stats.lua: only reprint stats on video-reconfig when toggled

[guidocella]

Make this behave like the comment says it should, because currently when you show oneshot stats and change file, stats are printed again and hide --osd-playing-msg. This happens even if you hide the stats by show-texting something else and change file before the timer expires.

Isn't it more desirable that the stats do update when the file changes here?

[guidocella]

They do update when toggled. stats never update automatically in oneshot mode otherwise and they disappear too quickly to read the new file's info anyway, it just annoyingly overwrites --osd-playing-msg with no way to bring it back.

[Dudemanguy]

The oneshot mode just says it's a fixed duration in the manual.

they disappear too quickly to read the new file's info anyway

I don't agree. With just some leisurely keyboard presses (i, >), much of the updated stats I can easily read before it disappears.

I mean redraw_delay does not apply in oneshot mode, stats are calculated once and are not supposed to refresh. Redrawing on video-reconfig even makes them redraw if they've already been hidden by a different OSD message.
