* include/freetype/freetype.h (FT_GlyphSlotRec_): update doc
* src/cff/cffgload.c (cff_slot_load): do it
* src/truetype/ttgload.c (TT_Load_Glyph): do it
Fixes: #1156
This issue was discovered with an SVG based font with some documents
compressed and other uncompressed. After loading the first compressed
document the ownership flag on the glyph slot was set to true but never
set to false. As a result after loading a compressed document a glyph
from an uncompressed document would load fine, but when this glyph slot
was cleared it would try to free its document resulting in a wild free.
* src/base/ftobjs.c (ft_glyphslot_clear): clear correct flags
Fixes: #1162
* include/freetype/internal/ftmmtypes.h (FT_ItemVarDelta): Define type
to be used for delta arrays, upgrade to FT_long.
* src/truetype/ttgxvar.c: Adhere to long_words bit and read either
Short/Byte pairs or Long/Short pairs, as defined by spec. For better
readability, define macro for repetitive read code.
* truetype/ttgxvar.c (tt_hvadvance_adjust, tt_apply_mvar,
tt_var_get_item_delta): Remove special 0xFFFF handling in favor of less
redundant handling inside the tt_var_get_item_delta function, as it is
equivalent to returning a 0 delta. Avoids code-duplication checking for
special value 0xFFFF.
This is a preparation for handling `DeltaSetIdxMap` and `VarStore` as a
FreeType service.
* src/truetype/ttgxvar.c (ft_var_done_delta_set_index_map): New function.
(tt_done_blend): Use it.
This is because the `git archive` command doesn't preserve submodules.
Note that currently there is no support for disabling the 'download' button
in gitlab (https://gitlab.com/gitlab-org/gitlab/-/issues/17032).
Fixes issue #1158.
This was introduced in OpenType 1.8.4.
* src/truetype/ttgxvar.c (ft_var_load_delta_set_index_mapping,
tt_hvadvance_adjust, ft_var_load_mvar, tt_apply_mvar): Handle special
inner/outer index values.
(ft_var_load_item_variation_store): Add test.
Fixes#1154.
==========================
Tag sources with `VER-2-12-1'.
* docs/VERSION.TXT: Add entry for version 2.12.1.
* docs/CHANGES, docs/release: Updated.
* README, src/base/ftver.rc, builds/windows/vc2010/index.html,
builds/windows/visualc/index.html, builds/windows/visualce/index.html,
builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html,
docs/freetype-config.1: s/2.12.0/2.12.1/, s/2120/2121/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
* builds/unix/configure.raw (version_info): Set to 24:3:18.
* CMakeLists.txt (VERSION_PATCH): Set to 1.
* src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Return `FT_Err_Ok` if
width or height is zero, since some glyphs do not generate visible bitmaps.
Fixes#1150.
Fixes#1148 by moving the flag initialization back, partly reverting
7809007a and fd03dcc1. Initializing these flags elsewhere skips 'cvt'.
* src/truetype/ttinterp.c (TT_RunIns): Initialize the IUP flag here...
(TT_Run_Context): ... instead of here.
It is inconsistent with what all other Meson projects do.
It also prevents static linking to FreeType when it is a subproject because
`default_options` in a subproject takes precedence on values set on the main
project. For example, building 'GStreamer' with `-Ddefault_library=static`
would still dynamically link on FreeType unless the user also sets
`-Dfreetype2:default_library=static`.
* meson.build: Updated.
* .gitlab-ci.yml: Retain `both` option for testing.
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.
Suggested by Lars Wendler in !156.
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.

Fixes issue #998.
Fonts with 'sbix' tables need special handling by the application.

* 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.
