which call gimp_item_get_by_id() and additionally check if the
returned item has the right type, and return NULL if not.
This is both shorter and more readable than
layer = GIMP_LAYER (gimp_item_get_by_id (id));
and additionally makes sure we don't cast e.g. a non-layer with
GIMP_LAYER(), which will give criticals but shouldn't, because the
wrong IDs can come from anywhere and are an input problem and not a
programming error (criticals are for programming errors).
Even when the function names may have stayed the same in most cases, the
API has changed. The "Since:" tag must therefore be bumped.
Also adding docs for gimp_drawable_get_sub_thumbnail_data() which had
none.
This means that images' ownership is not given to caller in particular.
libgimp will now keep a reference of all GimpImage-s it creates and
return this same reference if called again. It also means that you can
now compare images by pointer comparison (as 2 GimpImage objects
representing the same image ID will be equal).
Obviously as a side effect, gimp_image_list() is changed to (transfer
container) as you must only free the container now, not the elements.
Also various other functions creating new images are now (transfer none)
too.
Long-time plug-ins will have to be taken in consideration in a further
step (we currently never free GimpImage for destroyed images in
particular).
No need of is_id_arg() anymore in pdb/lib.pl. Let's reuse the {id}
value. Also I had to add an additional trick for GimpDisplay which we
will now generate as such in libgimp PDB files, but still need to show
as GimpObject on app/pdb/.
As previously, only the new classes and the PDB generation for a first
step.
I did the same trick with GIMP_DEPRECATED_REPLACE_NEW_API macro, apart
for some minor widget API to preview drawable, which I will fix right
away in our plug-ins.

* 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.

* libgimp/gimpbrushes.c
* libgimp/gimpgradients.c
* libgimp/gimpimage.c
* libgimp/gimplayer.c
* libgimp/gimppalette.c
* libgimp/gimppalettes.c
* libgimp/gimppatterns.c
* libgimp/gimpselection.c: also let all non-generated deprecated
functions see their declarations.
2004-11-16 Michael Natterer <mitch@gimp.org>
* tools/pdbgen/pdb/image.pdb
* tools/pdbgen/pdb/selection.pdb: entirely removed the deprecated
functions "selection_clear", "image_set_cmap" and "image_get_cmap".
* app/pdb/procedural_db.c: and added them to the compat hash table
because they have undeprecated replacements with identical
signature.
* libgimp/gimpselection.[ch]: added gimp_selection_clear() here
instead because we need the symbol in libgimp.
* app/pdb/image_cmds.c
* app/pdb/internal_procs.c
* app/pdb/selection_cmds.c
* libgimp/gimpselection_pdb.[ch]: regenerated.

Sven Neumann <sven@gimp.org>
Completed the new file structure. Yet only few of the _pdb.[ch]
files are based upon generated code and nothing is really
autogenerated...
* app/Makefile.am
* app/gdisplay_cmds.c -> app/display_cmds.c
* app/gimage_cmds.c -> app/image_cmds.c
* app/gimage_mask_cmds.c -> app/selection_cmds.c
* app/internal_procs.c: related change
* libgimp/Makefile.am
* libgimp/gimp.h
* libgimp/gimp_pdb.h
* libgimp/gimpdisplay_pdb.[ch]
* libgimp/gimpimage_pdb.[ch]
* libgimp/gimpselection_pdb.[ch]: replaced with code based on files
generated using pdbgen
* libgimp/gimpchannelops_pdb.[ch]
* libgimp/gimpcolor_pdb.[ch]
* libgimp/gimpedit_pdb.[ch]
* libgimp/gimpfloatingsel_pdb.[ch]
* libgimp/gimpgimprc_pdb.[ch]
* libgimp/gimptexttool_pdb.[ch]
* libgimp/gimptools_pdb.[ch]
* libgimp/gimpundo_pdb.[ch]: new files based on generated code
* libgimp/gimpgradientselect.[ch]
* libgimp/gimpimage.[ch]
* libgimp/gimpselection.[ch]: new files wrapping around the
autogenerated PDB wrappers as found in *_pdb.[ch]. This is necessary
since the number of parameters or their order is different from the
PDP calls.
* plug-ins/common/CEL.c: plugged memleak
* plug-ins/common/aa.c: removed compiler warning
* tools/pdbgen/Makefile.am
* tools/pdbgen/groups.pl
* tools/pdbgen/pdb/gdisplay.pdb -> display.pdb
* tools/pdbgen/pdb/gimage.pdb -> image.pdb
