010 passed on one valid body alone: it now checks the tier-05 part less
the M16 groove (stopped w above the boss's shoulder, run out at its free
top) and the bbox. Two new cases with closed forms: 018, an M10 cut both
hands, whose crossing grooves leave the material fraction squared
(2 pi L int r m^2 dr, exact for L a whole number of pitches); 019, a
two-start Tr40x14(P7), six pitches of the Tr40x7 section. All hold on
SMLib (worst 2e-6 relative).
