This tool is used to perform a nonlinear resize (or "warp") of an image. By warping, you can resize an image such that the objects in the center of an image remain clear and undistorted, and distortion occurs near the edges of the image. This tool is useful for situations where you need to convert an image from one aspect ratio to another without cropping. I often use it when creating wallpapers when I have a wallpaper that is not the correct aspect ratio to display on my desktop.
About aspect ratios:
An aspect ratio is the ratio between the width and height of an image. For example, analog TV pictures have an aspect ratio of 4:3 = 1.33:1. Widescreen (HDTV) pictures have an aspect ratio of 16:9 = 1.78:1. If you try to convert an image from one aspect ratio to another, the image will become distorted. For example, converting a analog TV picture to a wide TV picture would amount to the picture being "stretched" horizontally. People in the picture end up looking fat.
However, you can also perform something called a nonlinear resize, or a warp. A nonlinear resize stretches the image more at the edges than at the center. For example, a person standing in the center of a picture may appear normal, whereas a person standing near the edge would become fattened.
