[geos-devel] Modify a linestring or prevent coordinatesequence ownership transfer

Dear GEOS developers,
I would like to know if there is a way, within the GEOS library, to
either 1) modify an existing LineString without copying the existing
points inside or 2) create a LineString from a CoordinateSequence
without having to clone the latter and without it being destroyed with
the LineString (i.e. how to not transfer ownership).
From a quick look at the code, this does not seem possible, but I would
like to make sure it is indeed the case.
Basically I would like to store "growing lines" and check for
intersections between these lines and having to clone
CoordinateSequences every time makes things way too slow...
