+%	Encrypts fromString according to the algorithm for Adobe
+%	  Type 1 fonts, writing the result into toString.
+%	  toString must be at least as long as fromString or a
+%	  rangecheck error occurs.  state is the initial state of
+%	  the encryption algorithm (a 16-bit non-negative
+%	  integer); newState is the new state of the algorithm.
