* 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 TEST (128x128, blend file preview, optional)
* - write FileGlobal (some global vars)
* - write SDNA
* - write USER if filename is ~/X.XX/config/startup.blend
