When Control-Button2-Zooming, remember the start point, pass it to
gimp_display_shell_scale_drag() and force gimp_display_shell_scale()
to zoom around that point by passing GIMP_ZOOM_FOCUS_POINTER and
faking the point using gimp_display_shell_push_zoom_focus_pointer_pos().
- Fix gimp_scroll_adjustment_values() for smooth scroll events
- Set GDK_SMOOTH_SCROLL_MASK on all widgets where we set GDK_SCROLL_MASK
- Add GIMP_ZOOM_SMOOTH to enum GimpZoomType
- Add "gdouble delta" to gimp_zoom_model_step()
- Change the meaning of the "scale" parameter to "scale or delta" in
all functions that take GimpZoomType and a scale factor.
... _even at low zoom levels_
Pass GIMP_ZOOM_FOCUS_POINTER to gimp_display_shell_scale() when
wheel-scrolling, and change the scaling code to really honor
GIMP_ZOOM_FOCUS_POINTER and not apply magic image centering.
This keep the same point centered under the mouse for wheel-scrolling
and the zoom tool (== when the zooming is really triggered at a
certain mouse position).
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.
