Now text layers are proper types, which means that the binding API will also be
nicer (e.g. `txt_layer.set_text('hello world')` in Python).
This commit also adds the param specs allowing to create plug-in procedures with
text layer parameters.
Finally it fixes the few calls in file-pdf-save (apparently the only plug-in
using specific text layer API right now) with explicit type conversion.
GLib has a specific type of NULL-terminated string arrays:
`G_TYPE_STRV`, which is the `GType` of `char**` aka `GStrv`.
By using this type, we can avoid having a `GimpStringArray` which is a
bit cumbersome to use for both the C API, as well as bindings. By using
`GStrv`, we allow other languages to pass on string lists as they are
used to, while the bindings will make sure to do the right thing.
In the end, it makes the API a little bit simpler for everyone, and
reduces confusion for people who are used to working with string arrays
in other C/GLib based code (and not having 2 different types to denote
the same thing).

Since it appeared with GLib 2.68.0, we could not change this until we
bumped the dependency which has only become possible a few days ago
(since Debian testing is our baseline for dependency bumps). Cf.
previous commit.
As this is a drop-in replacement (just a guint parameter changed to
gsize to avoid integer overflow), search-and-replace with:
> sed -i 's/g_memdup\>/g_memdup2/g' `grep -rIl 'g_memdup\>' *`
… followed by a few manual alignment tweaks when necessary.
This gets rid of the many deprecation warnings which we had lately when
building with a recent GLib version.
It isn't being used by any plug-in or any code in GIMP at all even.
Let's get rid of it while we can still break API, so we can cut down on
all the complexity of the gimp-param stuff a bit.
and in an attack of madness, changes almost all file plug-in
code to use GFile instead of filenames, which means passing
the GFile down to the bottom and get its filename at the very
end where it's actually needed.
In the generated libgimp wrappers, we can't return object arrays
from a call to GIMP_VALUES_DUP_OBJECT_ARRAY() because it returns
a deep copy and adds a reference to all objects, which the caller
would have to unref.
But we want a shallow (transfer container) copy because we don't want
libgimp proxy objects to be refed or unrefed by any user code.
Therefore, add a HACK that simply memdup()s and returns the
GimpObjectArray's array memory, and leaves the contained object
pointers alone.
GimpDisplay contains only the ID logic and the "gimp" and "config"
pointers, and lives in the core.
GimpDisplayImpl is a subclass and contains all the actual display
stuff. The subclass is only an implementation detail and doesn't
appear in any API.
Remove all hacks which pass displays as gpointer, GObject or
GimpObject through the core, or even lookup its type by name,
just use GimpDisplay.
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
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.
This means that all functions which were returning or taking as
parameter an image id (as gint32) are now taking a GimpImage object
instead.
The PDB is still passing around an id only over the wire. But we create
an object for plug-ins to work on.
This is quite a huge API break, but is probably the best bet for the
future quality. It will make nicer API instrospection (and nicer API in
binding), will fix the issues with pspec on GimpImageID in Python
bindings (which makes the current Python API unusable as soon as we need
to work on images, which is most of our plug-ins!), etc.
Also it will allow to use signals on images, which will be a great asset
when we will finally have bi-directionnal communications (i.e. plug-ins
would be able to connect to image changes, destructions, and whatnot).
Which return proper GParamSpecs. Incuding some useless testing code in
gimp_procedural_db_proc_info(), to make sure things work, will go away
again soon.
It never belonged inside "tools". Also rename its "pdb" subdirectory
to "groups". This had to happen before 2.10 so cherry-picking between
branches doesn't become a nightmare in the future.
