Possibly leave some parts of the resulting image unclaimed by partitions in
the emerging GPT in order to increase he chance to get in GPT the
partition numbers given with option -append_partition.
@*
The ISO 9660 filesystem gets marked by a GPT partition
only if none of the appended partitions has partition number 1,
and if no other command causes a partition inside the emerging ISO 9660
filesystem, and if -partition_offset is 16.
@*
If this option is not given, then gap filling partitions will be inserted
so that no part of the emerging image after block 16 is unclaimed by GPT
partitions. This happens only if partitions get appended and a valid GPT
emerges, e.g. by option -appended_part_as_gpt.
Commands which produce isohybrid-style invalid GPT disable gap filling.
