request: make-frame-visible hook

[John J Foerch]

Hello,

   I make use of the [make-frame-visible] event in special-event-map in
order to update some emacs-related satus messages in my window manager.
However, with recent CVS emacs, another library called dframe has
registered a handler on this event.  My feature request is that there be
a hook for the make-frame-visible event, so that multiple handlers can
peacefully coexist.

  Thank you.
