Patch by Thatcher Ulrich <tulrich@google.com>.

Implement "iframe shim" behavior for windowed plugins.

In FF and IE on windows, iframes are implemented as native HWNDs.  
This has the side effect that iframes display on top of windowed 
plugins. This side effect has long been known as a workaround for
allowing HTML elements to appear above plugin content.
