        * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
        version number to 2.3.7.

        * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
        builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj,
        builds/win32/visualce/index.html,
        builds/win32/visualce/freetype.dsp,
        builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

        * builds/unix/configure.raw (version_info): Set to 9:18:3.

        * docs/release: Updated.

2008-06-28  Werner Lemberg  <wl@gnu.org>

        * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
        * src/ftcalc.c: Here.  This fixes Savannah bug #23729.

2008-06-27  Werner Lemberg  <wl@gnu.org>

        * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
        Horizontal_Gray_Sweep_Drop): Test for intersections which
        degenerate to a single point can be ignored; this has been confirmed
        by Greg Hitchcock from Microsoft.  (This was commented out code.)

2008-06-26  Werner Lemberg  <wl@gnu.org>

        Improve navigation in API reference.

        * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
        (html_header_6): This.
        (html_header_3, html_header_3i, html_header_4, html_header_5,
        html_header_5t): New strings.
        (toc_footer_start, toc_footer_end): New strings.
        (HtmlFormatter::html_header): Updated.
        (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
        New strings.
        (HtmlFormatter::index_enter): Use `html_index_header'.
        (HtmlFormatter::index_exit): Print `html_footer'.
        (HtmlFormatter::toc_enter): Use `html_toc_header'.

        Convert ~ to non-breakable space.

        * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
        Update header files accordingly.

2008-06-24  suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
        and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
        bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
        ResourceIndex type definition.  The macro does not inform the type
        availability.
        * src/base/ftmac.c: More parentheses are inserted to clarify the
        conditionals to disable legacy APIs in `10.5 and later' cases.  If
        HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.

2008-06-24  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp. (Ins_SCANTYPE): Don't check rendering mode.

        * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
        Draw_Sweep): No-dropout mode is value 2, not value 0.
        (Draw_Sweep): Really skip dropout handling for no-dropout mode.

2008-06-24  Werner Lemberg  <wl@gnu.org>

        * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
        if it consists of one point only.  Based on a patch from Savannah
        bug #23683 (from John Tytgat).

2008-06-22  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
        with IS_HINTED.

        * docs/CHANGES: Updated.

2008-06-22  suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
        but LDFLAGS does not, import it to LDFLAGS.  The option is used to
        specify non-default SDK on Mac OS X (e.g., universal binary SDK for
        Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
        recommends to add the option only to CFLAGS, LDFLAGS should include
        it because libfreetype.la is built with -no-undefined.  This fixes a
        bug reported by Ryan Schmidt in MacPorts,
        http://trac.macports.org/ticket/15331.

2008-06-21  Werner Lemberg  <wl@gnu.org>

        Enable access to the various dropout rules of the B&W rasterizer.
        Pass dropout rules from the TT bytecode interpreter to the
        rasterizer.

        * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
        FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.

        * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
        Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
        OpenType specification.
        Fix mode 4 computation.
        (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

        * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
        mode to FT_OUTLINE_XXX flags.

        * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

2008-06-19  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffobjs.c (cff_face_init): Compute final
        `dict->units_per_em' value before assigning it to
        `cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
        scaled incorrectly if the font matrix is non-standard.  This fixes
        Savannah bug #23630.

        * docs/CHANGES: Updated.

2008-06-19  Werner Lemberg  <wl@gnu.org>

        * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
        from 2008-06-19.

2008-06-18  Werner Lemberg  <wl@gnu.org>

        * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
        Reported by Peter Weilbacher <mozilla@weilbacher.org>.

        * docs/CHANGES: Updated.

2008-06-15  George Williams  <gww@silcom.com>

        * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
        `valid->extra2' to 1.  This is undocumented in the OpenType 1.5
        specification.

2008-06-15  Werner Lemberg  <wl@gnu.org>

        * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
        from clobbering.  Patch from Savannah bug report #23556.

        * docs/CHANGES: Document it.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * autogen.sh: Add option `--install' to libtoolize.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * Version 2.3.6 released.
        =========================


        Tag sources with `VER-2-3-6'.

        * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
        version number to 2.3.6.

        * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
        builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj,
        builds/win32/visualce/index.html,
        builds/win32/visualce/freetype.dsp,
        builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.

        * builds/unix/configure.raw (version_info): Set to 9:17:3.


        * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
        and `scale_y'.
        * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'.


        * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H.
        * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (open_face): Check `clazz->init_face' and
        `clazz->done_face'.

2008-06-09  VaDiM  <s_sliva@rambler.ru>

        Support debugging on WinCE.  From Savannah patch #6536; this fixes
        bug #23497.

        * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
        as a replacement for OutputDebugStringA (which WinCE doesn't have).
        Update all callers.
        (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
        environment variables.

2008-06-09  Werner Lemberg  <wl@gnu.org>

        * README.CVS: Updated.

        * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
        for newer versions of autoconf and friends.

2008-06-08  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
        `private_len' unsigned.

        * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
        it as such.
        (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.


        * src/base/ftstream.c (FT_Stream_Skip): Reject negative values.


        * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
        for sane value.
        Fix typo.


        * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.


        * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
        `last_point'.


        * src/sfnt/ttload.c (tt_face_load_max_profile): Limit
        `maxTwilightPoints'.

2008-06-06  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
        correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.

2008-06-03  Werner Lemberg  <wl@gnu.org>

        * include/freetype/ftcache.h (FTC_FaceID): Change type back to
        FT_Pointer.  Reported by Ian Britten <britten@caris.com>.

2008-06-02  Werner Lemberg  <wl@gnu.org>

        Emit header info for defined FreeType objects in reference.

        * src/tools/docmaker/content.py (re_header_macro): New regexp.
        (ContentProcessor::__init__): Initialize new dictionary `headers'.
        (DocBlock::__init__): Collect macro header definitions.

        * src/tools/docmaker/tohtml.py (header_location_header,
        header_location_footer): New strings.
        (HtmlFormatter::__init__): Pass `headers' dictionary.
        (HtmlFormatter::print_html_field): Don't emit paragraph tags.
        (HtmlFormatter::print_html_field_list): Emit empty paragraph.
        (HtmlFormatter::block_enter): Emit header info.

2008-06-01  Werner Lemberg  <wl@gnu.org>

        * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
        FT_INCREMENTAL_H): Added.

2008-05-28  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/sources.py (SourceBlock::__init__): While
        looking for markup tags, return immediately as soon a single one is
        found.

2008-05-28  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
        original, unscaled input values.  Confirmed by Greg Hitchcock from
        Microsoft.

2008-05-27  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/tohtml.py (block_footer_start,
        block_footer_middle): Beautify output.

2008-05-25  Werner Lemberg  <wl@gnu.org>

        * src/raster/ftraster.c (fc_black_render): Return 0 when we are
        trying to render into a zero-width/height bitmap, not an error code.

        * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
        of the graphics state for subglyphs to...
        (TT_Hint_Glyph): This function.
        Hinting instructions for a composite glyph apparently refer to the
        just hinted subglyphs, not the unhinted, unscaled outline.  This
        seems to fix Savannah bugs #20973 and (at least partially) #23310.

2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

        proposed by an anonymous reporter of Savannah bug #23204.

2008-05-18  Werner Lemberg  <wl@gnu.org>

        * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
        correction for pixel boundary.  Without this patch, the effect can
        be cumulative under certain circumstances, making glyphs taller and
        taller after each call.  This fixes Savannah bug #19976.

2008-05-18  Werner Lemberg  <wl@gnu.org>

        * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
        This fixes Savannah bug #23280.

        * docs/CHANGES: Updated.

2008-05-18  David Turner <david@freetype.org>

        * src/psnames/psmodule.c (ft_wgl_extra_unicodes,
        ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
        ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
        declarations non-global.

        * src/type1/t1load.c: Add missing comment.

2008-05-17  Sam Hocevar  <samh>

        * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
        glyphs correctly.  Patch from Savannah bug #23277.

2008-05-16  Werner Lemberg  <wl@gnu.org>

        * docs/CHANGES: Updated.

2008-05-16  Sergey Tolstov  <stolstov@esri.com>

        Improve support for WGL4 encoded fonts.

        * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
        (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
        ft_wgl_extra_glyph_name_offsets): New arrays.
        (ps_check_wgl_name, ps_check_wgl_unicode): New functions.
        (ps_unicodes_init): Use them to add additional Unicode mappings.

2008-05-15  Werner Lemberg  <wl@gnu.org>

        * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
        <op_closepath>: `closepath' without a path is a no-op, not an error
        (cf. the PS reference manual).

        Reported by Martin McBride.

2008-05-15  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.

2008-05-15  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
        which contains a single but empty entry.  This is technically
        invalid (since it must end with `return'), but...

        Reported by Martin McBride.

2008-05-14  Werner Lemberg  <wl@gnu.org>

        Finish fix of scaling bug of CID-keyed CFF subfonts.

        * include/freetype/internal/ftcalc.h, src/base/ftcalc.c
        (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
        functions.

        * src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
        provide global hinting data for both the top-font and all subfonts
        (with proper scaling).

        * src/cff/cffobjs.c (cff_make_private_dict): New function, using
        code from `cff_size_init'.
        (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
        Use CFF_Internal and handle subfonts.
        (cff_face_init): Handle top-dict and subfont matrices correctly;
        apply some heuristic in case of unlikely matrix concatenation
        results.  This has been discussed with people from Adobe (thanks
        goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
        and not correct.

        * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

        * src/cff/cffgload.c (cff_builder_init): Updated.
        (cff_decoder_prepare): Handle hints globals for subfonts.
        Update all callers.
        (cff_slot_load): Handling scaling of subfonts properly.

        * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
        (cff_parse_font_matrix): Use it.

        * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
        FT_ULong.

        * docs/CHANGES: Document it.

2008-05-13  Werner Lemberg  <wl@gnu.org>

        * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
        Handle case `face_index < 0'.
        * docs/CHANGES: Document it.

2008-05-04  Werner Lemberg  <wl@gnu.org>

        First steps to fix the scaling bug of CID-keyed CFF subfonts,
        reported by Ding Li on 2008/03/28 on freetype-devel.

        * src/base/cff/cffparse.c (power_tens): New array.
        (cff_parse_real): Rewritten to introduce a fourth parameter which
        returns the `scaling' of the real number so that we have no
        precision loss.  This is not used yet.
        Update all callers.
        (cff_parse_fixed_thousand): Replace with...
        (cff_parse_fixed_scaled): This function.  Update all callers.

2008-05-03  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
        transformation since it recursively calls FT_Load_Glyph.  This fixes
        Savannah bug #23143.

2008-04-26  Werner Lemberg  <wl@gnu.org>

        * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'

        * src/psaux/psobjs.c (t1_builder_init): Updated.

        * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as
        obsolete since they aren't used.
        * src/cff/cffgload.c (cff_builder_init): Updated.

2008-04-14  Werner Lemberg  <wl@gnu.org>

        * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to
        `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZ'.  From Savannah
        bug #22909.

        * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
        integer part is zero.

2008-04-01  Werner Lemberg  <wl@gnu.org>

        Fix compilation with g++ 4.1 (with both `single' and `multi'
        targets).

        * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
        which is crossed by a `goto'.

        * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.

2008-03-31  Werner Lemberg  <wl@gnu.org>

        Fix support for subsetted CID-keyed CFFs.

        * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
        FT_IS_CID_KEYED): New macros.

        * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
        maximum CID value in CID-keyed CFFs.
        Handle FT_FACE_FLAG_CID_KEYED flag.

        * docs/CHANGES: Document it.


        Fix CFF font matrix calculation and improve precision.

        * src/cff/cffparse.c (cff_parse_real): Increase precision if integer
        part is zero.
        (cff_parse_font_matrix): Simplify computation of `units_per_em';
        this prevents overflow also.


        Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.

        * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'.  Patch from
        Savannah bug #22675.

2008-03-13  Derek Clegg  <dclegg@apple.com>

        * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop. 
        Patch from Savannah bug #22541.

2008-03-03  Masatoshi Kimura  <VYV03354@nifty.ne.jp>

        * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
        tt_cmap14_find_variant): Return correct value.
        (tt_cmap14_variant_chars): Fix check for `di'.

        Add build support for symbian platform.  From Savannah bug #22440.

        * builds/symbian/*: New files.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
        synthesis.  For any face of a specified FOND, always the name for
        the first face was used.  Except of a FOND that refers multiple
        Type1 font files, wrong synthesized font names are not used at all,
        so this is an invisible bug.  A few limit checks are added too.

        * builds/mac/ftmac.c: Ditto.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Split compiler option to link Carbon
        frameworks to one option for CoreServices framework and another
        option for ApplicationServices framework.  The split options can be
        managed by GNU libtool to avoid unrequired duplication when FreeType
        is linked with other applications.  Suggested by Daniel Macks,
        Savannah bug #22366.

2008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>

        * src/truetype/ttinterp.c (Ins_IUP): Check number of points.  Fix
        from Savannah bug #22356.

2008-02-17  Jonathan Blow  <jon@number-none.com>

        * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
        Check for valid callback pointers.

2008-02-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
        handle by its value instead of ResError(), fix provided by Deron
        Kazmaier.  According to the Resource Manager Reference,
        GetResource(), Get1Resource(), GetNamedResource(),
        Get1NamedResource() and RGetResource() set noErr but return NULL
        handle when they can not find the requested resource.  These
        functions never return undefined values, so it is sufficient to
        check if the handle is not NULL.

        * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

2008-02-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
        inclusion styles.  Now it always includes src/base/ftmac.c;
        builds/mac/ftmac.c is never included in any configuration.

        * builds/unix/configure.raw: Print warning if configure is executed
        with options to specify Carbon functionalities explicitly.

        * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
        included automatically and manual replacement is required.

2008-02-11  Werner Lemberg  <wl@gnu.org>

        * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
        (dos_setup), builds/freetype.mk (clean_project_dos,
        distclean_project_dos): Don't use \ but $(SEP).  Reported by Duncan
        Murdoch.

2008-01-18  Sylvain Pasche  <sylvain.pasche@gmail.com>

        * src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to

2008-01-10  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
        where the number of contours in a simple glyph is zero (and which
        does contain an entry in the `glyf' table).  This fixes Savannah bug
        #21990.

2008-01-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Formatting suggested by Sean McBride.

2007-12-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Improvement of POSIX resource-fork accessor to load unsorted
        references in a resource.  In HelveLTMM (resource-fork PostScript
        Type1 font bundled with Mac OS X since 10.3.x), the appearance order
        of PFB chunks is not sorted; sorting the chunks by reference IDs is
        required.

        * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
        type to store a pair of reference ID and offset to the chunk.

        * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
        sort FT_RFork_Ref by their reference IDs.

        (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
        sorted by reference ID.

2007-12-14  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
        division too early; otherwise the most significant digit(s) of the
        final result are lost as the value is truncated to an integer.  This
        fixes Savannah bug #21794 (where the patch has been posted too).

2007-12-06  Fix  <4d876b82@gmail.com>

        Pass options from one configure script to another as-is (not
        expanded).  This is needed for options like
        --includedir='${prefix}/include'.

        * builds/unix/detect.mk, configure: Prevent argument expansion in
        call to the (real) `configure' script.

2007-12-06  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
        TT_USE_BYTECODE_INTERPRETER isn't defined.

2007-12-06  Werner Lemberg  <wl@gnu.org>

        There exist CFFs which contain opcodes for the Type 1 operators
        `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
        However, it doesn't harm to support them.

        * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
        `cff_op_closepath.'
        (cff_argument_counts): Ditto.

        (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
        and 13 (hsbw) which are invalid in Type 2 charstrings.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
        support new pathname syntax `..namedfork/rsrc' to access a resource
        fork on Mac OS X.  The legacy syntax `/rsrc' does not work on
        case-sensitive HFS+.
        (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
        buffer size to store a pathname.
        * include/freetype/internal/ftrfork.h: Increment the number of
        resource fork guessing rule.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Improve the compile tests to search
        Carbon functions.
        * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
        proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        The documents and comments for Mac OS X are improved by Sean
        McBride.

        * docs/INSTALL.MAC: Improve English and add comment on lowest
        system version specified by MACOSX_DEPLOYMENT_TARGET.

2007-12-04  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
        concatenate error codes.
        * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.

2007-12-04  Graham Asher  <graham.asher@btinternet.com>

        * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
        concatenate error codes.

2007-12-04  Sean McBride  <sean@rogue-research.com>

        * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
        warning.

2007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
        not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
        cannot mmap() the specified file and cannot seek to head of the
        specified file, it returns NULL stream and FT_Open_New() returns the
        error immediately.  On MacOS, most legacy MacOS fonts fall into such
        a scenario because their data forks are zero-sized and cannot be
        sought.  To proceed to guessing of resource fork fonts, the
        functions for legacy MacOS font must properly handle the NULL stream
        returned by FT_New_Stream().

        * src/base/ftobjs.c (IsMacBinary): Return error
        FT_Err_Invalid_Stream_Operation immediately when NULL stream is
        passed.
        (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
        to fallback.  Originally, legacy MacOS font is tested in the cases
        of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
        or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
        .dfont header is combined).  Now the case of
        FT_Err_Cannot_Open_Stream is included.

        * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
        skip FT_Stream_Seek(), which seeks to the head of stream, and
        proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
        for a NULL stream causes a Bus error on Mac OS X.
        (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
        immediately if passed stream is NULL.
        (raccess_guess_apple_single): Ditto.

2007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Fix for Carbon incompatibilities since Mac OS X 10.5,
        proposed by Sean McBride.

        * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.

        * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
        FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
        Carbon functions from a forked process is classified as unsafe
        by Apple. All Carbon-dependent functions should be deprecated.

        * src/base/ftmac.c: Use essential header files <Carbon/Carbon.h>
        and <ApplicationServices/ApplicationServices.h> instead of
        all-in-one header file <CoreServices/CoreServices.h>.

        Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
        genuine macro PATH_MAX.

        Add fallback macro for kATSOptionFlagsUnRestrictedScope which
        is not found in Mac OS X 10.0.

        Multi-character constants ('POST', 'sfnt' etc) are replaced by
        64bit constants calculated by FT_MAKE_TAG() macro.

        For the index in the segment of resource fork, new portable
        type ResourceIndex is introduced for better compatibility.
        This type is since Mac OS X 10.5, so it is defined as short
        when built on older platforms.

        (FT_ATSFontGetFileReference): If build target is only the systems
        10.5 and newer, it calls Apple genuine ATSFontGetFileReference().

        (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
        and newer or 64bit platform, because legacy type FSSpec type is
        removed completely.

        (FT_New_Face_From_FSSpec): Ditto.

2007-11-01  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
        fixes Savannah bug #21485.

2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>

        * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
        can handle the font at all, then check `face_index'.  Otherwise, the
        driver might return the wrong error code.  This fixes Savannah bug
        #21468.

2007-10-21  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
        support for bit 8 of the `fsSelection' field in the `OS/2' table. 
        MS is already using this; hopefully, this becomes part of OpenType
        1.5.
        Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
        (WWS_SUBFAMILY).

2007-10-20  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
        Add `td.left' element to CSS.
        (toc_section_enter): Use it.

2007-10-18  David Turner  <david@freetype.org>

        * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
        functions related to cmap type 14 support to the
        `FT_Object_ActionName' scheme:

          FT_Get_Char_Variant_index     -> FT_Face_GetCharVariantIndex
          FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
          FT_Get_Variant_Selectors      -> FT_Face_GetVariantSelectors
          FT_Get_Variants_Of_Char       -> FT_Face_GetVariantsOfChar
          FT_Get_Chars_Of_Variant       -> FT_Face_GetCharsOfVariant

        Update documentation accordingly.

        * src/sfnt/ttcmap.c: Stronger cmap 14 validation.
        Make the code a little more consistent with FreeType coding
        conventions and modify the cmap14 functions that returned a newly
        allocated array to use a persistent vector from the TT_CMap14 object
        instead.

        (TT_CMap14Rec): Provide array and auxiliary data for result.
        (tt_cmap14_done, tt_cmap14_ensure): New functions.

        (tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary,

2007-10-01  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (find_unicode_charmap): If search for a UCS-4
        charmap fails, do the loop again while searching a UCS-2 charmap.
        This favours MS charmaps over Apple ones.

2007-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c: Introduction of abstract `short' data types,
        ResFileRefNum and ResID.  These types were introduced for Copland,
        then backported to MPW.  The variables exchanged with FileManager
        QuickDraw frameworks are redefined by these data types.  Patch was
        proposed by Sean McBride.

        * Version 2.3.3 released.
        =========================


        Tag sources with `VER-2-3-3'.

        * docs/CHANGES: Mention CVE-2007-1351.

2007-04-03  David Turner  <david@freetype.org>

        * src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,
        if one of the resolution values is 0, treat it as if it were the
        same as the other value.

2007-04-02  David Turner  <david@freetype.org>

        Add special code to detect `extra-light' fonts and do not snap their
        stem widths too much to avoid bizarre hinting effects.

        * src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
        `extra_light' members.

        * src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize

        padding.

2007-03-28  Werner Lemberg  <wl@gnu.org>

        * src/bdf/bdflib.c (setsbit, sbitset): Handle values >= 128
        gracefully.
        (_bdf_set_default_spacing): Increase `name' buffer size to 256 and
        issue an error for longer names.  This fixes CVE-2007-1351.
        (_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
        number of code points in Unicode.

        * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
        computations in order to ignore single-point contours.  These are
        never rasterized and correspond in certain fonts to mark-attach
        points that are very far from the glyph's real outline, ruining the
        computation.

        * src/autofit/afloader.c (af_loader_load_g): In the case of
        monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.
        Otherwise code that uses them will most certainly ruin the fixed
        advance property.

        * docs/CHANGES, docs/VERSION.DLL, README, Jamfile (RefDoc): Update
        documentation and bump version number to 2.3.3.

        Introduce __attribute((deprecated))__ to warn functions
        which use non-ANSI data types in its interfaces.
        (FT_GetFile_From_Mac_Name): Deprecated, using FSSpec.
        (FT_GetFile_From_Mac_ATS_Name): Deprecated, using FSSpec.
        (FT_New_Face_From_FSSpec): Deprecated, using FSSpec.
        (FT_New_Face_From_FSRef): Deprecated, using FSRef.

        * src/base/ftmac.c: Predefine FT_DEPRECATED_ATTRIBUTE as void
        to avoid warning in building FreeType.
        * builds/mac/ftmac.c: Ditto.

2007-02-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftbase.c: Fix to use builds/mac/ftmac.c, if configured
        `--with-fsspec' etc.  Replace #include "ftmac.c" with
        #include <ftmac.c>.

2007-02-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * include/freetype/ftmac.h (FT_GetFilePath_From_Mac_ATS_Name):

        FT_GetFile_From_Mac_Name, FT_GetFile_From_Mac_ATS_Name are
        for passing to FT_New_Face_From_FSSpec.

2007-02-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * Version 2.3.1 released.
        =========================


        Tag sources with `VER-2-3-1-FINAL'.

        * builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj: s/230/231/.
        * builds/win32/visualc/index.html: s/221/231/.

        * vms_make.com: Add `ftgasp'.

2007-01-30  David Turner  <david@freetype.org>

        Tag sources with VER-2-3-1 to prepare release.

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.

        * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
        s/2.3.0/2.3.1/.

        * builds/unix/configure.raw (version_info): Set to 9:12:3.


        * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
        (af_loader_load_g): Disable the warper (i.e., the light hinting
        improvements) to make a 2.3.1 bugfix release before introducing a
        new feature.  This should give us more time to tune and improve the
        warper for the next release.

        * docs/CHANGES: Update accordingly.

2007-01-25  David Turner  <david@freetype.org>

        For light auto-hinting, improve glyph advance widths and resurrect
        normal/full hinting to its normal quality.

        * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
        and `xmax_delta'.
        * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
        and `xmax_delta'.

        * src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
        preprocessor conditional with if-clause, handling both light and
        normal mode.

        * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
        (af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

2007-01-25  Werner Lemberg  <wl@gnu.org>

        * docs/release: Updated -- Savannah uses a new uploading scheme.

2007-01-25  David Turner  <david@freetype.org>

        * src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.

        * src/cff/cffgload.c (cff_decoder_parse_charstrings)
        <cff_op_callsubr, cff_op_callgsubr>: Fix sanity check for empty
        functions.

        * docs/CHANGES: Document light auto-hinting improvement.

2007-01-25  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
        correctly in a sanity check.  Since this function is only used to
        load local and global functions, any charstring that called the last
        local/global function would fail otherwise.  This fixes Savannah bug
        #18867.

        * docs/CHANGES: Document it.

2007-01-23  David Turner  <david@freetype.org>

        * src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
        prevented compilation when disabling both the unpatented and the
        bytecode interpreter in the TrueType font driver.


        Fix and enable the warper to improve `light' hinting mode.  This is
        not necessarily a final version, but it seems to work well.

        * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
        Disable code.
        (af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
        * src/autofit/aftypes.h: Activate AF_USE_WARPER.

        * src/autofit/afwarp.c (AF_WarpScore): Tune table.
        (af_warper_compute_line_best): Fix array size of `scores'.
        (af_warper_compute): Better handling of border cases.
        * src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
        and `X2'.

2007-01-21  Werner Lemberg  <wl@gnu.org>

        * ChangeLog: Split off older entries into...
        * ChangeLog.22: This new file.

2007-01-21  Werner Lemberg  <wl@gnu.org>

        * docs/CHANGES: Document SHZ fix.

2007-01-21  George Williams  <gww@silcom.com>

        * src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
        points.

2007-01-21  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/ttmtx.c (tt_face_get_metrics)
        [!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.

2007-01-17  Werner Lemberg  <wl@gnu.org>

        (tt_face_init), src/truetype/ttinterp.c (Ins_SHC): Fix compiler
        warnings.

        * builds/amiga/include/freetype/config/ftconfig.h: Synchronize.

2007-01-14  Detlef Würkner  <TetiSoft@apg.lahn.de>

        Fix various compiler warnings.

        src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly
        uninitialized variables.

2007-01-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * docs/CHANGES, docs/INSTALL.MAC: Improvements.

2007-01-13  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1afm.c (T1_Read_Metrics): MS Windows allows PFM
        versions up to 0x3FF without complaining.

2007-01-13  Derek Clegg  <dclegg@apple.com>

        Add FT_Get_PS_Font_Info interface to CFF driver.

        * src/cff/cfftypes.h: Include FT_TYPE1_TABLES_H.
        (CFF_FontRec): Add `font_info' field.

        * src/cff/cffload.c: Include FT_TYPE1_TABLES_H.
        (cff_font_done): Free font->font_info if necessary.

        * src/cff/cffdrvr.c (cff_ps_get_font_info): New function.
        (cff_service_ps_info): Register cff_ps_get_font_info.

2007-01-13  Werner Lemberg  <wl@gnu.org>

        * src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix compilation
        with C++ compiler.

        * src/autofit/afhints.c (af_glyph_hints_dump_segments,
        af_glyph_hints_dump_edges): Ditto.

        * src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
        `modules.cfg').

        * src/sfnt/ttsbit0.h: Remove.

        * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.

2007-01-12  David Turner  <david@freetype.org>

        * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
        bug in the bitmap emboldener if the pitch of the source bitmap is
        much larger than its width.

        * src/truetype/ttinterp.c (Update_Max): Fix aliasing-related
        compilation warning.

2007-01-12  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
        crash with some Mac OS X .dfont files.  Submitted by Masatake
        Yamato.

        * autogen.sh: Small fix to get it working on Mac OS X properly:
        The issue is that GNU libtool is called `glibtool' on this platform,
        and we must call `glibtoolize', since `libtoolize' doesn't exist.

2007-01-10  David Turner  <david@freetype.org>

        * all-sources: Tag all sources with VER-2-3-0-RC1 and
        VER-2-3-0.

        * src/type1/t1load.c (T1_Get_MM_Var): Always return fixed point
        values.

2007-01-08  David Turner  <david@freetype.org>

        * docs/CHANGES: Updated.

        * include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add
        a new API `FT_Get_Gasp' to return entries of the `gasp' table
        corresponding to a given character pixel size.

        * src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
        `gasp' table, in order to avoid potential problems with later
        versions.

        * include/freetype/config/ftheader.h (FT_GASP_H): New macro for
        <freetype/ftgasp.h>.

        * src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),
        modules.cfg (BASE_EXTENSIONS), builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj: Add src/base/ftgasp.c to the
        default build.

2007-01-07  Werner Lemberg  <wl@gnu.org>

        * src/cid/cidparse.c (cid_parser_new): Improve error message for
        Type 11 fonts.
        Scan for `/sfnts' token.

2007-01-07  Werner Lemberg  <wl@gnu.org>

        * src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.

2007-01-06  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_index_init): Remove unused variable.
        (cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

2007-01-04  David Turner  <david@freetype.org>

        * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
        correctly.  This fixes Savannah bug #17876.


        Do not allocate interpreter-specific tables in memory if we are not
        going to load glyphs with the bytecode interpreter anyway.

        * src/truetype/ttgload.c (tt_loader_init): Load execution context
        only if glyph is hinted.
        Updated.
        * src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
        and `cvs_ready'.
        Add `tt_size_ready_bytecode' declaration.
        * src/truetype/ttobjs.c (tt_size_done_bytecode,
        tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
        (tt_size_init): Move most code into `tt_size_init_bytecode'.
        (tt_size_done): Move most code into `tt_size_done_bytecode'.
        (tt_size_reset): Move some code to `tt_size_ready_bytecode'.


        Don't extract the metrics table from the SFNT font file.  Instead,
        reparse it on each glyph load.  The runtime difference is not
        noticeable, and it can save a lot of heap memory when memory-mapped
        files are not used.

        * include/freetype/internal/tttypes.h (TT_FaceRec): Add members
        `horz_metrics_offset' and `vert_metrics_ofset'.
        * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
        Updated.


        * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.


        Do not load the CFF index offsets into memory, since this wastes a
        *lot* of heap memory with large Asian CFF fonts.  There is no
        significant performance loss.

        * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
        * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
        `data_size'.
        (CFF_CharsetRec): Add field `num_glyphs'.

        * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
        cff_charset_cid_to_gindex): New functions.
        (cff_new_index): Renamed to...
        (cff_index_init): This.  Update all callers.
        Updated -- some code has been moved to `cff_index_load_offsets'.
        (cff_done_index): Renamed to...
        (cff_index_done): This.  Update all callers.
        (cff_index_get_pointers, cff_index_access_element): Updated to use
        stream offsets.
        (cff_charset_compute_cids): Set `num_glyphs' field.
        (cff_encoding_load): Updated.

        * src/cff/cffgload.c (cff_slot_load): Updated.

2007-01-04  David Turner  <david@freetype.org>

        * docs/INSTALL.UNIX: Simplify some parts, add reference to
        autogen.sh and pointer to README.CVS.

        * README.CVS: Add common problem description and solution
        when running autogen.sh.

        * docs/INSTALL: Add reference to MacOS X.

        * docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

        * docs/TODO: Remove obsolete items.

        * src/raster/ftraster.c: (TRaster_Instance): Replace it with...
        (TWorker): This.
        Remove `count_table' and `memory'.
        Make `grays' a pointer.
        (TRaster): New structure.
        (count_table): New static array.
        (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
        Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
        ft_black_set_mode, ft_black_render): Updated.
        (ft_black_init): Don't initialize `count_table'.
        (ft_black_reset): Use the render pool.  This saves about 6KB of
        heap space for each FT_Library instance.

        * src/smooth/ftgrays.c (TRaster): Replaced with...
        (TWorker): This.
        Remove `memory'.
        (TRaster): New structure.

        (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
        gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
        gray_render_span, gray_raster_render): Updated.
        (gray_raster_reset): Use the render pool.  This saves about 6KB of
        heap space for each FT_Library instance.

        * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
        src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
        src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
        FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
        the optimization is no longer experimental.

        * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
        Remove a typo that results in no hinting and a memory leak with some
        large Asian CFF fonts.

        * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
        which happens when FT_Done_Library is called with still opened
        CFF_Faces in it.  We need to close all faces before destroying the
        modules, or else some bad things (memory leaks) may happen.

2007-01-02  Werner Lemberg  <wl@gnu.org>

        * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
        Remove compiler warning.

2007-01-02  David Turner  <david@freetype.org>

        `gxv_kern_subtable_fmt0_pairs_validate'.

2006-12-22  David Turner  <david@freetype.org>

        * src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
        warnings.

        * builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
        to avoid deprecation warnings with Visual C++ 8.

          http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c: Specialized for Mac OS X only.
        * builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
        * builds/unix/configure.raw: Ditto. When explicit switches for
        FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
        builds/mac/ftmac.c is used instead of default src/base/ftmac.c.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
        * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
        instead of src/base/ftmac.c
        * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.

        POSIX, cf.
          http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
        (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
        format or .dfont, to simulate the face index number counted by ftmac.c.
        (IsMacResource): Return the number of scalable faces correctly.

2006-12-10  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (version): Protect against `distclean' target.

2006-12-09  Werner Lemberg  <wl@gnu.org>

        * builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'
        or `type'.

        * builds/freetype.mk (version): Extracted from freetype.h, using
        GNU make's built-in string functions.
        (refdoc): Use $(version) instead of static version number.

2006-12-08  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (dist): Extract version number from freetype.h.

2006-12-08  Vladimir Volovich  <vvv@vsu.ru>

        * src/tools/apinames (State): Remove final comma in structure -- xlc
        v5 under AIX 4.3 doesn't like this.

2006-12-07  David Turner  <david@freetype.org>

        * src/autofit/afloader.c (af_loader_load_g): Small adjustment
        to the spacing of auto-fitted glyphs.  This only impacts rare
        cases (e.g., Arial Bold at rather small character sizes).

2006-12-03  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.

2006-12-01  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are

        * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.

        * src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType
        ones instead.

        * src/autofit/afhints.c (af_glyph_hints_dump_segments): Remove unused
        variable.

2006-11-26  Pierre Hanser  <hanser@club-internet.fr>

2006-11-25  David Turner  <david@freetype.org>

        * src/autofit/afhints.c (af_glyph_hints_dump_points,
        af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
        Add stubs to link the `ftgrid' test program when debugging is
        disabled in the auto-hinter.

2006-11-23  David Turner  <david@freetype.org>

        * src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,
        src/autofit/aftypes.h: Miscellaneous auto-hinter improvements.

        * src/autofit/afhints.c (af_glyph_hints_dump_segments) [AF_DEBUG]:
        Emit more sensible information.

        Improve handling of remaining edges.

2006-11-22  Werner Lemberg  <wl@gnu.org>

        Fix Savannah bug #15553.

        * src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
        program after a change from mono to grayscaling (and vice versa).
        Use correct constant for comparison to get `exec->grayscale'.

2006-11-18  Werner Lemberg  <wl@gnu.org>

        Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
        test for a valid glyph index must be deferred to the font drivers.
        This patch fixes Savannah bug #18301.

        * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
        * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
        (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
        src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
        (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
        src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
        (FNT_Load_Glyph): Check validity of `glyph_index'.

2006-11-13  David Turner  <david@freetype.org>

        * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
        `enhancements' are still too buggy for general use.

        * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
        FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
        when building the library to change the default LCD filter to be
        used.  This is only useful for experimentation.

        * include/freetype/ftlcdfil.h: Update documentation.

2006-11-10  David Turner  <david@freetype.org>

        * src/smooth/ftsmooth.c: API change for the LCD
        filter.  The FT_LcdFilter value is an enumeration describing which
        filter to apply, with new values FT_LCD_FILTER_LIGHT and
        FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
        algorithm which produces strong color fringes for everything
        except very-well hinted text).

        * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
        second parameter to an enum type.

        (FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.
        (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering
        callback and update other fields.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic)
        [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
        Other minor improvements.

        * src/autofit/aflatin.c: Various tiny improvements that drastically
        improve the handling of serif fonts and of LCD/LCD_V hinting modes.
        (af_latin_hints_compute_edges): Fix typo.
        (af_latin_compute_stem_width): Take better care of diagonal stems.

        typo which created a variable-used-before-initialized bug.

2006-11-07  Zhe Su  <james.su@gmail.com>

        * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
        also.

2006-11-03  Werner Lemberg  <wl@gnu.org>

        * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

2006-11-02  David Turner  <david@freetype.org>

        Add a few tweaks to better handle serif fonts.
        Add more debugging messages.

        * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
        segments that are less than 1.5 pixels high.  This gets rid of
        *many* corner cases with serifs.
        (af_latin_align_linked_edge): Add logging message.
        (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
        Add logging messages.
        Handle AF_EDGE_FLAG flag specially.

        * src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
        _af_debug_disable_blue_hints, and _af_debug_hints variables.

        * src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
        Update external declarations.
        (af_corner_orientation, af_corner_is_flat): Replaced by...

        ft_corner_is_flat): These declarations.

        * src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
        Comment out.  Replaced by...

        * src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
        These functions.  Update all callers.
        (FT_Add64) [!FT_LONG64]: Simplify.

        * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
        (af_direction_compute): Add a missing FT_ABS call.  This bug caused
        production of garbage by missing lots of segments.

        * src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.

        * src/autofit/afloader.c (af_loader_init, af_loader_done)
        [AF_DEBUG]: Set _af_debug_hints.


        * src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H.

        * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
        better deal with broken Asian fonts with strange glyphs, having
        self-intersections and other peculiarities.  The used algorithm is
        based on the nonzero winding rule.

2006-10-23  David Turner  <david@freetype.org>

        Speed up the CFF font loader.  With some large CFF fonts,
        FT_Open_Face is now more than three times faster.

        * src/cff/cffload.c (cff_get_offset): Removed.
        (cff_new_index): Inline functionality of `cff_get_offset'.
        (cff_charset_compute_cids, cff_charset_free_cids): New functions.
        (cff_charset_done): Call `cff_charset_free_cids'.
        (cff_charset_load): Call `cff_charset_compute_cids'.
        (cff_encoding_load) <Populate>: Ditto, to replace inefficient loop.

        * src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
        with FT_NEXT_XXX.


        Speed up the Postscript hinter, with more than 100% speed increase
        on my machine.

        * src/pshinter/pshalgo.c (psh_corner_is_flat,
        psh_corner_orientation): New functions.
        (psh_glyph_compute_inflections): Merge loops for efficiency.
        Use `psh_corner_orientation'.

        (psh_hint_table_find_strong_point): Renamed to...
        (psh_hint_table_find_strong_points): This.
        Rewrite, adding argument to handle all points at once.
        Update all callers.
        (PSH_MAX_STRONG_INTERNAL): New macro.
        (psh_glyph_interpolate_normal_points): Rewrite for efficiency.

2006-10-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_FOND): Initialize variable
        `error' with FT_Err_Ok.

2006-10-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * docs/INSTALL.CROSS: New document file for cross-building.

        * builds/unix/configure.raw: Preliminary cross-building support.
        Find native C compiler and pass it by CC_BUILD, and
        find suffix for native executable and pass it by EXEEXT_BUILD.
        Also suffix for target executable is passed by EXEEXT.

        * builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
        build `apinames' which runs on building system.  They are set by
        CC_BUILD and EXEEXT_BUILD.

        * builds/exports.mk (APINAMES_EXE): Change the extension for
        apinames from the suffix for target (E) to that for building host
        (E_BUILD).

2006-10-12  Werner Lemberg  <wl@gnu.org>

        * docs/INSTALL.UNX, docs/UPGRADE.UNX: Renamed to...
        * docs/INSTALL.UNIX, docs/UPGRADE.UNIX: This.  Update all documents
        which reference those files.

2006-10-12  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw (FT2_EXTRA_LIBS): New variable.  It is
        embedded in freetype2.pc and freetype-config.  Use it to record
        Carbon dependency of MacOSX.

        * builds/unix/freetype2.in: Embed FT2_EXTRA_LIBS.

        * builds/unix/freetype-config.in: Ditto.

        * include/freetype/internal/ftobjs.h (FT_Face_InternalRec):
        s/unpatented_hinting/ignore_unpatented_hinter/.
        Update all callers.

        * src/base/ftobjs.c (FT_Load_Glyph): Refine the algorithm whether
        auto-hinting shall be used or not.

        * include/freetype/internal/ftobjs.h (FT_Face_InternalRec):
        s/force_autohint/unpatented_hinting/.  Update all callers.

        * src/base/ftobjs.c (FT_Load_Glyph): Updated code.

        * src/autofit/aftypes.h (AF_DEBUG): Undefine to get rid of traces.

2006-09-27  David Turner  <david@freetype.org>

        * include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.


        Add a new API to support color filtering of subpixel glyph bitmaps.
        In a default build, the function `FT_Library_SetLcdFilter' returns
        `FT_Err_Unimplemented_Feature'; you need to #define
        FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
        real implementation.

        * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

        * include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
        typedef.
        (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
        `lcd_filter_weights' and `lcd_filter'.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
        `hmul' and `vmul'.

        Handle subpixel rendering.
        Simplify function.
        (ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
        (ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.

        * include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
        pointing to <freetype/ftlcdfil.h>.

        * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
        vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

        * modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.

2006-09-26  David Bustin

        * src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes
        correctly.  Reported as Savannah bug #17843.

2006-09-26  David Turner  <david@freetype.org>

        * src/autofit/afhints.h (AF_HINTS_DO_HORIZONTAL,
        AF_HINTS_DO_VERTICAL, AF_HINTS_DO_ADVANCE): New macros to disable
        horizontal and vertical hinting for the purpose of debugging the
        auto-fitter.

        * src/autofit/afmodule.c (_af_debug_disable_horz_hints,
        _af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.

        * src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.

        * include/freetype/config/ftoption.h, devel/ftoption.h
        (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
        we want to compile LCD-optimized rendering code (à la ClearType) or
        not.  The macro *must* be disabled in default builds of the library
        for patent reasons.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
        LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
        isn't defined at compile time.  This only changes the content of the
        rendered glyph to match the one of normal gray-level rendering,
        hence clients should not need to be modified.

2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>

        The Type 1 parser now skips over top-level procedures as required
        for a `Simplified Parser'.  This makes the parser more robust as it
        doesn't poke around in PostScript code.  Additionally, it makes the
        FontDirectory hackery in src/type1/t1load.c unnecessary.

        * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
        (skip_literal_string): Add FT_Error as return value.

        (ps_parser_skip_PS_token): Handle procedures.
        Update code.

        Public API of TrueTypeGX, OpenType, and classic kern table validator
        should return `FT_Err_Unimplemented_Feature' if validation service
        is unavailable (disabled in `modules.cfg').  It is originally
        suggested by David Turner, cf.
        http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

        * src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
        FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
        unavailable.
        (FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
        classic kern table validation service is unavailable.

        * src/base/ftotval.c (FT_OpenType_Validate): Return
        FT_Err_Unimplemented_Feature if OpenType validation service is
        unavailable.

        * src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of
        errors.

2006-06-07  David Turner  <david@freetype.org>

        * src/type1/t1afm.c (KERN_INDEX): Make it more robust.
        (T1_Read_Metrics): Fix memory leak which happened when the metrics
        file doesn't have kerning pairs.  This fixes Savannah bug #16768.

2006-06-06  David Turner  <david@freetype.org>

        Fix memory leak described in Savannah bug #16759.

        We change `ps_unicodes_init' so that it also takes a
        `free_glyph_name' callback to release the glyph names returned by
        `get_glyph_name'

        * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
        Renamed to ...
        (PS_GetGlyphNameFunc): This.
        (PS_FreeGlyphNameFunc): New typedef.
        (PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.

        * src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
        argument.
        (cff_sid_free_glyph_name): New function.
        (cff_cmap_unicode_init): Updated.

        * src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.

        * src/psnames/psmodule.c (ps_unicodes_init): Add variable for
        PS_FreeGlyphNameFunc and use it.


2006-06-04  David Turner  <david@freetype.org>

        * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
        `item_size == 0' as well -- though this sounds weird, it can
        theoretically happen.  This fixes Savannah bug #16669.

        * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
        of `face->num_glyphs' which missed the last glyph, due to
        the offset-by-1 computation, since the PFR format doesn't
        guarantee that glyph index 0 corresponds to the `missing
        glyph.  This fixes Savannah bug #16668.

2006-05-25  Werner Lemberg  <wl@gnu.org>

        * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
        `-no-undefined'.  Reported by Christian Biesinger.

2006-05-19  Brian Weed  <bw@imaginengine.com>

        * builds/win32/visualc/freetype.dsp: Release libraries no longer
        have debug information, and debug libraries use `C7 compatible'
        debug info.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Apply patch by Derek Clegg to fix two memory leaks in the MacOS
        resource fork handler.  This fixes Savannah bug #16631.

        * src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
        `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

        * src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):
        Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * build/unix/configure.raw: Add a fallback to disable Carbon
        dependency, if configured with no options on Mac OS X.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
        its content cannot be parsed as supported font.  This fixes
        the second part of Savannah bug #16590.

2006-05-18  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (TT_Load_Composite_Glyph)
        [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

2006-05-17  David Turner  <david@freetype.org>

        This is a major patch used to drastically improve the performance of
        loading glyphs.  This both speeds up loading the glyph vectors
        themselves and the auto-fitter module.

        We now use inline assembler code with GCC to implement `FT_MulFix',
        which is probably the most important function related to the
        engine's performance.

        The resulting speed-up is about 25%.


        * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
        `cursor' and `limit'.

        * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
        New functions.
        (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
        [TEST]: Remove.

        * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
        code.

        * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
        `FT_ZERO'
        (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
        (af_glyph_hints_reload: Rewrite recognition of weak points.

        * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
        constant values out of the loops.

        * src/autofit/aftypes.h: Updated.

        * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

        * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
        product to get orientation.

        * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
        (FT_Stream_OpenGzip): Use it to handle small files directly in
        memory.

        * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
        Improve performance.

        * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
        `limit'.

        (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
        TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
        exceedingly large values of number of contours.  Speed up by
        reducing the number of loops.

        * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.


        * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
        used to detect rogue clients from 4 to 16.  This is to prevent some
        segmentation faults with fonts like `KozMinProVI-Regular.otf' which
        comes from the Japanese Adobe Reader Asian Font pack.

2007-05-17  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
        fixes the first part of Savannah bug #16590.

2006-05-16  Werner Lemberg  <wl@gnu.org>

        * docs/PROBLEMS: Updated icl issues.
