Reverted revision 670341 and replaced it with a different solution as discussed:

addCharacters() is now deprecated and called by the new characters() method which uses start/length instead of start/end.
Fixed bugs in the AFP and PS extensions (ArrayIndexOutOfBoundsExceptions). They were not properly changed when the interface changed.
