This test program allocates an array of 16 * 7 uint32_ts and spawns 16 threads that each use 7 of the allocated uint32_ts as a destination image for a large number of composite operations. Each thread then computes and returns a checksum for the image. Finally, the main thread computes a checksum of the checksums and verifies that it matches expectations. The purpose of this test is catch errors where memory outside images is read and then written back. Such out-of-bounds accesses are broken when multiple threads are involved, because the threads will race to read and write the shared memory. V2: - Incorporate fixes from Siarhei for endianness and undefined behavior regarding argument evaluation - Make the images 7 pixels wide since the bug only happens when the composite width is greater than 4. - Compute a checksum of the checksums so that you don't have to update 16 values if something changes. V3: Remove stray dollar sign
