	Now, outside of sprites, every pixel on the screen is draw at most once. Hoorah. Unfortunately things still seem to be a little slow, perhaps its the z_buffer access or the fact that vertical floor slice drawing is bad?

2021-09-04	Working on floor casting, but it's not quite right	tslil clingman
	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.
