\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.
