py3k: Import Christoph Gohlke's test suite 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. 2012-10-16 00:26:38 +04:00			`from tester import *`

backport PIL's PNG/Zip improvements - add new FASTOCTREE quantizer with alpha support - make ZIP compress level and type configurable - support reading/writing PNGs with paletted alpha source https://bitbucket.org/effbot/pil-2009-raclette/commits/3637439d51693c92028a7c4cfa75f5db583de357 2013-03-11 23:33:04 +04:00			`def test_octree_quantize():`
