Loading an obj file!

Obj files:
	First:  Let's make one with Blender
		Blender is a large and complicated program
		I've used it for a few things, but not recently
			I'm kind of a klutz with the UI
		Export a trivial obj file anyway
	Note:  Normals
		For lighting, might or might not be in our obj file
	We could parse this file
	
tinyobjloader:
	tinyobj imports a namespace
	Documentation:  read the code
	Unique vertices, and tinyobjloader
		We'll use elements, like usual
	A decision:  We'll lift some code from hello_triangle_gui

An object that loads a model from a file:
	init routine:  The stuff we just did plus:
		Load the vertices into memory
		Load texture coordinates?  Need that or color
			A hack:  Color by texture coordinates
			We'll fix it later
		Load elements into memory
	We don't actually need the file in memory once it's on the GPU
		If we had multiple levels or areas, we might want to keep it
	List of instances of our object

Draw:
	Pretty much like our other objects

Alright, the textures:
	stbi_image, and loading it into memory
	Again, we can steal from hello_triangle_gui
	The fragment shader will have to load from a texture
		We can grab the Vulkan one and adapt it
	The vertex shader will have to pass the texture coordinates through
		Just like it did with color
	If we're using textures, we don't need "regular" colors
		Might as well save the memory and time

Did any of this work?
	I'm hoping this can be the active learning:
		Save some other obj from Blender and load it in the game
		Faster:  I could give you an obj to start with
