* CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer.
The issue #1059 reports the difficulty to support both of
CMake 2.x and newer one by single CMakeLists.txt without
the inflation of cmake_policy() workarounds.
For better maintainability, the support of CMake 2.x is
dropped.
Before the change, the hinting engine frequently confused horizontal
stem and serif hints making some stems too thin and some serifs too
thick. The value was tuned using serif fonts from the URW+ base 35
collection.
* src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/.
Since Type42 fonts don't have a 'Private' dictionary, the return value
should be `FT_Err_Invalid_Argument`.
* src/type42/t42drivr.c (t42_ps_get_font_private): Removed.
(t42_service_ps_info): Updated.
In PS hinter, memory allocations persist until the module is done.
Therefore, we have to clear reused masks.
* src/pshinter/pshrec.c (ps_mask_table_alloc): Clear reused mask.
We forgot to update the number of bits when merging a larger mask
into a smaller one. This fix might have rendering effects.
* src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number
of bits from a larger mask. There is no need to zero unused bits,
already zeroed during allocation.
(ps_mask_clear_bit): Removed.
(ps_mask_ensure): Minor.
* src/pshinter/pshrec.c (ps_hint_table_ensure): Remove redundant size
check; avoid array zeroing because it is fully initialized when used.
(ps_hint_table_alloc): Fix off-by-one comparison and remove another
zeroing of the array elements.
* CMakeLists.txt (CMAKE_OSX_ARCHITECTURES): Update value to fix the building
of a framework on MacOS.
* builds/mac/freetype-Info.plist (CFBundleExecutable): Make identifier
lowercase only.
Fixes#1127.
The old impleemntation was not using `FT_REALLOC`, buing too careful
with the offset rebasing. It shoudl be safe to rely on the base
movements.
* src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine
into...
(ps_table_realloc): ... this function based on `FT_REALLOC`.
(ps_table_done): Simplified.
(ps_table_add): Updated.
(CMakeLists.txt): Check the availability of `bzip2.pc'.
* If `bzip2.pc' is available, Requires.private should include
bzip2, but Libs.private should not include -lbz2.
* If `bzip2.pc' is unavailable, Requires.private cannot include
bzip2, but Libs.private should include -lbz2.
Fix#897.
* src/base/ftrfork.c (raccess_make_file_name): Do not set error.
* src/sfnt/sfdriver.c (get_win_string, get_apple_string): Ditto.
* src/cff/cffobjs.c (cff_strcpy): Do not confuse about error.
* src/psaux/psobjs.c (ps_table_done): Ditto.
* src/truetype/ttgxvar.c (ft_var_readpacked*, ft_var_load_avar): Ditto.
`FT_Outline_Decompose` does not filter out and can return degenerate
segments in an outline. This can be surprising when attemping to
stroke such an outline. Clarify the existing documentation on this
matter to cover all forms of degeneracy (without specifying exactly
how they will be reported), why they might arise, and better explain in
what cases they may be an issue.
* include/freetype/ftoutlin.h (FT_Outline_Decompose): update
documentation.
Fixes#952.
Function `map_fixed_to_sdf` expects spread to be absolute
and not squared.
* src/sdf/ftbsdf.c (finalize_sdf): Pass absolute spread
while `map_fixed_to_sdf`.
* src/sdf/ftsdf.c (sdf_generate_bounding_box): Ditto.
* src/sfnt/ttsvg.c (SVG_TABLE_HEADER_SIZE, SVG_DOCUMENT_RECORD_SIZE,
SVG_DOCUMENT_LIST_MINIMUM_SIZE, SVG_MINIMUM_SIZE): New macros.
(tt_face_load_svg): Check offsets.
Check table and record sizes.

https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43918
* builds/unix/configure.raw: Check for 'librsvg'.
(LIB_CLOCK_GETTIME): Don't call `AC_SUBST` on this but on...
(FT_DEMO_CFLAGS, FT_DEMO_LDFLAGS): ... these two new variables.
* builds/unix/unix-cc.in (LIB_CLOCK_GETTIME): Replaced by...
(FT_DEMO_CFLAGS, FT_DEMO_LDFLAGS): ... these two new variables.
