The reason for that is because of what a square image does when it's mapped to a spherical surface. A good analogy is maps of the globe. Watch Greenland explode in size when it's tranfered from the sphere to a flat map. That's why maps are also displayed in the orange-peel-like format (e.g., \/\/\/). If you want to map a square surface to a sphere, you'll have to generate the image to accomodate how the image is going to get squashed at the poles.
