This is from http://scary.beasts.org/security/CESA-2004-001.txt. This was missing from Gohlke's tests. With this file, I see 79 tests and no failures on my setup from 2.6/2.7.
This is Christoph Gohlke's test suite from his personal PIL package found at http://www.lfd.uci.edu/~gohlke/pythonlibs/. This is just to bring it in as a separate commit. Future commits will align it with Pillow.
