Hybrid scanline sync with front edge sync VS back edge sync framerate limiter

Just a small video demonstrating how different framerate limiting modes used in hybrid scanline sync configuration affect tearline stability and simulation-to-render latency. - Front edge sync framerate limiter mode is used in the beginning. Such configuration favors tearline position stability. Expected simulation-to-render latency is close to 1 frame - Back edge sync framerate limiter mode is selected in the end. It drastically reduces simulation-to-render latency at cost of less stable and more jittery tearline position.
