Ehsan Akhgari 8c296bbcd4 Bug 579517 - Part 1: Automated conversion of NSPR numeric types to stdint types in Gecko; r=bsmedberg 
This patch was generated by a script.  Here's the source of the script for
future reference:

function convert() {
echo "Converting $1 to $2..."
find . ! -wholename "*nsprpub*" \
       ! -wholename "*security/nss*" \
       ! -wholename "*/.hg*" \
       ! -wholename "obj-ff-dbg*" \
       ! -name nsXPCOMCID.h \
       ! -name prtypes.h \
         -type f \
      \( -iname "*.cpp" \

/*
* nsWindow derives from nsIWidget via nsBaseWindow. With the aid
* of a helper class (os2FrameWindow) and a subclass (nsChildWindow),
* it implements the functionality of both toplevel and child widgets.
*
* Top-level widgets (windows surrounded by a frame with a titlebar, etc.)
* are created when NS_WINDOW_CID is used to identify the type of object
* needed. Child widgets (windows that either are children of other windows
* or are popups such as menus) are created when NS_CHILD_CID is specified.
* Since Mozilla expects these to be different classes, NS_CHILD_CID is
* mapped to a subclass (nsChildWindow) which acts solely as a wrapper for
* nsWindow and adds no functionality.
*
* While most of the methods inherited from nsIWidget are generic, some
* apply only to toplevel widgets (e.g. setting a title or icon). The
* nature of toplevel windows on OS/2 with their separate frame & client
* windows introduces the need for additional toplevel-specific methods,
* as well as for special handling in otherwise generic methods.
*
* Rather than incorporating these toplevel functions into the body of
* the class, nsWindow delegates them to a helper class, os2FrameWindow.
* An instance of this class is created when nsWindow is told to create
* a toplevel native window and is destroyed in nsWindow's destructor.
* The class's methods operate exclusively on the frame window and never
* deal with the frame's client other than to create it. Similarly,
* nsWindow never operates on frame windows except for a few trivial
* methods (e.g. Enable()). Neither class accesses the other's data
* though, of necessity, both call the other's methods.
