22 * A OSphereLens is a special nonlinear lens that doesn't correspond to any
23 * real physical lenses. It's primarily useful for generating 360-degree
24 * wraparound images while avoiding the distortion associated with fisheye
25 * images.
26 *
27 * A OSphereLens is similar to a Cylindrical lens and PSphereLens, except that
28 * it is orthographic in the vertical direction.
