We have a view subclass contained in an NSScrollView. After certain operations (such as changing the view scale) we need to change the scroll position, which we do via scrollPoint:, which in turn calls display on the view instead of setNeedsDisplay:YES (which makes sense for simply scroll events which might scroll some pixels and redraw others). We need other things to happen after we set the scroll position, and those things require a redraw as well. Having it draw twice is certainly not optimal. Is there any way to set the scroll position and NOT have it draw immediately?
