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.
