We use a cast to indicate that we intentionally ignore a function's
return value. However, this doesn't apply to API functions where
errors can only happen for trivially invalid input.

(t42_parse_encoding): Do it.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

Make `strike_index' FT_ULong and always defined.
Use `load_strike_metrics' provided by SFNT interface.
pfr_face_done, pfr_face_get_kerning, pfr_slot_init, pfr_slot_done,
pfr_slot_load): Don't use PFR_XXX but FT_XXX arguments which are
typecast to the proper PFR_XXX types within the function.
Update code accordingly.
* src/pfr/pfrdrivr.c (pfr_get_kerning, pfr_get_advance,

metrics->x_scale and metrics->y_scale.

Direct_Move_Y but without touching.

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.

computing `available_sizes->width' but make it always equal to

as enumeration.
* src/pcf/pcfdrivr.c (pcf_driver_class), src/winfonts/winfnt.c

the FT_MODULE_DRIVER_NO_OUTLINES flag.
* 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/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:
added PFR-specific public API. Fixed the kerning retrievel routine
(it returned invalid values when the outline and metrics resolution
differ)
* src/base/ftsynth.c: fixed the synthetic emboldener. at last.
* src/base/ftobjs.c: small internal fix to better support
bitmap-based font formats
parameter sign-ness in callback function
* include/freetype/config/ftmodule.h,
include/freetype/internal/fttrace.h,
src/Jamfile, src/pfr/*:
adding a PFR font driver to the FreeType sources. Not that it
doesn't support embedded bitmaps or kerning tables for now..
* include/freetype/internal/ftmemory.h: adding the FT_MEM_ZERO
and FT_ZERO macros
* include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3,
FT_NEXT_UOFF3, FT_NEXT_OFF3_LE and FT_NEXT_UOFF3_LE to parse
in-memory 24-bit integers.
