	The way floors are currently rendered the textures will always appear ``under'' the walls. This is not intended for shorter walls, the floor should be atop them. I might be able to fix this by switching to vertical scan-line rendering of floors -- although i understand that that is less efficient -- and doing this at the same time as wall rendering.
