Add a test and a GM for the factory, and a PNG file for it to decode. The PNG file is copyright-free, obtained from http://openclipart.org/detail/29213/paper-plane-by-ddoo In cmykjpeg, do not attempt to decode in the constructor, since it currently crashes on Mac (if you provide the correct resource path). Even when we fix this crash there is no need to do it in the constructor, since we create all of the gms in order to get their names (to determine whether to run them).
