Bug 1230047 (part 2) - Make several PaintWindow() functions use LayoutDevice coordinates. r=kats. Specifically, the PaintWindow() functions in the following classes: - nsIWidgetListener, and its subclasses nsView and nsWebBrowser; - nsChildView; - nsWindow (the one in widget/uikit/); - nsViewManager.
