C++ general note:
	C++ is C with extra features added
		Mostly
	This means C programs are also C++ programs
	Library authors sometimes avoid using C++ features
		That way the library works with either one
	OpenGL, Vulkan, and many others do this
	GLM will be an exception

Displaying with the Video Card, general procedure for OpenGL 4.0+ or Vulkan
	Load whatever you want to display in main memory
		Format should be xyzxyzxyz, or xyzwxyzwxyzw, or something like that
	Move the list of vertices into video memory
	Same thing for colors, if you want those
	rgbargbargba, or rgbrgbrgb, or something like that
	Load a vertex shader
		It's a program that says what to do with the vertices (transformations, etc)
		Can also assign color to a vertex
	Load a fragment shader
		It's a program that figures out what color each fragment should be
		fragment = pixel
		Input will include which vertices were used to determine this fragment
		Can also include a color, determined by what the vertex shader output
	Start the main loop, which will:
		Prepare the transformation matrix or matrices for the next scene, if anything is moving	
		Clear the framebuffer
		Draw a new frame

How would Vulkan be different?
	Nothing in the above is wrong for vulkan
	But each step will require more detail
	OpenGL makes a lot of assumptions about what you want
	They'll be basically correct for what we're doing
	If they weren't, then we'd be in for a hard time of it

Lab 2:  Something with OpenGL
	Depends where we end up after Tuesday

C/C++ note:
	We're *probably* going to hit stuff that wasn't emphasized in CS211
	Stop me when we do
		Sometimes it's easier to learn something when you need it anyway

Simple demo that you can run:
	glad vs. glew
		Both set up OpenGL functions we'll use later
		Both also include the function prototypes for GL functions
	glfw3 handles our windows and OS interaction
		This makes it so Linux and Windows versions are really similar
	Once we reach the main loop:
		glm library uses operator overloading for matrix math


C++ and objects and this:
	Reminder:  An object encapsulates properties and methods
		We can trigger methods by calling them OR using operators
		They can be triggered other ways too (constructor, destructor, etc)
