With the new API introduced int d1c4457f,
we next need to port all plug-ins using
the argument macros to functions.
This will allow us to remove the macros
as part of the 3.0 API clean-up.
- Removing useless or redundant code.
- Simplifying various logics.
- Using GimpResource directly in temporary PDB procedures, not resource names.
- Better cleanup of the core resource chooser when the plug-in dialog quits (we
need it to ask core to close also any visible resource chooser dialog).
- Replace the "Close" button by more common OK/Cancel. In particular, the
GimpPdbDialog now properly keeps track of the initial object and when hitting
"Cancel" (or Escape key), this initial object is set back.
- Clean up some of the comments, especially when the code is self explanatory.
There is still much more to clean and improve, but it's a first welcome step.
Brush, font, gradient, palette and pattern choices are currently chosen through
a dialog created by the core, which then returns the user choice to the calling
plug-in. This has the unfortunate consequence of having a pile of likely at
least 3 windows (main GIMP window by core process, plug-in window by plug-in
process, then the choice popup by the core process) shared in 2 processes, which
often end up under each other and that's messy. Even more as the choice popup is
kinda expected to be like a sub-part of the plug-in dialog.
So anyway, now the plug-in can send its window handle to the core so that the
resource choice dialog ends up always above the plug-in dialog.
Of course, it will always work only on platforms where we have working
inter-process transient support.
The one in GimpResourceSelect is a very nice example of why using config objects
is much nicer, getting arguments by their name instead of an index (which in
this case had to be tracked down by a private function to handle different
cases).
Much like for images and items. Change the PDB to transmit IDs
instead of names for brush, pattern etc. and refactor a whole
lot of libgimp code to deal with it.
modified: libgimp/gimpplugin-private.h
GLib has a specific type for byte arrays: `GBytes` (and it's underlying
GType `G_TYPE_BYTES`).
By using this type, we can avoid having a `GimpUint8Array` which is a
bit cumbersome to use for both the C API, as well as bindings. By using
`GBytes`, we allow other languages to pass on byte arrays 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 byte arrays
in other C/GLib based code (and not having 2 different types to denote
the same thing).

Simplifies chooser widgets (e.g. GimpBrushSelect) by eliminating attributes (e.g. opacity) of chosen resource.
See #8745, but this commit fixes that by first refactoring the code.
Refactors GUI widgets (e.g. GimpBrushSelectButton and GimpBrushSelect etc.)
Refactor by "Extract class" GimpResourceSelectButton from GimpBrushSelectButton etc.
This moves common code into an inherited class (formerly called GimpSelectButton)
but the subclasses still exist.
The subclasses mainly just do drawing now.
Refactor by "Extract module" GimpResourceSelect from GimpBrushSelect etc.
Moves common code into one file, generic at runtime on type of GimpResource,
that is, the new code dispatches on type i.e. switch statements.
In the future, when core is changed some of that can be deleted.
The files gimpbrushselect.[c,h] etc. are deleted.
The module adapts the API from core to the API of callbacks to libgimp.
Note that core is running the resource chooser (select) widgets remotely.
Core is still calling back over the wire via PDB with more attributes
than necessary.
The new design gets the attributes from the resource themselves,
instead of receiving them from core callback.
The libgimp side adapts by discarding unneeded attributes.
In the future, core (running choosers for plugins) can be simplified also.
Fix gimp_prop_chooser_brush_new same as other resources.
Finish changes, and clean style.
