FileSize field of DXContainer header should match DXContainer file size, as far as I understand. On the current mainline, FileSize is 3548, but the actual size of the file produced by this test is 1996 bytes. Therefore I think the FileSize value 3548 was wrong. 1996 + 8 (size of ILDB PartHeader) + 32 (ILDB part content size) + 4 (a new entry for ILDB part in PartOffsets) = 2040.
