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