PG
is embedded and adjExternal
is an adjecenty entry in PG
.PG | is the planarized representation for which a layout shall be computed. PG may be modified during the call. |
adjExternal | is an adjaceny entry in PG that shall be on the external face of the drawing. |

m_cOverhang * m_separation is the minimum distance between the glue point of an edge and a corner of the vertex boundary.
