37                                         V = big endian, v = little endian
38                                         _ = 4 byte pointer, - = 8 byte pointer

50 Almost all data in Blender are structures. Each struct saved
51 gets a BHead header.  With BHead the struct can be linked again
52 and compared with StructDNA .

56 Preferred writing order: (not really a must, but why would you do it random?)
57 Any case: direct data is ALWAYS after the lib block
58
59 (Local file data)
60 - for each LibBlock
61         - write LibBlock
62         - write associated direct data
63 (External file data)
64 - per library
65         - write library block
66         - per LibBlock
67                 - write the ID of LibBlock
68 - write TEST (128x128, blend file preview, optional)
69 - write FileGlobal (some global vars)
70 - write SDNA
71 - write USER if filename is ~/X.XX/config/startup.blend
