PES CSewSeg section - frno7/libpes GitHub Wiki
The first CSewSeg segment block's header is the data of the CEmbOne block. If the PES header declares the number of csewseg_segment_block to be 1, then this block contains only the csewseg_segment_block. If zero then this block would be omitted. But, if greater than one, then additional headers and csewseg_segment_blocks are appended within this block.

CSewSeg stitch list subsection
The CSewSeg stitch list subsection is divided into stitch blocks. The last block does not end with the continuation code 0x8003 and so is 2 bytes shorter than the others. Some files seem to limit the number of stitches to a maximum of 1000 per block, is this required?

Header
The header for the first block is contained within the CEmbOne section. However, if the PES Header specified that there would be more than one CSewSeg object these headers will be appended along with additional stitchgroups.
