-	* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive

-	modernization measures.

-	This brings up the minimum required CMake version to 2.8.12.

-	The installation paths follow the GNU defaults now, e.g. installing on a

-	64 bit host will place binaries into the lib64/ folder on e.g. Fedora.

-	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

-	CMake will no longer look for a C++ compiler.

-	Library and .so version now match the Autotools build.

-	Comments in the build file and informational messages now use platform

-	agnostic example commands.

-	ftoption.h and ftconfig.h are written directly without a redundant `-new'

-	copy.

-	External dependencies are expressed as option()s and will turn up as such

-	in cmake-gui.

-	Internal: Properties such as dependencies and include directories are now

-	privately set on the freetype library instead of globally.

-	The CPack definitions have been cleaned up, the `make dist' has been

-	removed. Source packages generated with CPack don't contain Autotools

-	files and aren't used by the maintainers anyway.

-	On Windows, src/base/ftver.rc is compiled to decorate the library with

-	version and copyright information.

-	A pkg-config file is now generated and installed.

-	in above.

-2018-04-01  Werner Lemberg  <[email protected]>

-	* builds/toplevel.mk (work): Use $(SEP).

-	This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this

-	platform, and this program only understands backslashes in paths.

-	[psaux] Fix Type 1 glyphs with too many stem hints.

-	According to the CFF specification, charstrings can have up to 96 stem

-	hints. Due to hint replacement routines in Type 1 charstrings, some

-	glyphs are rejected by the Adobe engine, which implements the above

-	limit. This fix turns off hinting for such glyphs.

-	* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling

-	`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off

-	hinting.

-	Add `FT_Done_MM_Var'.

-	This is necessary in case the application's memory routines differ

-	from FreeType.  A typical example is a Python application on Windows

-	that calls FreeType compiled as a DLL via the `ctypes' interface.

-	* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare

-	and define.

-	* docs/CHANGES: Updated.

-2018-01-03  Werner Lemberg  <[email protected]>

-	[truetype] Make blend/design coordinate round-tripping work.

-	Behdad reported that setting blend coordinates, then getting design

-	coordinates did incorrectly return the default instance's

-	coordinates.

-	Use Adobe hinting engine for `light' hinting of both CFF and Type 1.

-	Since Ewald Hew factored the Adobe hinting engine out of the CFF

-	driver code, we can now use it on Type 1 (and CID) font formats, as

-	both have the same hinting philosophy.

-	This change activates the Adobe hinter when in LIGHT mode, and

-	therefore always unless explicitly asking for the auto-hinter.  This

-	makes LIGHT behavior consistent with CFF fonts.  As of this commit,

-	[cff] Fix family name logic of pure CFF fontdata (#52056).

-	1. If `FamilyName' is present in the CFF font, use this for

-	   FT_Face's `family_name'.

-	2. Otherwise, use the face name and chop off any subset prefix.

-	3. If at this point FT_Face's `family_name' is set, use this

-	   together with the full name to determine the style.

-	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.

-	5. If we don't have a valid style, use "Regular".

-	Previously, FT_Face's `family_name' entry for pure CFF fontdata

-	nearly always was the fontname itself, instead of the `FamilyName'

-	entry in the CFF font (assuming there is one).

-	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

+	64 bit host will place binaries into the lib64/ folder on e.g. Fedora.

+	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

+	CMake will no longer look for a C++ compiler.

+	Library and .so version now match the Autotools build.

+	Comments in the build file and informational messages now use platform

+	agnostic example commands.

+	ftoption.h and ftconfig.h are written directly without a redundant `-new'

+	copy.

+	External dependencies are expressed as option()s and will turn up as such

+	in cmake-gui.

+	Internal: Properties such as dependencies and include directories are now

+	privately set on the freetype library instead of globally.

+	The CPack definitions have been cleaned up, the `make dist' has been

+	removed. Source packages generated with CPack don't contain Autotools

+	files and aren't used by the maintainers anyway.

+	On Windows, src/base/ftver.rc is compiled to decorate the library with

+	version and copyright information.

+	A pkg-config file is now generated and installed.

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Fix Type 1 hinting.

+	Type 1 hinting breaks sometimes when mid-charstring hints should

+	have been in the initial hintmap.  This fix adds a preprocessing

+	pass that reads all hints and builds the correct initial hintmap

+	first, before proceeding to build the glyph outline.

+	* src/psaux/psintrp.c (cf2_interpT2CharString): New

+	`initial_map_ready' boolean flag.

+	[psaux] Change subfont synthesis for CID fonts.

+	Change `t1_make_subfont' to take in the Private dict record as an

+	argument.  This is because Type 1 and CID font records in FreeType

+	have this in different places.

+	* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to

+	`FT_Face' so that CID is also accepted.

+	* src/psaux/psintrp.c (cf2_interpT2CharString)

+	<cf2_escCALLOTHERSUBR>: Copy code from

+	[psaux] Extend Adobe interpreter (pop).

+	* src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Extend Adobe interpreter (callsubr).

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Extend Adobe interpreter (div, four-byte numbers).

+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add

+	Type 1 mode.  Type 1 requires large integers to be followed by

+	`div'; cf. `Adobe Type 1 Font Format', section 6.2.

+	<op == 255>: Push Type 1 four-byte numbers as `Int' always.  This is

+	to ensure `div' and `callsubr' get values they can use.

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Extend Adobe interpreter (hints).

+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,

+	cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode.

+	Allow adding hints mid-charstring.

+	<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands

+	for three normal stem hints.  This requires some recalculation of

+	stem positions.

+	Correction for left sidebearing.

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Extend Adobe interpreter (hsbw, sbw).

+	first operation in a Type 1 charstring.

+	(cf2_interpT2CharString): Remove unused variables.

+	<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Add Type 1 operations to Adobe CFF interpreter.

+	The following Type 1 specific ops have been added (copied from

+	`t1decode'):

+	  vstem3

+	  hstem3

+	  seac

+	  sbw

+	  callothersubr

+	  pop

+	  setcurrentpoint

+	  hsbw

+	The following require a Type 1 mode, because of differences in

+	specification:

+	  hstem

+	  vstem

+	  vmoveto

+	  callsubr

+	  div

+	  rmoveto

+	  hmoveto

+	  Numbers

+	The subsequent commits will implement these changes and adapt

+	* src/psaux/psintrp.c: Add opcodes to enum.

+	(cf2_interpT2CharString): Copy relevant code over from

+2017-09-25  Ewald Hew  <[email protected]>

+	[type1] Fixes for rendering.

+	The Type 1 advance width calculation passes null for glyph slot,

+	etc, which can cause null pointer access in the new interpreter.

+	Fall back to the old one for now.

+	are set properly.

+	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Add missing objects (2/2).

+	Synthesize a `SubFont' object for Type 1 fonts.  This is used in the

+	be used in either mode.

+	* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy

+	required values to a dummy `CFF_SubFont' object.  This is similar to

+2017-09-25  Ewald Hew  <[email protected]>

+	[psaux] Add missing objects for Type 1 (1/2).

+	to `FT_Face'.

+	Remove unused fields.

+	[otvalid] Fix handling of ValueRecords.

+	For GPOS pair positioning format 1 the description of ValueRecords

+	in the OpenType specification (1.8.2, from today) is wrong – the

+	offset has to be taken from the parent structure; in this case the

+	`PairSet' table.

+	* src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'.

+	(otv_PairPos_validate): Adjust.

+2017-09-23  Werner Lemberg  <[email protected]>

+	[otvalid] Handle `GSUB' and `GPOS' v1.1 tables.

+	`is_default_instance'.

+2017-09-21  Werner Lemberg  <[email protected]>

+	[truetype] Fix `mmvar' array pointers, part 2.

+	The previous commit was incomplete.

+	* src/truetype/ttgxvar.c: Properly initialize sub-array offsets for

+	`master' also.

+2017-09-21  Werner Lemberg  <[email protected]>

+	[truetype] Fix `mmvar' array pointers.

+	Without this change, clang's AddressSanitizer reports many runtime

+	errors due to misaligned addresses.

+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Use multiples of pointer

+	size for sub-array offsets into `mmvar'.

+	[_DLL]: Use Visual C++ extensions.

+2017-09-19  John Tytgat  <[email protected]>

+	[cff] Fix family name logic of pure CFF fontdata (#52056).

+	1. If `FamilyName' is present in the CFF font, use this for

+	   FT_Face's `family_name'.

+	2. Otherwise, use the face name and chop off any subset prefix.

+	3. If at this point FT_Face's `family_name' is set, use this

+	   together with the full name to determine the style.

+	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.

+	5. If we don't have a valid style, use "Regular".

+	Previously, FT_Face's `family_name' entry for pure CFF fontdata

+	nearly always was the fontname itself, instead of the `FamilyName'

+	entry in the CFF font (assuming there is one).

+	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

+2017-09-18  Alexei Podtelezhnikov  <[email protected]>

+	[build] Declutter Visual C++ 2010-2017 project.
