[Image-SIG] Aspect ratio in PIL

[Markus Meyer]

There are two ways to achieve this:

1. Calculate the aspect ratio yourself, then resize the picture 
accordingly, e.g. (not tested)

aspect_ratio = float(im.height) / im.width
im.resize(target_width, target_width  * aspect_ratio)

2. Use the thumbnail function. It creates an image with the given size, 
while padding the edges to preserve aspect ratio, when needed.
