Fixed bug #305. CLicking in center of zoom control does not change zoom

2000-06-13  Gene Z. Ragan  <gzr@eazel.com>

	Fixed bug #305.  CLicking in center of zoom control
	does not change zoom level.

	Clicking in the center of the zoom control emits a ZOOM_DEFAULT
	signal.  It is up to each view that connects to this signal
	to determine what is the default zoom setting.  Right now, all
	views are using NAUTILUS_ZOOM_LEVEL_STANDARD.  This could be
	changed to a zoom level better suited for the view.

	* libnautilus/nautilus-view-component.idl:
	Added zoom_default interface.

	* libnautilus/nautilus-zoomable.c:
	* libnautilus/nautilus-zoomable.h:
	(impl_Nautilus_Zoomable_zoom_default)
	Implimetation function of zoom_default interface

	(nautilus_zoomable_initialize_class):
	Set up new ZOOM_DEFAULT signal.

	* src/file-manager/fm-directory-view.c:
	* src/file-manager/fm-directory-view.h:
	(fm_directory_view_initialize_class),
	(fm_directory_view_initialize), (zoom_out_callback),
	(zoom_default_callback), (zoomable_zoom_default_callback),
	(fm_directory_view_restore_default_zoom_level):
	New functions to enable zoom to default.

	* src/file-manager/fm-icon-view.c:
	(fm_icon_view_initialize_class):
	Override zoom_default method.

	(fm_icon_view_restore_default_zoom_level),
	New function to enable zoom to default.

	* src/file-manager/fm-list-view.c:
	(fm_list_view_initialize_class):
	Override zoom_default method.

	(fm_list_view_restore_default_zoom_level):
	New function to enable zoom to default.

	* src/file-manager/fm-properties-window.c: (create_basic_page):

	* src/nautilus-view-frame.c:
	* src/nautilus-view-frame.h:
	(nautilus_view_frame_zoom_default):
	New signal handling callback
