Replaced the concept of having a boolean indicating if an undo
step dirties the image by a bitfield indicating which parts
of the image are dirtied:
* app/core/core-enums.[ch]: reordered two values in enum
GimpUndoType, added GIMP_DIRTY_IMAGE_SIZE to enum GimpDirtyMask.
The values of GimpDirtyMask are still questionable and will
probably change...
* app/core/gimpimage.[ch]: removed signal "undo_start" and added
a GimpDirtyMask parameter to the "dirty" and "clean" signals.
* app/core/gimpimage-undo.[ch] (gimp_image_undo_push): replaced
"gboolean dirties_image" by "GimpDirtyMask dirty_mask" and pass
it to gimp_image_dirty().
(gimp_image_undo_group_start): added *ugly* code which tries to
figure GimpDirtyMask from the group's GimpUndoType and store it in
the GimpUndoGroup. Call gimp_image_dirty() instead of the removed
gimp_image_undo_start(). This means the undo group now dirties the
image just like one of its undo steps, but that's no problem since
undoing cleans it in the same way.
* app/core/gimpundo.[ch]: s/dirties_image/dirty_mask/g
(gimp_undo_pop): emit clean/dirty signals *before* performing the
actual undo step so listeners can detach from the image before it
is changed by undo.
* app/core/gimpimage-undo-push.c (gimp_image_undo_push_*): pass a
GimpDirtyMask instead of TRUE/FALSE to gimp_image_undo_push().
* app/core/gimpimagemap.[ch]: removed "gboolean interactive"
because it makes no sense to use GimpImageMap noninteractively.
Don't freeze()/thaw() undo while the image_map is active which
fixes many ways of trashing the image's undo state but probably
introduces new ways of doing evil things.
* app/display/gimpdisplay-foreach.c
* app/display/gimpdisplayshell-handlers.c: changed according
to the GimpImage::clean()/dirty() signal changes. Small fixes
in the quit dialog's dirty image container.
* app/tools/gimptoolcontrol.[ch]: added member and API to
set/get the dirty_mask.
* app/tools/gimpcroptool.c
* app/tools/gimpimagemaptool.c
* app/tools/gimpiscissorstool.c
* app/tools/gimptexttool.c
* app/tools/gimptransformtool.c: whenever setting "preserve" to
FALSE, also set a "dirty_mask" which specifies on which image
changes the tool wants to be canceled.
* app/tools/tool_manager.c: removed "undo_start" connection and
connect to both "dirty" *and* "clean" to check if the active_tool
needs to be canceled. Cancel the tool only if the dirty_mask
passed in the signal has common bits with the tool's dirty_mask.
Fixes bug #109561 and probably opens some new ones...
