AccessibilityNodeInfo bounds inconsistent with compatibility mode.

1. In compatibility mode a window wide scaling is applied to stretch
   the content. However, AccessibilityNodeInfos retrieved from that
   window contain bounds in application's view of the world and need
   to be scaled to properly relect what a sighted user sees.
