-
- [autofit] Add more Indic scripts with hanging baseline.
-
- * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
- Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
- added.
-
-2011-04-21 Behdad Esfahbod <behdad@behdad.org>
-
- Always ignore global advance.
-
- This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
- deprecated, and ignored. The new behavior is what every major user
- of FreeType has been requesting. Global advance is broken in many
- CJK fonts. Just ignoring it by default makes most sense.
-
- * src/truetype/ttdriver.c (tt_get_advances),
- src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
- tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
- src/truetype/ttgload.h: Implement it.
-
- * docs/CHANGES: Updated.

-
- [autofit] Blur CJK stems if too many to preserve their gaps.
-
- When there are too many stems to preserve their gaps in the
- rasterization of CJK Ideographs at a low resolution, blur the
- stems instead of showing clumped stems. See
- http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html
- http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html
- for details.
-
- * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
- the previous stem by `has_last_stem' and `last_stem_pos', and skip
- a stem if the current and previous stem are too near to preserve
- the gap.
-
-2011-04-18 Werner Lemberg <wl@gnu.org>
-
- Integrate autofitter debugging stuff.
-
- * devel/ftoption.h, include/freetype/config/ftoption.h

-
- Fix Savannah bug #33047.
-

- * src/psaux/psobjs.c (ps_table_add): Use FT_PtrDist for pointer
- difference.
-
-2011-04-11 Kan-Ru Chen <kanru@kanru.info>
-
- Fix reading of signed integers from files on 64bit platforms.
-
- Previously, signed integers were converted to unsigned integers, but
- this can fail because of sign extension. For example, 0xa344a1eb
- becomes 0xffffffffa344a1eb.
-
- We now do the reverse which is always correct because the integer
- size is the same during the cast from unsigned to signed.
-
- * include/freetype/internal/ftstream.h, src/base/ftstream.c
- (FT_Stream_Get*): Replace with...
- (FT_Stream_GetU*): Functions which read unsigned integers.
- Update all macros accordingly.
-

-
- [truetype] Protect jump instructions against endless loops.
-
- * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error
- if offset is zero.
-
-2011-01-31 Werner Lemberg <wl@gnu.org>
-
- [truetype] Improve handling of invalid references.
-
- * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
- error codes only if pedantic hinting is active. At the same time,
- try to provide sane values which hopefully allow useful
- continuation. Exception to this is CALL and LOOPCALL – due to
- possible stack corruption it is necessary to bail out.
-
-2011-01-31 Werner Lemberg <wl@gnu.org>
-
- [truetype] Improve handling of stack underflow.
-
- * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,
- Ins_DELTAC): Exit with error only if `pedantic_hinting' is set.
- Otherwise, try to do something sane.
-
-2011-01-30 Werner Lemberg <wl@gnu.org>
-

- case of error.
-
-2011-01-18 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix handling of MIRP instruction.
-
- Thanks to Greg Hitchcock who explained the issue.
-
- * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
- `>' since the description in the specification is incorrect.
- This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
- 65 medium' at 15ppem.
-
-2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Fix ARM assembly code in include/freetype/config/ftconfig.h.
-
- * include/freetype/config/ftconfig.h (FT_MulFix_arm):
- Copy the maintained code from builds/unix/ftconfig.in.
- Old GNU binutils could not accept the reduced syntax
- `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
- `orr %0, %0, %2, lsl #16' is better. Reported by
- Johnson Y. Yan. The bug report by Qt developers is
- considered too.
-
- http://bugreports.qt.nokia.com/browse/QTBUG-6521
-
-2011-01-15 Werner Lemberg <wl@gnu.org>
-
- [raster] Make bbox handling the same as with Microsoft's rasterizer.
-
- Right before B/W rasterizing, the bbox gets simply rounded to
- integers. This fixes, for example, glyph `three' in font `Helvetica
- Neue LT Com 65 Medium' at 11ppem.
-
- Thanks to Greg Hitchcock who explained this behaviour.
-
- * src/raster/ftrend1.c (ft_raster1_render): Implement it.
-
-2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
-
- * builds/unix/configure.raw: Consider recent gcc-standard
- flags to specify architecture in CFLAGS & LDFLAGS
- harmonization. Requested by Savannah bug #32114, to
- support multilib feature of BuildRoot SDK correctly.
-
-2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
-
- * builds/unix/configure.raw: Some important options that
- included in CFLAGS but not in LDFLAGS are copied to
- LDFLAGS, but the last option in CFLAGS was not checked.
-
-2011-01-13 Werner Lemberg <wl@gnu.org>
-
- [raster] Add undocumented drop-out rule to the other bbox side also.
-
- * src/raster/ftraster.c (Vertical_Sweep_Drop,
- Horizontal_Sweep_Drop): Implement it.
-
-2011-01-13 Werner Lemberg <wl@gnu.org>
-
- [raster] Reduce jitter value.
-
- This catches a rendering problem with glyph `x' from Tahoma at
- 10ppem. It seems that the increase of the precision in the change
- from 2009-06-11 makes a larger jitter value unnecessary.
-
- * src/raster/ftraster.c (Set_High_Precision): Implement it.
-
-2011-01-13 Werner Lemberg <wl@gnu.org>
-
- [raster] Handle drop-outs at glyph borders according to Microsoft.
-
- If a drop-out rule would switch on a pixel outside of the glyph's
- bounding box, use the right (or top) pixel instead. This is an
- undocumented feature, but some fonts like `Helvetica Neue LT Com 65
- Medium' heavily rely on it.
-
- Thanks to Greg Hitchcock who explained this behaviour.
-
- * src/raster/ftraster.c (Vertical_Sweep_Drop,
- Horizontal_Sweep_Drop): Implement it.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Fix Savannah bug #31923, patch drafted by Harsha.
-
- When a node comparator changes the cached nodes during the
- search of a node matching with queried properties, the
- pointers obtained before the function should be updated to
- prevent the dereference to freed or reallocated nodes.
- To minimize the rescan of the linked list, the update is
- executed when the comparator notifies the change of cached
- nodes. This change depends previous change:
- 38b272ffbbdaae276d636aec4ef84af407d16181
-
- * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
- top node if the cached nodes are changed.
- * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Notice if a cache query induced the node list change.
-
- Some node comparators (comparing the cache node contents and the
- properties specified by the query) can flush the cache node to
- prevent the cache inflation. The change may invalidate the pointers
- to the node obtained before the node comparison, so it should be
- noticed to the caller. The problem caused by the cache node
- changing is reported by Harsha, see Savannah bug #31923.
-
- * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
- `FT_Bool* list_changed' to indicate the change of the cached nodes
- to the caller.
- (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
- `_list_changed'.
- (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
- and update it when `FTC_Manager_FlushN' flushes any nodes.
-
- * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
- FTC_Node_CompareFunc type.
- (ftc_gnode_compare): Ditto.
-
- * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes (anyway, it
- is always FALSE).
-
- * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (ftc_cmap_node_remove_faceid): Ditto.
-
- * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
- `FTC_CACHE_TRYLOOP_END', because the result is not needed.
- (FTC_Cache_Lookup): Watch the change of the cache nodes by
- `list_changed'.
- (FTC_Cache_RemoveFaceID): Ditto.
-
- * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_gnode_compare'.
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
-
- * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes, anyway. It
- is updated by `FTC_CACHE_TRYLOOP'.
- (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
-
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
- argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
- prototype.
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
- `cache' is not used by its child `ftc_gnode_compare'.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Deduplicate the code to get the top node by a hash.
-
- There are several duplicated code fragments getting the top node
- from a cache by a given hash, like:
-
- idx = hash & cache->mask;
- if ( idx < cache->p )
- idx = hash & ( cache->mask * 2 + 1 );
- pnode = cache->buckets + idx;
-
- To remove duplication, a cpp-macro to do same work
- `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
- configuration, non-`ftc_get_top_node_for_hash' is also introduced.
-
- * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
- and implement inlined version.
- (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
- * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
- version.
- (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
- (ftc_node_hash_link): Ditto.
- (FTC_Cache_Lookup): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] inline-specific functions are conditionalized.
-
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
- inlined configuration. This function is a thin wrapper of
- `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
- `nodecmp' argument). Under non-inlined configuration,
- `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
- `FTC_Cache->clazz.node_compare'.
-
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
- * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
- `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Correct a type mismatch under non-inlined config.
-
- * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
- takes the node via a pointer `FTC_Node*', differently from cpp-macro
- `FTC_CACHE_LOOKUP_CMP'.
-
-2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Update Jamfile to include Bzip2 support.
-
- * Jamfile: Include src/bzip2 to project.
- Comments for lzw, gzip, bzip2 are changed to clarify that
- they are for compressed PCF fonts, not others.
- (e.g. compressed BDF fonts are not supported yet)
-
-2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-

-2010-12-25 Harsha <mm.harsha@gmail.com>
-
- Apply Savannah patch #7422.
-
- If we encounter a space in a string then the sbit buffer is NULL,
- height and width are 0s. So the check in ftc_snode_compare will
- always pass for spaces (comparision with 255). Here the comments
- above the condition are proper but the implementation is not. When
- we create an snode I think it is the proper way to initialize the
- width to 255 and then put a check for being equal to 255 in snode
- compare function.
-
- * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
- value 255.
- (ftc_snode_compare): Fix condition.

-
-2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Change the hash types to FT_PtrDist.
-
- On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
- variables are inappropriate to calculate hash values
- from the memory address (64-bit). The hash variables
- are extended from FT_ULong to FT_PtrDist and new
- hashing macro functions are introduced. The hash
- values on 16-bit memory platforms are changed, but
- ILP32 and LP64 are not changed. The hash value in
- the cache subsystem is not reverted to the memory
- address, so using signed type FT_PtrDist is safe.
-
- * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
- function to replace `FTC_FACE_ID_HASH' for portability.
- * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
- `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
- * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
-
- * src/cache/ftccache.h (FTC_NodeRec): The type of the
- member `hash' is changed from FT_UInt32 to FT_PtrDist.
-
- * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
- argument `hash' is changed from FT_UInt32 to FT_PtrDist.
- (FTC_Cache_NewNode): Ditto.

- (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
- * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
- * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
-
- * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
- of the internal variable `hash' is changed to FT_PtrDist
- from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
- (FTC_SBitCache_Lookup): Ditto.
- (FTC_SBitCache_LookupScaler): Ditto.
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.

- Also the type of the internal variable `_idx' is changed to
- FT_PtrDist from FT_UFast for better pointer calculation.
-
-2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Hide internal macros incompatible with LLP64.
-
- `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
- `FTC_IMAGE_TYPE_HASH' are enclosed by
- FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
- normal clients.
-
- For the history of these macros, see the investigation:

-
-2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
-
- On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
- cannot cover the memory address (64-bit). `FT_MEM_VAL' is
- used for hashing only and not dereferred, so using signed
- type FT_PtrDist is safe.
-
- * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
- return value from FT_ULong to FT_PtrDist.
- (ft_mem_table_resize): The type of hash is changed to
- FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
-
-2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Replace "%lx" for memory address by "%p", LLP64 platforms.
-
- On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
- the memory address (64-bit). Also the casts from the pointer
- type to long int should be removed to preserve the address
- correctly.
-
- * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
- (End_Profile) Ditto.
- * src/truetype/ttinterp.c (Init_Context): Ditto.
-

-
- [raccess] Skip unrequired resource access rules by Darwin VFS.
-
- When a resource fork access rule by Darwin VFS could open the
- resource fork but no font is found in it, the rest of rules
- by Darwin VFS are skipped. It reduces the warnings of the
- deprecated resource fork access method by recent Darwin kernel.
- Fix MacPorts ticket #18859:
- http://trac.macports.org/ticket/18859
-
- * src/base/ftobjs.c (load_face_in_embedded_rfork):
- When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
- means that the file is possible to be `fopen'-ed but zero-sized.
- Also there is a case that the resource fork is not zero-sized,
- but no supported font exists in it. If a rule by Darwin VFS
- falls into such cases, there is no need to try other Darwin VFS
- rules anymore. Such cases are marked by vfs_rfork_has_no_font.
- If it is TRUE, the Darwin VFS rules are skipped.
-
-2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [raccess] Grouping resource access rules based on Darwin VFS.
-
- MacOS X/Darwin kernel supports a few tricky methods to access
- a resource fork via ANSI C or POSIX interface. Current resource
- fork accessor tries all possible methods to support all kernels.
- But if a method could open a resource fork but no font is found,
- there is no need to try other methods older than tested method.
- To determine whether the rule index is for Darwin VFS, a local
- function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
- To use this function in ftobjs.c etc but it should be inlined,
- it is exposed by ftbase.h.
-
- * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
- the rules to access the resource fork.
- (raccess_guess_rec): New structure to bind the rule function and
- rule enum type.
- (FT_Raccess_Guess): The list of the rule functions is replaced by
- (raccess_guess_table): This. This is exposed to be used by other
- intra module functions.
- (raccess_rule_by_darwin_vfs): A function to return a boolean
- if the rule specified by the rule index is based on Darwin VFS.
-
-2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Prevent to open a FT_Stream for zero-sized file on non-Unix.
-
- builds/unix/ftsystem.c prevents to open an useless stream from
- zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
- stream drivers for ANSI C, Amiga and VMS return useless streams.
- For cross-platform consistency, all stream drivers should act
- same.
-
- * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
- file is zero, FT_Err_Cannot_Open_Stream is returned.
- * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
- * src/vms/ftsystem.c (FT_Stream_Open): Ditto.

- [sfnt] Prevent overrunning in `post' table parser.
- See Savannah bug #31040.
-
- * src/sfnt/ttpost.c (load_post_names): Get the length of `post'
- table and pass the limit of `post' table to `load_format_20' and
- `load_format_25'.
- (load_format_20): Stop the parsing when we reached at the limit of
- `post' table. If more glyph names are required, they are filled by
- NULL names.

-
- [truetype] Don't duplicate size->twilight structure to be freed.
- See Savannah bug #31040 for detail.
-
- * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
- FT_GlyphZoneRec size->twilight to be freed. If duplicated,
- `FT_FREE' erases the duplicated pointers only and leave original
- pointers. They can cause the double-free crash when the burst
- errors occur in TrueType interpreter and `free_buffer_in_size' is
- invoked repeatedly.
-
-2010-09-15 Werner Lemberg <wl@gnu.org>
-
- Make bytecode debugging with FontForge work again.
-
- * src/truetype/ttinterp.c (TT_RunIns): Don't call
- `free_buffer_in_size' in case of error if a debugger is active.
-
-2010-09-14 Werner Lemberg <wl@gnu.org>
-

-
- Fix minor issues reported by <muktha.narayan@wipro.com>.
-
- * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
- redundant conditional check.
- * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
- * src/cff/cffload.c (cff_encoding_load): Remove conditional check

-
- Ignore the environmental setting of LIBTOOL.
- Patch is suggested by Adrian Bunk, to prevent unexpected
- reflection of environmental LIBTOOL. See:
- http://savannah.nongnu.org/patch/?7290
-
- * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
- $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
- by default.
- * configure: When configured for the building out of source tee,
- FT_LIBTOOL_DIR is set to $(OBJ_DIR).

-
- [truetype] Decrease the trace level catching the interpreter error.
-
- * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
- showing the error when the interpreter returns with an error,
- from` FT_TRACE7' to `FT_TRACE1'.
-
-2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [truetype] Prevent bytecode reuse after the interpretation error.
-
- * src/truetype/ttinterp.c (free_buffer_in_size): New function to
- free the buffer allocated during the interpretation of this glyph.
- (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
- an error occurs in the bytecode interpretation. The interpretation
- of invalid bytecode may break the function definitions and referring
- them in later interpretation is danger. By unsetting these flags,
- `fpgm' and `prep' tables are executed again in next interpretation.
-
- This fixes Savannah bug #30798, reported by Robert Święcki.

-
- [cff] Allow SIDs >= 65000.
-
- * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
- The threshold for SIDs is not applicable here. I misinterpreted the
- `SID values 65000 and above are available for implementation use'
- sentence in the CFF specification.
-
- Problem reported by Ivan Ninčić <inincic@pdftron.com>.

-
- Force hinting when the font lacks its familyname.
-
- In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
- stream may lack `name' table because they are not required. Hinting
- for nameless fonts is safer for PDFs including embedded Chinese
- fonts. Written by David Bevan, see:

- http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
-
- * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by

-
- * src/base/ftobjs.c (FT_Done_Library): Specify the order of font

-2010-05-10 Ken Sharp <ken.sharp@artifex.com>
-
- Fix Savannah bug #29846.
-
- Previously we discovered fonts which used `setcurrentpoint' to set
- the initial point of a contour to 0,0. This caused FreeType to
- raise an error, because the `setcurrentpoint' operator is only
- supposed to be used with the results from an OtherSubr subroutine.
-
- This was fixed by simply ignoring the error and carrying on.
-
- Now we have found a font which uses setcurrentpoint to actually
- establish a non-zero point for a contour during the course of a
- glyph program. FWIW, these files may be produced by an application
- called `Intaglio' on the Mac, when converting TrueType fonts to
- Type 1.
-
- The fix allows the new invalid behaviour, the old invalid behaviour
- and real proper usage of the operator to work the same way as Adobe
- interpreters apparently do.
-
- (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
- two elements of the stack to establish unconditionally the current x
- and y coordinates.
-
- Make the `flex' subroutine handling (OtherSubr 0) put the current
- x,y coordinates onto the stack, instead of two dummy uninitialised
- values.
