+FREETYPE LICENSES
+-----------------
+
+The FreeType  2 font  engine is  copyrighted work  and cannot  be used
+legally without  a software  license.  In order  to make  this project
+usable to  a vast majority of  developers, we distribute it  under two
+mutually exclusive open-source licenses.
+
+This means that *you* must choose  *one* of the two licenses described
+below, then obey all its terms and conditions when using FreeType 2 in
+any of your projects or products.
+
+  - The FreeType License,  found in the file  `docs/FTL.TXT`, which is
+    similar to the  original BSD license *with*  an advertising clause
+    that forces  you to explicitly  cite the FreeType project  in your
+    product's  documentation.  All  details are  in the  license file.
+    This license is suited to products which don't use the GNU General
+    Public License.
+
+    Note that  this license  is compatible to  the GNU  General Public
+    License version 3, but not version 2.
+
+  - The   GNU   General   Public   License   version   2,   found   in
+    `docs/GPLv2.TXT`  (any  later  version  can  be  used  also),  for
+    programs  which  already  use  the  GPL.  Note  that  the  FTL  is
+    incompatible with GPLv2 due to its advertisement clause.
+
+The contributed  BDF and PCF  drivers come  with a license  similar to
+that  of the  X Window  System.   It is  compatible to  the above  two
+licenses (see files `src/bdf/README`  and `src/pcf/README`).  The same
+holds   for   the   source    code   files   `src/base/fthash.c`   and
+`include/freetype/internal/fthash.h`; they wer part  of the BDF driver
+in earlier FreeType versions.
+
+The gzip  module uses the  zlib license (see  `src/gzip/zlib.h`) which
+too is compatible to the above two licenses.
+
+The  MD5 checksum  support  (only used  for  debugging in  development
+builds) is in the public domain.

+# SYNOPSIS
+#
+#   AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   This macro compares two version strings. Due to the various number of
+#   minor-version numbers that can exist, and the fact that string
+#   comparisons are not compatible with numeric comparisons, this is not
+#   necessarily trivial to do in a autoconf script. This macro makes doing
+#   these comparisons easy.
+#
+#   The six basic comparisons are available, as well as checking equality
+#   limited to a certain number of minor-version levels.
+#
+#   The operator OP determines what type of comparison to do, and can be one
+#   of:
+#
+#    eq  - equal (test A == B)
+#    ne  - not equal (test A != B)
+#    le  - less than or equal (test A <= B)
+#    ge  - greater than or equal (test A >= B)
+#    lt  - less than (test A < B)
+#    gt  - greater than (test A > B)
+#
+#   Additionally, the eq and ne operator can have a number after it to limit
+#   the test to that number of minor versions.
+#
+#    eq0 - equal up to the length of the shorter version
+#    ne0 - not equal up to the length of the shorter version
+#    eqN - equal up to N sub-version levels
+#    neN - not equal up to N sub-version levels
+#
+#   When the condition is true, shell commands ACTION-IF-TRUE are run,
+#   otherwise shell commands ACTION-IF-FALSE are run. The environment
+#   variable 'ax_compare_version' is always set to either 'true' or 'false'
+#   as well.
+#
+#   Examples:
+#
+#     AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
+#
+#   would both be true.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
+#
+#   would both be false.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
+#
+#   would be true because it is only comparing two minor versions.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
+#
+#   would be true because it is only comparing the lesser number of minor
+#   versions of the two values.
+#
+#   Note: The characters that separate the version numbers do not matter. An
+#   empty string is the same as version 0. OP is evaluated by autoconf, not
+#   configure, so must be a string, not a variable.
+#
+#   The author would like to acknowledge Guido Draheim whose advice about
+#   the m4_case and m4_ifvaln functions make this macro only include the
+#   portions necessary to perform the specific comparison specified by the
+#   OP argument in the final configure script.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
+#   needed for multi-threaded programs (defaults to the value of CC
+#   respectively CXX otherwise). (This is necessary on e.g. AIX to use the
+#   special cc_r/CC_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#   $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#     CXX="$PTHREAD_CXX"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+   *   In certain builds of the library, bzip2 compression recognition is

+   *   This means that if no font driver is capable of handling the raw
+   *   compressed file, the library will try to open a bzip2 compressed
+   *   stream from it and re-open the face with it.
+   *
+   *   The stream implementation is very basic and resets the decompression
+   *   process each time seeking backwards is needed within the stream,
+   *   which significantly undermines the performance.

+ *
+ * @title:
+ *   Error Enumerations
+ *
+ * @abstract:
+ *   How to handle errors and error strings.
+ *
+ * @description:
+ *   The header file `fterrors.h` (which is automatically included by
+ *   `freetype.h` defines the handling of FreeType's enumeration
+ *   constants.  It can also be used to generate error message strings
+ *   with a small macro trick explained below.
+ *
+ *   **Error Formats**
+ *
+ *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+ *   defined in `ftoption.h` in order to make the higher byte indicate the
+ *   module where the error has happened (this is not compatible with
+ *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+ *   for more details.
+ *
+ *   **Error Message Strings**
+ *
+ *   Error definitions are set up with special macros that allow client
+ *   applications to build a table of error message strings.  The strings
+ *   are not included in a normal build of FreeType~2 to save space (most
+ *   client applications do not use them).
+ *
+ *   To do so, you have to define the following macros before including
+ *   this file.
+ *
+ *   ```
+ *     FT_ERROR_START_LIST
+ *   ```
+ *
+ *   This macro is called before anything else to define the start of the
+ *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+ *
+ *   ```
+ *     FT_ERROR_DEF( e, v, s )
+ *   ```
+ *
+ *   This macro is called to define one single error.  'e' is the error
+ *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+ *   numerical value, and 's' is the corresponding error string.
+ *
+ *   ```
+ *     FT_ERROR_END_LIST
+ *   ```
+ *
+ *   This macro ends the list.
+ *
+ *   Additionally, you have to undefine `FTERRORS_H_` before #including
+ *   this file.
+ *
+ *   Here is a simple example.
+ *
+ *   ```
+ *     #undef FTERRORS_H_
+ *     #define FT_ERRORDEF( e, v, s )  { e, s },
+ *     #define FT_ERROR_START_LIST     {
+ *     #define FT_ERROR_END_LIST       { 0, NULL } };
+ *
+ *     const struct
+ *     {
+ *       int          err_code;
+ *       const char*  err_msg;
+ *     } ft_errors[] =
+ *
+ *     #include <freetype/fterrors.h>
+ *   ```
+ *
+ *   An alternative to using an array is a switch statement.
+ *
+ *   ```
+ *     #undef FTERRORS_H_
+ *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+ *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+ *     #define FT_ERROR_END_LIST       }
+ *   ```
+ *
+ *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+ *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.

+   *
+   *   Computing the control box is very fast, while getting the bounding box
+   *   can take much more time as it needs to walk over all segments and arcs
+   *   in the outline.  To get the latter, you can use the 'ftbbox'
+   *   component, which is dedicated to this single task.

+   *
+   * @note:
+   *   Coordinates are relative to the glyph origin, using the y~upwards
+   *   convention.
+   *
+   *   If the glyph has been loaded with @FT_LOAD_NO_SCALE, `bbox_mode` must
+   *   be set to @FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6
+   *   pixel format.  The value @FT_GLYPH_BBOX_SUBPIXELS is another name for
+   *   this constant.
+   *
+   *   If the font is tricky and the glyph has been loaded with
+   *   @FT_LOAD_NO_SCALE, the resulting CBox is meaningless.  To get
+   *   reasonable values for the CBox it is necessary to load the glyph at a
+   *   large ppem value (so that the hinting instructions can properly shift
+   *   and scale the subglyphs), then extracting the CBox, which can be
+   *   eventually converted back to font units.
+   *
+   *   Note that the maximum coordinates are exclusive, which means that one
+   *   can compute the width and height of the glyph image (be it in integer
+   *   or 26.6 pixels) as:
+   *
+   *   ```
+   *     width  = bbox.xMax - bbox.xMin;
+   *     height = bbox.yMax - bbox.yMin;
+   *   ```
+   *
+   *   Note also that for 26.6 coordinates, if `bbox_mode` is set to
+   *   @FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted,
+   *   which corresponds to:
+   *
+   *   ```
+   *     bbox.xMin = FLOOR(bbox.xMin);
+   *     bbox.yMin = FLOOR(bbox.yMin);
+   *     bbox.xMax = CEILING(bbox.xMax);
+   *     bbox.yMax = CEILING(bbox.yMax);
+   *   ```
+   *
+   *   To get the bbox in pixel coordinates, set `bbox_mode` to
+   *   @FT_GLYPH_BBOX_TRUNCATE.

+   * @title:
+   *   Subpixel Rendering
+   *
+   * @abstract:
+   *   API to control subpixel rendering.
+   *
+   * @description:
+   *   FreeType provides two alternative subpixel rendering technologies.
+   *   Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
+   *   `ftoption.h` file, this enables ClearType-style rendering.
+   *   Otherwise, Harmony LCD rendering is enabled.  These technologies are
+   *   controlled differently and API described below, although always
+   *   available, performs its function when appropriate method is enabled
+   *   and does nothing otherwise.
+   *
+   *   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.  Using the
+   *   subpixel coverages unfiltered can create severe color fringes
+   *   especially when rendering thin features.  Indeed, to produce
+   *   black-on-white text, the nearby color subpixels must be dimmed
+   *   evenly.  Therefore, an equalizing 5-tap FIR filter should be applied
+   *   to subpixel coverages regardless of pixel boundaries and should have
+   *   these properties:
+   *
+   *   1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
+   *      any shifts in appearance.
+   *
+   *   2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
+   *      fringes by distributing the computed coverage for one subpixel to
+   *      all subpixels equally.
+   *
+   *   3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
+   *      overall brightness.
+   *
+   *   Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
+   *   forgiving of non-ideal gamma curves of a screen (and viewing angles),
+   *   beveled filters are fuzzier but more tolerant.
+   *
+   *   Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
+   *   API to specify a low-pass filter, which is then applied to
+   *   subpixel-rendered bitmaps generated through @FT_Render_Glyph.
+   *
+   *   Harmony LCD rendering is suitable to panels with any regular subpixel
+   *   structure, not just monitors with 3 color striped subpixels, as long
+   *   as the color subpixels have fixed positions relative to the pixel
+   *   center.  In this case, each color channel can be rendered separately
+   *   after shifting the outline opposite to the subpixel shift so that the
+   *   coverage maps are aligned.  This method is immune to color fringes
+   *   because the shifts do not change integral coverage.
+   *
+   *   The subpixel geometry must be specified by xy-coordinates for each
+   *   subpixel. By convention they may come in the RGB order: {{-1/3, 0},
+   *   {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
+   *   {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
+   *
+   *   Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
+   *   If one follows the RGB order convention, the same order applies to the
+   *   resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps.  Note,
+   *   however, that the coordinate frame for the latter must be rotated
+   *   clockwise.  Harmony with default LCD geometry is equivalent to
+   *   ClearType with light filter.
+   *
+   *   As a result of ClearType filtering or Harmony shifts, the resulting
+   *   dimensions of LCD bitmaps can be slightly wider or taller than the
+   *   dimensions the original outline with regard to the pixel grid.
+   *   For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
+   *   the left, and 2~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.
+   *
+   *   The ClearType and Harmony rendering is applicable to glyph bitmaps
+   *   rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
+   *   @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
+   *   is specified.  This API does not control @FT_Outline_Render and
+   *   @FT_Outline_Get_Bitmap.
+   *
+   *   The described algorithms can completely remove color artefacts when
+   *   combined with gamma-corrected alpha blending in linear space.  Each of
+   *   the 3~alpha values (subpixels) must by 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.

+   * @description:
+   *   The following types and functions are used to manage Multiple Master
+   *   fonts, i.e., the selection of specific design instances by setting
+   *   design axis coordinates.
+   *
+   *   Besides Adobe MM fonts, the interface supports Apple's TrueType GX and
+   *   OpenType variation fonts.  Some of the routines only work with Adobe
+   *   MM fonts, others will work with all three types.  They are similar
+   *   enough that a consistent interface makes sense.
+   *
+   *   For Adobe MM fonts, macro @FT_IS_SFNT returns false.  For GX and
+   *   OpenType variation fonts, it returns true.

+   *
+   * This file is used to define the FreeType module error codes.
+   *
+   * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
+   * set, the lower byte of an error value identifies the error code as
+   * usual.  In addition, the higher byte identifies the module.  For
+   * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
+   * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
+   * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
+   *
+   * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
+   * including the high byte.
+   *
+   * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
+   * error value is set to zero.
+   *
+   * To hide the various `XXX_Err_` prefixes in the source code, FreeType
+   * provides some macros in `fttypes.h`.
+   *
+   *   FT_ERR( err )
+   *
+   *     Add current error module prefix (as defined with the `FT_ERR_PREFIX`
+   *     macro) to `err`.  For example, in the BDF module the line
+   *
+   *     ```
+   *       error = FT_ERR( Invalid_Outline );
+   *     ```
+   *
+   *     expands to
+   *
+   *     ```
+   *       error = BDF_Err_Invalid_Outline;
+   *     ```
+   *
+   *     For simplicity, you can always use `FT_Err_Ok` directly instead of
+   *     `FT_ERR( Ok )`.
+   *
+   *   FT_ERR_EQ( errcode, err )
+   *   FT_ERR_NEQ( errcode, err )
+   *
+   *     Compare error code `errcode` with the error `err` for equality and
+   *     inequality, respectively.  Example:
+   *
+   *     ```
+   *       if ( FT_ERR_EQ( error, Invalid_Outline ) )
+   *         ...
+   *     ```
+   *
+   *     Using this macro you don't have to think about error prefixes.  Of
+   *     course, if module errors are not active, the above example is the
+   *     same as
+   *
+   *     ```
+   *       if ( error == FT_Err_Invalid_Outline )
+   *         ...
+   *     ```
+   *
+   *   FT_ERROR_BASE( errcode )
+   *   FT_ERROR_MODULE( errcode )
+   *
+   *     Get base error and module error code, respectively.
+   *
+   * It can also be used to create a module error message table easily with
+   * something like
+   *
+   * ```
+   *   #undef FTMODERR_H_
+   *   #define FT_MODERRDEF( e, v, s )  { FT_Mod_Err_ ## e, s },

+   *     querying for information about the character set of the font that is

+   *     value (of the related Windows API) simply denotes failure.

+   *   FT_WinFNT_ID_OEM ::
+   *     From Michael Poettgen <michael@poettgen.de>:
+   *
+   *     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://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers
+   *     ,
+   *
+   *     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.

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

+   *
+   * @description:
+   *   The font driver class.  This structure mostly contains pointers to
+   *   driver methods.
+   *
+   * @fields:
+   *   root ::
+   *     The parent module.
+   *
+   *   face_object_size ::
+   *     The size of a face object in bytes.
+   *
+   *   size_object_size ::
+   *     The size of a size object in bytes.
+   *
+   *   slot_object_size ::
+   *     The size of a glyph object in bytes.
+   *
+   *   init_face ::
+   *     The format-specific face constructor.
+   *
+   *   done_face ::
+   *     The format-specific face destructor.
+   *
+   *   init_size ::
+   *     The format-specific size constructor.
+   *
+   *   done_size ::
+   *     The format-specific size destructor.
+   *
+   *   init_slot ::
+   *     The format-specific slot constructor.
+   *
+   *   done_slot ::
+   *     The format-specific slot destructor.
+   *
+   *
+   *   load_glyph ::
+   *     A function handle to load a glyph to a slot.  This field is
+   *     mandatory!
+   *
+   *   get_kerning ::
+   *     A function handle to return the unscaled kerning for a given pair of
+   *     glyphs.  Can be set to 0 if the format doesn't support kerning.
+   *
+   *   attach_file ::
+   *     This function handle is used to read additional data for a face from
+   *     another file/stream.  For example, this can be used to add data from
+   *     AFM or PFM files on a Type 1 face, or a CIDMap on a CID-keyed face.
+   *
+   *   get_advances ::
+   *     A function handle used to return advance widths of 'count' glyphs
+   *     (in font units), starting at 'first'.  The 'vertical' flag must be
+   *     set to get vertical advance heights.  The 'advances' buffer is
+   *     caller-allocated.  The idea of this function is to be able to
+   *     perform device-independent text layout without loading a single
+   *     glyph image.
+   *
+   *   request_size ::
+   *     A handle to a function used to request the new character size.  Can
+   *     be set to 0 if the scaling done in the base layer suffices.
+   *
+   *   select_size ::
+   *     A handle to a function used to select a new fixed size.  It is used
+   *     only if @FT_FACE_FLAG_FIXED_SIZES is set.  Can be set to 0 if the
+   *     scaling done in the base layer suffices.
+   * @note:
+   *   Most function pointers, with the exception of `load_glyph`, can be set
+   *   to 0 to indicate a default behaviour.
