[cctalk] Re: oscilloscopes

I wrote and tuned the code twenty years ago, but haven't looked at whether better results might be possible by wasting the capabilities of current systems (SIMD libaries and/or multiple cores). I felt like I only was able to give a slim impression, and I've also wondered what could be done with 4K HDR displays: making points round(!) and simulating the "bloom" and intensity of repeatedly or highly intensified spots.
