds
-extra functionality.
-
-LodePNG exists out of two files:
--lodepng.h: the header file for both C and C++
--lodepng.c(pp): give it the name lodepng.c or lodepng.cpp (or .cc) depending on your usage
-
-If you want to start using LodePNG right away without reading this doc, get the
-examples from the LodePNG website to see how to use it in code, or check the
-smaller examples in chapter 13 here.
-
-LodePNG is simple but only supports the basic requirements. To achieve
-simplicity, the following design choices were made: There are no dependencies
-on any external library. There are functions to decode and encode a PNG with
-a single function call, and extended versions of these functions taking a
-LodePNGState struct allowing to specify or get more information. By default
-the colors of the raw image are always RGB or RGBA, no matter what color type
-the PNG file uses. To read and write files, there are simple functions to
-convert the files to/from buffers in memory.
-
-This all makes LodePNG suitable for loading textures in games, demos and small
-programs, ... It's less suitable for full fledged image editors, loading PNGs
-over network (it requires all the image data to be available before decoding can
-begin), life-critical systems, ...
-
-1.1. supported features
------------------------
-
-The following features are supported by the decoder:
-
-*) decoding of PNGs with any color type, bit depth and interlace mode, to a 24- or 32-bit color raw image,
-   or the same color type as the PNG
-*) encoding of PNGs, from any raw image to 24- or 32-bit color, or the same color type as the raw image
-*) Adam7 interlace and deinterlace for any color type
-*) loading the image from harddisk or decoding it from a buffer from other sources than harddisk
-*) support for alpha channels, including RGBA color model, translucent palettes and color keying
-*) zlib decompression (inflate)
-*) zlib compression (deflate)
-*) CRC32 and ADLER32 checksums
-*) colorimetric color profile conversions: currently experimentally available in lodepng_util.cpp only,
-   plus alternatively ability to pass on chroma/gamma/ICC profile information to other color management system.
-*) handling of unknown chunks, allowing making a PNG editor that stores custom and unknown chunks.
-*) the following chunks are supported by both encoder and decoder:
-    IHDR: header information
-    PLTE: color palette
-    IDAT: pixel data
-    IEND: the final chunk
-    tRNS: transparency for palettized images
-    tEXt: textual information
-    zTXt: compressed textual information
-    iTXt: international textual information
-    bKGD: suggested background color
-    pHYs: physical dimensions
-    tIME: modification time
-    cHRM: RGB chromaticities
-    gAMA: RGB gamma correction
-    iCCP: ICC color profile
-    sRGB: rendering intent
-
-1.2. features not supported
----------------------------
-
-The following features are _not_ supported:
-
-*) some features needed to make a conformant PNG-Editor might be still missing.
-*) partial loading/stream processing. All data must be available and is processed in one call.
-*) The following public chunks are not (yet) supported but treated as unknown chunks by LodePNG:
-    sBIT
-    hIST
-    sPLT
-
-
-2. C and C++ version
---------------------
-
-The C version uses buffers allocated with alloc that you need to free()
-yourself. You need to use init and cleanup functions for each struct whenever
-using a struct from the C version to avoid exploits and memory leaks.
-
-The C++ version has extra functions with std::vectors in the interface and the
-lodepng::State class which is a LodePNGState with constructor and destructor.
-
-These files work without modification for both C and C++ compilers because all
-the additional C++ code is in "#ifdef __cplusplus" blocks that make C-compilers
-ignore it, and the C code is made to compile both with strict ISO C90 and C++.
-
-To use the C++ version, you need to rename the source file to lodepng.cpp
-(instead of lodepng.c), and compile it with a C++ compiler.
-
-To use the C version, you need to rename the source file to lodepng.c (instead
-of lodepng.cpp), and compile it with a C compiler.
-
-
-3. Security
------------
-
-Even if carefully designed, it's always possible that LodePNG contains possible
-exploits. If you discover one, please let me know, and it will be fixed.
-
-When using LodePNG, care has to be taken with the C version of LodePNG, as well
-as the C-style structs when working with C++. The following conventions are used
-for all C-style structs:
-
--if a struct has a corresponding init function, always call the init function when making a new one
--if a struct has a corresponding cleanup function, call it before the struct disappears to avoid memory leaks
--if a struct has a corresponding copy function, use the copy function instead of "=".
- The destination must also be inited already.
-
-
-4. Decoding
------------
-
-Decoding converts a PNG compressed image to a raw pixel buffer.
-
-Most documentation on using the decoder is at its declarations in the header
-above. For C, simple decoding can be done with functions such as
-lodepng_decode32, and more advanced decoding can be done with the struct
-LodePNGState and lodepng_decode. For C++, all decoding can be done with the
-various lodepng::decode functions, and lodepng::State can be used for advanced
-features.
-
-When using the LodePNGState, it uses the following fields for decoding:
-*) LodePNGInfo info_png: it stores extra information about the PNG (the input) in here
-*) LodePNGColorMode info_raw: here you can say what color mode of the raw image (the output) you want to get
-*) LodePNGDecoderSettings decoder: you can specify a few extra settings for the decoder to use
-
-LodePNGInfo info_png
---------------------
-
-After decoding, this contains extra information of the PNG image, except the actual
-pixels, width and height because these are already gotten directly from the decoder
-functions.
-
-It contains for example the original color type of the PNG image, text comments,
-suggested background color, etc... More details about the LodePNGInfo struct are
-at its declaration documentation.
-
-LodePNGColorMode info_raw
--------------------------
-
-When decoding, here you can specify which color type you want
-the resulting raw image to be. If this is different from the colortype of the
-PNG, then the decoder will automatically convert the result. This conversion
-always works, except if you want it to convert a color PNG to grayscale or to
-a palette with missing colors.
-
-By default, 32-bit color is used for the result.
-
-LodePNGDecoderSettings decoder
-------------------------------
-
-The settings can be used to ignore the errors created by invalid CRC and Adler32
-chunks, and to disable the decoding of tEXt chunks.
-
-There's also a setting color_convert, true by default. If false, no conversion
-is done, the resulting data will be as it was in the PNG (after decompression)
-and you'll have to puzzle the colors of the pixels together yourself using the
-color type information in the LodePNGInfo.
-
-
-5. Encoding
------------
-
-Encoding converts a raw pixel buffer to a PNG compressed image.
-
-Most documentation on using the encoder is at its declarations in the header
-above. For C, simple encoding can be done with functions such as
-lodepng_encode32, and more advanced decoding can be done with the struct
-LodePNGState and lodepng_encode. For C++, all encoding can be done with the
-various lodepng::encode functions, and lodepng::State can be used for advanced
-features.
-
-Like the decoder, the encoder can also give errors. However it gives less errors
-since the encoder input is trusted, the decoder input (a PNG image that could
-be forged by anyone) is not trusted.
-
-When using the LodePNGState, it uses the following fields for encoding:
-*) LodePNGInfo info_png: here you specify how you want the PNG (the output) to be.
-*) LodePNGColorMode info_raw: here you say what color type of the raw image (the input) has
-*) LodePNGEncoderSettings encoder: you can specify a few settings for the encoder to use
-
-LodePNGInfo info_png
---------------------
-
-When encoding, you use this the opposite way as when decoding: for encoding,
-you fill in the values you want the PNG to have before encoding. By default it's
-not needed to specify a color type for the PNG since it's automatically chosen,
-but it's possible to choose it yourself given the right settings.
-
-The encoder will not always exactly match the LodePNGInfo struct you give,
-it tries as close as possible. Some things are ignored by the encoder. The
-encoder uses, for example, the following settings from it when applicable:
-colortype and bitdepth, text chunks, time chunk, the color key, the palette, the
-background color, the interlace method, unknown chunks, ...
-
-When encoding to a PNG with colortype 3, the encoder will generate a PLTE chunk.
-If the palette contains any colors for which the alpha channel is not 255 (so
-there are translucent colors in the palette), it'll add a tRNS chunk.
-
-LodePNGColorMode info_raw
--------------------------
-
-You specify the color type of the raw image that you give to the input here,
-including a possible transparent color key and palette you happen to be using in
-your raw image data.
-
-By default, 32-bit color is assumed, meaning your input has to be in RGBA
-format with 4 bytes (unsigned chars) per pixel.
-
-LodePNGEncoderSettings encoder
-------------------------------
-
-The following settings are supported (some are in sub-structs):
-*) auto_convert: when this option is enabled, the encoder will
-automatically choose the smallest possible color mode (including color key) that
-can encode the colors of all pixels without information loss.
-*) btype: the block type for LZ77. 0 = uncompressed, 1 = fixed huffman tree,
-   2 = dynamic huffman tree (best compression). Should be 2 for proper
-   compression.
-*) use_lz77: whether or not to use LZ77 for compressed block types. Should be
-   true for proper compression.
-*) windowsize: the window size used by the LZ77 encoder (1 - 32768). Has value
-   2048 by default, but can be set to 32768 for better, but slow, compression.
-*) force_palette: if colortype is 2 or 6, you can make the encoder write a PLTE
-   chunk if force_palette is true. This can used as suggested palette to convert
-   to by viewers that don't support more than 256 colors (if those still exist)
-*) add_id: add text chunk "Encoder: LodePNG <version>" to the image.
-*) text_compression: default 1. If 1, it'll store texts as zTXt instead of tEXt chunks.
-  zTXt chunks use zlib compression on the text. This gives a smaller result on
-  large texts but a larger result on small texts (such as a single program name).
-  It's all tEXt or all zTXt though, there's no separate setting per text yet.
-
-
-6. color conversions
---------------------
-
-An important thing to note about LodePNG, is that the color type of the PNG, and
-the color type of the raw image, are completely independent. By default, when
-you decode a PNG, you get the result as a raw image in the color type you want,
-no matter whether the PNG was encoded with a palette, grayscale or RGBA color.
-And if you encode an image, by default LodePNG will automatically choose the PNG
-color type that gives good compression based on the values of colors and amount
-of colors in the image. It can be configured to let you control it instead as
-well, though.
-
-To be able to do this, LodePNG does conversions from one color mode to another.
-It can convert from almost any color type to any other color type, except the
-following conversions: RGB to grayscale is not supported, and converting to a
-palette when the palette doesn't have a required color is not supported. This is
-not supported on purpose: this is information loss which requires a color
-reduction algorithm that is beyong the scope of a PNG encoder (yes, RGB to gray
-is easy, but there are multiple ways if you want to give some channels more
-weight).
-
-By default, when decoding, you get the raw image in 32-bit RGBA or 24-bit RGB
-color, no matter what color type the PNG has. And by default when encoding,
-LodePNG automatically picks the best color model for the output PNG, and expects
-the input image to be 32-bit RGBA or 24-bit RGB. So, unless you want to control
-the color format of the images yourself, you can skip this chapter.
-
-6.1. PNG color types
---------------------
-
-A PNG image can have many color types, ranging from 1-bit color to 64-bit color,
-as well as palettized color modes. After the zlib decompression and unfiltering
-in the PNG image is done, the raw pixel data will have that color type and thus
-a certain amount of bits per pixel. If you want the output raw image after
-decoding to have another color type, a conversion is done by LodePNG.
-
-The PNG specification gives the following color types:
-
-0: grayscale, bit depths 1, 2, 4, 8, 16
-2: RGB, bit depths 8 and 16
-3: palette, bit depths 1, 2, 4 and 8
-4: grayscale with alpha, bit depths 8 and 16
-6: RGBA, bit depths 8 and 16
-
-Bit depth is the amount of bits per pixel per color channel. So the total amount
-of bits per pixel is: amount of channels * bitdepth.
-
-6.2. color conversions
-----------------------
-
-As explained in the sections about the encoder and decoder, you can specify
-color types and bit depths in info_png and info_raw to change the default
-behaviour.
-
-If, when decoding, you want the raw image to be something else than the default,
-you need to set the color type and bit depth you want in the LodePNGColorMode,
-or the parameters colortype and bitdepth of the simple decoding function.
-
-If, when encoding, you use another color type than the default in the raw input
-image, you need to specify its color type and bit depth in the LodePNGColorMode
-of the raw image, or use the parameters colortype and bitdepth of the simple
-encoding function.
-
-If, when encoding, you don't want LodePNG to choose the output PNG color type
-but control it yourself, you need to set auto_convert in the encoder settings
-to false, and specify the color type you want in the LodePNGInfo of the
-encoder (including palette: it can generate a palette if auto_convert is true,
-otherwise not).
-
-If the input and output color type differ (whether user chosen or auto chosen),
-LodePNG will do a color conversion, which follows the rules below, and may
-sometimes result in an error.
-
-To avoid some confusion:
--the decoder converts from PNG to raw image
--the encoder converts from raw image to PNG
--the colortype and bitdepth in LodePNGColorMode info_raw, are those of the raw image
--the colortype and bitdepth in the color field of LodePNGInfo info_png, are those of the PNG
--when encoding, the color type in LodePNGInfo is ignored if auto_convert
- is enabled, it is automatically generated instead
--when decoding, the color type in LodePNGInfo is set by the decoder to that of the original
- PNG image, but it can be ignored since the raw image has the color type you requested instead
--if the color type of the LodePNGColorMode and PNG image aren't the same, a conversion
- between the color types is done if the color types are supported. If it is not
- supported, an error is returned. If the types are the same, no conversion is done.
--even though some conversions aren't supported, LodePNG supports loading PNGs from any
- colortype and saving PNGs to any colortype, sometimes it just requires preparing
- the raw image correctly before encoding.
--both encoder and decoder use the same color converter.
-
-The function lodepng_convert does the color conversion. It is available in the
-interface but normally isn't needed since the encoder and decoder already call
-it.
-
-Non supported color conversions:
--color to grayscale when non-gray pixels are present: no error is thrown, but
-the result will look ugly because only the red channel is taken (it assumes all
-three channels are the same in this case so ignores green and blue). The reason
-no error is given is to allow converting from three-channel grayscale images to
-one-channel even if there are numerical imprecisions.
--anything to palette when the palette does not have an exact match for a from-color
-in it: in this case an error is thrown
-
-Supported color conversions:
--anything to 8-bit RGB, 8-bit RGBA, 16-bit RGB, 16-bit RGBA
--any gray or gray+alpha, to gray or gray+alpha
--anything to a palette, as long as the palette has the requested colors in it
--removing alpha channel
--higher to smaller bitdepth, and vice versa
-
-If you want no color conversion to be done (e.g. for speed or control):
--In the encoder, you can make it save a PNG with any color type by giving the
-raw color mode and LodePNGInfo the same color mode, and setting auto_convert to
-false.
--In the decoder, you can make it store the pixel data in the same color type
-as the PNG has, by setting the color_convert setting to false. Settings in
-info_raw are then ignored.
-
-6.3. padding bits
------------------
-
-In the PNG file format, if a less than 8-bit per pixel color type is used and the scanlines
-have a bit amount that isn't a multiple of 8, then padding bits are used so that each
-scanline starts at a fresh byte. But that is NOT true for the LodePNG raw input and output.
-The raw input image you give to the encoder, and the raw output image you get from the decoder
-will NOT have these padding bits, e.g. in the case of a 1-bit image with a width
-of 7 pixels, the first pixel of the second scanline will the the 8th bit of the first byte,
-not the first bit of a new byte.
-
-6.4. A note about 16-bits per channel and endianness
-----------------------------------------------------
-
-LodePNG uses unsigned char arrays for 16-bit per channel colors too, just like
-for any other color format. The 16-bit values are stored in big endian (most
-significant byte first) in these arrays. This is the opposite order of the
-little endian used by x86 CPU's.
-
-LodePNG always uses big endian because the PNG file format does so internally.
-Conversions to other formats than PNG uses internally are not supported by
-LodePNG on purpose, there are myriads of formats, including endianness of 16-bit
-colors, the order in which you store R, G, B and A, and so on. Supporting and
-converting to/from all that is outside the scope of LodePNG.
-
-This may mean that, depending on your use case, you may want to convert the big
-endian output of LodePNG to little endian with a for loop. This is certainly not
-always needed, many applications and libraries support big endian 16-bit colors
-anyway, but it means you cannot simply cast the unsigned char* buffer to an
-unsigned short* buffer on x86 CPUs.
-
-
-7. error values
----------------
-
-All functions in LodePNG that return an error code, return 0 if everything went
-OK, or a non-zero code if there was an error.
-
-The meaning of the LodePNG error values can be retrieved with the function
-lodepng_error_text: given the numerical error code, it returns a description
-of the error in English as a string.
-
-Check the implementation of lodepng_error_text to see the meaning of each code.
-
-
-8. chunks and PNG editing
--------------------------
-
-If you want to add extra chunks to a PNG you encode, or use LodePNG for a PNG
-editor that should follow the rules about handling of unknown chunks, or if your
-program is able to read other types of chunks than the ones handled by LodePNG,
-then that's possible with the chunk functions of LodePNG.
-
-A PNG chunk has the following layout:
-
-4 bytes length
-4 bytes type name
-length bytes data
-4 bytes CRC
-
-8.1. iterating through chunks
------------------------------
-
-If you have a buffer containing the PNG image data, then the first chunk (the
-IHDR chunk) starts at byte number 8 of that buffer. The first 8 bytes are the
-signature of the PNG and are not part of a chunk. But if you start at byte 8
-then you have a chunk, and can check the following things of it.
-
-NOTE: none of these functions check for memory buffer boundaries. To avoid
-exploits, always make sure the buffer contains all the data of the chunks.
-When using lodepng_chunk_next, make sure the returned value is within the
-allocated memory.
-
-unsigned lodepng_chunk_length(const unsigned char* chunk):
-
-Get the length of the chunk's data. The total chunk length is this length + 12.
-
-void lodepng_chunk_type(char type[5], const unsigned char* chunk):
-unsigned char lodepng_chunk_type_equals(const unsigned char* chunk, const char* type):
-
-Get the type of the chunk or compare if it's a certain type
-
-unsigned char lodepng_chunk_critical(const unsigned char* chunk):
-unsigned char lodepng_chunk_private(const unsigned char* chunk):
-unsigned char lodepng_chunk_safetocopy(const unsigned char* chunk):
-
-Check if the chunk is critical in the PNG standard (only IHDR, PLTE, IDAT and IEND are).
-Check if the chunk is private (public chunks are part of the standard, private ones not).
-Check if the chunk is safe to copy. If it's not, then, when modifying data in a critical
-chunk, unsafe to copy chunks of the old image may NOT be saved in the new one if your
-program doesn't handle that type of unknown chunk.
-
-unsigned char* lodepng_chunk_data(unsigned char* chunk):
-const unsigned char* lodepng_chunk_data_const(const unsigned char* chunk):
-
-Get a pointer to the start of the data of the chunk.
-
-unsigned lodepng_chunk_check_crc(const unsigned char* chunk):
-void lodepng_chunk_generate_crc(unsigned char* chunk):
-
-Check if the crc is correct or generate a correct one.
-
-unsigned char* lodepng_chunk_next(unsigned char* chunk):
-const unsigned char* lodepng_chunk_next_const(const unsigned char* chunk):
-
-Iterate to the next chunk. This works if you have a buffer with consecutive chunks. Note that these
-functions do no boundary checking of the allocated data whatsoever, so make sure there is enough
-data available in the buffer to be able to go to the next chunk.
-
-unsigned lodepng_chunk_append(unsigned char** out, size_t* outlength, const unsigned char* chunk):
-unsigned lodepng_chunk_create(unsigned char** out, size_t* outlength, unsigned length,
-                              const char* type, const unsigned char* data):
-
-These functions are used to create new chunks that are appended to the data in *out that has
-length *outlength. The append function appends an existing chunk to the new data. The create
-function creates a new chunk with the given parameters and appends it. Type is the 4-letter
-name of the chunk.
-
-8.2. chunks in info_png
------------------------
-
-The LodePNGInfo struct contains fields with the unknown chunk in it. It has 3
-buffers (each with size) to contain 3 types of unknown chunks:
-the ones that come before the PLTE chunk, the ones that come between the PLTE
-and the IDAT chunks, and the ones that come after the IDAT chunks.
-It's necessary to make the distionction between these 3 cases because the PNG
-standard forces to keep the ordering of unknown chunks compared to the critical
-chunks, but does not force any other ordering rules.
-
-info_png.unknown_chunks_data[0] is the chunks before PLTE
-info_png.unknown_chunks_data[1] is the chunks after PLTE, before IDAT
-info_png.unknown_chunks_data[2] is the chunks after IDAT
-
-The chunks in these 3 buffers can be iterated through and read by using the same
-way described in the previous subchapter.
-
-When using the decoder to decode a PNG, you can make it store all unknown chunks
-if you set the option settings.remember_unknown_chunks to 1. By default, this
-option is off (0).
-
-The encoder will always encode unknown chunks that are stored in the info_png.
-If you need it to add a particular chunk that isn't known by LodePNG, you can
-use lodepng_chunk_append or lodepng_chunk_create to the chunk data in
-info_png.unknown_chunks_data[x].
-
-Chunks that are known by LodePNG should not be added in that way. E.g. to make
-LodePNG add a bKGD chunk, set background_defined to true and add the correct
-parameters there instead.
-
-
-9. compiler support
--------------------
-
-No libraries other than the current standard C library are needed to compile
-LodePNG. For the C++ version, only the standard C++ library is needed on top.
-Add the files lodepng.c(pp) and lodepng.h to your project, include
-lodepng.h where needed, and your program can read/write PNG files.
-
-It is compatible with C90 and up, and C++03 and up.
-
-If performance is important, use optimization when compiling! For both the
-encoder and decoder, this makes a large difference.
-
-Make sure that LodePNG is compiled with the same compiler of the same version
-and with the same settings as the rest of the program, or the interfaces with
-std::vectors and std::strings in C++ can be incompatible.
-
-CHAR_BITS must be 8 or higher, because LodePNG uses unsigned chars for octets.
-
-*) gcc and g++
-
-LodePNG is developed in gcc so this compiler is natively supported. It gives no
-warnings with compiler options "-Wall -Wextra -pedantic -ansi", with gcc and g++
-version 4.7.1 on Linux, 32-bit and 64-bit.
-
-*) Clang
-
-Fully supported and warning-free.
-
-*) Mingw
-
-The Mingw compiler (a port of gcc for Windows) should be fully supported by
-LodePNG.
-
-*) Visual Studio and Visual C++ Express Edition
-
-LodePNG should be warning-free with warning level W4. Two warnings were disabled
-with pragmas though: warning 4244 about implicit conversions, and warning 4996
-where it wants to use a non-standard function fopen_s instead of the standard C
-fopen.
-
-Visual Studio may want "stdafx.h" files to be included in each source file and
-give an error "unexpected end of file while looking for precompiled header".
-This is not standard C++ and will not be added to the stock LodePNG. You can
-disable it for lodepng.cpp only by right clicking it, Properties, C/C++,
-Precompiled Headers, and set it to Not Using Precompiled Headers there.
-
-NOTE: Modern versions of VS should be fully supported, but old versions, e.g.
-VS6, are not guaranteed to work.
-
-*) Compilers on Macintosh
-
-LodePNG has been reported to work both with gcc and LLVM for Macintosh, both for
-C and C++.
-
-*) Other Compilers
-
-If you encounter problems on any compilers, feel free to let me know and I may
-try to fix it if the compiler is modern and standards complient.
-
-
-10. examples

-12. changes
------------
-
-The version number of LodePNG is the date of the change given in the format
-yyyymmdd.
-
-Some changes aren't backwards compatible. Those are indicated with a (!)
-symbol.
-
-*) 30 dec 2018: code style changes only: removed newlines before opening braces.
-*) 10 sep 2018: added way to inspect metadata chunks without full decoding.
-*) 19 aug 2018 (!): fixed color mode bKGD is encoded with and made it use
-   palette index in case of palette.
-*) 10 aug 2018 (!): added support for gAMA, cHRM, sRGB and iCCP chunks. This
-   change is backwards compatible unless you relied on unknown_chunks for those.
-*) 11 jun 2018: less restrictive check for pixel size integer overflow
-*) 14 jan 2018: allow optionally ignoring a few more recoverable errors
-*) 17 sep 2017: fix memory leak for some encoder input error cases
-*) 27 nov 2016: grey+alpha auto color model detection bugfix
-*) 18 apr 2016: Changed qsort to custom stable sort (for platforms w/o qsort).
-*) 09 apr 2016: Fixed colorkey usage detection, and better file loading (within
-   the limits of pure C90).
-*) 08 dec 2015: Made load_file function return error if file can't be opened.
-*) 24 okt 2015: Bugfix with decoding to palette output.
-*) 18 apr 2015: Boundary PM instead of just package-merge for faster encoding.
-*) 23 aug 2014: Reduced needless memory usage of decoder.
-*) 28 jun 2014: Removed fix_png setting, always support palette OOB for
-    simplicity. Made ColorProfile public.
-*) 09 jun 2014: Faster encoder by fixing hash bug and more zeros optimization.
-*) 22 dec 2013: Power of two windowsize required for optimization.
-*) 15 apr 2013: Fixed bug with LAC_ALPHA and color key.
-*) 25 mar 2013: Added an optional feature to ignore some PNG errors (fix_png).
-*) 11 mar 2013 (!): Bugfix with custom free. Changed from "my" to "lodepng_"
-    prefix for the custom allocators and made it possible with a new #define to
-    use custom ones in your project without needing to change lodepng's code.
-*) 28 jan 2013: Bugfix with color key.
-*) 27 okt 2012: Tweaks in text chunk keyword length error handling.
-*) 8 okt 2012 (!): Added new filter strategy (entropy) and new auto color mode.
-    (no palette). Better deflate tree encoding. New compression tweak settings.
-    Faster color conversions while decoding. Some internal cleanups.
-*) 23 sep 2012: Reduced warnings in Visual Studio a little bit.
-*) 1 sep 2012 (!): Removed #define's for giving custom (de)compression functions
-    and made it work with function pointers instead.
-*) 23 jun 2012: Added more filter strategies. Made it easier to use custom alloc
-    and free functions and toggle #defines from compiler flags. Small fixes.
-*) 6 may 2012 (!): Made plugging in custom zlib/deflate functions more flexible.
-*) 22 apr 2012 (!): Made interface more consistent, renaming a lot. Removed
-    redundant C++ codec classes. Reduced amount of structs. Everything changed,
-    but it is cleaner now imho and functionality remains the same. Also fixed
-    several bugs and shrunk the implementation code. Made new samples.
-*) 6 nov 2011 (!): By default, the encoder now automatically chooses the best
-    PNG color model and bit depth, based on the amount and type of colors of the
-    raw image. For this, autoLeaveOutAlphaChannel replaced by auto_choose_color.
-*) 9 okt 2011: simpler hash chain implementation for the encoder.
-*) 8 sep 2011: lz77 encoder lazy matching instead of greedy matching.
-*) 23 aug 2011: tweaked the zlib compression parameters after benchmarking.
-    A bug with the PNG filtertype heuristic was fixed, so that it chooses much
-    better ones (it's quite significant). A setting to do an experimental, slow,
-    brute force search for PNG filter types is added.
-*) 17 aug 2011 (!): changed some C zlib related function names.
-*) 16 aug 2011: made the code less wide (max 120 characters per line).
-*) 17 apr 2011: code cleanup. Bugfixes. Convert low to 16-bit per sample colors.
-*) 21 feb 2011: fixed compiling for C90. Fixed compiling with sections disabled.
-*) 11 dec 2010: encoding is made faster, based on suggestion by Peter Eastman
-    to optimize long sequences of zeros.
-*) 13 nov 2010: added LodePNG_InfoColor_hasPaletteAlpha and
-    LodePNG_InfoColor_canHaveAlpha functions for convenience.
-*) 7 nov 2010: added LodePNG_error_text function to get error code description.
-*) 30 okt 2010: made decoding slightly faster
-*) 26 okt 2010: (!) changed some C function and struct names (more consistent).
-     Reorganized the documentation and the declaration order in the header.
-*) 08 aug 2010: only changed some comments and external samples.
-*) 05 jul 2010: fixed bug thanks to warnings in the new gcc version.
-*) 14 mar 2010: fixed bug where too much memory was allocated for char buffers.
-*) 02 sep 2008: fixed bug where it could create empty tree that linux apps could
-    read by ignoring the problem but windows apps couldn't.
-*) 06 jun 2008: added more error checks for out of memory cases.
-*) 26 apr 2008: added a few more checks here and there to ensure more safety.
-*) 06 mar 2008: crash with encoding of strings fixed
-*) 02 feb 2008: support for international text chunks added (iTXt)
-*) 23 jan 2008: small cleanups, and #defines to divide code in sections
-*) 20 jan 2008: support for unknown chunks allowing using LodePNG for an editor.
-*) 18 jan 2008: support for tIME and pHYs chunks added to encoder and decoder.
-*) 17 jan 2008: ability to encode and decode compressed zTXt chunks added
-    Also various fixes, such as in the deflate and the padding bits code.
-*) 13 jan 2008: Added ability to encode Adam7-interlaced images. Improved
-    filtering code of encoder.
-*) 07 jan 2008: (!) changed LodePNG to use ISO C90 instead of C++. A
-    C++ wrapper around this provides an interface almost identical to before.
-    Having LodePNG be pure ISO C90 makes it more portable. The C and C++ code
-    are together in these files but it works both for C and C++ compilers.
-*) 29 dec 2007: (!) changed most integer types to unsigned int + other tweaks
-*) 30 aug 2007: bug fixed which makes this Borland C++ compatible
-*) 09 aug 2007: some VS2005 warnings removed again
-*) 21 jul 2007: deflate code placed in new namespace separate from zlib code
-*) 08 jun 2007: fixed bug with 2- and 4-bit color, and small interlaced images
-*) 04 jun 2007: improved support for Visual Studio 2005: crash with accessing
-    invalid std::vector element [0] fixed, and level 3 and 4 warnings removed
-*) 02 jun 2007: made the encoder add a tag with version by default
-*) 27 may 2007: zlib and png code separated (but still in the same file),
-    simple encoder/decoder functions added for more simple usage cases
-*) 19 may 2007: minor fixes, some code cleaning, new error added (error 69),
-    moved some examples from here to lodepng_examples.cpp
-*) 12 may 2007: palette decoding bug fixed
-*) 24 apr 2007: changed the license from BSD to the zlib license
-*) 11 mar 2007: very simple addition: ability to encode bKGD chunks.
-*) 04 mar 2007: (!) tEXt chunk related fixes, and support for encoding
-    palettized PNG images. Plus little interface change with palette and texts.
-*) 03 mar 2007: Made it encode dynamic Huffman shorter with repeat codes.
-    Fixed a bug where the end code of a block had length 0 in the Huffman tree.
-*) 26 feb 2007: Huffman compression with dynamic trees (BTYPE 2) now implemented
-    and supported by the encoder, resulting in smaller PNGs at the output.
-*) 27 jan 2007: Made the Adler-32 test faster so that a timewaste is gone.
-*) 24 jan 2007: gave encoder an error interface. Added color conversion from any
-    greyscale type to 8-bit greyscale with or without alpha.
-*) 21 jan 2007: (!) Totally changed the interface. It allows more color types
-    to convert to and is more uniform. See the manual for how it works now.
-*) 07 jan 2007: Some cleanup & fixes, and a few changes over the last days:
-    encode/decode custom tEXt chunks, separate classes for zlib & deflate, and
-    at last made the decoder give errors for incorrect Adler32 or Crc.
-*) 01 jan 2007: Fixed bug with encoding PNGs with less than 8 bits per channel.
-*) 29 dec 2006: Added support for encoding images without alpha channel, and
-    cleaned out code as well as making certain parts faster.
-*) 28 dec 2006: Added "Settings" to the encoder.
-*) 26 dec 2006: The encoder now does LZ77 encoding and produces much smaller files now.
-    Removed some code duplication in the decoder. Fixed little bug in an example.
-*) 09 dec 2006: (!) Placed output parameters of public functions as first parameter.
-    Fixed a bug of the decoder with 16-bit per color.
-*) 15 okt 2006: Changed documentation structure
-*) 09 okt 2006: Encoder class added. It encodes a valid PNG image from the
-    given image buffer, however for now it's not compressed.
-*) 08 sep 2006: (!) Changed to interface with a Decoder class
-*) 30 jul 2006: (!) LodePNG_InfoPng , width and height are now retrieved in different
-    way. Renamed decodePNG to decodePNGGeneric.
-*) 29 jul 2006: (!) Changed the interface: image info is now returned as a
-    struct of type LodePNG::LodePNG_Info, instead of a vector, which was a bit clumsy.
-*) 28 jul 2006: Cleaned the code and added new error checks.
-    Corrected terminology "deflate" into "inflate".
-*) 23 jun 2006: Added SDL example in the documentation in the header, this
-    example allows easy debugging by displaying the PNG and its transparency.
-*) 22 jun 2006: (!) Changed way to obtain error value. Added
-    loadFile function for convenience. Made decodePNG32 faster.
-*) 21 jun 2006: (!) Changed type of info vector to unsigned.
-    Changed position of palette in info vector. Fixed an important bug that
-    happened on PNGs with an uncompressed block.
-*) 16 jun 2006: Internally changed unsigned into unsigned where
-    needed, and performed some optimizations.
-*) 07 jun 2006: (!) Renamed functions to decodePNG and placed them
-    in LodePNG namespace. Changed the order of the parameters. Rewrote the
-    documentation in the header. Renamed files to lodepng.cpp and lodepng.h
-*) 22 apr 2006: Optimized and improved some code
-*) 07 sep 2005: (!) Changed to std::vector interface
-*) 12 aug 2005: Initial release (C++, decoder only)

-
-	If you return 'true' from a Visit method, recursive parsing will continue. If you return

-/**
-	A XMLHandle is a class that wraps a node pointer with null checks; this is
-	an incredibly useful thing. Note that XMLHandle is not part of the TinyXML-2
-	DOM structure. It is a separate utility class.
-
-	Take an example:
-	@verbatim
-	<Document>
-		<Element attributeA = "valueA">
-			<Child attributeB = "value1" />
-			<Child attributeB = "value2" />
-		</Element>
-	</Document>
-	@endverbatim
-
-	Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
-	easy to write a *lot* of code that looks like:
-
-	@verbatim
-	XMLElement* root = document.FirstChildElement( "Document" );
-	if ( root )
-	{
-		XMLElement* element = root->FirstChildElement( "Element" );
-		if ( element )
-		{
-			XMLElement* child = element->FirstChildElement( "Child" );
-			if ( child )
-			{
-				XMLElement* child2 = child->NextSiblingElement( "Child" );
-				if ( child2 )
-				{
-					// Finally do something useful.
-	@endverbatim
-
-	And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
-	of such code. A XMLHandle checks for null pointers so it is perfectly safe
-	and correct to use:
-
-	@verbatim
-	XMLHandle docHandle( &document );
-	XMLElement* child2 = docHandle.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();
-	if ( child2 )
-	{
-		// do something useful
-	@endverbatim
-
-	Which is MUCH more concise and useful.
-
-	It is also safe to copy handles - internally they are nothing more than node pointers.
-	@verbatim
-	XMLHandle handleCopy = handle;
-	@endverbatim
-
-	See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.
