src/truetype/ttobjs.c, src/cff/cffobjs.c, src/sfnt/sfobjs.c: implementing new
heap-optimized embedded bitmap loader. This one also fixes bug #12107
* src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without
a 'kern' table.
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 had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
TT_NAME_ID_PREFERRED_FAMILY and TT_NAME_ID_PREFERRED_SUBFAMILY.
* src/cff/cffload.c (cff_font_load): Always create inverse mapping.
Even if the charstring count id different from the CID count, it is
still possible that the font uses a different CID -> GID mapping.
src/autofit/afloader.c, src/autohint/ahhint.c:
moved the definition of 'lsb_delta' and 'rsb_delta' from FT_GlyphMetrics
to FT_GlyphSlotRec. The old location did BREAK BINARY COMPATIBILITY
of the library !!
* src/sfnt/sfobjs.c: removing compiler warning

Use FT_LOCAL.

handles the retrieval of Postscript font name for a given face.

FT_MEM_MOVE.
* include/freetype/freetype.h (FT_ENCODING_SJIS, FT_ENCODING_GB2312,
FT_ENCODING_BIG5, FT_ENCODING_WANSUNG, FT_ENCODING_JOHAB): New
enumerations of FT_Encoding. The FT_ENCODING_MS_* variants except
FT_ENCODING_MS_SYMBOL are now deprecated.
Updated all users.
* docs/CHANGES: Document it.
include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
defined to return the baseline-to-baseline distance. This was
already the value returned by the BDF and PCF drivers.
The `width' field now gives the average width. I wasn't able to
find something better. It should be taken as informative only.
New fields `size', `x_ppem', and `y_ppem'.
* src/pcf/pcfread.c (pcf_load_font): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.

FT_Bitmap_Size.
Redesigning the FNT driver to return multiple faces, not multiple
strikes. At least one font (app850.fon from WinME) contains
different FNT charmaps for its subfonts. Consequently, the previous
design of having multiple bitmap strikes in a single font face fails
since we have only one charmap per face.
* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.
(FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with
`font'.
* src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated.

bitmap width is now ignored.
(FNT_Load_Glyph): Updated.
Fix glyph index computation.
(winfnt_driver_class): Updated.
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.

want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
fixing the SFNT name table loader to support various buggy fonts.
it now ignores empty name entries, entries with invalid pointer
offsets and certain fonts containing tables with broken "storageOffset"
fields.
name strings are now loaded on demand, which reduces the memory
requirements for a given FT_Face tremendously (for example, the
name table of Arial.ttf is about 10Kb and contains 70 names !!)
finally, this is a _quick_ fix. The whole name table loader and
interface will be rewritten in a much more cleanly way shortly,
once CSEH have been introduced in the sources.

src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h:
updated the SFNT charmap support to use FT_CMaps
changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer..
note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the
code more generic and less error-prone..
src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
that it accepts broken fonts like "foxjump.ttf", which made FreeType
crash when trying to load them.
Also improved the name table parser to be able to load
Windows-encoded entries before Macintosh or Unicode ones, since it
seems some fonts don't have reliable values here anyway.
* include/freetype/internal/tttypes.h (TT_CMap0, TT_CMap2, TT_CMap4,
TT_CMap6): Adding field `language'.
(TT_CMapTable): Removing field `language'.
Type of `length' field changed to FT_ULong.
Adding fields for cmaps format 8, 10, and 12.
(TT_CMapGroup): New auxiliary structure.
(TT_CMap8_12, TT_CMap10): New structures.
* include/freetype/tttables.h (TT_HoriHeader, TT_VertHeader):
Removed last element of `Reserved' array.
* include/freetype/ttnameid.h (TT_PLATFORM_CUSTOM, TT_MS_ID_UCS_4,
TT_NAME_ID_CID_FINDFONT_NAME): New macros.
* src/sfnt/ttcmap.c (TT_CharMap_Load): Updated loading of `language'
field to the new structures.
Fixed freeing of arrays in case of unsuccessful loads.
Added support for loading format 8, 10, and 12 cmaps.
(TT_CharMap_Free): Added support for freeing format 8, 10, and 12
cmaps.
(code_to_index4): Small improvement.
(code_to_index6): Ditto.
(code_to_index8_12, code_to_index10): New functions.
* src/sfnt/ttload.c (TT_Load_Metrics_Header): Updated to new
structure.
(TT_Load_CMap): Ditto.
* src/sfnt/sfobjs.c (tt_encodings): Add MS UCS4 table (before MS
Unicode).
* src/type1/t1driver.c (t1_get_name_index): Fix compiler warning.
