when window positions aren't automatically saved.
Save "hide-docks" and "single-window-mode" in sessionrc instead of
gimprc, so a session layout is always saved either completely or not
at all. Also change "last-tip-shown" saving a bit so all three
session-saved gimprc properties are implemented the same.
Rememeber if image windows are opened because we want the
gimp_session_info_restore() code to run for the single-image window
once that code is in place.
In gimp_session_info_restore() there is code to create a dialog from a
session info. GimpSessionInfo lives in the widgets module. Thus we
can't add restoration code that depends on a higher level module. In
particular, we can't add code to restore docks in an GimpImageWindow
since GimpImageWindow lives in the display module. And we need such
code to be able to restore a single-window mode session.
Since dialogs are defined in the dialogs module, it makes sense to
also have the code that restores a dialog in that module.
So, add a 'restore_func' member to GimpRestoreDialogFunc of type
GimpRestoreDialogFunc and move the code there.
Add image_window boolean to GimpDialogFactoryEntry and rename
FOREIGN_NOT_HIDEABLE() to IMAGE_WINDOW(). We need to treat image
windows a bit special when we restore a single-window mode session.
Add "gboolean merge_active_group" to gimp_image_merge_visible_layers()
and pass FALSE from the PDB wrapper so plug-in invoked layer merging
always acts on the toplevel container as it did in 2.6. Do the same
when opening an image as layer.
Also, added a "Merge within active group only" toggle to the merge
layers dialog and pass it down to the core, but default to TRUE here
so.
We should handle import-URI and export-URI at a lower level so
e.g. the import URI is reset when gimp_dnd_xds_save_image() is
used.
This change also simplifies unit testing.
by integrating their label instead of requiring one externally. This
way we get rid of some more labels in the tool options. Also clean up
tool options further (add more spin scales, and some general
reordering and spacing cleanup).
because the packing options are different for GtkH/VBox and GtkBox
itself which is now instantiable. Instead, always use
gtk_box_pack_start() and specify expanding explicitely.
