=for object Gtk2::ImageView::Nav Navigation window showing a thumbnailed overview of a Gtk2::ImageView.

=head1 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.
