After some time the data were recorded without compression. I decide to make "QEMU-IMG convert" for that image to reduce its size. I want a new option, which selects between the two algorithms overdriven = images: 1. extract all / compress again when converting images (in the current im= plementation) 2. compress only uncompressed blocks and just copy the compressed blocks = without re-compression. This option is only needed when converting compressed image to compressed and the compression algorithm is the same.
