The bug last time in the roof thing:
	x and y were mixed up
	I fixed that, plus added texture coordinates and a roof texture

Midterm review guide

Can we dress up our maze algorithm as a building generator?
	It'll need a roof of some sort
	A floor probably shouldn't be bigger than the floor below it
		Usually, but not always true of buildings
	Might be good if it had a pitched roof
		Maybe later
	Windows:
		Easy answer:  Exterior might have a window
		Could model this as a hole
			We could say it's a ruin...
		Could also have a window in the texture
		Partial transparency is possible too
			We haven't really done that yet
	Added bonus:  The interior will be explorable

Pitched Roofs:
	rise and run
		How many inches up per foot?
		12/12 is a 45 degree angle
		You can't describe a wall this way
	Implication for texture:  It'll affect our coordinates
		We can calculate how easy enough
	rise and run refer to the sides of the triangle
		Not the hypothenuse
	A minor problem:  Scaling with multiple pitches
		Not really a problem if all roofs are pitched the same
		Could account for it by adjusting texture coordinates

Variables in creating a segment for our building:
	Slope direction (or is it in the center?)
	Eves?  If it's on the end or edge

To avoid scaling problems:  A separate eve function
	It'll have to have 4 directions possible
	
Materials and product photos:
	A lot of the time, they're actually pretty good textures
	Usually copyrighted though

Lab on this:
	Make a function that generates a building, given a width, height, and location
		A building can have either a rectangular or a round footprint
		It doesn't need to be crazy complicated or anything
			Just look like some kind of building
		You don't need to use the maze generator for the building
	Place 10 buildings of different sizes on some kind of ground, to make a village

Should there be a lab on mazes?
	Probably
	It can run the week of the test
