Back to object management!
	Today's goal:  Have Game Objects

Active Learning:
	Add more objects (specifics TBD)

We put together a "better demo" a while back
	Let's finish it, but start from our cross-platform framework

A note on cross-platform:
	I *think* I can keep Source.cpp compatible with Windows
	Just replace it and the old project should work
	I'll test this

Alright, let's get started!
	Basic object definition from before:  Paste in

A question:  How thoroughly should we be integrated with OpenGL?
	If we have lots of time:  Not very
		What if we want to switch to Vulkan or DirectX or Metal?
		What if we want to convert to ray tracing?
	What we'll actually do:  Thoroughly woven together
		Sorry, but our engine will be a lot simpler this way
		I do have aspirations for an RTX build

Next question:  What's an object?
	A thing in the game (kinda generic)
	A thing that correlates with a drawing operation (very convenient, maybe less correct)
	I think we'll go ahead and pick #2
	As always, high performance and simple are at odds
		Our system will be badly adapted to numerous infrequently-used objects
		We might be able to fix that with a special object type later

Storage:  Again, we'll be simple!
	We'll use STL
	One great thing about STL:  We could change the default allocation scheme later

Object interface:
	Some of these we'll do later
		initialize
		draw
		deallocate
		move?  Or should we just move it?
		physics / cycle (per-timeslice operations)
		collisions
			Should encapsulate bounding-box dimensions
			Should it present a 3D space?  Check a point?
	Thread safety:
		All drawing will happen in one thread
			Just to keep our heads screwed on straight
			It's ok, this thread mostly babysits the GPU
				Anything that requires a long time is strictly banned!
				Banned:  malloc/new, file i/o, linear searches, copying vertex buffers, etc
				Allowed:  OpenGL operations, copying uniforms, etc
		Physics and collisions will be in different threads
			Physics and collisions for an object will be single-threaded
			Physics and collisions for different objects might be in different threads
		
Alright, can we get this working, real simple?
	At first:  init and draw
	Never mind delete - it can just crash on close
		Later...

Last thing:  Test it on Windows
	We'll start active learning, but I'll go test it on a Windows machine
