it to work.
See changes in testdata/scad/convex_hull.scad The square(2) was never
rendered it was just there because the hull is calculated when it
itterates onto the second child. I also removed the unneeded parameter.

The code was provided to me by Len Trigg via email.

When the 2d minkowski was enabled the nef2p2 was bailing out too early.
I added a simple p2nef2 based on what projection.cc was doing, and
applied it to the outer_boundary of the polygon_with_holes_2. It now
seems to work for simple scad code such as:
minkowski() {
translate([25,0,0]) square(20);
circle(r=3);
}
