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. This is being back-ported to the 1.4.x branch primarily to verify that there are no lingering issues in the existing SIMD extensions.

uses are suitable for testing only. Proper conversion between CMYK and RGB

[2] 'make test' now performs additional bitwise regression tests using tjbench,
mainly for the purpose of testing compression from/decompression to a subregion
of a larger image buffer.
