This structure is a place-holder for parameters that may be
introduced in future to control the generation of collision data
when using the functions RpCollisionWorldSectorBuildData,
RpCollisionWorldBuildData or
RpCollisionGeometryBuildData.
Currently, a NULL pointer should be passed to these functions, as
no parameters are defined. If parameters are introduced, a NULL
pointer will indicate that default values should be used.
