It's compiled for Windows 10 and up, ensuring UNICODE is set (default for UWP)
and selecting the proper WINAPI_FAMILY (WINAPI_FAMILY_APP).
Do not try to run the UWP exe in the Docker as it doesn't work.
* include/freetype/ftcolor.h (FT_ColorStopIterator): the user should not
set `p` to NULL before calling `FT_Get_Colorline_Stops`. `p` and
`num_color_stops` are set by `FT_Get_Paint`. `p` and
`current_color_stop` are updated by `FT_Get_Colorline_Stops`.
Since 'librsvg' is written in Rust, this option allows distributions to
avoid a dependency on the entire Rust toolchain to provide the FreeType demo
programs.

When building a framework using CMake with `add_subdirectory`, CMake must be
able to find `freetype-Info.plist` when configuring the framework
properties.
Fixes#1145.

* builds/toplevel.mk (do-dist): Generate `ChangeLog` entries for all commits
since version 2.11.0 (when we stopped creating this file manually).
We have to help `pkg-config` since it can't recognize that there is no
shared library installed.
Note that meson already does exactly the same.
* builds/unix/configure.raw (REQUIRES_PRIVATE, LIBS_PRIVATE): Rename to...
(PKGCONFIG_REQUIRES_PRIVATE, PKGCONFIG_LIBS_PRIVATE): This. Adjust them
depending on `$enable_shared`.
(PKGCONFIG_REQUIRES, PKGCONFIG_LIBS): New variables.

variables.
This is another bit to handle 'sbix' tables as described in the OpenType
specification.
* include/freetype/ftparams.h (FT_PARAM_TAG_IGNORE_SBIX): New macro.
* src/sfnt/sfobjc.c (is_apple_sbix): Rename to...
(has_sbix): ... this.
Check for more sbit tables.
Handle `FT_PARAM_TAG_IGNORE_SBIX` to eventually control `has_sbix`.
Only call sbit table loader if an sbit table is present.
* src/sfnt/ttsbit.c (tt_face_load_sbix_image): Correct calculation of
'metrics->horiBearingY'.
Set vertical metrics.
* src/sfnt/sfobjs.c (sfnt_load_face): Adjust setting of `FT_FACE_FLAG_SBIX`.
Handle metrics of fonts with 'sbix' table.
* src/truetype/ttgload.c (TT_Load_Glyph): For 'sbix' embedded bitmaps, apply
bbox offset and bearing values of the corresponding glyph in the 'glyf'
table if it exists and has a contour.
* src/truetype/ttobjs.c (tt_face_init): Handle font with 'sbix' table.
Fixes issue #998.
Fonts with 'sbix' tables need special handling by the application.
* include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros.
* src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix'
table is present.
In the woff2 spec it has been proposed to allow the OVERLAP_SIMPLE flag
to be retained through the woff2 format [0].
[0] https://www.w3.org/TR/WOFF2/#glyf_table_format
* src/sfnt/sfwoff2.h (GLYF_OVERLAP_SIMPLE): add glyf flag.
* src/sfnt/sfwoff2.c (reconstruct_glyf): parse optionFlags and
overlapSimpleBitmap[]. (store_points): set OVERLAP_SIMPLE on first point's
flag if the overlap bit is set.
* src/sdf/ftsdf.c (sdf_generate_bounding_box): Always check for a corner if
two distances (for different curves) are very close.
(sdf_conic_to): Check whether the conic curve can be treated as a line
(which happens if the control point coincides with any end point).
* src/sdf/ftsdf.c (split_sdf_cubic, split_sdf_shape): Add checks to figure
out the deviation of Bezier curves and stop splitting if the curve is flat
enough.
* src/sdf/ftsdfcommon.h (ONE_PIXEL): New macro.
The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not
protected by parentheses. As a result, the expression
`table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
`table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
`table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
bounds check which may lead to reading past the end of the `SVG ` table.
* src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in
parentheses.

It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
`blend->num_designs` set to 2, and the user supplied `idx` to be large (for
example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds
check overflows in a well defined manner, allowing for an invalid call to
`memcpy`.
In addition, it is possible to call OtherSubr 19 with
`decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes
the bounds check (it is logically always fine to copy nothing starting at
index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is
undefined behavior (even if `count` is zero).
* src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
`blend->num_designs` can be copied to `decoder->buildchar[idx]`.
Also avoid passing NULL to `ft_memcpy`.
Bug: https://crbug.com/1299259
* 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.
