We now use a hash to map from subr indices to array elements holding
the subroutines, if necessary.
* include/freetype/internal/t1types.h: Include FT_INTERNAL_HASH_H.
(T1_FontRec): Add `subrs_hash' field.
* include/freetype/internal/psaux.h: Include FT_INTERNAL_HASH_H.
(T1_DecoderRec): Add `subrs_hash' field.
* src/type1/t1load.h (T1_LoaderRec): Add `subrs_hash' field.
* src/type1/t1driver.c: Include FT_INTERNAL_HASH_H.
(t1_ps_get_font_value) [PS_DICT_SUBR]: Look up hash if necessary.
* src/type1/t1load.c: Include FT_INTERNAL_HASH_H.
(parse_subrs): Use hash for subr indices that exceed the allocated
number of subr slots.
(t1_init_loader): Remove unnecessary code.
(t1_done_loader, T1_Open_Face): Updated.
* src/type1/t1gload.c (T1_Compute_Max_Advance, T1_Get_Advances,
T1_Load_Glyph): Updated.
* src/type1/t1objs.c (T1_Face_Done): Updated.
* src/psaux/t1decode.c: Include FT_INTERNAL_HASH_H.
(t1_decoder_parse_charstrings) [op_callsubr]: Look up hash if
necessary.
* src/cid/cidgload.c (cid_load_glyph): Updated.
* src/base/fthash.c (hash_num_lookup, hash_num_compare): New
functions.
(ft_hash_init): Add argument to select between number and string
hashing.
(ft_hash_num_insert, ft_hash_num_lookup): New functions.
* include/freetype/internal/fthash.h: Updated.
* src/bdf/bdflib.c (_bdf_parse_start): Updated.
* include/freetype/internal/fthash.c (FT_Hash_LookupFunc,
FT_Hash_CompareFunc, FT_Hash_FreeFunc): New typedefs.
(FT_HashRec): Add `lookup', `compare', and `free' fields.
* src/base/fthash.c (hash_str_lookup, hash_str_compare,
hash_str_free): New functions.
(ft_hash_init): Set function pointers.
(hash_bucket, ft_hash_free): Use them.
We want to support both an integer and a string key later on.
* include/freetype/internal/fthash.h (FT_Hashkey): New union.
(FT_HashnodeRec): Updated.
(ft_hash_insert, ft_hash_lookup): Renamed to ...
(ft_hash_str_insert, ft_hash_str_lookup): ... this.
* src/base/fthash.c (hash_bucket): Updated.
(ft_hash_insert, ft_hash_lookup): Renamed to ...
(hash_insert, hash_lookup): ... this.
(ft_hash_str_insert, ft_hash_str_lookup): New wrapper functions.
* src/bdf/bdflib.c: Updated.
Scripts like Khmer have blue zones that can't be directly
represented by Unicode characters. Instead, it is necessary to let
HarfBuzz convert character clusters into proper glyph representation
forms, then deriving the blue zone information from the resulting
glyphs.
* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
files, providing a new API to access HarfBuzz.
The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
string with function `af_shaper_get_cluster', and the resulting
glyph data (indices, advance widths, vertical offsets) can be
iteratively accessed with function `af_shaper_get_elem'.
* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
* src/autofit/aflatin.c (af_latin_metrics_init_widths,
af_latin_metrics_init_blues, af_latin_metrics_check_digits):
Updated.
* include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/.
* src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.
(af_face_globals_compute_style_coverage): Updated.
* src/autofit/afglocal.h: s/hbshim.h/afshaper.h/.
* src/autofit/autofit.c: s/hbshim.c/afshaper.c/.
* src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC):
Updated.

This does the same as `FT_LCD_FILTER_LEGACY'.
See
https://bugs.freedesktop.org/show_bug.cgi?id=92981
for the reasoning.
* include/freetype/ftlcdfil.h (FT_LcdFilter): New value
`FT_LCD_FILTER_LEGACY1'.
* src/base/ftlcdfil.c (FT_Library_SetLcdFilter): Use it.
Both the native CFF hinter and the auto-hinter now have a very
similar rendering style.

longer implies FT_LOAD_FORCE_AUTOHINT.

* builds/unix/configure.raw (version_info): Set to 18:1:12.

* src/autofit/afmodule.c [AF_DEBUG_AUTOFIT]: Ensure C linking for
dumping functions.
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values. This commit tries to improve that.
* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
tt_cmap12_char_map_binary, tt_cmap13_next,
tt_cmap13_char_map_binary): Reject glyph indices larger than or
equal to the number of glyphs.
* include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use
`FT_UShort' for `map' field.
* src/autofit/afglobal.c (af_face_globals_compute_style_coverage,
af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h
(af_get_coverage): Use FT_UShort for `glyph_styles' array.
* src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to
16 bits.
(AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font. The indices start
with value 1; value 0 indicates font access without GX variation
data.
* include/freetype/freetype.h (FT_FaceRec): Update documentation.
* include/freetype/internal/sfnt.h: Ditto.
* src/sfnt/sfobjs.c (sfnt_init_face)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and
do argument checks.
(sfnt_load_face): Updated.
* src/truetype/ttobjs.c (tt_face_init)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting
the style name.

Updated.
* docs/CHANGES: Updated.
* include/freetype/internal/sfnt.h (TT_Get_Name_Func): New
prototype.
(SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): New member `get_name'.
* src/sfnt/sfdriver.c (sfnt_interface): Updated.
* src/sfnt/sfobjs.c (tt_face_get_name): Tag it with `LOCAL_DEF'.
* src/sfnt/sfobjs.h: Add prototype for it.
The function uses Newton's iterations instead of dividing vector
components by its length, which needs a square root. This is,
literally, a bit less accurate but a lot faster.
* src/base/ftcalc.c (FT_Vector_NormLen): New function.
This change is a result of a discussion thread on freetype-devel
http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html
Re-introduce the `freetype2' subdirectory for all FreeType header
files after installation, and rename the `freetype2' subdirectory in
the git repository to `freetype'.
* include/freetype2: Renamed to...
* include/freetype: This.
* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS): Updated.
Update creation of `ftconfig.h'.
Install generated `ftconfig.h'.
* Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.
* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/freetype2.in: Updated.
* builds/unix/freetype-config.in: Updated.
* builds/unix/configure.raw: Don't check for `rmdir'.
* builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable
according to the autoconf info manual.
* builds/unix/install.mk (install, uninstall,
distclean_project_unix): Update and simplify.
* builds/wince/*, builds/windows/*: Updated.
* devel/ft2build.h, include/ft2build.h: Updated.
* include/freetype2/config/ftheader.h,
include/freetype2/internal/ftserv.h,
include/freetype2/internal/internal.h: Update all header file
macros.
* src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated.
* docs/*: Updated.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level. Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.
Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like
#include <ft2build.h>
#include FT_FREETYPE_H
...
don't need any change to the source code.
* include/freetype/*: Move up to...
* include/*: ... this directory.
* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.
*/*: Essentially do `s@/freetype/@/@' where appropriate.
* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.
Simply apply the patch from the bug report.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: The used #pragma directives only
work with gcc versions 4.6 and higher.
