[In testing, I was able to reproduce Federico's results for most, but
not all, of the test images. There might be some additional
platform-specific discrepancies that need ironed out, but this is a
solid step forward in any case.
Results for a quick run against just the image backend on my system:

The goal is to preserve the precision in the gradients of the edges and
only apply the projection into the final cell location. We also include
the half-subrow offset as spotted by Massimo.

If the join indicates the pair of edges are parallel, we may be
considering the final segment of the spline with a different tangent
vector than the slope of the final edge and so lead to false dropping of
an edge. This has the effect that the line segments between 'arc arc arc
arc' (a rounded rectangle) are no longer horizontal or vertical. As path
construction tries to eliminate joins between colinear segments, this
optimisation should not be required anyway.

With over two thousand references images now, it is starting to make the
test directory look cluttered!
