This method is very similar to crop. It extracts the rectangle
specified by its arguments from the image and returns it as a new
image. However, excerpt does not respect the virtual page offset and
does not update the page offset and is more efficient than cropping.
It is the caller's responsibility to ensure that the rectangle lies
entirely within the original image.
