FT_INTERNAL_POSTSCRIPT_HINTS_H.
(cff_size_get_globals_funcs, cff_slot_init): Updated.
(cff_face_init): Follow `cff_index_get_name',
`cff_index_get_string', and `cff_index_get_sid_string' changes.
* src/cff/cffcmap.c (cff_sid_free_glyph_name): Removed.

(cff_cmap_unicode_init): Updated.
* src/cff/cffdrivr.c: Don't include PS cmap service.
(cff_get_glyph_name): Avoid unnecessary lookup for POSTSCRIPT_CMAPS
service.
(cff_get_glyph_name, cff_ps_get_font_info, cff_get_ros): Follow API
`cff_index_get_sid_string' change.
(cff_get_name_index): Use `cff_index_get_string' instead of
`cff_index_get_name'.
* src/cff/cffgload.c: Don't include FT_INTERNAL_POSTSCRIPT_HINTS_H.
(cff_decoder_init, cff_decoder_prepare): Updated.
Initialize phantom points before calling the incremental interface
to update glyph metrics.
* src/truetype/ttgload.c (tt_get_metrics_incr_overrides)
[FT_CONFIG_OPTION_INCREMENTAL]: New function, split off from...
(tt_get_metrics): This.
Updated.

Since we consider `sbw' for the horizontal direction only, we still have
to synthesize vertical metrics if the user wants to use the vertical
writing direction.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
set.
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only. For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction. Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).
* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.
* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
(cff_slot_load), src/type1/t1gload.c
(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
(cid_load_glyph): Use it.
Issue #28226 involved a work-around for a font which used the
`setcurrentpoint' operator in an invalid way; this operator is only
supposed to be used with the result of OtherSubrs, and the font used
it directly. The supplied patch removed the block of code which
checked this usage entirely.
This turns out to be a Bad Thing. If `setcurrentpoint' is being
used correctly it should reset the flex flag in the decoder. If we
don't do this then the flag never gets reset and we omit any further
contours from the glyph (at least until we close the path or
similar).
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_setcurrentpoint>: Handle `flex_state' correctly.
Ghostscript requires the incremental font interface for handling
some Postscript documents. It is moving to using FreeType as its
primary renderer; supporting this in the default build makes it
Ghostscript to be linked against the system FreeType when one is
available.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
Uncomment.
