/**
*
* FILE FORMAT
* ===========
*
* IFF-style structure (but not IFF compatible!)
*
* Start file:
*
* `BLENDER_V100` `12` bytes (version 1.00 is just an example).
* `V` = big endian, `v` = little endian.
* `_` = 4 byte pointer, `-` = 8 byte pointer.
*
*
* data-blocks: (also see struct #BHead).
*
* `bh.code` `char[4]` see `BLO_blend_defs.h` for a list of known types.
* `bh.len` `int32` length data after #BHead in bytes.
* `bh.old` `void *` old pointer (the address at the time of writing the file).
* `bh.SDNAnr` `int32` struct index of structs stored in #DNA1 data.
* `bh.nr` `int32` 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``.
