+   *       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.
