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);
}

Simply use the same number of fragments for each ring, and use
half the number of fragments to determine the number of rings
This results in a sphere that has the same projection when
viewed from above or from the front.

When the sides are vertical we can use 4 sided polygons instead of
triangles to define the sides, this reduces the facet count for the
sides of the cylinder by half.

You might want to apply this patch so that the output of
echo($pi) is not truncated.
