+
+2013-06-18 Andrew Church <achurch+savannah@achurch.org>
+
+ Fix Savannah bug #39266.
+
+ If memory allocations fail at certain points while opening a font,
+ FreeType can either crash due to a NULL dereference or leak memory.
+
+ * include/freetype/internal/ftobjs.c (FT_Face_InternalRec,
+ FT_LibraryRec): Make `refcount' a signed integer. If, for example,
+ FT_Open_Face() fails in a memory allocation before the face's
+ reference count is set to 1, a subsequent `FT_Done_Library' call
+ would otherwise loop over `FT_Done_Face' 2^32 times before freeing
+ the face.
+
+ * src/base/ftobjs.c (open_face): Initialize `stream' and friends
+ earlier.
+ (FT_Open_Face) <Fail>: Behave correctly if `node' is NULL.
+ (FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
+
+2013-06-14 Werner Lemberg <wl@gnu.org>

+ FT_Err_Glyph_Too_Big, retry unhinted and scale up later on.
+
+2013-06-12 Werner Lemberg <wl@gnu.org>
+
+ Another try on pragmas.
+
+ * include/freetype/internal/ftdebug.h: Move pragmas to...
+ * include/freetype/internal/internal.h: ... this file since it gets
+ included by all source files.
+ * include/freetype/internal/ftserv.h: Remove pragma which has no
+ effect.
+
+2013-06-12 Werner Lemberg <wl@gnu.org>
+
+ * include/freetype/internal/ftdebug.h: Disable MSVC warning C4127.
+
+ This partially undoes commit 3f6e0e0c.
+
+2013-06-12 Werner Lemberg <wl@gnu.org>
+
+ More compiler warning fixes.
+
+ */*: Use cast to `FT_Bool' (or `Bool') where appropriate.
+
+2013-06-10 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Improve handling of broken sbit advance widths.
+
+ * src/truetype/ttgload.c (TT_Load_Glyph): Use the glyph's (scaled)
+ `linearHoriAdvance' if the sbit's `horiAdvance' value is zero.
+
+ Cf. font `Fixedsys Excelsior' v3.01 (FSEX300.ttf), glyph A, 16ppem.

+2013-06-10 Werner Lemberg <wl@gnu.org>

+ for the degenerate case.
+
+2013-06-09 David Turner <digit@google.com>
+
+ * src/cache/ftcmanag.c (FTC_Manager_Reset): Add missing cache flush.
+
+ This code, present since eight(!) years in the unused `CACHE'
+ branch, has been forgotten to apply to the master branch. It's
+ really amazing that noone has ever complained since
+ `FTC_Manager_Reset' is pretty useless without flushing the cache.

+2013-06-06 Dave Arnold <darnold@adobe.com>
+
+ [cff] Add early exit feature for width-only calls.
+
+ This is for `FT_Get_Advance'.
+
+ There are 7 places where the spec says the width can be defined:
+
+ hstem/hstemhm
+ vstem/vstemhm

+ Problem reported by Ingmar Sittl <ingmar.sittl@elektrobit.com>.
+
+2013-06-04 Werner Lemberg <wl@gnu.org>
+
+ Apply fixes for cppcheck nitpicks.
+
+ http://cppcheck.sourceforge.net/
+
+ The call was (from the top-level of the FreeType tree):
+
+ cppcheck --force \
+ --enable=all \
+ -I include \
+ -I include/freetype/ \
+ -I include/freetype/config/ \
+ -I include/freetype/internal/ \
+ . &> cppcheck.log
+
+ Note that the current version heavily chokes on FreeType, delivering
+ many wrong results. I will report those issues to the cppcheck team
+ so that a newer version gives improved results hopefully.
+
+ */* Improve variable scopes.
+ */* Remove redundant initializations which get overwritten.
+
+ * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable):
+ Remove unused variable.

+
+2013-05-23 Behdad Esfahbod <behdad@google.com>
+
+ Add support for color embedded bitmaps (eg. color emoji).
+
+ A new load flag, FT_LOAD_COLOR, makes FreeType load color
+ embedded-bitmaps, following this draft specification
+
+ https://color-emoji.googlecode.com/git/specification/v1.html
+
+ which defines two new SFNT tables, `CBDT' and `CBLC' (named and
+ modeled after `EBDT' and `EBLC', respectively). The color bitmaps
+ are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
+ pre-multiplied sRGB images. If PNG support is available, PNG color
+ images as defined in the same proposed specification are supported
+ also.
+
+ Note that color bitmaps are converted to grayscale if client didn't
+ ask for color.
+
+ * builds/unix/configure.raw: Search for libpng.

+ [cff] Make Adobe CFF engine work correctly on 64bit hosts.
+
+ Reported by numerous people on the `freetype-devel' list. Without
+ this fix, glyphs aren't properly aligned on a common baseline.
+
+ On 64bit systems, `FT_Pos' expands to `long int', having a width of
+ 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on
+ 64bit hosts also. Wrong casts filled up the blues arrays with

+
+ [cff] Add a new Type 2 interpreter and hinter.
+
+ This work, written by Dave Arnold <darnold@adobe.com> and fully
+ integrated into FreeType by me, is a donation by Adobe in
+ collaboration with Google. It is vastly superior to the old CFF
+ engine, and it will replace it soon. Right now, it is still off by
+ default, and you have to explicitly select it using the new
+ `hinting-engine' property of the cff driver.
+
+ For convenience, (most of) the new files are committed separately.

+
+2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de>
+
+ Respect CONFIG_SHELL from the environment.
+
+ Some large packages using FreeType have to use a broken (deficient)
+ /bin/sh. The configure scripts (as generated by Autoconf) are
+ clever enough to find a better shell and put that one into the
+ environment variable CONFIG_SHELL. If that environment variable is
+ already set the script skips the test and assumes to be already
+ running under a good shell.
+
+ * builds/unix/detect.mk: Honour CONFIG_SHELL.

+
+ New error management macros.
+
+ * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...

+
+2013-03-14 Werner Lemberg <wl@gnu.org>
+
+ */*: Use FT_Err_Ok only.
+
+ This is a purely mechanical conversion.
+
+2013-03-14 Werner Lemberg <wl@gnu.org>
+
+ */*: Use `FT_THROW'.
+
+ This is essentially a mechanical conversion, adding inclusion of
+ `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
+ stand-alone compiling modes of the rasterizer modules.
+
+ To convert the remaining occurrences of FT_Err_XXX and friends it is
+ necessary to rewrite the code. Note, however, that it doesn't harm
+ if some cases are not handled since FT_THROW is a no-op.
+
+2013-03-13 Werner Lemberg <wl@gnu.org>
+
+ Introduce `FT_THROW' macro.
+
+ The idea is to replace code like
+
+ return FT_Err_Foo_Bar;
+
+ or
+
+ return CFF_Err_Foo_Bar;
+
+ with
+
+ return FT_THROW( Foo_Bar );
+
+ The FT_THROW macro has two functions:
+
+ . It hides the module specific prefix.
+
+ . In debug mode, it calls the empty function `FT_Throw' which can
+ be thus used to set a breakpoint.
+
+ * include/freetype/internal/ftdebug.h (FT_THROW): New macro.
+ (FT_Throw): New prototype.
+ * src/base/ftdebug.c (FT_Throw): New function.
+
+2013-03-12 Werner Lemberg <wl@gnu.org>
+
+ Remove `FT_KEEP_ERR_PREFIX'.
+
+ The idea is to always have FT_ERR_PREFIX available internally.
+
+ * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
+ undefinition of FT_ERR_PREFIX
+
+ * src/gxvalid/gxverror.h, src/otvalid/otverror.h,
+ src/sfnt/sferrors.h: Updated.

+
+2013-03-11 Werner Lemberg <wl@gnu.org>

+
+ * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c

+
+ * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
+
+ BTW, Greg agrees that the OpenType specification is missing the list
+ of GS variables which will always be reset to the default values
+ after the `prep' table has been executed.
+
+2013-02-06 Werner Lemberg <wl@gnu.org>
+
+ * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
+
+ Up to now, we simply took a snapshot of the Graphics State after the
+ `prep' table has been executed, and right before a glyph's bytecode
+ was run it got reloaded. However, as Greg Hitchcock has told us in
+ private communication, reference points get reset to zero in the MS
+ rasterizer and we follow in due course. While reasonable, this is
+ undocumented behaviour.
+
+ Most notably, this fixes the rendering of Arial's `x' glyph in
+ subpixel hinting mode.

+
+ [truetype] Improve sub-pixel code.
+
+ This patches fixes many issues with the ttsubpix implementation.
+
+ 1. Data tables are defined, instead of declared, in the header, and
+ thus copied into each source file that includes it.
+
+ 2. These tables were defined as global, mutable, visible variables,
+ and thus costing private RAM to every process that loads the
+ library (> 50 KB / process, this is huge!).
+
+ Additionally, this also made the library export the symbols
+ completely needlessly.
+
+ 3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
+
+ Note that this doesn't try to fix the incredibly inefficient storage
+ format for the data tables used by the code. This one will require
+ another pass in the future.

+ [truetype] Improve accuracy of normalization of short vectors.
+
+ Unit vector components are stored as 2.14 fixed-point numbers. In

+
+ [truetype] Kill very old vector normalization hacks.
+
+ Back in the days, vector length calculations were not very accurate
+ and the vector normalization function, Normalize, had to meticulously

+ longer necessary after accurate CORDIC algorithms were adopted, but
