/// \brief The brush primitive.
///
/// A collection of planes that define a convex polyhedron.
/// The Boundary-Representation of this primitive is a manifold polygonal mesh.
/// Each face polygon is represented by a list of vertices in a \c Winding.
/// Each vertex is associated with another face that is adjacent to the edge
/// formed by itself and the next vertex in the winding. This information can
/// be used to find edge-pairs and vertex-rings.
