9443a1bc3e Add Brotli dependency and required checks.
Brotli is required for decompressing WOFF2 font directory streams.
The library is thus being added as an optional dependency for
FreeType.

(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated.

* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_BROTLI): New macro.

05439f5cc6 [psaux] (2/2) Handle fonts that use SEAC for ligatures (#56580).

f2b64583cb [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
glyph.

* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
Implement it.

e7ac9288ac [smooth] Restore the span buffering for direct mode only.
The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be
enough to cover the entire scanline for simple glyphs in most cases:
each slightly slanted edge needs up to two spans, plus a filling span
in-between.  This is not new, we used to do it before cb4388783c.

* src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'.
(gray_hline, gray_sweep): Implement the span buffering.
(gray_raster_render): Use negative `num_spans' to avoid the direct
mode.
