>I have a mighty need for something that can quickly render frames of arbitrary pixels. Ideally a line at a time for smoothness. Dependent on the complexity of your application and how comfortable you are working in C++, you could give CImg [1] a go. I've used it for a handful of projects with a similar requirement. It can be lightning quick, but a pain to get started with. [1] https://www.cimg.eu/ https://www.cimg.eu/
