Remove Infinality as an option before its complete extraction.
* include/freetype/ftoption.h: Remove the Infinality option.
* devel/ftoption.h: Ditto.
* include/freetype/ftdriver.h (TT_INTERPRETER_VERSION_38): Is 40 now.
This is mandated by the C99 standard, and clang 15 produces zillions of
warnings otherwise.
* devel/ftoption.h, include/freetype/config/ftoption.h,
include/freetype/internal/ftmemory.h, src/autofit/afhints.h,
src/autofit/afmodule.c, src/autofit/aftypes.h, src/base/ftadvanc.c,
src/base/ftdbgmem.c, src/base/ftstream.c, src/bdf/bdflib.c,
src/truetype/ttinterp.c: Replace identifiers of the form `_foo` with `foo_`.
This gives users a possibility to deactivate new features not (yet) in the
OpenType standard.
* include/freetype/config/ftoption.h, devel/ftoption.h
(TT_CONFIG_OPTION_NO_BORING_EXPANSION): New macro.
* src/truetype/ttgxvar.c (ft_var_load_avar): Use it to disable 'avar'
version 2.0 support.
* include/freetype/config/ftheader.h (FT_OTSVG_H): New macro.
* include/freetype/freetype.h (FT_FACE_FLAG_SVG, FT_HAS_SVG): New macros.
(FT_LOAD_SVG_ONLY): New internal macro.
* include/freetype/ftimage.h (FT_Glyph_Format): New enumeration value
`FT_GLYPH_FORMAT_SVG`.
* include/freetype/internal/ftobjs.h (FT_GLYPH_OWN_GZIP_SVG): New macro.
* include/freetype/internal/fttrace.h: Add `ttsvg` for `ttsvg.c`.
* include/freetype/internal/sfnt.h(load_svg, free_svg, load_svg_doc): New
functions.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add `svg` for
the SVG table.
* include/freetype/otsvg.h (FT_SVG_DocumentRec): New structure to hold the
SVG document and other necessary information of an OT-SVG glyph in a glyph
slot.
* include/freetype/tttags.h (TTAG_SVG): New macro.
* src/base/ftobjs.c: Include `otsvg.h`.
(ft_glyphslot_init): Allocate `FT_SVG_DocumentRec` in `slot->other`
if the SVG table exists.
(ft_glyphslot_clear): Free it upon clean-up if it is a GZIP compressed
glyph.
(ft_glyphslot_done): Free the document data if it is a GZIP compressed
glyph.
(FT_Load_Glyph): Don't auto-hint SVG documents.
* src/cache/ftcbasic.c (ftc_basic_family_load_glyph): Add support for
FT_GLYPH_FORMAT_SVG.

* src/sfnt/sfobjs.c (sfnt_load_face, sfnt_done_face): Add code to load and
free data of the the SVG table.
* src/sfnt/ttsvg.c: New file, implementing `tt_face_load_svg`,
`tt_face_free_svg` and `tt_face_load_svg_doc`.
* src/sfnt/ttsvg.h: Declarations of the SVG functions in
`ttsvg.c`.
This flag is going to be used to conditionally compile support for OT-SVG
glyphs. FreeType will do the parsing and rely on external hooks for
rendering of OT-SVG glyphs.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_SVG): New flag.
* include/freetype/config/integer-types.h: Make sure `long long` is
used then available.
* include/freetype/internal/ftcalc.h (FT_MSB): Add Watcom C/C++ pragma.
We really have to use double casts to avoid issues with C's and C++'s
signedness propagation rules in implicit casts.

* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): Modify macro to take two arguments.
Update all callers.
(FT_STATIC_BYTE_CAST): New macro.
* include/freetype/freetype.h (FT_ENC_TAG): Use `FT_STATIC_BYTE_CAST`.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG): Ditto.
Use `FT_Tag` for casting.
* src/ftraster/ftmisc.h (FT_MAKE_TAG): Removed, no longer needed.
(FT_STATIC_BYTE_CAST): New macro.
* src/smooth/ftgrays.c (FT_STATIC_CAST): Replace with...
(FT_STATIC_BYTE_CAST): ... this.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.
* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,
FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`.
Correctly handle negative 'signed char' input.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto.
* include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use
`FT_REINTERPRET_CAST`.
* src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro.
[!STANDALONE]: Include `FT_CONFIG_CONFIG_H`.
Fixes#1116.
MSVC, for example, used `long long` even without full C99 support.
* include/freetype/config/ftstdlib.h: Check if `long long` limits are
defined in <limits.h>.
* include/freetype/config/integer-types.h: Check `long long` size and
use it to typedef FT_Int64.
This feature was always experimental, and probably nevery worked
properly. This patch completely removes it from the source code,
except for a documentation block describing it for historical
purpose.
* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are
building against supports the 'COLR' v1 API. This is intended to be
a temporary solution until 'COLR' v1 support is released in a
FreeType version and such a check can be made by using the version
number instead.
* include/freetype/config/ftmodule.h: Add both the 'sfd' and 'bsfd'
renderers to the list of modules.
* CMakeLists.txt (BASE_SRCS): Add 'sdf' single-object module.
Other compilers are unchanged.
* builds/compiler/gcc-dev.mk, builds/compiler/gcc.mk (ANSIFLAGS):
s/-ansi/-std=c99/.
* builds/freetype.mk (FT_CFLAGS): Remove `-std=c99`.
* builds/unix/configure.raw: Handle C99.
Remove no longer needed test for gcc 4.6 and earlier.
* autogen.sh (copy_submodule_files): New script to copy all the
necessary source and include files from `submodules/dlg` to
`src/dlg`.
* src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables
the build of 'dlg' if the `FT_LOGGING` macro is defined.
* src/dlg/rules.mk: New sub-Makefile.
* builds/freetype.mk (DLG_DIR): New variable to include the
header files of the 'dlg' library.
(INCLUDES): Add `DLG_DIR`.
(FT_CFLAGS): Add `-std=c99' flag.
Include `src/dlg/rules.mk` file to build 'dlg' library.
(OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`.
* builds/toplevel.mk: For builds directly from the git repository
we need to copy files from `submodule/dlg` to `src/dlg`.
* include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING):
New macro to enable or disable the logging facility in FreeType.
The following builds were still failing due to previous changes:
make multi
make multi CC="c++"
make CC="c++"
This patch fixes the issues, which were missing includes to get the
right macro definitions in multi-build mode.
Also, `FT_UNUSED' is actually used by third-party code, so move it
back to `public-macros.h' to avoid breaking it.
* include/freetype/config/public-macros.h (FT_EXPORT): Remove
special definition for C++.
(FT_UNUSED): Define here instead of...
* include/freetype/config/compiler-macros.h: ... here.
(FT_FUNCTION_DECLARATION): Remove special definition for C++.
(FT_LOCAL_ARRAY_DEF): Fix definition.
* src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,
src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.
The following builds were failing due to previous changes:
make multi
make multi CC="c++"
* include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'.
* include/freetype/config/ftheader.h (FT_BEGIN_HEADER,
FT_END_HEADER): Protect against redefinition.
* src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h,
src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h,
src/sfnt/woff2tags.h: Include `compiler-macros.h'.
* src/sfnt/woff2tags.c: Include `woff2tags.h'.
* include/freetype/config/public-macros.h
(FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as
public (and thus exportable).
(FT_EXPORT): Use it.
* include/freetype/config/compiler-macros.h
(FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as
internal to the library (and thus hidden). Note that on ELF
systems, all internal functions have hidden visibility, which avoids
the need to enforce this when invoking the compiler (e.g., with an
option like `-fvisibility=hidden').
(FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros
to deal with C and C++ linkage issues at the same time.
(FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF,
FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK,
FT_BASE_CALLBACK_DEF): Redefined using new macros.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions
required by the FreeType API headers to...
* include/freetype/config/public-macros.h: ...this new file.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions used
by the library but not to be exposed to clients to...
* include/freetype/config/compiler-macros.h: ...this new file.
* include/freetype/internal/*.h, src/raster/ftraster.h: Include
`compiler-macros.h' where needed.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off mac-specific stuff
to...
* include/freetype/config/mac-support.h: ...this new file.
* CMakeLists.txt, builds/unix/configure.raw: Remove `/undef ->
#undef' string replacement; the affected code is no longer part of
the `ftconfig.h' template.
Refactor some of the `ftconfig.h' headers and template to move the
definition of the FreeType integer types (e.g., `FT_Int16') to a
common header file `freetype/config/integer-types.h'.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off integer type
definition stuff to...
* include/freetype/config/integer-types.h: ...this new file.
* builds/unix/ftconfig.h.in: Control the definition of
`FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro
`FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto
detection happens in `integer-types.h' as usual based on `INTXX_MAX'
values. Otherwise the autoconf-detected values are used.
* builds/unix/configure.raw (CPPFLAGS): Don't include path to
`config' directory. Instead, ...
(FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
These have not been used in a very, very long time, so better remove
them. A corresponding patch will be submitted to the
`freetype2-demos' repository.
* src/Jamfile, src/*/Jamfile, Jamrules: Delete.
The LCD modules were never truly independent. They mostly served as
a way to disable patented LCD rendering, which is no longer necessary.
The `smooth' module now handles LCD modes as well.
* src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class.
ft_smooth_lcdv_renderer_class): Deleted.
(ft_render_smooth): Reworked from `ft_render_smooth_generic'.
* src/smooth/ftsmooth.h: Remove dedicated LCD classes.
* src/smooth/module.mk: Remove dedicated LCD modules.
* include/freetype/config/ftmodule.h: Ditto.
* builds/amiga/include/config/ftmodule.h: Ditto.
* include/freetype/ftmodapi.h: Do not mention LCD modules.
The libs which cmake controls are commented out at
include/freetype/config/ftoption.h
and cmake un-comment each enabled library, but the brotli option was
not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained
defined even if brotli was missing/disabled/etc.
Comment it such that cmake can control it, which means leaving it
undefined if brotli is missing.
* include/freetype/config/ftoption.h: Fix typo.
Brotli is required for decompressing WOFF2 font directory streams.
The library is thus being added as an optional dependency for
FreeType.
* builds/unix/configure.raw: Add checks for `libbrotlidec'.
(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_BROTLI): New macro.
