One may want to build the rtree index on mpts when mpts has more
components than mplg, but then one would have to track the points that
are already known to be in one of mplg's polygons and avoid checking
again (which may fail and cause false alarm) for other polygon components.
Such maintenance brings extra cost and performance test prooves that
it's not desirable.
The containers tried for such maintenance including std::vector<bool>,
std::set<array_index>, mpts[i].set_props().
Also, even if the mplg has only one polygon, i.e. the worst case for
building rtree index on mplg, the performance is still very very close to
the linear search done in multipoint_within_geometry_internal.
So always build index on mplg as below.
