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).
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.
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.
gimp-item-find-parasite -> gimp-item-get-parasite
gimp-item-list-parasites -> gimp-item-get-parasite-list
Also changed the signature of gimp-item-get-parasite-list's C wrapper
in libgimp to be sane.
and simply add them to the list of "compat_procs" which have a
replacement with identical signature. Move the libgimp C functions to
non-generated files.
that have a replacement with identical signature. Register them as
compat aliases with the PDB instead. Implement the libgimp API
manually, calling the new item functions.
