+ [ftfuzzer] Add support for multiple files (patch #8779).

+ a constructed tarball should contain a font file as the first
+ element, and files to be attached as further elements.

+ [smooth] Faster alternative line renderer.

+ This implementation renders the entire line segment at once without

+
+ [sfnt] Improve handling of invalid SFNT table entries (#45987).
+
+ This patch fixes weaknesses in function `tt_face_load_font_dir'.
+
+ - It incorrectly assumed that valid tables are always at the
+ beginning. As a consequence, some valid tables after invalid
+ entries (which are ignored) were never seen.
+
+ - Duplicate table entries (this is, having the same tag) were not
+ rejected.
+
+ - The number of valid tables was sometimes too large, leading to
+ access of invalid tables.
+
+ * src/sfnt/ttload.c (check_table_dir): Add argument to return number
+ of valid tables.
+ Add another tracing message.
+ (tt_face_load_font_dir): Only allocate table array for valid

+
+ [autofit] Redesign code ranges (1/2).
+
+ This patch introduces auxiliary code ranges that identify no-base
+ characters; they refer to glyphs of a script that should be hinted
+ without alignments to blue zones (mostly diacritics).
+
+ It also splits off ranges for fallback scripts that handle subscript
+ and superscript characters not covered by OpenType features. For
+ example, this greatly helps improve the hinting of various phonetic
+ alphabets, which contain a large amount characters that look like
+ superscript glyphs.
+
+ Finally, code ranges are updated to Unicode 8.0, and enclosed
+ characters are removed in general since they normally look better if
+ they stay unhinted.
+
+ * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
+ 8.0.
+ Split off superscript-like and subscript-like glyphs into...
+
+ (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
+
+ (af_xxxx_nobase_uniranges): New arrays that hold no-base characters
+ of the corresponding character ranges.

+ Another adjustment to header locations.
+
+ This change is a result of a discussion thread on freetype-devel
+
+ http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html
+
+ Re-introduce the `freetype2' subdirectory for all FreeType header
+ files after installation, and rename the `freetype2' subdirectory in

+ * include/freetype: This.
+
+ * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
+ PRIVATE_HEADERS): Updated.
+ Update creation of `ftconfig.h'.
+ Install generated `ftconfig.h'.
+
+ * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

+
+ * builds/unix/freetype-config.in: Updated.
+ * builds/unix/configure.raw: Don't check for `rmdir'.
+ * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable
+ according to the autoconf info manual.
+ * builds/unix/install.mk (install, uninstall,

+
+ Fix Savannah bug #45097.
+
+ We no longer `pollute' the namespace of possible header file names;
+ instead we move `ft2build.h' up by one level so that it gets
+ installed in the default include directory (e.g.,
+ /usr/local/include). After this commit, only `ft2build.h' stays in
+ the compiler's include path.
+
+ No visible changes for the user who follows the standard FreeType
+ header inclusion rules.
+
+ * include/*: Move to ...
+ * include/freetype2/*: This directory, except `ft2build.h'.

+ Make Jam support work again.
+
+ This is just very basic stuff and just a little bit tested on

+
+ * Jamfile: Call `HDRMACRO' for `ftserv.h' also.
+ (DEFINES): Replace with...

+
+ * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is

+
+ [truetype] Fix memory leak.
+
+ Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+ http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+ there is an example code to trigger the bug.
+
+ * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'

+ years ago in version 2.4.3.
+
+2015-06-02 Werner Lemberg <wl@gnu.org>
+
+ [raster] Add more tracing.
+
+ * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
+ (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
+ Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
+
+2015-06-01 Werner Lemberg <wl@gnu.org>
+
+ [truetype] While tracing opcodes, show code position and stack.
+
+ * src/truetype/ttinterp.c: Change all existing TRACE7 calls to
+ TRACE6.
+ (opcode_name): Add string lengths.
+ (TT_RunIns): Implement display of code position and stack.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make private point numbers work correctly.
+
+ This is completely missing in Apple's documentation: If a `gvar'
+ tuple uses private point numbers (this is, deltas are specified for
+ some points only), the uncovered points must be interpolated for
+ this tuple similar to the IUP bytecode instruction. Examples that
+ need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+ * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+ tt_handle_deltas): New functions.
+ (TT_Vary_Get_Glyph_Deltas): Renamed to...
+ (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+ points and does no longer return an array of deltas.
+ Add tracing information.
+ Call `tt_handle_deltas' to interpolate missing deltas.
+ Also fix a minor memory leak in case of error.
+
+ * src/truetype/ttgxvar.h: Updated.
+
+ * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
+ load_truetype_glyph): Updated.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>

+ [truetype] In GX, make intermediate tuplets work at extrema.

+ * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>

+ [truetype] Add tracing information to GX code.
+
+ * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
+ ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
+ TT_Set_Var_Design, tt_face_vary_cvt): Do it.

+
+ [truetype] Fix commit from 2015-05-22.
+
+ * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
+ with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.

+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix return values of GETINFO bytecode instruction.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
+ `vertical_lcd' and `gray_cleartype'.
+
+ * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
+ Change `symmetrical smoothing' to TRUE, since FreeType produces
+ exactly this.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+ values for symmetrical smoothing, namely 11/18.
+ Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+ (12/19).
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (TT_ExecContext):
+ s/subpixel/subpixel_hinting.
+
+ * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
+
+2015-05-22 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Support selector index 3 of the INSTCTRL instruction.
+
+ This flag activates `native ClearType hinting', disabling backwards
+ compatibility mode as described in Greg Hitchcocks whitepaper. In
+ other words, it enables unrestricted functionality of all TrueType
+ instructions in ClearType.
+
+ * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
+ unconditionally.
+ (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
+ `GS.instruct_control' is active.
+
+ * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
+ (Ins_GETINFO): Updated.
+
+ * docs/CHANGES: Document it.
+
+2015-05-20 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
+ argument.
+
+2015-05-17 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix loading of composite glyphs.
+
+ * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+ ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+ unsigned. I trust `ttx' (which has exactly such code) that it does
+ the right thing here...
+
+ The reason that noone has ever noticed this bug is probably the fact
+ that point-aligned subglyphs are rare, as are subglyphs with a
+ number of points in the range [128;255], which is quite large (or
+ even in the range [32768;65535], which is extremely unlikely).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] Make the `*curveto' operators more tolerant.
+
+ * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
+ `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+ pulling values off the stack until the stack is exhausted.
+ Implicitly the stack must be a multiple (or for subtly different
+ behaviour) a multiple plus a specific number of extra values deep.
+ If that's not the case, enforce it (as the old code did).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] fix incremental interface with new cff code.
+
+ * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
+ interface to retrieve glyph data for a SEAC, it be left to the
+ incremental interface callback to apply the encoding to raw
+ character index (as it was in the previous code).

+
+ [raster] Fix Savannah bug #44022.
+
+ Add fallback for glyphs with degenerate bounding boxes.
+
+ If a glyph has only one very narrow feature, the bbox can end up
+ with either the width or height of the bbox being 0, in which case
+ no raster memory is allocated and no attempt is made to render the
+ glyph. This is less than ideal when the drop-out compensation in
+ the rendering code would actually result in the glyph being
+ rendered.
+
+ This problem can be observed with the `I' glyph (gid 47) in the
+ Autodesk RomanS TrueType font.
+
+ * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
+ dimension is zero to explicitly round up/down (instead of simply
+ round).

+
+ [autofit] Reuse slot glyph loader.
+
+ No need to create a new glyph loader; we can reuse the one from
+ `slot->internal->loader'. It's hard to tell why it was written that
+ way originally, but new code looks sound and correct to me, and
+ avoids lots of allocations.
+
+ * src/autofit/afloader.c (af_loader_init): Change return type to
+ `void'.
+ Don't call `FT_GlyphLoader_New'.
+ (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [autofit] Remove (unused) support for composite glyphs.
+
+ We never have to deal with composite glyphs in the autohinter, as
+ those will be loaded into FORMAT_OUTLINE by the recursed
+ `FT_Load_Glyph' function.
+
+ In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+ FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+ FT_LOAD_NO_HINTING:
+
+ /* resolve load flags dependencies */
+
+ if ( load_flags & FT_LOAD_NO_RECURSE )
+ load_flags |= FT_LOAD_NO_SCALE |
+ FT_LOAD_IGNORE_TRANSFORM;
+
+ if ( load_flags & FT_LOAD_NO_SCALE )
+ {
+ load_flags |= FT_LOAD_NO_HINTING |
+ FT_LOAD_NO_BITMAP;
+
+ load_flags &= ~FT_LOAD_RENDER;
+ }
+
+ and as such the auto-hinter is never called. Thus, the recursion in
+ `af_loader_load_g' never actually happens. So remove the depth
+ counter as well.
+
+ * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+ parameter.
+ <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+ (af_loader_load_glyph): Updated.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Fix uninitialized memory access.
+
+ Apparently `ras.cProfile' might be uninitialized. This will be the
+ case if `ras.top == ras.cProfile->offset', as can be seen in
+ `End_Profile'. The overshoot code introduced in a change `Fix B/W
+ rasterization of subglyphs with different drop-out modes.' (from
+ 2009-06-18) violated this, accessing `ras.cProfile->flags'
+ unconditionally just before calling `End_Profile' (which then
+ detected that `cProfile' is uninitialized and didn't touch it).
+
+ This was harmless, and was not detected by valgrind before because
+ the objects were allocated on the `raster_pool', which was always
+ initialized. With recent change to allocate raster buffers on the
+ stack, valgrind now reported this invalid access.
+
+ * src/raster/ftraster.c (Convert_Glyph): Don't access an
+ uninitialized `cProfile'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [smooth] Fix uninitialized memory access.
+
+ Looks like `ras.span_y' could always be used without initialization.
+ This was never detected by valgrind before because the library-wide
+ `raster_pool' was used for the worker object and `raster_pool' was
+ originally zero'ed. But subsequent reuses of it were using `span_y'
+ uninitialized. With the recent change to not use `render_pool' and
+ allocate worker and buffer on the stack, valgrind now detects this
+ uninitialized access.
+
+ * src/smooth/ftgrays.c (gray_raster_render): Initialize
+ `ras.span_y'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Don't initialize unused `driver->glyph_loader'.

+
+ [base] Don't allocate `library->raster_pool' anymore.
+
+ It's unused after the following commits:
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+ serve, which is, to adjust the pool size. But the pool is now
+ allocated on the stack on demand.
+
+ * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Do not reorder library->renderers upon use.
+
+ Instead of keeping `library->renderers' in a MRU order, just leave
+ it as-is. The MRU machinery wasn't thread-safe.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't fail choosing rasterizer
+ (FT_Err_Cannot_Render_Glyph).
+
+ Easiest to see that crash was to add a `printf' (or otherwise let
+ thread yield in FT_Throw with debugging enabled).
+
+ * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+ (FT_Outline_Render): Don't call `FT_Set_Renderer'.

+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is
+ provided down to the rasterizer, completely ignore that and allocate

+
+ With this patch, rasterizing glyphs from different faces from

+
+ [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+ Previously the code had stipulation for using a per-TT_Size exec
+ context if `size->debug' was true. But there was no way that

+ using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
+ This was, clearly, not threadsafe.
