That would mean that the "Offset Table" has neither any offsets in it 
nor any information relating to offsets...

Commontype does something very similar, but with "table directory" 
instead of "font directory" (because that top level structure is a 
directory... of tables...). So it calls the whole thing from byte 0 of a 
non-collection file to byte 12+numTables*20 the "table directory", which 
contains a number of "table directory entries". No "offset table" or 
"font directory".
