Reshape the sack so it stops being an amphora

Browse source 
The profile put its widest point a quarter of the way up and narrowed from
there all the way to the neck, which is the silhouette of a vase. A filled
sack does close to the opposite: it SPREADS where it meets the ground,
because the grain settles and cloth has no stiffness of its own, then runs
nearly parallel up most of its height, and gathers in sharply only where
the cord is tied. Almost the entire difference between the two shapes
lives in the bottom level and in where the taper starts.

With the body right, the collar was what still read as a vessel: it opened
out to 0.46 of the radius over a fifth of the sack's height, which is the
mouth of a bottle. Above the tie there should be a hand's width of gathered
cloth and no flare to speak of.

27 models, 18481 triangles, all checks pass, 0 floating cases.

// where the cord is tied. Nearly the whole difference between the two
// shapes is in the bottom level and in where the taper begins.
