+   *
+   * @note:
+   *   The values returned are not pointers into the internal structures of

+   *   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

+   *   be retrieved.  So, for example, PostScript procedures such as NP, ND,
+   *   and RD are not available.  Arbitrary keys are, obviously, not be
