-/* Bitstream description

- * The picture is divided into blocks that are zlib-compressed.

- *

- * The decoder is fed complete frames, the frameheader contains:

- *  4 bits of block width

- * 12 bits of frame width

- *  4 bits of block height

- * 12 bits of frame height

- *

- * Directly after the header are the compressed blocks. The blocks

- * have their compressed size represented with 16 bits in the beginning.

- * If the size = 0 then the block is unchanged from the previous frame.

- * All blocks are decompressed until the buffer is consumed.

  * Encoding ideas: A basic encoder would just use a fixed block size.

  * Block sizes can be multiples of 16, from 16 to 256. The blocks don't

  * have to be quadratic. A brute force search with a set of different
