37//! A simple closed curve in Euclidean plane divides the
38//! plane in to two disjoint, open connected components; one
39//! bounded, one unbounded. The bounded one is called the
40//! interior region to the curve. Unbounded component is called
41//! exterior region to the curve. The domain of the trimmed
42//! surface is defined as the interior of the outer boundaries
43//! and exterior of the inner boundaries and includes the
44//! boundary curves.
