Project:  Working out the details
	If you really want to do something, let me know!

Geometry shaders, further examples:
	Since lab actually took a while this time
	Adding branch thickness to the tree
	Adding fruit to the tree
	How about both fruit AND branches with actual thickness?
		It would be good to know how far along we are (junction or fruit)
		An easy way that increases realism anyway:  Terminal branches are short
		Another way:  Fruit is a separate point cloud
	Dropping the fruit:
		We just have to know how far down it ought to be at any given point
	
In some cases, using a geometry shader can be slow
	Don't make a lengthy geometry shader program with few invocations
	Memory and caching:  All primitives have to be cached, then rasterized
		- So, it's not a free pass to make all the geometry you please!

LOD and tesselation:  Probably next time, or in not all that long anyway
	tesselation and later compute shaders took some of the roles intended for geometry shaders

Class topics in the near future:
	tesselation shaders
	feedback
	compute shaders
