[6.1] shipping_api_ups: Shipping label returned is improperly sized/formatted

[Brett Lehrer]

When processing the shipping label, a few things go wrong. First, the requested label dimensions sent (hardcoded) in the XML confirm request are ignored because it's also requesting a GIF. Second, the GIF returned is always 800x1400 pixels, even though the label only takes up 800x1200 pixels. A single line of code after "new_im = new_im.rotate(270)" in shipping_api_ups/stock.py fixes that:

new_im = new_im.crop((0,0,800,1200))

Not cropping out that unused space results in the PDF label's aspect ratio being distorted, which may make the MaxiCode more difficult to read from a UPS scanner (and cost you money and/or your production API key).
