Place the rulers' origin at the top-left corner of the canvas
(screen space) bounding box, and set their scale to the image-
space scale along the screen-space horizontal/vertical directions
(in other words, measuring a distance using the rulers should
give the same results as the measure tool; note that rotation
comes into play here only when the horizontal and vertical
image or screen resolutions are different, since otherwise the
scale is direction invariant.)
Make scrollbar step match ruler step under the new behavior.
...several different zooms tiled together
In gimp_display_shell_scale() don't shortcut things in the case where
we resize the window, but call gimp_display_shell_scale_resize() like
all other scaling functions do in the end.
gimp_display_shell_scale_to(): calculate the point that should not
move with GimpDisplayShell's untransform/transform functions before
and after scaling, then scroll to the right point. Just using the
scale functions doesn't work any longer when a rotation is
active. Other functions are affected too, but this most important
issue can be fixed by fixing just this function.
and get rid of the brainfuck idea that app/ has to use _gimp_unit_foo()
functions, passing a gimp pointer. Instead, simply use the libgimpbase
API all over the place. Should we ever allow more than one gimp instance,
they will simply have to share one unit database.
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.
The new function does the right thing, unlike get_toplevel() which
returns the shell itself if it is not in a window. Check the return
value of get_window() for being non-NULL.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

zoom-focus better
* app/display/display-enums.h: Added
GIMP_ZOOM_FOCUS_RETAIN_CENTERING_ELSE_BEST_GUESS.
* app/display/gimpdisplayshell-scale.c
(gimp_display_shell_scale_get_zoom_focus): Take the new enum into
account; if the image is centered, keep it centered, else use the
best-guess method.
* app/actions/view-commands.c (view_zoom_explicit_cmd_callback):
Use the new enum for explicit zooming.
* app/display/display-enums.c: Regenerated.
svn path=/trunk/; revision=27653
* app/display/gimpdisplayshell-scale.c (gimp_display_shell_scale):
Also take the image center and not only the zoom focus point into
account when deciding whether or not to center the image after
zoom.

* app/display/gimpdisplayshell-scroll.[ch]: removed function
gimp_display_shell_scroll_get_scaled_viewport_offset() as it was
only returning -shell->offset_x and -shell->offset_y and it
started to show up in profiles.
* app/display/gimpdisplayshell-draw.c
* app/display/gimpdisplayshell-transform.c
* app/display/gimpdisplayshell-scale.c: use the shell offsets
directly.

* app/display/gimpdisplayshell-scale.c
(gimp_display_shell_scale_update_rulers): Avoid critical warnings
when converting an image window with a unit other than pixels into
a the empty image window. Probably fixes some of the crashes
reported by Windows users.
svn path=/trunk/; revision=27586
* app/display/gimpdisplayshell-scale.c
* app/display/gimpdisplayshell-callbacks.c: Fix calls to
gimp_display_shell_scaled() when Resize window on zoom is enabled.
