This causes a speed-up of approx. 20% for getting advance widths.

* 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.

Fixes #1157.

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

* 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 #1151.

There are situations where .git is not a directory, like when
freetype is a submodule in another repository.

Fixes mingw compilation described in !159.

* builds/windows/ftsystem.c: Do not use WINAPI_FAMILY_PARTITION macro.

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.

This can happen if the function is called with `size` being `NULL`.

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

properties.
