To keep anti-aliasing label computation tractable, vertex labels are initially assigned based solely on boundary edges. This can occasionally cause interior chord edges between boundary vertices to be mislabeled as boundary edges. This CL identifies and subdivides these mislabeled interior edges, inserting a midpoint vertex labeled as interior to break the chord. PiperOrigin-RevId: 977650099
