DESCRIPTIONGtk2::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

Creates a new Gtk2::ImageView::Nav for showing thumbnails of the view.
The pixbuf is by default NULL.

Returns
a new Gtk2::ImageView::Nav showing the view.
$nav->grab
pixbuf = $nav->get_pixbuf

Gtk2::ImageView::Nav shows, or NULL if that pixbuf has not been created
yet.
