First version of display rotation, inspired by gimp-painter.
The rotation always happens around the image's center.
The only "UI" for rotating is currently shift+middle-drag and
shift+space-drag. Control constrains the angle to 15 degrees
and is currently the only way to go back to "no rotation".
- adapt callbacks to ignore / not block events on offscreen children
- use GimpOverlayBox' scroll API which makes sure overlay children
don't scroll along
but also don't use its accessors because doing that would emit
"changed" multiple times when setting up an adjustment with multiple
utility functions. Instead, use g_object_set() and freeze/thaw
notification around all calls. g_object_thaw_notify() will make sure
"changed" is emitted if anything has changed since freezing.

* app/display/gimpdisplayshell-scroll.[ch]: removed function
gimp_display_shell_scroll_get_scaled_viewport_offset() as it was

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.

The following change is conceptually based on a patch by
Alexia Death and implements the core functionality for
bug #362915.

such a way that allows to scroll beyond the image border.

(gimp_display_shell_setup_vscrollbar_with_value): Put common
scrollbar range setup code here.
* app/display/gimpdisplayshell-scale.c
(gimp_display_shell_scale_setup): Use above helper functions for
setting up scrollbar range.
* app/display/gimpdisplayshell-callbacks.c: Handle adjustment of
the scrollbar range when they are about to change value.
* app/display/gimpdisplayshell.c: Always keep the scrollbar
steppers sensitive to user input.

* app/display/gimpdisplayshell-scroll.c:

gimp_display_shell_center_around_image_coordinate() since that is
easier to map to something sensible when we allow to scroll beyond
image border.
* app/display/gimpnavigationeditor.c
(gimp_navigation_editor_marker_changed): Adapt to the new
interface.

disp_[xy]offset based on the new offset_[xy].

* app/display/gimpdisplayshell-draw.c

* app/display/gimpdisplayshell-scroll.c
(gimp_display_shell_get_scaled_image_viewport_offset): New
function to replace any occurance of
shell->disp_[xy]offset - shell->offset_[xy]
that is just an implementation specific way of saying the same
thing.
* app/display/gimpdisplayshell-draw.c
* app/display/gimpdisplayshell-transform.c: Make the code less
implementation dependant by using the new function.
