We need a good way to see absolute frame duration in Frame mode's overview, which is in conflict with auto-scaling of bar height. Suggested fix is: - adjust scale to 30fps == full height by default; - provide a fall-back auto-scale mode when median frame is longer than 1/30s; - add horizontal lines for 30 and 60fps;

Created attachment 146582 [details] screenshot, #333 lines on front, 18fps Here's one with dark lines (a bit too contrast to my taste) No dashes so far, as it turns out WebKit's canvas only supports that via image-based patterns.
