86b9738286 app: do not make line art bucket fill a GimpSelectCriterion anymore.
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.

a68524d43b app: reorganize the line art code inside a GimpLineArt object.
The code was too much spread out, in core and tool code, and also it was
made too specific to fill. I'll want to reuse this code at least in the
fuzzy select tool. This will avoid code duplication, and also make this
new process more self-contained and simpler to review later (the
algorithm also has a lot of settings and it is much cleaner to have them
as properties rather than passing these as parameters through many
functions).

The refactoring may not be finished; that's at least a first step.

b1236403cf app: add the segment and spline max length options for line art.
We can't just hardcode this. On huge images in particular, you'll want
to increase this value.

4fe5dc5d42 app: radius map actually not useful during smart colorization grow step.
The distance map has all the information we need already. Also we will
actually grow up to the max radius pixel (middle pixel of a stroke).
After discussing with Aryeom, we realized it was better to fill a stroke
fully (for cases of overflowing, I already added the "Maximum growing
size" property anyway).

b00580d4b1 app: add "line-art-max-grow" property to the bucket fill options.
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).

e5bea42b6f app: replace gegl:watershed-transform with custom algorithm.
We don't really need to flow every line art pixel and this new
implementation is simpler (because we don't actually need over-featured
watershedding), and a lot lot faster, making the line art bucket fill
now very reactive.
For this, I am keeping the computed distance map, as well as local
thickness map around to be used when flooding the line art pixels
(basically I try to flood half the stroke thickness).

Note that there are still some issues with this new implementation as it
doesn't properly flood yet created (i.e. invisible) splines and
segments, and in particular the ones between 2 colored sections. I am
going to fix this next.

6155889315 app: remove now useless erosion size option.
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.

6b1d7969ed app: edit the bucket fill tool options with new line art options.
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).

32f0a49ecc app: compute line art in advance.
Right now, this is mostly meaningless as it is still done sequentially.
But I am mostly preparing the field to pre-compute the line art as
background thread.

436e53d390 pdb: improve docs about which procedures are affected by context settings
Also add some double blank lines so they show up as single blank
lines in the generated docs, which improves readablility.

50536e1c38 Bug 795230 - Rename Blend tool and provide PDB compatibility
Add new PDB group "drawable_edit" which has all procedures from the
"edit" group which are not cut/copy/paste.

The new group's procedures don't have opacity, paint_mode
etc. arguments but take them from the context instead. Unlike the old
gimp-edit-fill, gimp-drawable-edit-fill now uses the context's opacity
and paint_mode.

The new gimp-drawable-edit-gradient-fill procedure uses even more
context properties which are also newly added with this commit
(gradient_color_space, gradient_repeat_mode, gradient_reverse).

And some cleanup in context.pdb.

This is still WIP, nothing in the edit group is depcreated yet.
