{- The '_rmPolys' lists which polygons should be cut out to form the indestructible walls of the room.
Link pairs contain a position and rotation to attach to another room;
0 is for links going to another room to the north, pi/2 for links going to a room to the west, etc.
TODO : Explain path, does it need both directions?
Placement spots allow things to be put in the room during level generation.
Room bounds between a new room and previously placed rooms are checked during level generation,
assigning no bounds will allow rooms to overlap.  -}
