/**
* This singleton manages multiple instances of rwt.widgets.base.Iframe.
*
* The problem: When dragging over an iframe then all mouse events will be
* passed to the document of the iframe, not the main document.
*
* The solution: In order to be able to track mouse events over iframes, this
* manager will block all iframes during a drag with a glasspane.
