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.

David Turner 6aa260ce61 support for "automatic unpatented hinting" added
we still need to determine the list of "trick" CJK fonts
that are going to toggle the bytecode interpreter instead
of the auto-hinter

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


	* freetype2/include/freetype/internal/ftvalid.h: Make
	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
	argument `table' a pointer to a volatile object.

T1_FIELD_XXX. (parse_dict): Ignore keywords that occur in the wrong
dictionary (e.g., in Private instead of FontDict).

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.

(skip_procedure): New function.
(ps_parser_skip_PS_token): Handle procedures.
Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.

* src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
Add commented-out code for synthetic fonts.

          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%.
