      Description

      There is a simple way of improving the performance of drawString by replacing

      string.writePDF( buffer );
      appendRawCommands( new String( buffer.toByteArray(), "ISO-8859-1"));
      appendRawCommands( SPACE );

      with

      string.writePDF( buffer );
      appendRawCommands( buffer.toByteArray() );
      appendRawCommands( SPACE );

      as the appendRawCommands(String) simple does a appendRawCommands(str.getBytes( "ISO-8859-1" ));
      Therefore this optimization should spare the String creation as well as the conversion back to a byte array.
