> `lines(t, buffer)` will run into the conversion machine and will just collect the buffer I’m afraid. I will need to double check, but `GLBuffer(Point2f[...])` may get to OpenGL without getting converted

When tracing with NSight, I didn’t see any copies to CPU memory (i.e., no DtoH copies), so I don’t think it converted back.
