* This is a utility procedure invoked by focus-management code. It
* exists because of the extra wrapper windows that exist under
* Unix; its job is to map from wrapper windows to the
* corresponding toplevel windows. On PCs and Macs there are no
* wrapper windows so no mapping is necessary; this procedure just
* determines whether a window is a toplevel or not.
*
* Results:
* If winPtr is a toplevel window, returns the pointer to the
* window; otherwise returns NULL.
*
* Side effects:
* None.
