gegl:focus-blur blurs the image around a focal point. It can be
used to create fake depth-of-field effects.
Add a prop-gui constructor which uses a FOCUS controller to control
the focus geometry.
(cherry picked from commit 60d4d25b93)
Add a new GimpToolFocus tool widget, which defines a focus region,
consisting of an inner limit, an outer limit, and a transition
midpoint between them. The widget allows controlling the limits
and the midpoint, and moving, scaling, and rotating the region.

... which constrains an angle to discrete increments in screen
space, similarly to gimp_display_shell_constrain_line().
(cherry picked from commit 8c1a277007)
Add a new GimpCanvasLimit canvas item, which draws an area limit
for different shapes. It will be used by the following commits to
implement GimpToolFocus.
(cherry picked from commit 06a2b4f338)
In GimpDrawTool, update the tool widget on GIMP_TOOL_ACTION_RESUME,
so that it can respond to changes in the display-shell scale/
offset. We'd previously done that for individual tools/widgets,
but let's just do it in one place.
(cherry picked from commit c73710e410)
In GimpDisplayShell, pause and restore the active tool when
rotating the canvas, similarly to scrolling and scaling.
(cherry picked from commit cd5e4e99dd)
There is no non-hackish way of fixing this without adding a new
"use-opacity-paint-mode" property to GimpToolPreset and a new toggle
in GimpToolPresetEditor. Restoring opacity and paint mode can now be
controlled explicitly, and defaults to TRUE.

If we don't do this, the clipboard owner doesn't get unreffed (also the
GtkClipboardClearFunc is not called either, but we don't set any so this
was not a big problem).
The main consequence was that copying was setting the Gimp object as an
owner, which kept a reference and prevent its finalize() method to run,
hence was leaking data (and in particular some GEGL buffers for
clipboard operations, which was how the issue became more visible upon
exit).
(cherry picked from commit fca6371e29)
Properly initialize GimpSelectionTool::saved_operation upon
modifer-key press, even when some modifiers are masked out by
GimpPolygonSelectTool while the tool is active. This avoids
erroneously "restoring" the operation to a previously-saved state
once the modifier keys are released.

Remove the "CMY" model from compose and decompose, it's gone from
babl. Also fix decomposing to CMYK by using the right component names.
(cherry picked from commit f3f8d3a54e)
Change while() to go from 0..360 instead of 0..361 so the code passes
automated tests. The code never ran into this situation but the change
is a small improvement anyway.

By only doing the snapping to white/black for whitest/blackest palette
entries when the original RGB data contained these colors we permit
choosing near white/black colors in the cases where this might be
a desirable result as the whitest/blackest colors.
(cherry picked from commit d4387987b5)
The median-cut algorithm to derive a suitable palette for the image
computes each index to be used as the average of colors in a 3d box
in a color space, making the result value drift away from the extremes.
This makes it nigh impossible to achieve pure white or black, even
when the original image contained these colors, like in scans of
printed documents and technical drawings.
We counteract the drift by snapping the whitest color to white and the
blackest color to black if the resulting colors of median-cut are
already sufficiently close to white or black.
(cherry picked from commit 9bb3ff42d7)
layers_opacity_cmd_callback(): get the select_type from
the GVariant instead of using the GVariant as an enum
directly (missed when porting, spotted by Massimo).
Fix the same bug in channels_select_cmd_callback()
and layers_mode_cmd_callback().

In GimpUnifiedTransfomTool, avoid moving the pivot when
readjusting, and when the transform directions are linked, if the
pivot is locked.
(cherry picked from commit d7c995153d)
... which copies a TransInfo array to the current info array,
possibly with modifications. While the default implementation
simply copies the array as-is, the following commit will override
the function for the Unified Transform tool, to avoid copying the
pivot position when the pivot is locked.
Use the function in GimpTransformGridTool, instead of copying the
array directly, as necessary.
