DESCRIPTION
       Gtk2::ImageView::Nav is a popup window that shows a downscaled preview
       of the pixbuf that Gtk2::ImageView is showing. The user can drag	around
       a rectangle which indicates the current view of the image.

       This class is used by Gtk2::ImageView::ScrollWin	itself.	It is probably
       not very	useful for clients of this library.

       Gtk2::ImageView::Nav has	the same keybindings that Gtk2::ImageView has.
       All keypresses that it receives are passed along	to the view.

METHODS
   widget = $view->new
       Returns a new Gtk2::ImageView::Nav for showing thumbnails of the	view.
       The pixbuf is by	default	undef.

   $nav->grab
   pixbuf = $nav->get_pixbuf
       Returns the downscaled pixbuf of	the views pixbuf that this
       Gtk2::ImageView::Nav shows, or undef if that pixbuf has not been
       created yet.

       The pixbuf is by	default	undef.

   $nav->release
   $nav->show_and_grab ($center_x, $center_y)
       o   $center_x (integer)

       o   $center_y (integer)

       Returns the Gtk2::ImageView::Nav	centered around	the point (center_x,
       center_y) and grab mouse	and keyboard events. The grab continues	until
       a button	release	event is received which	causes the widget to hide.

PROPERTIES
       'view' (Gtk2::ImageView : default undef : writable / construct-only)
