...to path.
Changes the names of
gimp_vectors_* () API to
gimp_path[s]_* (). Renames related files
to [path] instead of [vectors], along with
relevant enums and functions.
This commit renames the GimpVectors
object to GimpPath in both app/core and
in libgimp. It also renames the files
to gimppath.[ch] and updates the relevant
build and translation files.
There are still outstanding gimp_vectors_* ()
functions on the app side that need to be renamed
in a subsequent commit.
Also:
- renaming gimp_layer_group_new() to gimp_group_layer_new() in order to keep the
same name as in core code (i.e. GimpGroupLayer, not GimpLayerGroup).
- renaming gimp_image_merge_layer_group() to gimp_group_layer_merge()
- new functions: gimp_procedure_add_group_layer_argument(),
gimp_procedure_add_group_layer_aux_argument() and
gimp_procedure_add_group_layer_return_value().
This can be tested, e.g. in Python with these calls:
```py
i = Gimp.get_images()[0]
g = Gimp.GroupLayer.new(i, "hello")
i.insert_layer(g, None, 1)
g2 = Gimp.GroupLayer.new(i, "world")
i.insert_layer(g2, g, 1)
g.merge()
```
This was work started long ago, stored in an old stash which I finally
finish now! :-)
Same for gimp_procedure_add_aux_argument() and gimp_procedure_add_return_value().
We now have specific public functions for every supported type and it's
in fact much better to use them. The generic functions gave the feeling
that we could use any GParamSpec as procedure argument, whereas we in
fact depend on what the PDB support, and only these subtypes.
In order for Python plug-ins to be able
to create custom parameters like
GeglColor and GimpChoice, we need to
create actual functions rather than
using macros. A subsequent commit
will update all plug-ins to use them.
