We now have a test harness for EPS files. Two variants were created one for the default scale=1 and one where scale=2. These two tests are run against two different EPS files, one with zero for the start of the bounding box and one where this is not the case. PNG test renders are used to make sure the output match what we expect. Lastly the sample EPS files were generated using the included create_eps.gnuplot file and the gnuplot program on a Mac.
Pillow now uses the webpmux library to envelop the webp images in RIFF. This allows for easy support of exif and icc_profile metadata.
Also included tests that verify compatibility with jpeg for exif and icc_profile metadata.
If the user does not have webp with webpmux enabled, pillow will fall back to the previous approach, meaning no exif or icc_profile metadata will be read or written to.
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.
