Update freetype to 2.12.1

Browse Source 
ftdebug.c files are new, adapted the import script to copy the source
file for Windows as well.

Replaced the CMakeLists.txt content that was imported from the .pro file
with the respective variables and logic from the freetype CMakeLists.txt
file, which should make it easier to maintain this next time.

Fixes: QTBUG-105032

CHANGES BETWEEN 2.10.3 and 2.10.4
CHANGES BETWEEN 2.12.0 and 2.12.1
I. IMPORTANT BUG FIXES
- Loading CFF fonts sometimes made FreeType crash (bug introduced in
version 2.12.0)
- Loading a fully hinted TrueType glyph a second time (without
caching) sometimes yielded different rendering results if TrueType
hinting was active (bug introduced in version 2.12.0).
- The generation of the pkg-config file `freetype2.pc` was broken if
the build was done with cmake (bug introduced in version 2.12.0).
II. MISCELLANEOUS
- New option `--with-librsvg` for the `configure` script for better
FreeType demo support.
- The meson build no longer enforces both static and dynamic
versions of the library by default.
- The internal zlib library was updated to version 1.2.12. Note,
however, that FreeType is *not* affected by CVE-2018-25032 since
it only does decompression.
======================================================================
CHANGES BETWEEN 2.11.1 and 2.12.0
I. IMPORTANT CHANGES
- FreeType now handles OT-SVG fonts, to be controlled with
`FT_CONFIG_OPTION_SVG` configuration macro. By default, it can
only load the 'SVG ' table of an OpenType font. However, by using
the `svg-hooks` property of the new 'ot-svg' module it is possible
to register an external SVG rendering engine. The FreeType demo
programs have been set up to use 'librsvg' as the rendering
library.
This work was Moazin Khatti's GSoC 2019 project.
II. MISCELLANEOUS
- The handling of fonts with an 'sbix' table has been improved.
- Corrected bitmap offsets.
- A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes
FreeType ignore an 'sbix' table in a font, allowing applications
to access the font's outline glyphs.
- `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together
with their corresponding preprocessor macros `FT_HAS_SBIX` and
`FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables
as described in the OpenType specification.
- The internal 'zlib' code has been updated to be in sync with the
current 'zlib' version (1.2.11).
- The previously internal load flag `FT_LOAD_SBITS_ONLY` is now
public.
- Some minor improvements of the building systems, in particular
handling of the 'zlib' library (internal vs. external).
- Support for non-desktop Universal Windows Platform.
- Various other minor bug and documentation fixes.
- The `ftdump` demo program shows more information for Type1 fonts
if option `-n` is given.
- `ftgrid` can now display embedded bitmap strikes.
======================================================================
CHANGES BETWEEN 2.11.0 and 2.11.1
I. IMPORTANT CHANGES
- Some fields in the `CID_FaceDictRec`, `CID_FaceInfoRec`, and
`FT_Data` structures have been changed from signed to unsigned
type, which better reflects the actual usage. It is also an
additional means to protect against malformed input.
II. MISCELLANEOUS
- Cmake support has been further improved. To do that various
backward-incompatible changes were necessary; please see file
`CMakeLists.txt` for more details.
- Since version 2.11.0, a C99 compiler is necessary to compile
FreeType.
- The experimental 'COLR' v1 API has been updated to the latest
OpenType standard 1.9.
- The `apinames` tool got a new option `-wV` to output an OpenVMS
Linker Option File.
- VMS support was updated.
- MS Visual Studio support was added to build the demo programs.
======================================================================
CHANGES BETWEEN 2.10.4 and 2.11.0
I. IMPORTANT CHANGES
- A new rendering module has been added to create 8-bit Signed
Distance Field (SDF) bitmaps for both outline and bitmap glyphs.
The new rendering mode is called `FT_RENDER_MODE_SDF`, the pixel
mode is `FT_PIXEL_MODE_GRAY8`, and the corresponding raster flag
is `FT_RASTER_FLAG_SDF`.
This work was Anuj Verma's GSoC 2020 project.
- A new, experimental API is now available for surfacing properties
of 'COLR' v1 color fonts (as the name says, this is an extension
to the 'COLR' table for outline color fonts using the SFNT
container format). 'COLR' v1 fonts are a recently proposed
addition to OFF and OpenType; specification work currently happens
in
https://github.com/googlefonts/colr-gradients-spec/
'COLR' v1 is expected to be merged to OpenType; the ISO
standardisation process for adding 'COLR' v1 as an amendment to
OFF is underway.
Functions similar to the already existing 'COLR' API have been
added to access the corresponding data.
FT_Get_Color_Glyph_Paint
Retrieve the root paint for a given glyph ID.
FT_Get_Paint_Layers
Access the layers of a `PaintColrLayers` table.
FT_Get_Colorline_Stops
Retrieve the 'color stops' on a color line. As an input, a
color stop iterator gets used, which in turn is retrieved from
a paint.
FT_Get_Paint
Dereference an `FT_OpaquePaint` object and retrieve the
corresponding `FT_COLR_Paint` object, which contains details
on how to draw the respective 'COLR' v1 `Paint` table.
II. MISCELLANEOUS
- FreeType has moved its infrastructure to
https://gitlab.freedesktop.org/freetype
A side effect is that the git repositories are now called
`freetype.git` and `freetype-demos.git`, which by default expand
to the directories `freetype` and `freetype-demos`, respectively.
The documentation has been updated accordingly.
FreeType's Savannah repositories will stay; they are now mirrors
of the 'freedesktop.org' repositories.
- A new function `FT_Get_Transform` returns the values set by
`FT_Set_Transform`.
- A new configuration macro `FT_DEBUG_LOGGING` is available. It
provides extended debugging capabilities for FreeType, for example

This work was Priyesh Kumar's GSoC 2020 project.
- The legacy Type 1 and CFF engines are further demoted due to lack
of CFF2 charstring support. You now need to use `FT_Property_Set`
to enable them besides the `T1_CONFIG_OPTION_OLD_ENGINE` and
`CFF_CONFIG_OPTION_OLD_ENGINE` options, respectively.
- The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the
auto-hinter has been removed.
- The smooth rasterizer performance has been improved by >10%. Note
that due to necessary code changes there might be very subtle
differences in rendering. They are not visible by the eye,
however.
- PCF bitmap fonts compressed with LZW (these are usually files with
the extension `.pcf.Z`) are now handled correctly.
- Improved Meson build files, including support to build the
FreeType demo programs.
- A new demo program `ftsdf` is available to display Signed Distance
Fields of glyphs.
- The `ftlint` demo program has been extended to do more testing of
its input. In particular, it can display horizontal and vertical
acutances for quality assessment, together with computing MD5
checksums of rendered glyphs.
[The acutance measures how sharply the pixel coverage changes at
glyph edges. For monochrome bitmaps, it is always 2.0 in either
X or Y direction. For anti-aliased bitmaps, it depends on the
hinting and the shape of a glyph and might approach or even reach
value 2.0 for glyphs like 'I', 'L', '+', '-', or '=', while it
might be lower for glyphs like 'O', 'S', or 'W'.]
- The `ttdebug` demo program didn't show changed point coordinates
(bug introduced in version 2.10.3).
- It is now possible to adjust the axis increment for variable fonts
in the `ftmulti` demo program.
- It is now possible to change the hinting engine in the `ftstring`
demo program.
- The graphical demo programs work better now in native color depth
on win32 and x11.

FT_DEBUG_LOGGING
#define this macro for enhanced logging support; it automatically
sets `FT_DEBUG_LEVEL_TRACE' and `FT_DEBUG_LEVEL_ERROR'.
If defined, `FT_TRACE' and `FT_ERROR' can send tracing and
debugging messages to a file. The location of the log file has to
be set with the `FT_LOGGING_FILE' environment variable (more on
this later).
The main enhancements are the possibility of logging the time and

IV. Additional Capabilities with `FT_DEBUG_LOGGING'
---------------------------------------------------
If `FT_DEBUG_LOGGING' is defined, four APIs are available to provide
additional debugging support. Use
#include <freetype/ftlogging.h>
to access them.
FT_Trace_Set_Level( const char* level )
By default, FreeType uses the tracing levels set in the
`FT2_DEBUG' environment variable. Use this function to override
the value with `level'. Use value `NULL' to disable tracing.
FT_Trace_Set_Default_Level():
Reset the tracing levels to the default value, i.e., the value of
the `FT2_DEBUG' environment variable or no tracing if not set.
FT_Set_Log_Handler( ft_custom_log_handler handler ):
Use `handler' as a custom handler for formatting tracing and error
messages. The `ft_custom_log_handler' typedef has the following
prototype.
void
(*ft_custom_log_handler)( const char* ft_component,
const char* fmt,
va_list args );
`ft_component' is the current component like `ttload', `fmt' is the
first argument of `FT_TRACE' or `FT_ERROR', and `args' holds the
remaining arguments.

The FreeType 2 font engine is copyrighted work and cannot be used

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 `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 `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
file src/bdf/README and src/pcf/README). The same holds for the files
`fthash.c' and `fthash.h'; their code was 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)

*
* @description:
* FreeType is a library that provides access to glyphs in font files. It
* scales the glyph images and their metrics to a requested size, and it
* rasterizes the glyph images to produce pixel or subpixel alpha coverage
* bitmaps.
*
* Note that FreeType is _not_ a text layout engine. You have to use
* higher-level libraries like HarfBuzz, Pango, or ICU for that.
*
* Note also that FreeType does _not_ perform alpha blending or
* compositing the resulting bitmaps or pixmaps by itself. Use your
* favourite graphics library (for example, Cairo or Skia) to further
* process FreeType's output.

* FT_RENDER_MODE_SDF ::
* This mode corresponds to 8-bit, single-channel signed distance field
* (SDF) bitmaps. Each pixel in the SDF grid is the value from the
* pixel's position to the nearest glyph's outline. The distances are
* calculated from the center of the pixel and are positive if they are
* filled by the outline (i.e., inside the outline) and negative
* otherwise. Check the note below on how to convert the output values

*
* @note:
* The selected render mode only affects vector glyphs of a font.
* Embedded bitmaps often have a different pixel mode like
* @FT_PIXEL_MODE_MONO. You can use @FT_Bitmap_Convert to transform them
* into 8-bit pixmaps.
*
* For @FT_RENDER_MODE_SDF the output bitmap buffer contains normalized
* distances that are packed into unsigned 8-bit values. To get pixel
* values in floating point representation use the following pseudo-C
* code for the conversion.
*
* ```
* // Load glyph and render using FT_RENDER_MODE_SDF,
* // then use the output buffer as follows.
*

* FT_Byte buffer = glyph->bitmap->buffer;

* sd = ( sd / 128.0f ) * spread;
*
* // Store `sd` in a buffer or use as required.
* }
*
* ```
*
* FreeType has two rasterizers for generating SDF, namely:
*
* 1. `sdf` for generating SDF directly from glyph's outline, and
*
* 2. `bsdf` for generating SDF from rasterized bitmaps.
*
* Depending on the glyph type (i.e., outline or bitmap), one of the two
* rasterizers is chosen at runtime and used for generating SDFs. To
* force the use of `bsdf` you should render the glyph with any of the
* FreeType's other rendering modes (e.g., `FT_RENDER_MODE_NORMAL`) and
* then re-render with `FT_RENDER_MODE_SDF`.
*
* There are some issues with stability and possible failures of the SDF
* renderers (specifically `sdf`).
*
* 1. The `sdf` rasterizer is sensitive to really small features (e.g.,
* sharp turns that are less than 1~pixel) and imperfections in the
* glyph's outline, causing artifacts in the final output.
*
* 2. The `sdf` rasterizer has limited support for handling intersecting
* contours and *cannot* handle self-intersecting contours whatsoever.
* Self-intersection happens when a single connected contour intersect
* itself at some point; having these in your font definitely pose a
* problem to the rasterizer and cause artifacts, too.
*
* 3. Generating SDF for really small glyphs may result in undesirable
* output; the pixel grid (which stores distance information) becomes
* too coarse.
*
* 4. Since the output buffer is normalized, precision at smaller spreads
* is greater than precision at larger spread values because the
* output range of [0..255] gets mapped to a smaller SDF range. A
* spread of~2 should be sufficient in most cases.
*
* Points (1) and (2) can be avoided by using the `bsdf` rasterizer,
* which is more stable than the `sdf` rasterizer in general.

* If FreeType gets compiled with option `AF_CONFIG_OPTION_USE_WARPER` to

*
* By default, warping is off.
*
* @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

* This section contains technical definitions.
* A raster or a rasterizer is a scan converter in charge of producing a
* pixel coverage bitmap that can be used as an alpha channel when
* compositing a glyph with a background. FreeType comes with two
* rasterizers: bilevel `raster1` and anti-aliased `smooth` are two
* separate modules. They are usually called from the high-level
* @FT_Load_Glyph or @FT_Render_Glyph functions and produce the entire
* coverage bitmap at once, while staying largely invisible to users.
*
* Instead of working with complete coverage bitmaps, it is also possible
* to intercept consecutive pixel runs on the same scanline with the same
* coverage, called _spans_, and process them individually. Only the
* `smooth` rasterizer permits this when calling @FT_Outline_Render with
* @FT_Raster_Params as described below.
