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

  53 Preferred writing order: (not really a must, but why would you do it random?)
  54 Any case: direct data is ALWAYS after the lib block
  55
  56 (Local file data)
  57 - for each LibBlock
  58         - write LibBlock
  59         - write associated direct data
  60 (External file data)
  61 - per library
  62         - write library block
  63         - per LibBlock
  64                 - write the ID of LibBlock
  65 - write FileGlobal (some global vars)
  66 - write SDNA
  67 - write USER if filename is ~/.B.blend
