<div class="markdown level1 summary"><p>This method extracts a marker segment in a tile-part header and stores
it into a byte buffer for the second pass. The marker is first
recognized, then its flag is activated and, finally, its content is
buffered in an element of byte arrays accessible thanks to a hashTable.
If a marker segment is not recognized, it prints a warning and skip it
according to its length.</p>
