PIL-resize, aspect ratio

[Kevin Cazabon]

Unfortunately, the only way to "automatically" keep the aspect ratio is to
use the im.thumbnail(maxX, maxY) feature.  However, this uses NEAREST
resizing only.

Otherwise, you have to figure it out yourself, unfortunately.

However, I've asked Fred to add a "im.fit" method to PIL that I wrote a
while back that lets you resize, crop, etc. all at once.  He did at one
point say he was going to roll it into 1.1, however it would seem that it's
not in yet.

I've posted a zip of that stand-alone function, along with a separate module
that lets you rotate images an arbitrary amount, automatically adjusting the
canvas size to fit the entire rotated image (instead of cropping the output
to the input canvas size).

Fred:  any plans to incorporate these still?
