auto-sync: draw on idle to avoid flicker/tearing st could easily tear/flicker with animation or other unattended output. This commit eliminates most of the tear/flicker. Before this commit, the display timing had two "modes": - Interactively, st was waiting fixed `1000/xfps` ms after forwarding the kb/mouse event to the application and before drawing. - Unattended, and specifically with animations, the draw frequency was throttled to `actionfps`. Animation at a higher rate would throttle and likely tear, and at lower rates it was tearing big frames (specifically, when one `read` didn't get a full "frame"). The interactive behavior was decent, but it was impossible to get good unattended-draw behavior even with carefully chosen configuration. This commit changes the behavior such that it draws on idle instead of using fixed latency/frequency. This means that it tries to draw only when it's very likely that the application has completed its output (or after some duration without idle), so it mostly succeeds to avoid tear, flicker, and partial drawing. The config values minlatency/maxlatency replace xfps/actionfps and define the range which the algorithm is allowed to wait from the initial draw-trigger until the actual draw. The range enables the flexibility to choose when to draw - when least likely to flicker. It also unifies the interactive and unattended behavior and config values, which makes the code simpler as well - without sacrificing latency during interactive use, because typically interactively idle arrives very quickly, so the wait is typically minlatency. While it only slighly improves interactive behavior, for animations and other unattended-drawing it improves greatly, as it effectively adapts to any [animation] output rate without tearing, throttling, redundant drawing, or unnecessary delays (sounds impossible, but it works).
