*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.
