7b3ebb9c12 [sdf] Do not throw errors for invisible glyphs.
* 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.

6fb7b7a09d autogen.sh: Fix building when freetype is itself a git submodule.
There are situations where .git is not a directory, like when
freetype is a submodule in another repository.

581dd06405 [truetype] Reset IUP flags in TT_RunIns.
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.

d59c7ce1b9 [meson] Remove default_library=both from default_options.
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.

3100c8120e .gitlab-ci.yml: Add a Universal Windows build target

a1ca701023 [sfnt] Correct FT_ColorStopIterator documentation.
* 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

335224beee [sfnt] Fix bounds check in SVG.
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.

034e5dbf92 [psaux] Full bounds check for OtherSubr 19.
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`.
