Up until now, the SimpleBlock was treated specially: It basically had its own EBML category and it was also included in the BlockGroup EBML syntax (although a SimpleBlock must not exist in a BlockGroup according to the Matroska specifications). The latter fact also meant that a MatroskaBlock's buffer was always unreferenced twice. This has been changed: The type of a SimpleBlock is now an EBML_BIN. The only way in which SimpleBlocks are still different is that they share their associated structure with another unit (namely BlockGroup). This is also used to unref the block: It is always unreferenced via the BlockGroup syntax.
