2004-02-10  Werner Lemberg  <[e-mail]>

	Make the PS parser more tolerant w.r.t. non-standard font data.  In
	general, an error is only reported in case of a syntax error; a
	wrong type is now simply ignored (if possible).  To be independent
	of the order of various MM-specific keywords, the parse_shared_dict
	routine has been removed -- the PS parser is now capable to skip
	this data.  It no longer fails on parsing e.g.

	  dup /WeightVector exch def

	Since the token following /WeightVector isn't `[' (starting an
	array) it is simply ignored.

	* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a
	new internal error value.

	* src/type1/t1load.c (parse_blend_axis_types,
	parse_blend_design_positions, parse_blend_design_map): Return
	T1_Err_Ignore if no proper array is following the keyword.
	(parse_weight_vector): Use T1_ToTokenArray, initializing `blend'
	structure, if necessary.
	Return T1_Err_Ignore if no proper array is following the keyword.
	(parse_shared_dict): Removed.
	(parse_encoding): Set parser->root.error to return T1_Err_Ignore
	if no result can be obtained.
	Check for errors before accessing `elements' array.
	(t1_keywords): Remove /shareddict.
	(parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.
	Set keyword_flag only in case of success.
	Check error code if skipping an unrecognized token.
	(T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend
	if blend commands haven't set up a proper MM font.

	* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special
	code for synthetic fonts.
	Return PSaux_Err_Ignore if no proper value has been found.
