Honest, guv, it's not a feature - it's a tightly integrated
package of undo system cleanups and fixes.
NEW FILES:
* app/undo_history.c: window showing recent undo (and redo) steps
available.
* app/undo_types.h: broken out of undo.h to fix circular includes.
MODIFIED FILES:
* app/Makefile.am: compile undo_history.c
* app/channel.h: use enum for channel undo type, not just magic
numbers.
* app/layer.h: same for layer undos.
* app/commands.c: edit_show_undo_history_cmd_callback() function to
pull up undo history window.
* app/commands.h: prototype for above.
* app/gdisplay.c: make undo / redo menu items sensitive according
to whether they would do anything. Would be easy to change
the text to say what would be undone/redone, but I don't know
the GTK.
* app/gimpimage.c: new signal emitted by gimage:
UNDO_EVENT. gimp_image_undo_event() function to emit it.
* app/gimpimage.h: prototype for above.
* app/gimpimageP.h: pushing_undo_group member is now an undo_type,
not an int. Keep undo history widget here too (if created).
* app/menus.c: add "Edit/Undo history..." to image menu.
* app/undo.c: new types: enums undo_type and undo_state rather than
ints and magic numbers. All undo_pop_* and undo_free_*
functions made static. New static function
undo_type_to_name(). Issue undo event signals on various
important events (eg undo pushed, undo popped etc).
undo_push() now takes a "dirties_image" arg to say whether
image should be dirtied. Layer moves now dirty the image. A
couple of g_return_if_fails () on undo_pop and undo_redo to
assert we're not in the middle of an undo group.
undo_get_{undo,redo}_name() to peek at names of top items on
undo and redo stacks resp. undo_map_over_{undo,redo}_stack()
to run a function for each item or group on stack. Layer and
channel undos use symbolic names rather than 0 or 1. Array
mapping undo types to names.
* app/undo.h: split out undo types to undo_types.h. Prototypes
for functions described above. undo_event_t enum.
undo_history_new() prototype lives here too.
Random other fixes:
* app/gimpdrawable.c
* app/image_render.c: default labels in switches to keep egcs happy.
* app/nav_window.c: some fixes to (sort of) cope with image res !=
screen res. Still needs work to handle non-square pixels
properly.
* app/paths_dialog.c: bad idea to call gimp_image_dirty()
directly. Even though it's currently commented out.

Dirty flag now correct in all cases. Can be displayed in image
window title too. See NOTE near gimp_image_dirty() for details.
* app/fileops.c: gimp_image_clean_all() after reverting an image.
* app/gdisplay.c: register handlers for gimage dirty and clean
signals to update image title. New image-title-format
expansion: %Dx expands to x if the image is dirty.
* app/gdisplay_ops.c: gimage->dirty flags != 0 is the correct
condition to test to see if an image is dirty.
* app/gimpdrawable.c: gimp_image_dirty() should never be called
except from an undo_push_* function. Call
undo_push_cantundo() if you want to dirty the image but can't
be bothered writing an undo handler (be ashamed of yourself!).
* app/gimpimage.c: new gimage signal: clean. Emitted when an undo
operation takes place. Gimage changes when either dirty or
clean is emitted, so if you need to update previews etc, look
for both! Move group_count into gimage structure, since
leaving it as a static in undo.c is bad if two undo groups are
started on different images at the same time. More changes
of gimp_image_dirty() to undo_push_cantundo()
(parasite-related, plus layer moves). See the NOTE on dirty
counter near gimp_image_dirty() for the full story.
gimp_image_dirty() and gimp_image_clean() simplified - counter
can go negative.
* app/gimpimageP.h: group_count moved from undo.c
* app/layers_dialog.c: push undo for layer name change, rather
than dirtying the image.
* app/undo.c: layer rename undo functions
added. undo_push_cantundo() convenience functions added.
group_count made per-gimage since everything else is. When
blowing away redo stack, make image infinitely dirty if redo
info contained file save point.
* app/undo.h: added undo_push_layer_rename() and
undo_push_cantundo().
* TODO: added idea for undo history window.
* pixmaps/qmasknosel.xpm
* pixmaps/qmasksel.xpm: Ugly pixmaps that tigert promised to replace
* app/channel.[ch]
* app/channel_cmds.c : made some of the private structures accessible
through exported functions to keep things a bit clean
* app/interface.c
* app/gdisplay.[ch]
* app/gimpimageP.h
* app/gimpimage.[ch]
* app/undo.[ch]: added qmasks
* app/Makefile.am
* app/qmask.[ch]: added new files for qmask support
* tools/pdbgen/pdb/channel.pdb: changed some channel stuff to keep
things a bit more private
* app/edit_selection.c: removed some nonfunctional code.
* app/paint_core.c: remove the alt toggles perfectmouse behaviour.
* app/paintbrush.c: when ctl (or alt) is held set the fg (or bg) color.
* app/gimpparasite.[ch]: made char *name parameters const.
* app/parasitelist.c: removed unused static variable.
* app/gimpdrawable.c, app/gimpimage.c, app/undo.[ch]: added
support for undoing parasite changes.
* libgimp/gimp.h, libgimp/gimpimage.c: added
gimp_undo_push_group_start and gimp_undo_push_group_end
* libgimp/parasite.[ch]: added undoable flag.
* plug-ins/gdyntext/font_selection.c: fixed c++ style comment.
* plug-ins/gdyntext/gdyntext.c: use the new undoable parasites.
* plug-ins/rcm/rcm_misc.c: arctg can't be inline because it is
used in other .c files
* plug-ins/waterselect/waterselect.c,
* plug-ins/rotators/rotators.c, app/tips_dialog.c, app/plug_in.c:
fixed some warnings
to detect if an image still exists, some things may, for now,
access freed images and break. This will be fixed once proper
destroy handlers are added.
