-The Smoke Codec
----------------
-
-This is a very simple compression algorithm I was toying with when doing a
-Java based player. Decoding a JPEG in Java has acceptable speed so this codec
-tries to exploit that feature. The algorithm first compares the last and the 
-new image and finds all 16x16 blocks that have a squared difference bigger than
-a configurable threshold. Then all these blocks are compressed into an NxM JPEG.
-The quality of the JPEG is inversely proportional to the number of blocks, this
-way, the picture quality degrades with heavy motion scenes but the bitrate stays
-more or less constant.
-Decoding decompresses the JPEG and then updates the old picture with the new
-blocks.

-TODO:
-----
-- make format extensible
-- motion vectors
-- do some real bitrate control
