Bug 1370757 - Don't expand the dirty rect for Mac native widget drawing. r=mattwoodrow Extending it didn't play well with invalidation; widgets would only be able to draw outside if the invalidated region of the current paint was larger than the widget's declared paint rect but not if the widget was the only thing that got invalidated. Any legitimate widget overflow should instead be handled by GetWidgetOverflow. The DrawCellWithSnapping overflow is considered to stay within the focus ring's bounds. I fuzzed two reftests which have extremely slight variance when -moz-appearance is combined with box-shadow. I don't really understand this failure but I don't think it's worth looking into either.
