++ \brief Defines a spherical collision shape.
++
++ This type defines a spherical shape. The origin is at the center of the sphere.
++ \note When using a scaling transformation with this shape, the x component will be used to scale the diameter of
++ the sphere. The resulting shape will be perfectly round, even if a non-uniform scaling transformation is used.
