src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
`Ascender', and `Descender' from an AFM.
* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.
* include/freetype/freetype.h (FT_FaceRec): Mention that fields may be
changed after file attachment.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed
later !!

FT_Request_Metrics): New base functions to set the font metrics. They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.
* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL. That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching. This was what we did and it
does cause some problems without rounding.
* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.
s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected. This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.

* src/psaux/psconv.c, src/psaux/psconv.h: New files to provide
conversion functions (e.g, PS real number => FT_Fixed) for the
PS_Parser and AFM_Parser. Some of the functions are taken, with some
modifications, from the psobjs.c
* src/psaux/psobjs.c: Use functions from psconv.c.
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c:: Add
`AFM_Parser' to the `psaux' service.

vertical metrics.

The fake metrics is monotone.
* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
formattings in vertical metrics faking. There are still rooms for
improvements (and so do the CFF module).
(PCF_Glyph_Load), src/winfonts/winfnt.c (FNT_Load_Glyph): Don't set
the linear advance fields as they are only for the outline glyphs.

The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
change need be made to the code.

decide whether to use the auto-hinter according to documentation.
There should to be no real difference.
Some checks (e.g., is text height positve?) after the glyph is loaded.

Be careful that scales won't be negative.

src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:
Added support for an embedded 'BDF ' table within SFNT-based
bitmap font files. This is used to store atoms & properties from
the original BDF fonts that were used to generate the font file.
the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
and is used to implement FT_Get_BDF_Property for these font files.
At the moment, this is still experimental, the BDF table format isn't
cast into stone yet.

- adding generation of exported symbols list to the build system, including the Unix one !!
sorry Werner, I have no time to document this in ChangeLog at the moment
font to have no `head' table if tables `SING' and `META' are
present; this is to support `SING Glyphlet'.
`SING Glyphlet' is an extension to OpenType developed by Adobe
primarily to facilitate adding supplemental glyphs to an OpenType
font (with emphasis on, but not necessariy limited to, gaiji to a
CJK font). A SING Glyphlet Font is an OpenType font that contains
the outline(s), either in a `glyf' or `CFF' table, for a glyph;
`cmap', `BASE', and `GSUB' tables are present with the same format
and functionaliy as a regular OpenType font; there are no `name',
`head', `OS/2', and `post' tables; there are two new tables, `SING'
which contains details about the glyphlet, and `META' which contains
metadata.
Further information on the SING Glyphlet format can be found at:
http://www.adobe.com/products/indesign/sing_gaiji.html
* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
macros for the OpenType tables `SING' and `META'. These two tables
are used in SING Glyphlet Format fonts.
a preliminary section with some explanations about user allocation.
* src/tools/docmaker/tohtml.py (HtmlFormatter.section_enter):
Don't abort if there are no data types, functions, etc., in a
section.
Print synopsis only if we have a data type, function, etc.
* docs/INSTALL.ANY, docs/INSTALL, docs/INSTALL.UNX, docs/CUSTOMIZE,
docs/INSTALL.GNU, docs/TRUETYPE, docs/DEBUG, docs/UPGRADE.UNX,
docs/VERSION.DLL, docs/formats.txt: Revised, formatted.
