-it is active.  MINIBUF neither t nor nil means not to count the
-minibuffer even if it is active.

-Several frames may share a single minibuffer; if the minibuffer
-counts, all windows on all frames that share that minibuffer count
-too.  Therefore, when a separate minibuffer frame is active,
-`walk-windows' includes the windows in the frame from which you
-entered the minibuffer, as well as the minibuffer window.  But if the
-minibuffer does not count, only windows from WINDOW's frame count.
-
-Optional third arg ALL-FRAMES t means include windows on all frames.
-ALL-FRAMES nil or omitted means cycle within the frames as specified
-above.  ALL-FRAMES = `visible' means include windows on all visible frames.
-ALL-FRAMES = 0 means include windows on all visible and iconified frames.
