Dear,

Do we agree the only difference between the index::is_overlapping vs.
ggl::overlaps is that ggl considers common edges as NOT overlapping while
spatial_index considers they are?

spatial_index' function is not very efficient, and that is noticeable in a
drawing loop.

Obviously, "else-ing" the X and Y if's would already be a nice optimization
;-)
