2008-03-18  Michael Natterer  <mitch@gimp.org>

	First draft of the "no image open" window, which is implemented as
	a display without image (a view with NULL model). Didn't change
	the display's appearance yet so I can first make sure the display
	without image works properly in all details before hiding these
	details.

	* app/core/gimp-gui.[ch]: add "gimp" parameter to display_create()
	and allow "image" to be NULL.

	* app/core/gimpcontext.c (gimp_context_real_set_display): a
	display's image can be NULL now.

	* app/display/gimpdisplay.[ch]: add Gimp and GimpDisplayConfig
	members.  Add Gimp parameter to gimp_display_shell_new(). Changed
	gimp_display_reconnect() to gimp_display_set_image() and allow to
	set a NULL image.

	* app/gui/gui-vtable.c (gui_display_create): if there is a single
	display without an image, call gimp_display_set_image() on that
	display instead of creating a new one.

	* app/display/gimpdisplayshell-close.c: if the last display is
	closed, don't close it but make it empty. Factored out that code
	to gimp_display_shell_really_close().

	* app/display/gimpdisplayshell-dnd.c: when dropping uris on an
	empty display, open the first one into that display and the other
	ones as layers of the newly opened image. This is consistent with
	dropping on an existing image but maybe needs some discussion.

	* app/display/gimpdisplayshell-callbacks.c: bail out early in the
	tool event callback so tools never have to deal with empty
	displays. In expose(), draw the drop zone on the empty display.

	* app/display/gimpdisplayshell-title.c: set the empty display's
	title to "Gimp - Drop Files".

	* app/display/gimpdisplay-foreach.c
	* app/display/gimpdisplay-handlers.c
	* app/display/gimpdisplayshell-appearance.c
	* app/display/gimpdisplayshell-autoscroll.c
	* app/display/gimpdisplayshell-callbacks.c
	* app/display/gimpdisplayshell-cursor.c
	* app/display/gimpdisplayshell-dnd.c
	* app/display/gimpdisplayshell-draw.c
	* app/display/gimpdisplayshell-filter-dialog.c
	* app/display/gimpdisplayshell-handlers.c
	* app/display/gimpdisplayshell-layer-select.c
	* app/display/gimpdisplayshell-preview.c
	* app/display/gimpdisplayshell-render.c
	* app/display/gimpdisplayshell-scale.c
	* app/display/gimpdisplayshell-scroll.c
	* app/display/gimpdisplayshell-selection.c
	* app/display/gimpdisplayshell-title.c
	* app/display/gimpdisplayshell.c
	* app/display/gimpnavigationeditor.c
	* app/display/gimpstatusbar.c: use display->gimp and
	display->config instead of going via the image. Guard against
	empty displays in some few places (most places can't be
	called). Where needed, use the canvas' dimensions instead of the
	image's dimensions so scroll offsets and scrollbars still have
	sane values instead of the last image's ones.

	* app/actions/actions.c (action_data_get_gimp)
	(action_data_get_context): use display->gimp instead of
	display->image->gimp.

	* app/actions/edit-commands.c (edit_paste_cmd_callback): redirect
	to "paste as new" if there is an empty display.

	* app/actions/tools-commands.c (tools_select_cmd_callback): don't
	initialize the new tool on an empty display.

	* app/actions/view-actions.c (view_actions_update): changed lots
	of sensitivity settings to be insensitive when there is no image
	(instead of no display).

	* app/actions/view-commands.c: use the display's config object
	instead of gimp's.
