This structure is used to provide an estimate of the position of an end of a
line of separation.

Used in:

PK_ENTITY_range_o_t
PK_ENTITY_range_vector_o_t
PK_GEOM_range_o_t
PK_GEOM_range_vector_many_o_t
PK_GEOM_range_vector_o_t
PK_TOPOL_range_geom_o_t
PK_TOPOL_range_o_t
PK_TOPOL_range_vector_o_t

If the corresponding entity is a curve or an edge, then an estimate of the
curve parameter may be supplied in `parameters[0]'. If the corresponding
entity is a surface or face, then an estimate of the uv surface parameters
may be supplied in `parameters[0]' and `parameters[1]'. If the corresponding
entity is a curve, surface, edge or face then an estimate of the end position
may be provided in 'vector'. 'vector' is expected to be on or close to
the entity.
