> 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.
