Hi Barand,

Please add to the todo list an algorithm checking if geometries
intersects but not taking boundries into account (intersects() &&
!touches()). It would be used e.g. in rtree traversing in tests for
nodes'/boxes containing geometries which may be within some area. Still
there is no need to hurry since there is no big difference between this
and plain intersects() which is used now.
