+ Fixed position elements are misplaced when a WK1 view has contentInsets set

+ -and corresponding-
+ <rdar://problem/17682335>
+
+ Reviewed by Tim Horton.
+
+ [NSScrollView documentVisibleRect] includes content that is within the inset-area
+ of a view, but WebCore is interested in the content that is fully visible, so we
+ need to factor the inset sizes out of this rect.
+
+ Implement contract() to avoid the awkwardness of calling expand() with negative
+ values.

+
+ Factor out insets
+ * platform/mac/ScrollViewMac.mm:
