OpenGL versioning:
	2.0 was the paradigm shift
	3.0 deprecated a lot of stuff left over from 1.x
	We've been avoiding deprecated 1.x stuff anyway, no big deal
	
Changes to update to OpenGL 4.5:
	I decided to change the version number for our wind example

Qualifier changes (sorry):
	in/out instead of varying and attribute
	It's clearer anyway, just forget the others

Other notes:
	gl_FragColor is deprecated in favor of insanity
	Bitwise operators were added!

The generation, actually working now
	My mistake had nothing to do with C or nested functions or C++ or glm
	Tour of the code, in detail
	Works ok...

So, what if we want two of them without adding a second one to GPU memory?
	Main point here:  We're not going to use up extra GPU memory with a second copy
		We're also not going to send it over the PCI express bus again
		So we'll just draw it in a different spot!

Ok, so now that we can do that:
	A:  Let's make a forest
	B:  Let's add some controls so we can walk around
