title: Programmatically scrolling NSTextView without scrollbar
body: <p>I'm trying to scroll a textview programmatically using the <code>scrollToPoint</code> method. This works fine if the textview has a scrollbar, but if I disable it with <code>setHasVerticalScroller:NO</code>, I get some strange results: if I try to scroll using the two-finger gesture after the programmatic scroll, the textview automatically jumps back to the point that was shown before the programmatic scroll. I already tried redrawing the textview and actualizing it, but nothing worked.</p>
