       tag_index is larger or equal to the number of entries in the  tag  list  0xFFFFFFFF  (=(uint32_t(-1))  is
       returned.

       The  known  tags  to  libtiff are define as 'named' tags and a lot of them as custom tags. The custom tag
       definitions are handled in an internal custom tag list. This list can also  be  extended  by  adding  tag
       definitions to that list, so that libtiff is aware of those tags.  See DefiningApplicationTags
