Make reference valid HTML 4.01 transitional. * src/tools/docmaker/tohtml.py (html_header_1): Add doctype and charset. (html_header_2): Fix style elements and add some more. Fix syntax. (block_header, block_footer, description_header, description_footer, marker_header, marker_footer, source_header, source_footer, chapter_header, chapter_footer): Don't use <center>...</center> but `align=center' table attribute. Use double quotes around table widths given in percent. (keyword_prefix, keyword_suffix): Don't change font colour directly but use a new <span> class. (section_synopsis_header, section_synopsis_footer): Don't change colour. (print_html_field): <tr> gets the `valign' attribute, not <table>. (print_html_field_list): Ditto. (index_exit): Don't use <center>...</center> but `align=center' table attribute. (toc_exit, section_enter): Ditto. (block_enter): Use <h4><a>, not <a><h4>. This change reimplements fix from 2003-05-30 without breaking binary compatibility. * include/freetype/t1tables.h (PS_FontInfoRec): `italic_angle', `is_fixed_pitch', `underline_position', `underline_thickness' are reverted to be normal values. * include/freetype/internal/psaux.h (T1_FieldType): Remove `T1_FIELD_TYPE_BOOL_P', `T1_FIELD_TYPE_INTEGER_P', `T1_FIELD_TYPE_FIXED_P', `T1_FIELD_TYPE_FIXED_1000_P'. (T1_FIELD_TYPE_BOOL_P, T1_FIELD_NUM_P, T1_FIELD_FIXED_P, T1_FIELD_FIXED_1000_P): Removed. (T1_FIELD_TYPE_BOOL): Renamed to... (T1_FIELD_BOOL): New macro. Updated all callers. * src/type42/t42parse.c: `italic_angle', `is_fixed_pitch', `underline_position', `underline_thickness', `paint_type', `stroke_width' are reverted to be normal values. (T42_KEYWORD_COUNT): New macro. (t42_parse_dict): New array `keyword_flags' to mark that a value has already been assigned to a dictionary entry. * src/type42/t42objs.c (T42_Face_Init, T42_Face_Done): Updated. * src/cid/cidtoken.h: `italic_angle', `is_fixed_pitch', `underline_position', `underline_thickness' are reverted to be normal values. * src/cid/cidobjs.c (cid_face_done, cid_face_init): Updated. * src/psaux/psobjs.c (ps_parser_load_field): Updated. * src/type1/t1tokens.h: `italic_angle', `is_fixed_pitch', `underline_position', `underline_thickness', `paint_type', `stroke_width' are reverted to be normal values. * src/type1/t1objs.c (T1_Face_Done, T1_Face_Init): Updated. * src/type1/t1load.c (T1_FIELD_COUNT): New macro. (parse_dict): Add parameter for keyword flags. Record only first instance of a field. (T1_Open_Face): New array `keyword_flags'.

*
* @function:
* FT_Get_PS_Font_Value
*
* @description:
* Retrieve the value for the supplied key from a PostScript font.
*
* @input:
* face ::
* PostScript face handle.
*
* key ::
* An enumeration value representing the dictionary key to retrieve.
*
* idx ::
* For array values, this specifies the index to be returned.
*
* value ::
* A pointer to memory into which to write the value.
*
* valen_len ::
* The size, in bytes, of the memory supplied for the value.
*
* @output:
* value ::
* The value matching the above key, if it exists.
*
* @return:
* The amount of memory (in bytes) required to hold the requested
* value (if it exists, -1 otherwise).
*
* @note:
* The values returned are not pointers into the internal structures of
* the face, but are `fresh' copies, so that the memory containing them
* belongs to the calling application. This also enforces the
* `read-only' nature of these values, i.e., this function cannot be
* used to manipulate the face.
*
* `value' is a void pointer because the values returned can be of
* various types.
*
* If either `value' is NULL or `value_len' is too small, just the
* required memory size for the requested entry is returned.
*
* The `idx' parameter is used, not only to retrieve elements of, for
* example, the FontMatrix or FontBBox, but also to retrieve name keys
* from the CharStrings dictionary, and the charstrings themselves. It
* is ignored for atomic values.
*
* PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
* get the value as in the font stream, you need to divide by
* 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
*
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can
* be retrieved. So, for example, PostScript procedures such as NP,
* ND, and RD are not available. Arbitrary keys are, obviously, not be
* available either.
*
* If the font's format is not PostScript-based, this function returns
* the `FT_Err_Invalid_Argument' error code.
