/*
FILEFORMAT: IFF-style structure  (but not IFF compatible!)

start file:
	BLENDER_V100	12 bytes  (versie 1.00)
					V = big endian, v = little endian
					_ = 4 byte pointer, - = 8 byte pointer

datablocks:		also see struct BHead
	<bh.code>			4 chars
	<bh.len>			int,  len data after BHead
	<bh.old>			void,  old pointer
	<bh.SDNAnr>			int
	<bh.nr>				int, in case of array: amount of structs
	data
	...
	...

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

WRITE

Preferred writing order: (not really a must, but why would you do it random?)
Any case: direct data is ALWAYS after the lib block

(Local file data)
- for each LibBlock
	- write LibBlock
	- write associated direct data
(External file data)
- per library
	- write library block
	- per LibBlock
		- write the ID of LibBlock
- write FileGlobal (some global vars)
- write SDNA
- write USER if filename is ~/.B.blend
*/

Important to know is that 'streaming' has been added to files, for Blender Publisher
