In GimpChunkIterator, avoid preparing the current rect before
merging it back to the iterator's region, to save some work.
Additionally, strengthen the iterator's invariants and simplify
code.

In GimpViewable, don't invalidate the preview when thawed, unless
there was an explicit call to gimp_viewable_invalidate_preview()
while it was frozen. This avoids invalidating the previews of an
invisible drawable's ancestors when the drawable's preview is
frozen/thawed.
(cherry picked from commit 9dabad4cb9)
When freezing/thawing a top-level drawable's preview, only freeze/
thaw the image preview if the drawable is attached.
(cherry picked from commit de36e33347)
Add GimpViewable::preview_{freeze,thaw}() virtual functions, which
get called when the viewable's preview is frozen/thawed. Implement
the functions in GimpDrawable, recursively freezing the parent
drawable's preview (or the image's preview, for top-level
drawables) while the drawable's preview is frozen. For layer
masks, freeze the associated layer's parent.
This avoids updating layer-group/image previews while painting on,
or applying a filter to, a descendant layer. This both reduces
lag, and fixes a discrepancy between the layer's preview, which
isn't updated, and its parents' previews.

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).

Include the system-wide gtkrc file, in addition to the user-
specific gtkrc file, in the generated themerc file, instead of
copying the former into the latter when creating the user's
gimpdir. This allows us to modify the system-wide gtkrc file, and
having the changes take effect in existing installations.
In gimp_drawable_edit_fill(), when performing a non-direct fill,
use a GimpDrawableFilter with gimp:fill-source, added in the
previous commit, instead of using gimp_drawable_apply_buffer() with
an intermediate fill buffer. This avoids allocating a full-size
fill buffer, which may occupy a lot of space in pattern fills.
(cherry picked from commit 234f76b6fb)
In gimp_drawable_fill_buffer(), when the fill-source is a pattern,
avoid going through an intermediate buffer when there's no profile
transform, and use the destination-buffer format for the
intermediate buffer, instead of the pattern format, when there is a
profile transform.
(cherry picked from commit 3c1634ee0d)
Add gimp_fill_options_get_format(), which returns the format to be
used for the fill buffer; this is the same format used during
compositing. Use this format in gimp_fill_options_create_buffer(),
instead of the drawable format.
This fixes the result of fill operations when the fill color/
pattern is not representable in the drawable format, and speeds up
color fills by avoiding color-conversion for the fill buffer during
processing.

In GimpDrawableFilter, use
gimp_gegl_node_set_underlying_operation() to the the input
operation node as the underlying operation of the filter node.

In gimp_drawable_real_apply_buffer(), use GimpChunkIterator to blit
the applicator's output to the drawable's buffer in chunks, to
minimize the space used for intermediate results.
(cherry picked from commit 8f845d3a51)
In GimpChunkIterator, redajust the target area at each step,
instead of at each iteration, to adapt more quickly to the current
processing speed. To avoid creating uneven chunks as a result,
only change the chunk height at the beginning of rows, unless the
resulting area would be more than twice as big as the target area.
(cherry picked from commit e904b71242)
In GimpProjection, store the priority rect in image coordinates,
and only convert it to projectable coordinates when initializing
the chunk-iterator's priority rect. This allows us to preserve the
priority rect across projectable structure/bounds changes.
(cherry picked from commit 9d80ccc3e6)
In gimp_drawable_merge_filter(), don't disable the filter
applicator's output-format conversion node if the output format is
different than the drawable's format, since it may change the
result.
(cherry picked from commit 30da2f3d6f)
In gimp_drawable_merge_filter(), disable the filter applicator's
cache and output-format conversion nodes before processing the
uncached region of the filter, so that the result is written
directly to the drawable's buffer.

... immediately after an image precision change
When flushing a projection, make sure it has a buffer, instead of
bailing if it doesn't. We rely on the image projection's "update"
signal to update the display after certain operations that free the
buffer, which would previously fail to happen, and cause subsequent
flushes to be ignored until the buffer is explicitly accessed.
This fixes commit b07f810273.
(cherry picked from commit 106df3b794)
In gimp_group_layer_get_size(), make sure to always set *width and
*height, even when the group is empty, so that when the function is
called through gimp_projectable_get_size() by the group's
projection, the correct size is reported. This makes sure we
update the correct area when the group becomes empty.

In gimpchannel-select, move some of the common functionality of the
various gimp_channel_select_foo() functions to gimpchannel-combine.
Furthermore, don't special-case CHANNEL_OP_INTERSECT, but rather
pass it over to gimpchannel-combine, which is now prepared to
handle it in all functions, as per the previous commits.
In gimpchannel-combine, factor out the common functionality of the
various gimp_channel_combine_foo() functions into a pair of
gimp_channel_combine_{start,end}() functions, which are called
before/after the actual gimp_gegl_mask_combine_foo() function,
respectively. In particular, these functions deal with calculating
the new channel bounds. Previously, the various
gimp_gegl_mask_combine_foo() functions would implicitly invalidate
the channel bounds (since commit
d0ae244fe8), rendering the bounds-
recalculation code ineffective. This avoids manually recalculating
the bounds in many cases, speeding up selection operations.
(cherry picked from commit 8e77347cac)
Improve gimp_gegl_mask_combine_ellipse_rect() -- the funciton
responsible for rendering ellipse/rounded-rectangle selections.
Most notably, this commit significantly improves the function's
performance, by identifying whole tiles, whole rows, or parts of a
row, that are fully inside, or fully outside, the ellipse, and
filling them in bulk, instead of calculating the anti-aliasing
value at each pixel, which is now only done along the
circumference.
This commit also improves anti-aliasing, by more accurately
approximating the distance from a pixel to the ellipse, and by
normalizing the distance according to the pixel's cross-section
length in the direction of the said point. In particular, we
guarantee that pixels that are fully inside/outside the ellipse
have a value of 1/0, respectively, facilitating the aforementioned
optimization.
Additionally, this commit fixes various edge cases where several
primitives coincide at a single pixel (in the rounded-rectangle
case), adds support for CHANNEL_OP_INTERSECT, and parallelizes
processing.

Do not take "Sample merge" into account when picking colors in a
single-layer image. The reason is to be able to get the index
information on indexed image. This information is lost otherwise when
using the whole image as a pickable.
Of course, other exceptions are possible, when you'd pick exactly a
colormap color, but I don't think it's worth making the code
extra-complicated for these. My previous commit will anyway already
select the right color in the colormap on common cases. Though it will
still fail to select the right index when several indexes store the same
color, on a multi-layer image, if you check "Sample merged" while the
right index was not the first one amongst the duplicates.
(cherry picked from commit 31b2b55b28)
The colormap saves colors as unsigned char, which can be very inaccurate
compared to high precision colors. When adding colors from GimpRGB into
the colormap, use the original value to fill the colormap palette
instead of making a round trip conversion from double to uchar, then
back to double.
This also fixes a direct bug I encountered when adding the current
foreground color in the image colormap. Yet the GimpFgBgEditor or the
GimpColorHistory would still show the color out-of-gamut in cases when
the returned RGB after the roundtrip was not close enough to the
original RGB (even despite using an epsilon in GimpPalette code).

Line-art computation can take a long time, and it's therefore
desirable for it to be interruptable. While we do cancel the line-
art async when its result is no longer needed, most parts of the
computation don't respond to the cancelation request, leaving the
async operation running in the background, blocking subsequent
async operations.
Implement cancelation support of line-art computation, by passing
down the async object to the various functions, and periodically
checking for its cancelation at various points. When the async is
canceled, we quickly abort the operation.
Even though cancelation now happens relatively quickly, some parts
of the computation are still uninterruptable and may incur some
latency, so we avoid waiting for the async opration to be aborted
after cancelation, as we did before.

... which is equivalent to gimp_parallel_run_async_independent(),
except that it takes an additional "priority" parameter, which
specifies the task's priority, with 0 being the default priority,
and lower values indicating higher priority. Unlike
gimp_parallel_run_async_full(), the priority parameter doesn't
directly control the task's priority in a queue, but rather, we use
it to control the priority of the task's dedicated thread, on
supported platforms (previously, all independent async tasks would
run with low priority.)
Use low priority when loading fonts, which can take a long time, to
keep the existing behavior.

Remove gimp_item_tree_clear(), added in last commit, and move its
code to gimp_item_tree_dispose(). Likewise, in
gimp_image_dispose(), use g_object_run_dispose() on the image item-
trees, instead of gimp_item_tree_clear().
(cherry picked from commit b0de51b6bf)
Add gimp_item_tree_clear(), which removes all the items of a
GimpItemTree, and clear the layers/channels/vectors item trees in
gimp_image_dispose(), *before* finalizing the image, so that the
corresponding items' desctructors are called while the image is
still alive. In particular, this allows the destructors to safely
call gimp_item_is_attached(), which happens when the image has a
floating selection, since commit
8d4e5e0ff7.

In gimppickable-contiguous-region's pixel_difference() function,
which is used, among other things, by the select-by-color and
fuzzy-select tools, when selecting by LCh/HSV hue, treat a pair of
colors as inifinitely far apart if one of them has positive chroma/
saturation, and the other has chroma/saturation that's very close
to 0; conversely, treat a pair of colors as equal if both of them
have chroma/sautation that's close to 0.
As a result, when the seed color is saturated, gray pixels are
never selected, while when the seed color is desaturated, all, and
only, gray pixels are selected.
(cherry picked from commit 9886b69dac)
When clicking on a line art pixel, only this pixel gets colored, which
is fine for actual (original) line art pixels. But on generated ones
(closure pixels, which are internal only), you end up with a single
pixel colored while the whole surrounding area is empty. This feels like
a bug (even though it was not one technically) as you have no way to
guess you are clicking on a closure pixel.
Instead, when this happens, simulate clicks on all neighbour pixels,
hence potentially coloring all surrounding regions, which is most likely
what you wanted.

In gimp_pickable_contiguous_region_by_color(), add a small epsilon
to the threshold value, to allow for small errors due to the input
color and pickable pixel-colors being converted to the common
format through different paths.
While we *could* special-case threshold == 0 when the input color
comes from the same pickable, as is the case for the select-by-
color tool, and perform an exact comparison in the original format,
in the more general case the input color can come from an arbitrary
source, such as a plug-in.

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.

In gimp_drawable_filter_sync_affect(), don't mask-out the filter's
alpha component when the drawable doesn't have an alpha channel,
since this is no longer necessary -- we now explicitly convert the
output to the drawable format as part of the graph -- and it
prevents the gimp:mask-components node from becoming a NOP.
(cherry picked from commit af2c7d1b33)
In gimp_drawable_get_active_mask(), when the drawable doesn't have
an alpha channel, set or clear the mask's alpha bit, according to
the state of the other bits, so that it never gets in the way of a
fully set/clear mask. The value of the alpha bit doesn't matter
when there's no alpha channel, however, having a uniform mask
allows us to skip component masking altogether.
Additionally, provide a default implementation for
GimpDrawable::get_active_mask() which returns a full mask, and
remove the equivalent implementation for GimpChannel.

Remove gimp_drawable_replace_buffer(), which is no longer used
anywhere since commits ddb69b77a7 and

redundancy, since all compositing is now done through the layer-
mode code.
Furthermore, gimp_drawable_replace_buffer() used the drawable's
active-component array, whose layout depends on the image mode, as
an argument to gimp_gegl_replace(), which always expects an RGBA
component array, resulting in broken component masking in non-RGB
images.

The algorithm to compute a zone area by following its border only works

not be the case, but this is the safe case as it does not prevent
closure creation).
