WebEdit: So, I've worked this out a bit, and would appreciate if somebody could verify that this would be the proper way to triple buffer my lights SSBO. Assume we split it into three buffers: A, B, and C. Display A, while drawing into B. In my case, I guess "drawing" would actually mean writing my updated light positions into the buffer.
