`is_fixed_pitch', `underline_position', `underline_thickness' are
reverted to be normal values.
* include/freetype/internal/psaux.h (T1_FieldType): Remove
`T1_FIELD_TYPE_BOOL_P', `T1_FIELD_TYPE_INTEGER_P',
`T1_FIELD_TYPE_FIXED_P', `T1_FIELD_TYPE_FIXED_1000_P'.

(T1_FIELD_TYPE_BOOL): Renamed to...
(T1_FIELD_BOOL): New macro. Updated all callers.

`underline_position', `underline_thickness', `paint_type',
`stroke_width' are reverted to be normal values.
(T42_KEYWORD_COUNT): New macro.

`underline_position', `underline_thickness', `paint_type',
`stroke_width' are reverted to be normal values.
* src/type1/t1objs.c (T1_Face_Done, T1_Face_Init): Updated.
* src/type1/t1load.c (T1_FIELD_COUNT): New macro.
(parse_dict): Add parameter for keyword flags.
Record only first instance of a field.
(T1_Open_Face): New array `keyword_flags'.
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.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.

FT_Bitmap_Size.
* src/winfonts/winfnt.c (FNT_Face_Init): Updated to properly fill
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.
* src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal
to pixel_height.

select face index.
Updated to load just one subfont.
(fnt_font_done, FNT_Face_Done): Updated.
(FNT_Face_Init): Handle `face_index'.
Updated.
(FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the
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.
* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

FT_GlyphSlot_Internal object.
ft_glyph_bbox_subpixels, ft_glyph_bbox_gridfit,

FT_GLYPH_BBOX_UNSCALED, FT_GLYPH_BBOX_SUBPIXELS,
FT_GLYPH_BBIX_GRIDFIT, FT_GLYPH_BBOX_TRUNCATE, FT_GLYPH_BBOX_PIXELS.
The lowercase variants are now (deprecated aliases) to the uppercase
versions.
Updated all other files.

as enumeration.
* src/pcf/pcfdrivr.c (pcf_driver_class), src/winfonts/winfnt.c
(winfnt_driver_class), src/bdf/bdfdrivr.c (bdf_driver_class): Add
the FT_MODULE_DRIVER_NO_OUTLINES flag.
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
src/gzip/zutil.h: updates to allow compilation without compiler
warnings with LCC-Win32
* include/freetype/freetype.h, docs/VERSION.DLL,
builds/unix/configure.ac: updates for the upcoming 2.1.4 release
* docs/VERSION.DLL: updating document to better explain the differences between
the three version numbers being used on Unix, as well as provide the AutoConf
fragment provided by Lars Clausen
* src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
prevented bezier arcs with negative vertical coordinates to be rendered
appropriately
2002-11-27 Vincent Caron <v.caron@zerodeux.net>
* builds/unix/unix-def.in, builds/unix/freetype-config.in,
builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
adding support for system zlib installations when available on the
target platform (Unix only)
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour

* src/cff/cffparse.c (cff_parse_real): User cast for assigning
`exp'.
* src/cff/cffload.c (cff_index_get_pointers): Use FT_ULong for
some local variables.
(cff_charset_load, cff_encoding_load): Use casts to FT_UInt for some
switch statements.
(cff_font_load): Use cast in call to CFF_Load_FD_Select.

* src/raster/ftrend1.c (ft_raster1_render): Ditto.
* src/sfnt/sfnt_dir_check: Compare `magic' with unsigned long
constant.
* builds/amiga/include/freetype/config/ftmodule.h: Updated.
include/freetype/ftstroker.h, include/freetype/ftsysio.h,
include/freetype/ftsysmem.h, include/freetype/ttnameid.h:
updating the in-source documentation
* src/tools/docmaker/tohtml.py: updating the HTML formatter in the
DocMaker tool
* src/tools/docmaker.py: removing obsolete file
debug mode of template instantiation
* src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
empty arrays, and this prevented the loading of certain fonts.
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
prevent seg fault when hints are provided in an empty glyph !!
* include/freetype/ftimage.h: removed incorrect "zft_" definitions
and updated constants documentation comments

src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
ft_encoding_symbol to be FT_ENCODING_MS_SYMBOL (instead of
the erroneous FT_ENCODING_SYMBOL)
* builds/unix/unix-def.in: added "datadir" definition
(thanks to Anthony Fok)
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_.
of the "load_flags" parameter of FT_Load_Glyph and FT_Load_Char from
"FT_Int" to "FT_Int32", this in order to support more options.
this should only break binary and/or source compatibility on
16-bit platforms (Atari?)
