I knew geometry.intersects()... I have to find an efficient way to use
it. I'll give a try using it inside the AddPoint function within
OpenLayers.Handler.Point, starting withh the Path Handler for
simplicity.
I think I will do the following:
1. Extract tha last segment from the Line Geometry collection.
2 . Create a clone of the Line and remove the last component from it.
3. Verify the Geometry.intersects() between the two.
This should avoi the use of a loop...
