Thanks to improvements at a low-level that Matthew made, DrRacket's scrolling performance is much improved (specifically when responding to a scroll event, DrRacket now uses a blit copy to avoid a complex redraw for the portion of the screen that's still there after the scroll happens and does the complex redraw only for the new portion of the screen).
