++ \brief Defines a box collision shape.
++
++ This type defines a box collision shape. The origin is at the center of the box.
++
++ \note A non-uniform scaling transformation will scale the x, y and z directions individually.
++ However, combining non-uniform scale and rotation may lead to shearing, which will not be applied
++ to the BoxShape: it will always be a rectilinear box.
