clipPolyfaceUnderOverConvexPolyfaceIntoBuilders MethodStatic

• Split facets of mesh "A" into parts that are
  • under mesh "B"
  • over mesh "B"
• both meshes are represented by visitors rather than the meshes themselves
  • If the data in-hand is a mesh, call with mesh.createVisitor
• The respective clip parts are fed to caller-supplied builders.
  • Caller may set either or both builders to toggle facet order (e.g. toggle the lower facets to make them "point down" in cut-fill application)
  • This step is commonly one-half of "cut fill".
    • A "cut fill" wrapper will call this twice with the visitor and builder roles reversed.
• Both polyfaces are assumed convex with CCW orientation viewed from above.
