Problem reported by Tobias Wolf <towolf@gmail.com>.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)

Fix Savannah bug #30373.
Too serious check of errors by `FT_CMap_New' since 2010-07-04
is fixed. Reported by Tor Andersson.
* include/freetype/fterrdef.h

indicate the Unicode charmap synthesis failed because
no Unicode glyph name is found.
* src/psnames/psmodule.c (ps_unicodes_init): Return
PSnames_Err_No_Unicode_Glyph_Name when no Unicode glyph name
is found in the font.
* src/cff/cffcmap.c (cff_cmap_unicode_init): Return

2010-07-05 Werner Lemberg <wl@gnu.org>
[cff] Next try to fix `hintmask' and `cntrmask' limit check.
Problem reported by malc <av1474@comtv.ru>.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)
<cff_op_hintmask>: It is possible that there is just a single byte
after the `hintmask' or `cntrmask', e.g., a `return' instruction.
2010-07-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Restrict the number of the charmaps in a rogue-compatible mode.
Fix for Savannah bug #30059.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).
* src/cff/cffobjs.c (cff_face_init): Abort the automatic
selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message
when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/base/ftobjs.c (find_unicode_charmap): When Unicode charmap
is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search
earlier one.
(find_variant_selector_charmap): When UVS charmap is found after
FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.
2010-07-04 Werner Lemberg <wl@gnu.org>
TrueType hinting is no longer patented.
* include/freetype/config/ftoption.h, devel/ftoption.h
(TT_CONFIG_OPTION_BYTECODE_INTERPRETER): Define.
(TT_CONFIG_OPTION_UNPATENTED_HINTING): Undefine.
* docs/CHANGES, docs/INSTALL, include/freetype/freetype.h: Updated.
* docs/TRUETYPE, docs/PATENTS: Removed.
2010-07-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Check error value by `FT_CMap_New'.
* src/cff/cffobjs.c (cff_face_init): Check error value by
`FT_CMap_New'.
* src/pfr/pfrobjs.c (pfr_face_init): Ditto.
* src/type1/t1jobjs.c (T1_Face_Init): Ditto.
* src/type42/t42jobjs.c (T42_Face_Init): Ditto.
2010-07-03 Werner Lemberg <wl@gnu.org>

(FT_INT_MAX, FT_PtrDist)[_STANDALONE_]: Define.
2010-07-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Additional fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
POST fragment is 0, the segment is completely ignored. The declared
length of the segment is not cared at all. According to Adobe
Technical Note 5040, type 0 segment is a comment only and should not
be loaded for the interpreter. Reported by Robert Święcki.
2010-07-01 Werner Lemberg <wl@gnu.org>
[truetype] Protect against code range underflow.
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF): Don't allow
negative IP values.
2010-07-01 Werner Lemberg <wl@gnu.org>
[truetype] Add rudimentary tracing for bytecode instructions.

Fix Savannah bug #30263.

int' to avoid integer overflow.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller
threshold values for `width' and `height'. This is not directly
related to the bug fix but makes sense anyway.
2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Initial fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the
length of fragment declared in the POST fragment header, and prevent
an underflow in length calculation. Some fonts set the length to
zero in spite of the existence of a following 16bit `type'.
Reported by Robert Święcki.
2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Additional fix for Savannah bug #30248 and #30249.
* src/base/ftobjs.c (Mac_Read_POST_Resource): Check the buffer size
during gathering PFB fragments embedded in LaserWriter PS font for

[cff] Protect against invalid `hintmask' and `cntrmask' operators.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)
<cff_op_hintmask>: Ensure that we don't exceed `limit' while parsing
the bit masks of the `hintmask' and `cntrmask' operators.
2010-06-26 Werner Lemberg <wl@gnu.org>

if the frame size is larger than the stream size.
* src/base/ftsystem.c (ft_ansi_stream_io): Exit with error if
seeking a position larger than the stream size.

Properly mask AF_DIGIT bit in comparison.
2010-06-11 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30106.
Point numbers for FreeType's implementation of hinting masks are
collected before the final number of points of a glyph has been
determined; in particular, the code for handling the `endchar'
opcode can reduce the number of points.
* src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that

(cff_face_init): Use it to adjust `cffface->family_name'.
2010-05-20 Werner Lemberg <wl@gnu.org>

Information provided by Alan Coopersmith
<alan.coopersmith@oracle.com>.
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.
