David Turner 6f8c622996 * src/autofit/aftypes.h, src/autofit/afhints.h,
src/autofit/afmodule.c: adding support for disabling
        horizontal and vertical hinting for the purpose of debugging
        the auto-fitter

David Turner f3050059dd * src/sfnt/sfobjs.c (tt_face_get_name): support some function
which report their English names through an Apple Roman
        (platform,encoding) pair, with language_id != English

        if the font uses another name entry with language_id == English,
        it will be selected correctly though.

        * src/truetype/ttobjs.c: add unpatent-hinting selection for
        "mingli.ttf"

Werner Lemberg 36d2eab054 * src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
values which have the upper two bytes set to 0xFF instead of 0xFF
(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
`HAN NOM B.ttf').

* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.

Fix miscellaneous compiler warnings.

	* freetype2/include/freetype/internal/ftobjs.h: close
	comment with `*/' to avoid `/* in comment' compiler warning.

	* freetype2/src/base/ftdbgmem.c (ft_mem_table_get_source): Turn
	cast `(FT_UInt32)(void*)' into `(FT_UInt32)(FT_PtrDist)(void*)'
	since on 64-bit platforms void* is larger than FT_UInt32.

	* freetype2/src/base/ftobjs.c (t_validator_error): cast
	away volatileness of argument to ft_longjmp. Spotted by
	Werner `Putzfrau' Lemberg.

	* freetype2/src/bdf/bdflib.c (bdf_load_font): initialize
	local variable `lineno'.

	* freetype2/src/gxvalid/gxvmod.c (classic_kern_validate):
	mark local variable `error' volatile.

Fix for previous commit, which caused many compiler warnings/errors
	about addresses of volatile objects passed as function arguments
	as non-volatile pointers.

	FT_Validator typedef a pointer to a volatile object.

	* freetype2/src/gxvalid/gxvmod.c (gxv_load_table): Make function
	argument `table' a pointer to a volatile object.

	* freetype2/src/otvalid/otvmod.c (otv_load_table): Make function

Werner Lemberg e9a746674a Fix handling of self-delimiting tokens. 2006-06-26 17:37:44 +00:00
Werner Lemberg c011f4cba1 The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'.  This makes the parser more robust as it

(skip_literal_string): Add FT_Error as return value.
Handle escapes better.

Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.
