 A new image compression algorithm.
 
-In the newest version, the algorithm performs in most cases better then PNG. In fact the only image that get's bigger is img_4. The original img_2.png, for example is 12.8 MB; the compressed binary has only a size of 10.1 MB. However this is only achieved through aggressive settings on Zlib and takes quite some time to calculate.
