* meson.build: Fix resource compilation on Windows.
This is copied from GStreamer's meson port of FreeType.

Windows only).

* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/.
(freetype2_dep): Use it.
`ft2_libtool_version` would be the shared library version, not the
one we should use in file `freetype2.pc`.

|
* meson.build: Use `meson.override_dependency`.
This is a new meson mechanism to avoid other projects to hard-code
the `freetype2_dep` variable name in their build definition. It
also ensures that meson does not mix system and subproject versions
of FreeType inside of the same project.
Also remove outdated TODO because `declare_dependency` was already
there.

* meson.build (bzip2_dep): Simplify.
We remove `static:false` from `find_library('bz2')`.
I don't know whether the previous code was a workaround for an old
meson bug, but at least with version >=0.55.0 (which FreeType uses)
it picks the shared library when both are available.
With this commit, file `freetype2.pc` no longer contains the full path to
file `libbz2.so`; instead, it correctly uses `-lbz2`. Note that this is a
meson bug is still present in the current version (0.57.0).

* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.
This ensures good logging output, with all lines having a proper
prefix (if requested).
This is a continuation of a similar patch from 2020-12-02, which
missed some locations.

|
[sfnt] Additional checks for 'colr' table presence.
* sfnt/ttcolr.c (tt_face_get_colr_glyph_paint,
tt_face_get_colorline_stops, tt_face_get_paint): Additional checks
for whether colr table is present. Prevents crashes when these
methods are called on non-COLR fonts.

|
2021-01-14T16:06:03
|
|
Add config option to test for 'COLR' v1 support in headers.
* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are
building against supports the 'COLR' v1 API. This is intended to be
a temporary solution until 'COLR' v1 support is released in a
FreeType version and such a check can be made by using the version
number instead.

certain format, which contains the detailed information stored in a
paint of the respective format.
(read_paint): New function to provide the format specific parsing
and to populate the data members of each specific `FT_COLR_Paint`
subtype.
(read_color_line): New function to parse retrieved color line
information into an `FT_ColorLine` object, which has information
about the color line extend mode as well as an
`FT_ColorStopIterator` object.

(FT_Get_Paint_Layers): New method for retrieving the layers of a
`PaintColorGlyph`.
(FT_Get_ColorLine_Stops): New method for retrieving the stops of a
color.
(FT_Get_Paint): New method for resolving an `FT_OpaquePaint` into an
`FT_COLR_Paint` object.

[base] Allow renderers of different formats.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the
glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming
'bsdf' renderer will require bitmaps for processing.
* src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove
renderer's glyph format check before adding and removing them. The
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.

`FT_RENDER_MODE_SDF`, which will be used to generate SDF.
* include/freetype/ftimage.h (FT_Pixel_Mode): Add new pixel mode
`FT_PIXEL_MODE_GRAY16`, which will be the output of the 'sdf'
module.
(FT_RASTER_FLAG_SDF): New raster flag to be used internally by the
'sdf' module.

[autofit] Fix double division in stem darkening.
The old code used to divide the darkening amount by em_ratio twice,
leading to unnecessarily bold stems on certain fonts with higher
units per em (e.g. Inter). This patch fixes it.
The return value of af_loader_compute_darkening was also changed to
use 16.16 fixed point to get rid of a redundant truncation operation.
This should slightly improve the precision, although it's still
bottlenecked by the emboldening function, which uses 26.6 fixed point.
* src/autofit/afloader.[ch]
(af_loader_compute_darkening): Return FT_Fixed.
(af_loader_embolden_glyph_in_slot): Revise calculations.
