Show an error message, and blink the layers-dialog lock-box, when
attempting to clear/cut a layer with a locked alpha channel.
(cherry picked from commit e967e5fa9e)
In gimp_drawable_edit_fill(), if the fill only affects the alpha
channel, and if the drawable has no alpha channel, or the alpha
channel is masked out, do nothing, instead of unnecessarily
performing the fill, which has no effect.

In gimp_gegl_apply_cached_operation(), intersect the cached rects
with the dest rect, so that we don't unnecessarily (if not
erroneously) copy cached regions outside the dest rect to the dest
buffer. This can happen when the op's applicator crop-rect changes
dynamically.

In the warp tool, set the drawable-filter's crop area to the
combined stroke bounds, so that, when comitting the tool, only this
area is processed, instead of the entire drawable area.
(cherry picked from commit e06c4643dc)
In GimpDrawableFilter, when updating the entire filter area, only
update the crop/preview area (as set by
gimp_drawable_filter_set_{crop,preview}()), instead of the entire
drawable.
(cherry picked from commit b846ffed19)
Add gimp_drawable_filter_set_crop(), which allows setting an output
crop rectangle for the filter; anything outside the rectangle
doesn't get filtered. The crop area is combined with the preview
area to determine the filtered area during preview, however, unlike
the preview area, the crop area remains in effect while committing
the filter.
Consequently, when merging a drawable filter, if the filter has a
crop, only process the cropped area.
(cherry picked from commit 5c27d14fdf)
We're going to use GimpApplicator's output crop for more than just
split previews. Rename gimp_applicator_set_preview() to
gimp_applicator_set_crop(), and add gimp_applicator_get_crop(),
which returns the output crop rectangle, or NULL if cropping is
disabled.

In GimpFilterTool, show the region combo when applying a non-point
op, as well as when applying a position-dependent point op. The
result of non-point ops may depend on the choice of input region,
even if the op is not position-dependent.
(cherry picked from commit 7949fd9a28)
In gimp_drawable_apply_operation(), use a temporary
GimpDrawableFilter to apply the operation, instead of using a
shadow buffer. This renders and composits the op directly into the
drawable buffer, avoiding an intermediate buffer, requiring less
space and speeding up processing.
(cherry picked from commit b201f73562)
Remove the use_split_preview and use_result_cache parameters of
gimp_applicator_new(), and allow enabling/disabling the cache
(through gimp_applicator_set_cache()) and the preview crop (through
gimp_applicator_set_preview()) after construction.
Move the preview crop node after the result cache, and remove the
separate preview cache node. This eliminates an extra cache
buffer, reducing the space consumed by filters, and speeds up split
preview, since the cached result now includes the output
compositing.

In gimp_drawable_merge_filter(), align the region copied to the
undo buffer to the drawable buffer's tile grid, so that the copied
tiles are COWed.
(cherry picked from commit cba4bc4781)
We now perform the conversion of filter output to the drawable
format as part of the individual filter nodes (see the last few
commits), so there's no need for another conversion after the
filter stack.
This reverts commit d6e0ca5054.
(cherry picked from commit 95393722cc)
Set the output format of floating-selection applicators to the
target drawable format. We're going to remove the global
GipDrawable convert-format node, which we use to get correct
previews for indexed drawables, so that each filter now has to do
its own format conversion.
(cherry picked from commit 0560c5a6fe)
In GimpDrawableFilter, set the applicator's output format to the
drawable format, so that the cache uses the drawable format, and so
copying the cached result to the drawble's buffer when comitting
the filter becomes much cheaper, and, in particular, doesn't
require reading tiles out of the swap. This notably improves
commit speed in large images, at the expense of requiring a few
extra conversions during preview.
(cherry picked from commit 8e57ee2265)
In GimpApplicator, add gimp_applicator_set_output_format(), which
can be used to explicitly set the format of the result. In
particular, this allows controlling the output cache format, which
can speed up the merging of cached filters.
(cherry picked from commit b93df0311f)
In GimpLineArt, use the "invalidate-preview" signal of the input
viewable, instead of its "painted" or "rendered" signals, for
asynchronously computing the line art. Subsequently, remove the
aforementioned signals from GimpDrawable and GimpProjection,
respectively. This simplifies the code, and reduces the number of
signals.
(cherry picked from commit ef9b1f6694)
This commit completely removes the "Edit -> Fade..." feature,
because...
- The main reason is that "fade" requires us to keep two buffers,
instead of one, for each fadeable undo step, doubling (or worse,
since the extra buffer might have higher precision than the
drawable) the space consumed by these steps. This has notable
impact when editing large images. This overhead is incurred even
when not actually using "fade", and since it seems to be very
rarely used, this is too wasteful.
- "Fade" is broken in 2.10: when comitting a filter, we copy the
cached parts of the result into the apply buffer. However, the
result cache sits after the mode node, while the apply buffer
should contain the result of the filter *before* the mode node,
which can lead to wrong results in the general case.
- The same behavior can be trivially achieved "manually", by
duplicating the layer, editing the duplicate, and changing its
opacity/mode.
- If we really want this feature, now that most filters are GEGL
ops, it makes more sense to just add opacity/mode options to the
filter tool, instead of having this be a separate step.

... 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!).

Improve the speed of gimp_gradient_get_color_at(), which is used by
gimp:gradient during processing when the gradient cache is too big,
by disabling type checking, and inlining and avoiding some function
calls.
(cherry picked from commit 93f4b18704)
Practically it means that the algorithm won't close line art anymore
with both settings at 0. This can nevertheless still be a very useful
tool when you have a drawing style with well-closed lines. In such a
case, you will still profit from the color flooding under the line art
part of the algorithm.
Moreover with such well-closed zones from start, you don't get the
over-segmentation anymore and the threaded processing will be faster
obviously.

Zlib is a "better" compression in the meaning that it is a more advanced
and complex algorithm than RLE. And in most cases, it should end up in
smaller file sizes. But as any algorithm, there may be cases when the
expectations are not met (worst cases or such). That's the nature of the
maths. Still we should not make the checkbox text over-complicated (it
is not the place to teach algorithmic), yet we can at least add a small
tooltip text.
(cherry picked from commit c3ac722995)
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.

After discussing with Mitch, it turn out commit 717c183a3e was fixing
(or rather working around) actual issues of broken device/usb stack
issues on Linux, as expected.
Nevertheless on Windows, this broke in turn many tablets (see commit
ce24e16083). Therefore we do a very ugly #ifdef to bail from duplicate
devices on Windows whereas we continue on Linux. This fix and difference
of behavior is completely empirical, rather than based on actual good
logics, so that's quite annoying, but well… not much choice here.
Also note that since we had no report of breakage on other OSes (such as
macOS/BSD), at least that I know of, I let them with the Linux code
path.

Currently in bucket fill tool, the modifier was only switching fg to bg
and bg to fg, and was doing nothing when pattern was set. I make it
switch to fg as well (and remember which was the original value).
