* ```
*
* These macros were introduced to overcome the infamous 8.3~naming rule

*
* @section:
* error_enumerations
*
* @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.
*/
/* */
/* In previous FreeType versions we used `__FTERRORS_H__`. However, */
/* using two successive underscores in a non-system symbol name */
/* violates the C (and C++) standard, so it was changed to the */
/* current form. In spite of this, we have to make */
/* */
/* ``` */
/* #undefine __FTERRORS_H__ */

*
* @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

* @section:
* lcd_rendering
*
* @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.

/**************************************************************************
*
* 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 },
* #define FT_MODERR_START_LIST {
* #define FT_MODERR_END_LIST { 0, 0 } };
*
* const struct
* {
* int mod_err_offset;
* const char* mod_err_msg

*
* 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.

* 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.
