In the process of developing the AltiVec extensions, it was discovered that the normal regression tests aren't sufficient to test the behavior of the library with very small image sizes and when compressing from/decompressing to a subregion of a larger image buffer. Thus, an additional regression test was added that takes advantage of the tiled compression/decompression feature in tjbench.
