Move `scripts/` to `src/tools`.
* scr/tools/scripts/ (_TOP_DIR,
_SCRIPT_DIR): Updated to new location.
(main): s/shutils.copyfile/shutils.copy/ to preserve file
(main): Prefix source file paths with `git_dir` while copying files

2020-09-24 Werner Lemberg <>
* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.
Towards the end of the the function there is a call to
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
is left alone, and is not scaled.

Add python script for building tarballs.
* scripts/ New file.
This standalone Python script should be equivalent to running `make
dist` with the Make-based build system, with the following minor
- Since `make distclean` doesn't always clean up `objs/` properly,
`make dist` archives may contain some stale binaries like
`objs/.libs/` or others.
- `config.guess` and `config.sub` are not updated unless option
`--gnu-config-dir=DIR` is used to specify the location of these
- Some bits of the auto-generated reference documentation may
appear in slightly different order, probably due to issues related
to mkdocs and docwriter.
As an example, the call
scripts/ /tmp/freetype2-dist
creates the following files under `/tmp/freetype2-dist`:

[raster] Improve the second pass (#58373).

[gzip] Support `gzip' encoded header conditionally.
In order to support `gzip' encoded header the call to
`inflateInit2' was modified in commit 6a92b1fadde26477a9179.
However, this code breaks with the outdated internal version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.
Problem report in
* 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.

[truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923).
By resetting the blend as implemented with this commit fonts with

we want to keep seeing the failure in `tt_set_mm_blend'.

[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
As originally intended, a Type 1 SEAC charstring would be used for
an accented glyph (like `acaron' or `uumlaut'), where the advance
width of the SEAC glyph is the same as that of the `base' glyph
(like `a' or `u'). In this case it is not uncommon for the SEAC
glyph to not use an (H)SBW opcode of its own but to rely on the
value from the base glyph.
However, out-of-spec fonts also use SEAC glyphs for ligatures (like
`oe' or `fi'), and in those cases the overall advance width is
greater than that of the `base' glyph. For this reason we have to
allow that the SEAC glyph can have an (H)SBW value of its own, and
if it has, retain this value, rather than the one from the base

[smooth] Simplify cubic Bézier flattening.
The previous implementation is correct but it is too complex.
The revised algorithm is based on the fact that each split moves
the control points closer to the trisection points on the chord.
The corresponding distances are good surrogates for the curve
deviation from the straight line.
This cubic flattening algorithm is somewhat similar to the conic
algorithm based the distance from the control point to the middle of
the chord. The cubic distances, however, decrease less predictably
but are easy enough to calculate on each step.
The new algorithm produces slightly larger number of splits, which is
compensated by its simplicity. The overall rendering performance is
improved by 1-2%. The larger number of splits does not necessarily
result in higher quality, which stays comparable.

* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
`cf2_arrstack_setCount' may fail because the allocator ran out of

error condition is checked. This means that FreeType writes outside
of allocated memory. This commit moves the error check prior to the
stack assignment, hence the function now properly returns with an
error condition.

Fix handling of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.

Improve auto-hinter handling of bitmap fonts (#54681).
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks whether the driver supports scalable
outlines, but not if the face supports scalable outlines.
