/*

|
|
- 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 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
|
|
the cluster number set to the negative portal number
|
|
- edge zero is a dummy
|
|
- face zero is a dummy
|
|
- area zero is a dummy
|
|
- node zero is a dummy
