*
* FILE FORMAT
* ===========
*
* 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).
*
* 4 chars
* int, len data after BHead
* void, old pointer
* int
* int, in case of array: number 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 #TEST (#RenderInfo struct. 128x128 blend file preview is optional).
* - write #GLOB (#FileGlobal struct) (some global vars).
* - write #DNA1 (#SDNA struct)
* - write #USER (#UserDef struct) if filename is ``~/.config/blender/X.XX/config/startup.blend``.
