Ehsan Akhgari 8c296bbcd4 Bug 579517 - Part 1: Automated conversion of NSPR numeric types to stdint types in Gecko; r=bsmedberg

future reference:

/**
* The focus manager deals with all focus related behaviour. Only one element
* in the entire application may have the focus at a time; this element
* receives any keyboard events. While there is only one application-wide
* focused element, each nsIDOMWindow maintains a reference to the element
* that would be focused if the window was active.
*
* If the window's reference is to a frame element (iframe, browser,
* editor), then the child window contains the element that is currently
* focused. If the window's reference is to a root element, then the root is
* focused. If a window's reference is null, then no element is focused, yet
* the window is still focused.
*
* The blur event is fired on an element when it loses the application focus.
* After this blur event, if the focus is moving away from a document, two
* additional blur events are fired on the old document and window containing
* the focus respectively.
*
* When a new document is focused, two focus events are fired on the new
* document and window respectively. Then the focus event is fired on an
* element when it gains the application focus.
*
* A special case is that the root element may be focused, yet does not
* receive the element focus and blur events. Instead a focus outline may be
* drawn around the document.
*
* Blur and focus events do not bubble as per the W3C DOM Events spec.
