- Freetype Update to 2.1.10. Reduces memory usage, increases speed and
fixes drawing bugs.
- Enable Bytecode. Weird_W's fonts finally look humanly readable.
Thanks to Waxdragon for testing.

LATEST CHANGES BETWEEN 2.1.10 and 2.1.9
I. IMPORTANT BUG FIXES
- The size comparison for BDF and PCF files could fail sometimes.
- Some CFF files were still not loaded correctly. Patch from
Derek Noonburg.
- The stroker still had some serious bugs.
- Boris Letocha fixed a bug in the TrueType interpreter: The
NPUSHW instruction wasn't skipped correctly in IF clauses. Some
fonts like `Helvetica 75 Bold' failed.
- Another serious bug in handling TrueType hints caused many
distortions. It has been introduced in version 2.1.8, and it is
highly recommended to upgrade.
- FreeType didn't properly parse empty Type 1 glyphs.
- An unbound dynamic buffer growth was fixed in the PFR loader.
- Several bugs have been fixed in the cache sub-system.
- FreeType behaved incorrectly when resizing two distinct but very
close character pixel sizes through `FT_Set_Char_Size' (Savannah
bug #12263).
- The auto-hinter didn't work properly for fonts without a Unicode
charmap -- it even refused to load the glyphs.
II. IMPORTANT CHANGES
- Many fixes have been applied to drastically reduce the amount of
heap memory used by FreeType, especially when using
memory-mapped font files (which is the default on Unix systems
which support them).
- The auto-hinter has been replaced with a new module, called the
`auto-fitter'. It consumes less memory than its predecessor,
and it is prepared to support non-latin scripts better in next
releases.
- George Williams contributed code to read kerning data from PFM
files.
- FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and
TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for
setting family and style in SFNT fonts (patch from Kornfeld
Eliyahu Peter).
- A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has
been added to retrieve name and size information of SFNT tables.
- A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has
been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB,
JSTF). After validation it is no longer necessary to check
for errors in those tables while accessing them.
Note that this module might be moved to another library in the
future to avoid a tight dependency between FreeType and the
OpenType specification.
- A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert',
`FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has
been added. Its use is to convert an FT_Bitmap structure in
1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap,
probably using a different pitch, and to further manipulate it.
- A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer
control how outlines are embolded.
- `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps
also (code contributed by Chia I Wu). Note that this function
is still experimental and may be replaced with a better API.
- The method how BDF and PCF bitmap fonts are accessed has been
refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size
were synonyms in FreeType's BDF and PCF interface. This has
changed now. FT_Set_Pixel_Sizes should be used to select the
actual font dimensions (the `strike', which is the sum of the
`FONT_ASCENT' and `FONT_DESCENT' properties), while
FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE'
property). In both functions, the width parameter is ignored.
III. MISCELLANEOUS
- The BDF driver no longer converts all returned bitmaps with a
depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has
not mentioned this explicitly, but implementors might have
relied on this after looking into the source files.
- A new option `--ftversion' has been added to freetype-config to
return the FreeType version.
- The memory debugger has been updated to dump allocation
statistics on all allocation sources in the library. This is
useful to spot greedy allocations when loading and processing
fonts.
- We removed a huge array of constant pointers to constant strings
in the `psnames' module. The problem was that compilations in
PIC mode (i.e., when generating a Unix shared object/dll) put
the array into the non-shared writable section of the library
since absolute pointers are not relocatable by nature.
This reduces the memory consumption by approximately 16KByte per
process linked to FreeType. We now also store the array in a
compressed form (as a trie) which saves about 20KByte of code as
well.
- Kirill Smelkov provided patches to make src/raster/ftraster.c
compile stand-alone again.

+
+ Say you have `(Foo*)x' and want to assign, pass, or return it as
+ `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C
compiler
+ would warn you that type casting incompatible pointer types
breaks
+ strict-aliasing. The solution is to cast to `(void*)' instead
which
+ is the generic pointer type, so the compiler knows that it
should
+ make no strict-aliasing assumption on `x'. But the problem with
+ `(void*)x' is that seems like in C++, unlike C, `void*' is not a
+ generic pointer type and assigning `void*' to `Bar*' without a
cast
+ causes an error. The solution is to cast to `Bar*' too, with
+ `(Bar*)(void*)x' as the result -- this is what the patch does.

+
+ Implement several memory optimizations to drastically reduce the
+ heap usage of FreeType, especially in the case of memory-mapped
+ files. The idea is to avoid loading and decoding tables in the
+ heap, and instead access the raw data whenever possible (i.e.,
when
+ it doesn't compromise performance).
+
+ This has several benefits: For example, opening vera.ttf now
uses
+ just a small amount of memory (even when the FT_Library
footprint is
+ accounted for), until you start loading glyphs. Even then, you
save
+ at least 20KB compared to the non-optimized case. Performance
of
+ various operations, including open and close, has also been
+ dramatically improved.
+
+ More optimizations to come, especially for the auto-hinter.
+
+ * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New
+ function type.
+ (SFNT_Interface): Add it.
+
+ * include/freetype/internal/tttypes.h (TT_HdmxEntryRec,
TT_HdmxRec,
+ TT_Kern0_PairRec): Don't define if FT_OPTIMIZE_MEMORY is set.
+ (TT_FaceRec): Define `horz_metrics', `horz_metrics_size',
+ `vert_metrics', `vert_metrics_size', `hdmx_table',
+ `hdmx_table_size', `hdmx_record_count', `hdmx_record_size',
+ `hdmx_record_sizes', `kern_table', `kern_table_size,
+ `num_kern_tables', `kern_avail_bits', `kern_order_bits' if
+ FT_OPTIMIZE_MEMORY is set.
+ Don't define `hdmx', `num_kern_pairs', `kern_table_index',

+ (sfnt_done_face): Call `tt_face_done_kern'.
+ Handle horizontal metrics for FT_OPTIMIZE_MEMORY.
+
+ * src/sfnt/ttkern.c, src/sfnt/ttkern.h: New files. Code has
been
+ taken from `ttload.c' and `ttload.h'.
+ Provide special versions of `tt_face_load_kern',
+ `tt_face_get_kerning', and `tt_face_done_kern' for
+ FT_OPTIMIZE_MEMORY.
+
+ * src/sfnt/ttload.c (tt_face_load_metrics, tt_face_load_hdmx,
+ tt_face_free_hdmx): Provide version for FT_OPTIMIZE_MEMORY.

+2005-02-22 David Turner <david at freetype.org>
+
+ * src/base/ftdbgmem.c: Partly rewritten. Added the ability to
list
+ all allocation sites in the memory debugger. Also a new
function
+ FT_DumpMemory() was added. It is only available in builds with
+ FT_DEBUG_MEMORY defined, and you must declare it in your own
code to
+ use it, i.e., with something like:
+
+ extern void FT_DumpMemory( FT_Memory );
+
+ ...
+
+ FT_DumpMemory( memory );
+
+ * include/freetype/config/ftoption.h
+ (TT_CONFIG_OPTION_BYTECODE_INTERPRETER): Comment out definition
--
+ again.
+ (FT_OPTIMIZE_MEMORY): New configuration macro to control various
+ optimizations for reducing the heap footprint of memory-mapped
+ TrueType files.
+
+ * include/freetype/internal/ftmemory.h (FT_ARRAY_ZERO): New
+ convenience macro.
+
+ * include/freetype/internal/tttypes.h (TT_FaceRec)
+ [FT_OPTIMIZE_MEMORY]: Use optimized types for `num_locations'
and
+ `glyph_locations'.
+
+ * src/truetype/ttgload.c (load_truetype_glyph): Call
+ `tt_face_get_location'.
+
+ * src/truetype/ttobjs.c (tt_face_init)
+ [FT_CONFIG_OPTION_INCREMENTAL]: Improve error handling.
+ (tt_face_done): Call `tt_face_done_loca'.
+
+ * src/truetype/ttpload.c (tt_face_get_location,
tt_face_done_loca):
+ New functions. If FT_OPTIMIZE_MEMORY is set, the locations
table is
+ read directly from memory-mapped streams, instead of being
decoded
+ into the heap.
+ (tt_face_load_loca) [FT_OPTIMIZE_MEMORY]: New implementation.
+ (tt_face_load_cvt, tt_face_load_fpgm): Only load table if the
+ bytecode interpreter is compiled in.
+
+ * src/truetype/ttpload.h: Updated.
+
+ * src/autohint/ahglyph.c (ah_outline_load): Improve allocation
