smooth scrolling causes tearing #550

I'm using Windows 10 on a 60 hz display. When I enable smooth scrolling I see visual tearing and other glitches. I know this effect from programs that don't respect v-sync. Maybe it's the same issue here? I looked in the source, but couldn't easily figure out how to implement v-sync.

@tfriedel Hi :) Thanks for the report. What version are you using?

From 0.6.8 to the latest, the smooth scrolling behavior is improved. V-sync is not implemented, but the latest may have a small improvement.

@akiyosi I was using the nightly from end of july and also the version I just built from source.

The glitches are more pronounced when using the "scroll wheel" function of my trackball. Then it seems like the text near the top is moving faster than at the bottom. If I scroll just with for example "Page Down", then only the tearing effects are visible.
