TeXLive still supports Solaris 5.10, where the system's `grep` doesn't
accept the `-E` option. We thus introduce an `EGREP` variable that is set
to either `grep -E` or `-egrep`.
This is unnecessary for predefined standard and expert encodings.
Even for custom encodings the arrays might be already zeroed when
CFF_FontRec is created but we keep it just in case.
Also short-circuit on `offset` to avoid checking `count` a second time when
`ft_ansi_stream_io` is used for reading.
Per ISO/IEC 9899:
If an argument to a function has an invalid value (such as a value outside
the domain of the function, or a pointer outside the address space of the
program, or a null pointer, or apointer to non-modifiable storage when the
corresponding parameter is not const-qualified) or a type (after
promotion) not expected by a function with variable number of arguments,
the behavior is undefined. If a function argument is described as being
an array, the pointer actually passed to the function shall have a value
such that all address computations and accesses to objects (that would be
valid if the pointer did point to the first element of such an array) are
in fact valid.
Per IEEE Std 1003.1:
size_t fread(void *restrict ptr, size_t size, size_t nitems,
FILE *restrict stream);
The `fread` function shall read into the array pointed to by `ptr` up to
`nitems` elements whose size is specified by `size` in bytes, from the
stream pointed to by `stream`.
Since the first argument to `fread` is described as being an array, its
behavior is undefined when that argument is a null pointer.
Per the documentation on `ft_ansi_stream_io`:
If `count' is zero (this is, the function is used for seeking), a non-zero
return value indicates an error.
Thus the intent is clear, and the call to `fread` can be skipped, avoiding
undefined behaviour.
* src/base/ftoutln.c (FT_Outline_Reverse, FT_Outline_EmboldenXY,
FT_Outline_Get_Orientation): Set the first and last indexes together.
(FT_Outline_Decompose): Ditto and check them more stringently.
* src/smooth/ftgrays.c (FT_Outline_Decompose)[STANDALONE_]: Ditto.
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.
A cubic contour has to always start from an on-point. Therefore, we
should not swap the first with the last point, which might be off, and
obtain an invalid contour. This does not matter for conic contours.
If anything, it also saves one swap there. Fixes#1207.
The design coordinates for MM fonts were not rounded. For example,
`FT_Get_Var_Design_Coordinates` returned values with fractional part.
* src/type1/t1load.c (mm_axis_unmap): Refactor with rounding.
* include/freetype/ftmm.h (FT_Var_Axis, FT_Set_Var_Design_Coordinates,
FT_Get_Var_Design_Coordinates): Reword documentation.

* builds/unix/configure.raw (version_info): Set to 25:0:19.
* CMakeLists.txt (VERSION_MINOR): Set to 13.
(VERSION_PATCH): Set to 0.
* src/autofit/ft-hb.c: Decorate with `FT_LOCAL_DEF`.
Add ANSI boilerplate code for otherwise empty file.
* src/autofit/ft-hb.h: Include `compiler-macros.h` and `freetype.h`.
Use `FT_BEGIN_HEADER` and `FT_END_HEADER`.
Decorate with `FT_LOCAL`.
* src/autofit/rules.mk (AUTOF_DRV_SRC): Add `ft-hb.c`.
Modern compilers get more insistent on that...
* include/freetype/internal/compiler-macros.h (FALL_THROUGH): Define.
* src/*: Use it instead of `/* fall through */` comments.
Otherwise we get zillions of clang 15 warnings.
* src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
src/base/ftobjs.c, src/base/ftoutln.c, src/cff/cffparse.c,
src/raster/ftraster.c, src/sfnt/pngshim.c, src/truetype/ttgload.c,
src/truetype/ttgxvar.c, src/truetype/ttobjs.c, src/type1/t1gload.c: Use
`double` cast in debugging and tracing macros.
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_`.
* src/sdf/ftsdfcommon.h (FT_16D16, FT_26D6): Use 32-bit integers
instead of `FT_Fixed` for internal data types. `FT_Fixed` i.e.
`signed long` is 64-bit on some architectures.
The ascender and descender are optional in the AFM specifications.
They could be omitted or even set to zero, e.g., in the current release
of URW++ base 35 fonts.
In `open_face_from_buffer` it is possible that a driver is requested but
FreeType was built without the requested module. Return an error in this
case to indicate that the request could not be satisfied, rather than trying
all existing driver modules.
* src/base/ftobjs.c (open_face_from_buffer): Return `FT_Err_Missing_Module`
if a driver is specified but not found.
The documentation for `FT_StreamRec::memory` states that it 'shouldn't be
touched by stream implementations'. This is true even for internal
implementations of the 'close' callback, since it is not guaranteed that
`memory` will even be set when the 'close' callback occurs.
* src/base/ftobjs.c (new_memory_stream): stash current `memory` in
`stream->descriptor`.
(memory_stream_close): Use it.
