2000-01-27 Andy Hertzfeld <andy@eazel.com>
hooked zooming up to the background context menu; right now the canvas item
doesn't work at different zoom levels properly, which we'll fix soon.
* libnautilus/fm-directory-view.c,h:
enable zoom in and zoom out items and hooked them up to callback
added a bump_zoom_level slot, to be overriden by subclasses, which the zoom callback use
* libnautilus/fm-directory-view-icons.c:
added method for bump_zoom_index that calls the icon container to do the work
* libnautilus/gnome-icon-container-private.h:
added a private instance variable for zoom level
* libnautilus/gnome-icon-container.c,.h:
added methods for get_zoom_level and set_zoom_level

* libnautilus/gnome-icon-container.c:
