#1101: Negative buffer does not return empty geometry

Comment (by mdavis):
To refine that idea a bit, for a given area A the shape with the largest
distance to the boundary is a circle. So the radius of the circle of area
A is a lower bound on the negative buffer distance which will cause a
shape to be eroded completely. This is a good optimization to add to the
buffer code, and it might prevent this sort of issue, in large part.
