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).
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.
Same as previous commit: by default the new API will be used. But if a
plug-in builds with GIMP_DEPRECATED_REPLACE_NEW_API macro, then the same
function names will call the old API with ids.
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
Change gimp_pixbuf_create_buffer() to copy the pixels if a linear
buffer cannot be created. Add functions that convert between
GimpTempBuf and GdkPixbuf. Fix users of gimp_pixbuf_create_buffer()
to make the least possible copies. Patch modified by Mitch.
Move the pixbuf layer and image thumbnail function from libgimpui to
libgimp and move gimp_layer_new_from_pixbuf() to gimplayer.[ch] where
it belongs. Change gimp-2.0.pc accordingly, adapt plug-in Makefiles
and update devel-docs.

* 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.
