* include/freetype/config/ftheader.h: New macro `FT_SVG_RENDERER_H'
for `freetype/svgrenderer.h'.
* include/freetype/svgrenderer.h: New file to store SVG specific
function types, SVG interface and `FT_Set_Svg_Hooks'.
* src/base/ftobjs.c: Adds implementation of `FT_Set_Svg_Hooks'.
* src/svg/ftsvg.c: Creates `svg_renderer_interface'.
* src/svg/svgtypes.c: Moves hook function types to
`FT_SVG_RENDERER_H'. Adds a hook for svg rendering. Temporary.
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.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
* builds/unix/configure.raw (version_info): Set to 23:1:17.
* CMakeLists.txt (VERSION_PATCH): Set to 1.
* include/freetype/fterrors.h (FT_Error_String): Fix C++ compilation.
* src/autofit/afglobal.c (af_face_global_get_metrics): Start again
(with dummy hinter module) if no blue zones are present.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Change
signature to return error code.
If no blue zones are found, update `glyph_styles' array to hold
AF_STYLE_NONE_DFLT instead of the current style.
(af_latin_metrics_init): Return internal error code if no blue zones
are found.
More to come.
* builds/vms/LIBS.OPT_IA64, builds/vms/_LINK.OPT_IA64,
builds/vms/vmslib.dat: New files provided by Jouk Jansen
<joukj@hrem.nano.tudelft.nl>.
* builds/vms/ftconfig.h: Update, also from Jouk.
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.
Up to now, only the unscaled CVT values were varied; in other words,
the `CVAR' data was never used for bytecode hinting.
* src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary
function.
(tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
If `CVAR' data is applied to variation fonts, fractional values are
possible.
* include/freetype/internal/tttypes.h (TT_FaceRec): Change type of
`cvt' from `FT_Short' to `FT_Int32'.
* src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro.
(tt_face_vary_cvt): Use it to update code to 26.6 format.
* src/truetype/ttobjs.c (tt_size_run_prep): Update code to 26.6
format.
* src/truetype/ttpload.c (tt_face_load_cvt): Stora data in 26.6
format.
