cd61720845 Merge Pillow changes with Philippe Lagadec’s OleFileIO_PL fork 
Conflicts:
	PIL/OleFileIO.py

I kept Philippe’s version of Unicode decoding that uses UTF-16LE. Pillow
started using Python’s “utf_16” codec in the meantime, but I understand it
uses native byte ordering by default.

7989378bfd Added a way to specify the render size for EPS files. 
There is now a scale parameter that you can pass in to the EpsImageFile.load() function. This parameter is used to specify at what scale Ghostscript renders the EPS internally. Scale needs to be an integer, and all of the internal structures (image size and bounding box) are scaled based on that parameter.

92507e5d0a Fix issue #382: TypeError with TransposedFont's getsize() 
When getting the size of text with a TransposedFont it was failing:

  File "/usr/local/lib/python2.7/site-packages/PIL/ImageDraw.py", line 281, in textsize
    return font.getsize(text)
  File "/usr/local/lib/python2.7/site-packages/PIL/ImageFont.py", line 189, in getsize
    w, h = self.font.getsize(text)[0]
TypeError: 'int' object is not iterable

This is because self.font.getsize(text) returns a (w, h) tuple. To fix, remove the [0].

Test cases have been created in test_imagefont.py: 
test_rotated_transposed_font()
test_unrotated_transposed_font()

Both fail before the fix, both pass with the fix. Furthermore, the code I'm using this from ( https://github.com/mattdeboard/word_cloud ) now works as expected and creates a word cloud similar to the ones that PIL created.

c68044bf7f Fix IOError when saving progressive JPEGs. 
when the jpeg encoder sees the flags optimize or progressive (or progression)
it will write the full image in one shot.

The bufsize needs to be big enough to hold the entire image. The current heuristic
is that the entire compressed image will fit in width * height bytes, but this
heuristic is only applied to save operations with the flag "optimize" and not to
save operations with the flag "progressive".

This patch fixes this oversight.

(Btw, it will probably be a good idea to have a loop that retries with a bigger
bufsize in case this guess is not big enough.)

b4735f7829 Adding support for metadata in webp images. 
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.

Matt Davis
1082173030 Fix Image.fromarray with NumPy arrays 
Image.fromarray attempts to call a method called `tobytes()` on the passed in object, but NumPy arrays don't have a `tobytes()` method, they have a `tostring()` method. (See http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.tostring.html).

I think this was changed accidentally in a Python 3 compatibility update in which this call was confused with the `tobytes` and `frombytes` methods of Image objects.
