------------------------+--------------------------
 It seems that if a PreparedPoint is build from a MultiPoint, intersects()
 will return false for any point, for two independent reasons.

 a) PreparedPoint::intersects short-circuits to an equality test.  It looks
 like this was introduced at r4081 / r4132.

 b) the isAnyTargetComponentInTest method does its work using a
 PointLocator, which seems to have no implementation for a Point.
