The current Fps manager will sometime skip the intended delay and start the next frame immediately, I'm not 100% sure why it happens, but I rewrote most of it to stay consistent and improved the overall precision by compensating for OS wake delay after sleep and finishing with a busy wait I also changed the behavior of mlx_set_fps_goal to allow zero/negative values and treat them as uncapped (like most graphics libraries)
