Giving it a cursory glance, I think it's mostly current. Is there
something specific that isn't working for you?

Hello,

it feels like the code was refractored (changed?) and those
instructions never updated?

But my experience is that if you need to push the data to the CPU,
that pretty much overwhelms the advantages you get by rendering on the
GPU.
And OpenGL only supports simple primitives -- so it's substantially
more a pain to do something as sole as render a filled polygon, let
alone a spline.
And yes, back In the day, it was faster to render on the video card,
but CPUs have gotten a lot faster, and memory busses not so much.
But whatever, I think we all agree that pushing the transformations to
the GPU is the big win.
