Linedef type 8	Special Sector Properties	Floor height	Height of camera's "floor" collision plane (If the frontside sector has Intangible to the Camera applied)
		Ceiling height	Height of camera's "ceiling" collision plane (If the frontside sector has Intangible to the Camera applied)

		Front texture Y offset	Turning speed (in degrees/tic)
Linedef type 16	Minecart Parameters	Front texture X offset	Order of the current Axis/Axis Transfer Line in the track
		Tag 0 makes this affect the front sector, otherwise it will affect all tagged sectors. See also: Minecart tutorial
