* .kra with compressed tiles using deflate and no global compression: 27MB 
saving time 23s
* .kra with compressed tiles using quickz [1] and no global compression: 74MB 
saving time 1.6s
* .kra with compressed tiles using lzo [2] and no global compression: 58MB 
saving time 2.0s
* for referenced, totally uncompressed that file is 177MB and takes around 4s 
to save
