Bug 1054326: Initial attempt to submit Imagecompare test framework and test cases int...

...o the main branch
I just remembered why i was doing this way:  it is nearly impossible for me to install PIL on mac!  Well, it installs, but when you try to import it, I get following error:
>> from PIL import Image
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/mozilla/.virtualenvs/2.2/lib/python2.7/site-packages/PIL/Image.py", line 62, in <module>
    from PIL import _imaging as core
ImportError: dlopen(/Users/mozilla/.virtualenvs/2.2/lib/python2.7/site-packages/PIL/_imaging.so, 2): Symbol not found: _TIFFClientOpen

  Expected in: flat namespace

I think it's something to do with having 32bit libraries were 64 bit ones are required, but if you have a workaround could you help me out?  Thanks!
