Werner Lemberg 0708b23e80 [psaux] Fix some value overflows.
* src/psaux/psconv.c (PS_Conv_ToFixed): Implement it.

Werner Lemberg 292144b44a [psaux] Fix Savannah bug #35657.
If in function `skip_spaces' the routine `skip_comment' comes to the
end of buffer, `cur' is still increased by one, so we need to check
for `p >= limit' and not `p == limit'.

* src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.

* src/*: Do it.

Werner Lemberg 048b756389 * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
integer part is zero.

Werner Lemberg 545c4e566e * src/truetype/ttgload.c (TT_Load_Composite_Glyph)
[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.


Formatting, documentation fixes.

David Turner 281679de85 * include/freetype/internal/tttypes.h, src/autofit/afangles.c,
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
        src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
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 !!

Wu, Chia-I (吳佳一) bcc438b15e * include/freetype/freetype.h (FT_Select_Size): Rename the second
argument from `idx' to `strike_index'.
(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
this enum.

* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
FT_REQUEST_HEIGHT): New macros to get the width and height of a
request, in fractional pixels.

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
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.

* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
(tt_size_request): Set the font metrics.
Call cff_size_select/tt_size_select when some strike is matched.

* src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c,
src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c,
src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
Set the font metrics.
s/index/strike_index/.

* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
files were committed.  Just a catch-up.
(PS_Conv_ToFixed): Remove the `goto'.
(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
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.

Wu, Chia-I (吳佳一) 108fdbbbd3 * src/psaux/afmparse.c, src/psaux/afmparse.h: New files which
implement an AFM parser.  It is used to parse an AFM file.

* 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.

* src/psaux/psaux.c, src/psaux/rules.mk: Include those new files.

* src/tools/test_afm.c: A test program for AFM parser.

* include/freetype/internal/services/svkern.h,
include/freetype/internal/ftserv.h: New service `Kerning'.  It is
currently only used to get the track kerning information.

* src/type1/t1driver.c, src/type1/t1objs.c, src/type1/t1afm.c,
src/type1/t1afm.h: Update to use the AFM parser.
Provide the `Kerning' service.

* include/freetype/freetype.h, src/base/ftobjs.c: New API
`FT_Get_Track_Kerning'.
