 28.12 Raising and Lowering Frames
 =================================
 
 Most window systems use a desktop metaphor.  Part of this metaphor is
 the idea that system-level windows (e.g., Emacs frames) are stacked in a
 notional third dimension perpendicular to the screen surface.  Where two
 overlap, the one higher up covers the one underneath.  You can “raise”
 or “lower” a frame using the functions ‘raise-frame’ and ‘lower-frame’.
 
  -- Command: raise-frame &optional frame
      This function raises frame FRAME (default, the selected frame).  If
      FRAME is invisible or iconified, this makes it visible.
 
  -- Command: lower-frame &optional frame
      This function lowers frame FRAME (default, the selected frame).
 
  -- User Option: minibuffer-auto-raise
      If this is non-‘nil’, activation of the minibuffer raises the frame
      that the minibuffer window is in.
 
    On window systems, you can also enable auto-raising (on frame
 selection) or auto-lowering (on frame deselection) using frame
 parameters.  Management Parameters.
 
    The concept of raising and lowering frames also applies to text
 terminal frames.  On each text terminal, only the top frame is displayed
 at any one time.
 
  -- Function: tty-top-frame &optional terminal
      This function returns the top frame on TERMINAL.  TERMINAL should
      be a terminal object, a frame (meaning that frame’s terminal), or
      ‘nil’ (meaning the selected frame’s terminal).  If it does not
      refer to a text terminal, the return value is ‘nil’.
