Labs are due at the end of the next lab.

Couple things that would make our demo a LOT easier to use:
	A function to make shaders
	A function print shader errors
	glGetShaderInfoLog(GLuint, length_of_the_log, &length_report_for_log, actual_log)
	glGetShaderiv(GLuint, GL_INFO_LOG_LENGTH, &where_the_length_goes)
	We don't have to keep allocating and deallocating memory for this - a general buffer is ok
		Can even be used to store shader code
		Will impose a maximum length!

Note also:  Most of these functions can fail
	They return error codes
	Could be really useful to know!
	scolor library, stop on compile failure

Adding a few more vertices:
	We can make a pyramid!
	
Note about colors:  You can also just generate these
	In the vertex shader, with relation to x, y, and z
	In the fragment shader, based on something from the vertex shader
	This can be useful for debugging!

Depth buffering:
	I'm not sure if I can induce a problem here
	glEnable and GL_DEPTH_TEST
	glClear and GL_DEPTH_BUFFER_BIT
	With GLUT, you had to turn this on for the window
		As far as I can tell, glfw has it on, and you can only set the number of bits
	From looking through here:
		https://www.glfw.org/docs/latest/window_guide.html

Note about lighting:
	We'll do it in the fragment shader, at some point
	Not right away!  Lots of stuff to cover first
	RTX 3090 demos are happening, release this month, expensive
