`docs/reference/*' was moved one directory up in commit 237fed6.
* builds/unix/unix-def.in (PIP): Remove variable.
* configure: Create `docs' directory and copy assets from
`docs/markdown'.
* docs/README: Output directory is `reference'.
Python versions < 3.5 have reached end-of-life and as such, no
security or bug fixes will be provided for those versions. See
https://devguide.python.org/#status-of-python-branches
for more information.
* Jamfile (RefDoc): Add `site' parameter.
* builds/detect.mk (std_setup): Update Python version requirement.
* builds/freetype.mk (refdoc-venv): Use pip as `python -m pip'.
* builds/unix/ax_compare_version.m4,
builds/unix/ax_prog_python_version.m4: Macros to detect Python
version. New files.
* builds/unix/configure.raw: Check for Python >= 3.5 and remove
check for `pip'.
* docs/CHANGES, docs/INSTALL.GNU, docs/README: Updated.
In order to support `gzip' encoded header the call to
`inflateInit2' was modified in commit 6a92b1fadd.
However, this code breaks with the outdated internal version
of zlib. This is a temporary fix to conditionally support
`gzip' encoded header whenever a system installation of zlib
is being used.

https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html
* src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to
`inflateInit2' depending on whether the system installation is
being used or the internal copy.
By resetting the blend as implemented with this commit fonts with
invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
`tt_set_mm_blend' and failing, but the font was invalid anyway and
we want to keep seeing the failure in `tt_set_mm_blend'.
* src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
offset array once.
Allocate arrays after `FT_FRAME_ENTER' (extra check before
allocating and avoid needing to free array later if error entering
frame).
Always call `FT_FRAME_EXIT'.
Consistently set counts immediately after array initialized.
Reset the blend (particularly `blend->glyphoffsets') on failure.
This change is required to support docwriter 1.2.1.

for more information.
* docs/markdown/stylesheets/extra.css:
(.md-typeset code) -> (.md-typeset pre>code)
(pre) -> (pre>code)
(p, .md-typeset p, h4): Remove commented styles.
(table.index): Remove unused styles.
* src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any
`blend->xxxcount' values until the corresponding data has been
checked.
Also do some sanitizing to avoid a too early exit.
(TT_Vary_Apply_Glyph_Deltas): Improve tracing message.
* builds/unix/configure.raw, CMakeLists.txt: Request HarfBuzz 1.8.0
or newer.
We are going to add auto-hinter support for Hanifi Rohingya, which
was introduced in Unicode 11.0.
* src/base/ftpsprop.c (ps_property_set) [hinting-engine]: Avoid an
incorrect return value that caused a warning. The function did the
right thing, though.
Creating the API Reference in the (new) `reference' sub-directory is
consistent with other documentation sub-topics, such as `design',
`glyphs' and `tutorial'.
This patch fixes broken hyperlinks in the documentation pointing to
and from the API Reference. It also allows web assets to load from
their relative paths.
* builds/freetype.mk (DOC_DIR): Adjust.
(refdoc, refdoc-venv): Add `--site' argument.
* builds/toplevel.mk (do-dist): Updated.
* src/base/ftoutln.c (FT_Outline_Transform): Bail on empty points.
* src/cff/cffload.c (cff_subfont_load): Use `FT_OFFSET'.
* src/psaux/psft.c (cf2_decoder_parse_substrings): Early out if
`charstring_base' or `charstring_len' are null.
* src/sfnt/ttload.c (tt_face_load_name): Use `FT_OFFSET'.
* src/base/ftgloadr.c (FT_GlyphLoader_Adjust_Points,
FT_GlyphLoader_Adjust_Subglyphs): Use `FT_OFFSET'.
(FT_GlyphLoader_CreateExtra): Add short cut if some values are zero.
Use this for `base + offset' pointer calculations where `base' can
be NULL (triggering a sanitizer warning even if the resulting
pointer gets never dereferenced since it is undefined behaviour
in C).
