GetFurnitureMarkerID
Though equivalent conditions may or may not be valid, this console command is a no-op.
Before it was removed from the game, it returned 0 for invalid, 1 - 10 for beds, and 11 - 20 for chairs. These are the FurnitureMarker nodes built into furniture objects. This function is used in the idle manager to pick an animation to get into and out of furniture.
