In gimp_image_merge_layers() -- the internal function used by the
various layer-merging/flattenning functions -- process the merged-
layer graph in chunks, using gimp_gegl_apply_operation(), instead
of in one go, using gegl_node_blit_buffer(). Processing in chunks
better utilizes the cache, since it reduces the size of
intermediate buffers, reducing the chances of hitting the swap when
merging large images (see, for example, issue #3012.)
Additionally, this allows us to show progress indication. Have the
relevant gimpimage-merge functions take a GimpProgress, and pass it
down to gimp_image_merge_layers(). Adapt all callers.

Plug-ins are not prepared to handle high-precision brushes/
patterns, even when they're otherwise aware of high-precision
drawables, so make sure to always use compat formats when
communicating brush/pattern data to plug-ins.
Allowing plug-ins to handle high-precision brush/pattern data would
require some additional API.

If you click on a zone filled in several visible layers, you don't
necessarily want the top layer. You may want one below. With this
change, as long as you hold alt, you will loop through all candidate
layers from top to bottom (then looping back top when reaching the
bottom).
In a first alt-click, you will always end up to the top candidate.

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.

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.

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).
(cherry picked from commit 6bec0bc82d)
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)
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.
(cherry picked from commit 3467acf096)
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).
(cherry picked from commit 824af12438)
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.

Add a gimp-register-file-handler-priority procedure, which can be
used to set the priority of a file-handler procedure. When more
than one file-handler procedure matches a file, the procedure with
the lowest priority is used; if more than one procedure has the
lowest priority, it is unspecified which one of them is used. The
default priority of file-handler procedures is 0.
Add the necessary plumbing (plus some fixes) to the plug-in manager
to handle file-handler priorities. In particular, use two
different lists for each type of file-handler procedures: one meant
for searching, and is sorted according to priority, and one meant
for display, and is sorted alphabetically.

Use gimp_babl_is_valid(), added in the previous commit, to validate
image-type/precision combinations in various functions.
(cherry picked from commit 49ca383fa4)
Instead just transform the measurement extremities appropriately to
still map to the same points.
To do so, I also added out parameters to gimp_image_resize_to_layers()
so that calling code can get offsets from old origin (as well as new
image dimensions).
(cherry picked from commit d56a8d439e)
Use gimp_fonts_wait(), added in the previous commit, to wait for
fonts to finish loading before operations that depend on font
availability. In particular, this includes font- and text-related
PDB functions, and text-layer rendering.
Fonts should not be blocking startup as this provides a very bad
experience when people have a lot of fonts. This was experienced even
more on Windows where loading time are often excessively long.
We were already running font loading in a thread, yet were still
blocking startup (thread was only so that the loading status GUI could
get updated as a feedback). Now we will only start loading and proceed
directly to next steps.
While fonts are not loaded, the text tool will not be usable, yet all
other activities can be performed.

so plug-ins cannot thaw what they haven't frozen, and the code
can clean up frozen stuff left behind by crashed or broken plug-ins.
Also redo the cleanup code so it only keeps track of the undo group
counts and freeze counts of what *this* GimpPlugInProcFrame did
itself. That should make it even stricter against broken code that
could mess up internals.
These procedures freeze/thaw the corresponding containers of the
image, allowing plug-ins that perform many changes affecting any of
these containers to suppress updates to the corresponding dialogs,
significantly improving performance.
We were only able to translate selections and layers (bot not channels
and paths) via the PDB, this new procedure fixes that. Deprecation of
old API and some more transform consistency to follow...
In the gimp-channel-combine-masks PDB wrapper, only push an undo step
if the modified channel is attached to an image. It's a completely
reasonable use case to combine unattached channels.
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.
