dotCooCoo 138d9499a7 Shape Builder: a line's loose end past a crossing no longer runs out and back in most cases

Since #1035 moved linesweeper to 0.5, the sweep can cut the paths
through one crossing at points more than its tolerance (eps) apart.
The planar map merged a point only into a vertex within eps of it, so
the two passes of an open path could end on two different vertices,
and it kept them as two edges with different ends. Past the crossing,
shape_builder then returned a line's loose end as one piece that runs
out to the line's end and back, and an extra piece of the line it
crosses, about 1.4e-6 long. In live_paint, the face around the loose
end ran out along it and back, and FaceMerger::merge of the faces
returned a second subpath along it. pieces_cut_out_of_their_inputs
fails on main for such an input.

The map now joins the ends of pieces whose middles and ends lie within
16 eps of each other. The two passes then share their ends and become
one edge. The new test is the failing input proptest saved for the
property. Lines that slope close to -1/32 in the document are nearly
level in the sweep's frame, and the change does not cover all of them.
