-
--	when a node child is a solid leaf the node child number is zero
--	two adjacent areas (sharing a plane at opposite sides) share a face
-	this face is a portal between the areas
--	when an area uses a face from the faceindex with a positive index
-	then the face plane normal points into the area
--	the face edges are stored counter clockwise using the edgeindex
--	two adjacent convex areas (sharing a face) only share One face
-	this is a simple result of the areas being convex
--	the convex areas can't have a mixture of ground and gap faces
-	other mixtures of faces in one area are allowed
--	areas with the AREACONTENTS_CLUSTERPORTAL in the settings have
-	cluster number zero
--	edge zero is a dummy
--	face zero is a dummy
--	area zero is a dummy
--	node zero is a dummy
