+
+ [cache] Fix Savannah bug #27441, clean up Redhat bugzilla #513582.
+ Tricky casts in FTC_{CACHE,GCACHE,MRULIST}_LOOKUP_CMP() are removed.
+ Now these functions should be called with FTC_Node or FTC_MruNode
+ variable, and the caller should cast them to appropriate pointers to
+ concrete data. These tricky casts can GCC-4.4 optimizer (-O2)
+ confused and the crashing binaries are generated.
+
+ * src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast.
+ Now the 4th argument `node' of this function should be typed as
+ FTC_MruNode.
+
+ * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline
+ implementation, new temporal variable FTC_MruNode `_mrunode' to take
+ the pointer from FTC_MRULIST_LOOKUP_CMP(). For non-inline
+ implementation, tricky cast is dropped.
+
+ * src/cache/ftcmanag.c (FTC_SIZE_NODE): New macro casting
+ to FTC_SizeNode.
+ (FTC_Manager_LookupSize): Replace FTC_SizeNode `node' by FTC_MruNode
+ `mrunode', and FTC_SIZE_NODE() is inserted.
+ (FTC_FACE_NODE): New macro casting to FTC_FaceNode.
+ (FTC_Manager_LookupFace) Replace FTC_FaceNode `node' by FTC_MruNode
+ `mrunode', and FTC_FACE_NODE() is inserted.
+
+ * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Change the type of
+ `node' from FTC_INode to FTC_Node. Extra casting macro FTC_NODE()
+ is dropped.
+ (FTC_ImageCache_LookupScaler): Ditto.
+ (FTC_SBitCache_Lookup): Change the type of `node' from FTC_SNode to
+ FTC_Node. Extra casting macro FTC_NODE() is dropped. FTC_SNODE()
+ is inserted.

+
+ [BDF] Modify hash API to take size_t value instead of void *.
+
+ The hash API in BDF driver is designed to be generic, it takes
+ void * typed data. But BDF driver always gives an unsigned long
+ integer (the index to a property). To reduce non-essential
+ casts from unsigned long to void* and from void* to unsigned
+ long, the hash API is changed to take size_t integer.
+ The issue of incompatible cast between unsigned long and void*
+ on LLP64 platform is reported by NightStrike from MinGW-Win64
+ project. See
+ http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
+
+ * src/bdf/bdf.h: The type of hashnode->data is changed from
+ void* to size_t.
+
+ * src/bdf/bdflib.c (hash_insert): Get size_t data, instead of
+ void* data.
+ (bdf_create_property): Get the name length of new property by
+ size_t variable, with a cut-off at FT_ULONG_MAX.
+ (_bdf_set_default_spacing): Get the name length of the face by
+ size_t variable, with a cut-off at 256.
+ (bdf_get_property): Get the property id by size_t variable to
+ reduce the casts between 32-bit prop ID & hashnode->data during
+ simple copying.
+ (_bdf_add_property): Ditto.
+ (_bdf_parse_start): Calculate the index to the property array
+ by size_t variable.
+ (bdf_get_font_property): Drop a cast to unsigned long.

+
+ [Win64] Improve the computation of random seed from stack address.
+
+ On LLP64 platform, the conversion from pointer to FT_Fixed need
+ to drop higher 32-bit. Explict casts are required. Reported by
+ NightStrike from MinGW-w64 project. See
+ http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
+
+ * src/cff/cffgload.c: Convert the pointers to FT_Fixed explicitly.
+
+ * src/psaux/t1decode.c: Ditto.
+
+
+2009-09-03 Werner Lemberg <wl@gnu.org>
+
+ [raster] Improvements for stand-alone mode.
+
+ * src/raster/rules.mk: Don't handle ftmisc.h. It is needed for
+ stand-alone mode only.
+
+ * src/raster/ftmisc.h (FT_MemoryRec , FT_Alloc_Func, FT_Free_Func,
+ FT_Realloc_Func): Copy declarations from ftsystem.h.
+
+2009-09-02 Bram Tassyns <bramt@enfocus.be>
+
+ Improve vertical metrics calculation (Savannah bug #27364).
+
+ The calculation of `vertBearingX' is not defined in the OTF font
+ spec so FreeType does a `best effort' attempt. However, this value
+ is defined in the PDF and PostScript specs, and that algorithm is
+ better than the one FreeType currently uses:
+
+ FreeType: Use the middle of the bounding box as the X coordinate
+ of the vertical origin.
+
+ Adobe PDF spec: Use the middle of the horizontal advance vector as
+ the X coordinate of the vertical origin.
+
+ FreeType's algorithm goes wrong if you have a really small glyph
+ (like the full-width, circle-like dot at the end of the sentence, as
+ used in CJK scripts) with large bearings. With the FreeType
+ algorithm this dot gets centered on the baseline; with the PDF
+ algorithm it gets the correct location (in the top right). Note
+ that this is a serious issue, it's like printing the dot at the end
+ of a Roman sentence at the center of the textline instead of on the
+ baseline like it should. So i believe the PDF spec's algorithm
+ should be used in FreeType as well.
+
+ The `vertBearingY' value for such small glyphs is also very strange
+ if no `vmtx' information is present, since the height of the bbox is
+ not representable for the height of the glyph visually (the
+ whitespace up to the baseline is part of the glyph). The fix also
+ includes some code for a better estimate of `vertBearingY'.
+
+ * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
+ is now calculated as described by the Adobe PDF Spec. Estimate for
+ `vertBearingY' now works better for small glyphs completely above or
+ below the baseline into account.
+
+ * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
+ calculated as described by the Adobe PDF Spec. Vertical metrics
+ information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
+ was not defined.
+
+ * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
+ now calculated as described by the Adobe PDF Spec.
+
+2009-09-01 John Tytgat <John.Tytgat@esko.com>
+
+ Fix custom cmap for empty Type 1 font (Savannah bug #27294).
+
+ * include/freetype/internal/t1types.h (T1_EncodingRecRec_): Update
+ comment to reflect revised code_last meaning.
+ * src/type1/t1load.c (T1_Open_Face), src/type42/t42objs.c
+ (T42_Open_Face): Assign max_char as highest character code + 1 and
+ use this for T1_EncodingRecRec_::code_last.
+ * src/psaux/t1cmap.c (t1_cmap_custom_init): Follow revised
+ T1_EncodingRecRec_::code_last meaning.
+
+2009-08-25 Werner Lemberg <wl@gnu.org>
+
+ Fix rendering of horizontally compressed CFFs.

+ `font_matrix' also.
+
+ * docs/CHANGES: Updated.
+
+2009-08-03 suyu0925@gmail.com

+
+ * src/psaux/t1decode.c (t1_decoder_parse_charstrings):
+ Fix a few casts setting `value' from FT_Long to FT_Int32,
+ because `value' is typed as FT_Int32 since 2009-06-22.
+
+2009-07-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ sfnt: Fix a data type mismatching with its source.

+
+ smooth: Exclude 16-bit system in invalid pitch/height check.
+
+ * src/smooth/ftsmooth.c (ft_smooth_render_generic):

+ Use 16.16 format while parsing Type 1 charstrings.
+ This fixes Savannah bug #26867.
+
+ Previously, only integers have been used which can lead to serious
+ rounding errors.
+
+ However, fractional values are only used internally; after the
+ charstrings (of either Type 1 or 2) have been processed, the
+ resulting coordinates get rounded to integers currently -- before
+ applying scaling. This should be fixed; at the same time a new load
+ flag should be introduced, to be used in combination with
+ FT_LOAD_NO_SCALE, which indicates that font units are returned in
+ 16.16 format. Similarly, the incremental interface should be
+ extended to allow fractional values for metrics.

+
+ Fix B/W rasterization of subglyphs with different drop-out modes.
+
+ Normally, the SCANMODE instruction (if present) to set the drop-out
+ mode in a TrueType font is located in the `prep' table only and thus
+ valid for all glyphs. However, there are fonts like `pala.ttf'
+ which additionally contain this instruction in the hinting code of
+ some glyphs (but not all). As a result it can happen that a
+ composite glyph needs multiple drop-out modes for its subglyphs
+ since the rendering state gets reset for each subglyph.
+
+ FreeType collects the hinted outlines from all subglyphs, then it
+ sends the data to the rasterizer. It also sends the drop-out mode
+ -- after hinting has been applied -- and here is the error: It sends
+ the drop-out mode of the last subglyph only; drop-out modes of all
+ other subglyphs are lost.
+
+ This patch fixes the problem; it adds a second, alternative
+ mechanism to pass the drop-out mode: For each contour, the
+ rasterizer now checks the first `tags' array element. If bit 2 is
+ set, bits 5-7 contain the contour's drop-out mode, overriding the
+ global drop-out mode.
+
+ * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
+
+ * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
+ `tags[0]'.
+
+ * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
+ Use bits 3-5 instead of 0-2.
+ (New_Profile): Set the drop-out mode in the profile's `flags' field.
+ (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
+ necessary.
+ (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
+ Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
+ mode.
+
+2009-06-16 Werner Lemberg <wl@gnu.org>
+
+ Improve scan conversion rules 4 and 6.
+
+ Two new constraints are introduced to better identify a `stub' -- a
+ concept which is only vaguely described in the OpenType
+ specification. The old code was too rigorous and suppressed more
+ pixel than it should.
+
+ . The intersection of the two profiles with the scanline is less
+ than a half pixel. Code related to this was already present in
+ the sources but has been commented out.
+
+ . The endpoint of the original contour forming a profile has a
+ distance (`overshoot') less than half a pixel to the scanline.
+
+ Note that the two additional conditions fix almost all differences
+ to the Windows rasterizer, but some problematic cases remain.
+
+ * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
+ macros for the `flags' field in the `TProfile' structure.
+ (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
