The test cases considered so far: 314 (new test suite): 1. Check that compression mode isn't compatible with "-f raw" (raw format doesn't support compression). 2. Check that rebasing an image onto no backing file preserves the data and writes the copied clusters actually compressed. 3. Same as 2, but with a raw backing file (i.e. the clusters copied from the backing are originally uncompressed -- we check they end up compressed after being merged). 4. Remove a single delta from a backing chain, perform the same checks as in 2. 5. Check that even when backing and overlay are initially uncompressed, copied clusters end up compressed when rebase with compression is performed. 271: 1. Check that when target image has subclusters, rebase with compression will make an entire cluster containing the written subcluster compressed.
