38         BLENDER_V100    12 bytes  (versie 1.00)
39                                         V = big endian, v = little endian
40                                         _ = 4 byte pointer, - = 8 byte pointer

42 datablocks:             also see struct BHead

44         <bh.len>                        int,  len data after BHead

50         ...

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

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