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.

Adam
