I decided I really ought to show you what OpenCL is like
	It's put together pretty well
	I keep talking about it, and this won't take all that long

opencl demo with image filters, flashlights, etc
	It still worked on nimrod
	Build with -lOpenCL

Can we do that with a compute shader?
	Sure
	We can borrow the line to load the image
	Have to put the image in a buffer
		Could use a texture, I suppose
	Remember SOIL_save_image
	If we just do a green filter or something, we can modify it in-place
	Or we could make two buffers, or whatever
