A change in convention:  At least use namespace std and glm

First thing:  It's a little hard to tell where we are!
	Making a bunch of our objects, in different colors or something
	Instanced rendering and the vertex shader, what we pass to the fragment shader
	We'll probably want different shaders for the floor
	Try to keep glDraw calls minimal, and do a lot with each call
		But if you want to change shader programs, you have to make another call

How about some kind of floor?
	We can use tiles
	Could also just do one big one
	
Now that there's a floor, let's jump!
	Usually that's the spacebar
	But it's an instant thing, not a hold!
	Double-jumping?  We'll leave it for now
		For development, it often helps to have a fly mode of some sort

Framerate:  We're artificially limiting it
	First:  Let's figure out what the framerate actually is
	What happens now if we take out the limiter?
	glfwGetTime to control rotation rather than count
	Is vsync on?  How does it work in glfw anyway?

The movement really should be separate
	Movement shouldn't slow down if framerate does
	A new std::thread
	Rate limiting:  Can set usleep based on glut, or set a timer

A raised place in the floor:
	It just changes the floor level in a certain area

UI note:  
	It's normally rendered
	You can render without having applied an MVP
	glRaster and glutBitmapCharacter, probably similar with glfw
	That's how it worked last time, but we'll use Dear ImGui this semester
		Dear ImGui is better
