Useful when shapes are aligned along the y-axis (e.g. because of a bilateral symmetry) and when one wants to retain just the upper side.

a matrix
of (x; y) coordinates or a Coo object (Out are returned as Opn)
When shapes are "sliced" along the y-axis, it usually results on open curves and thus to huge/artefactual gaps between points neighboring this axis. This is usually solved with coo_slidegap. See examples there.
Also, when apply a coo_left/right/up/down on an Out object, you then obtain an Opn object, which is done automatically.
