(gimp_display_shell_scale): Take a GimpZoomFocus parameter and

zoom focus point. For all other zooming, continue to use the
best-guess method.

Further work for completing bug #362915 that makes changes to the
image size (e.g when cropping) be much more nicely handled by
display shell.
* app/core/gimpimage.[ch]: Add new signal
GimpImage::size-changed-detailed that is emited whenever
GimpViewable::size-changed is. The new signal provides additional
information, namely the previous origin relative to the current
origin. Cliens choose what specific signal to listen to depending
on how much info they need.
* app/display/gimpdisplayshell-handlers.c: Connect to
GimpImage::size-changed-detailed instead of
GimpViewable::size-changed since the shell wants information about
the previous image origin.
(gimp_display_shell_resolution_changed_handler): Use
gimp_display_shell_scale_resize() instead to avoid display
garbage.
* app/display/gimpdisplayshell-scale.[ch]: Add new utility
function gimp_display_shell_center_image_on_next_size_allocate().
* app/display/gimpdisplayshell-scroll.[ch]
(gimp_display_shell_handle_size_changed_detailed): New function
that replaces logic in gimp_display_shell_handle_size_changed and
that takes previous-origin of the image into account and adjusts
the offset so that the image content that remains doesn't move. If
the window is resized on image resize, just center the image
afterwards.
* app/core/gimpimage-undo-push.[ch]
(gimp_image_undo_push_image_size): Add previous-origin paremeters.
* app/core/gimpimageundo.[ch]: Add and manage previous-origin
properties so that the display shell offset can be appropriately
adjusted also when undoing.
* app/core/gimpundo.h
* app/core/gimpimage-undo.c: Add previous_origin members to the
undo accumulator and emit that information when the size of the
image changes due to the undo.
* app/core/gimpimage-crop.c (gimp_image_crop)
* app/core/gimpimage-scale.c (gimp_image_scale)
* app/core/gimpimage-rotate.c (gimp_image_rotate)
* app/core/gimpimage-resize.c (gimp_image_resize_with_layers):
Supply information about the previous-origin of the image to the
size-changed signals and the undo system.

Never shrink the empty display when filling it, only grow:

grow_only" parameters to shrink_wrap() APIs which restricts
resizing of the window to growing.
* app/display/gimpdisplayshell-scale.[ch]

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-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.
