This was actually more of a feathering feature I added earlier, and we
already have a function for that: gimp_gegl_apply_feather(). This is
using a gaussian blur, just as what I was doing anyway. This commit also
adds the "Feather Radius" scale, similar to other tools with the
"Feather Edges". So that makes it consistent (and more useful as you can
adapt to your needs).

… Bucket Fill tool options.
This will provide feedback when the line art closure is being computed,
which may be useful on big images where it may take some time. Otherwise
painter may be left hanging without knowing what takes time.

Additionally to sample merge and active layer, now we can only use the
layer above or below the active layer as line art source.
The line art fill is meant to work on drawing lines. Though sample merge
still is ok in many cases, the more you fill with colors, the more the
line art computation becomes unecessarily complex. Also when you use a
lot of layers with some of them already filled with colors, it makes it
impossible to colorize some line art zones with the tool. Moreover you
just don't want to have to hide every layers out there to colorize one
layer (especially background layers and such as you may want to see the
result with your background).
Thus we want to be able to set the source as a unique layer, while it
not being necessarily the active one (because you want lines and colors
on different layers). In this case, I am assuming that the color and the
line layers are next to each other (most common organization).

... in GimpBucketFillOptions for the line art algorithm.
Inside GimpLineArt, there are still 2 properties, but we don't show them
anymore in the Bucket Fill tool options. One of the main reason is
probably that it's hard to differentiate their usage. One is to close
with curved lines, the other with straight segments. Yet we don't
actually have any control on one or the other. All one knows is that you
can have "holes" in your drawing of a given size and you want them
close-like for filling. Only reason I can see to have 2 types of closure
is whether you'd want to totally disable one type of closure (then you
set it to 0). But this is a very limited reason for making the options
less understandable overall, IMO.
So for the time being, let's show up only a single option which sets
both properties in GimpLineArt. As patdavid says "it makes sense as a
first pass".
Also rename the option to shorter/simpler "Maximum gap length". Thanks
to patdavid and pippin for helping on figuring out this better label!
Finally I am bumping the default for the gaps to 100px. The original
values were ok for the basic small images used in demos, but not for
real life image where it was always too short (even 100px may still be
too short actually, but much better than the 20 and 60px from before!).

This was my initial choice, but the more I think about it, the less I am
sure this was the right choice. There was some common code (as I was
making a common composite bucket fill once the line art was generated),
but there is also a lot of different code and the functions were filled
of exception when we were doing a line art fill. Also though there is a
bit of color works (the way we decide whether a pixel is part of a
stroke or not, though currently this is basic grayscale threshold), this
is really not the same as other criterions. In particular this was made
obvious on the Select by Color tool where the line art criterion was
completely meaningless and would have had to be opted-out!
This commit split a bit the code. Instead of finding the line art in the
criterion list, I add a third choice to the "Fill whole selection"/"Fill
similar colors" radio. In turn I create a new GimpBucketFillArea type
with the 3 choices, and remove line art value from GimpSelectCriterion.
I am not fully happy yet of this code, as it creates a bit of duplicate
code, and I would appreciate to move some code away from gimpdrawable-*
and gimppickable-* files. This may happen later. I break the work in
pieces to not get too messy.
Also this removes access to the smart colorization from the API, but
that's probably ok as I prefer to not freeze options too early in the
process since API needs to be stable. Probably we should get a concept
of experimental API.

When flooding the line art, we may overflood it in sample merge (which
would use color in the line art computation). And if having all colors
on the same layer, this would go over other colors (making the wrong
impression that the line art leaked).
This new option is mostly to keep some control over the mask growth.
Usually a few pixels is enough for most styles of drawing (though we
could technically allow for very wide strokes).
(cherry picked from commit eb042e6c87)
Since commit b00037b850, erosion size is not used anymore, as this step
has been removed, and the end point detection now uses local thickness
of strokes instead.
(cherry picked from commit 3f58a38574)
I have not added all the options for this new tool yet, but this sets
the base. I also added a bit of TODO for several places where we need to
make it settable, in particular the fuzzy select tool, but also simply
PDB calls (this will need to be a PDB context settings.
Maybe also I will want to make some LineArtOptions struct in order not
to have infinite list of parameters to functions. And at some point, it
may also be worth splitting a bit process with other type of
selection/fill (since they barely share any settings anyway).
Finally I take the opportunity to document a little more the parameters
to gimp_lineart_close(), which can still be improved later (I should
have documented these straight away when I re-implemented this all from
G'Mic code, as I am a bit fuzzy on some details now and will need to
re-understand code).

...when threshold > 0
Add an "Antialias" toggle to the bucket fill options and set it on the
GimpFillOptions. In gimp_drawable_bucket_fill(), pass it to
gimp_pickable_contiguous_region_by_seed() instead of always defaulting
to TRUE.
The position of the toggle and its huge tooltip may need some
adjustment.
When checked, diagonally neighboring pixels are considered connected
when calculating the affected area.
This commit also adds a corresponding diagonal_neighbors parameter to
gimp_drawable_bucket_fill(), and modifies the callers, other than the
bucket fill tool, to pass FALSE for this parameter, to retain the
current behavior.

Re-enabled filling the whole selection using the bucket fill
tool. Fixes bug #132649.
* app/tools/gimpbucketfilloptions.[ch]: added boolean property
"fill-selection" and a GUI for it.
* app/tools/gimpbucketfilltool.c: changed accordingly.

* app/core/gimpcontext.[ch]: simplified everything a lot by
merging the public GimpContextPropType enum with the internal
anonymous object property id enum. Removed the internal copy_prop
functions and handle property copying in a big switch() in
gimp_context_copy_property(). Removed the separate signal
connections for each property of the parent context and do the
same using a single "notify" handler. Emit "notify" signals all
over the place. Removed internal arrays which are no longer
needed due to enum merge and copy_property simplification.
Removed the array of signal names and use g_signal_name().
Removed gimp_context_unset_parent() and allow "parent" being NULL
in gimp_context_set_parent().
* app/tools/tool_manager.c
* app/widgets/gimpdevices.c: changed accordingly.

and return the main_vbox.

label here if NULL was passed as "options_gui_func". Attach the
options widget to the tool_options object using
