title: PIL zoom into image at a particular point
body: <p>I'm creating some images with python imaging library (PIL). Now, like we zoom into a map at a particular location, I want to similarly zoom into my image at a specified point. Note that this is different from resizing the image. I want the size to remain the same. I couldn't find any inbuilt method in the documentation that does this. Is anyone aware of a method that might achieve this. I'd ideally like to do this without other dependencies like openCV.</p>
