You misunderstand : the bar widget (both parts, loop ruler and bar buttons) 
has the length of the window it's in, no more, no less. It's not really 
scrolling, it's being repainted differently.

Because it was late and I couldn't figure out out to get it working according 
to the way the widget was painted. I did actually started to use it, but it 
wouldn't work, and going the plain dumb obvious way seemed to work, so...
