When constructing a prop-GUI widget for an angle property with a
dial, use the the property's "direction" UI-meta, if exists, to set
the direction of the dial. Together with GEGL commit
7b0578073a0f20334b5a8a8fe57b649d9f302454, this fixes wrong dial
direction in certain ops that use clockwise angles.

... and rename "clockwise" to "clockwise-delta"
Add a boolean "clockwise-angles" property to GimpDial, which, when
set, causes the dial legs' angles to be measured clockwise, rather
than counter-clockwise. The property is FALSE by default.
Rename the "clockwise" property, which controls the direction of
the measured delta between the two angles, to "clockwise-delta", to
avoid confusion, and adapt the rest of the code.

... from layer context menu
In gimp_text_tool_set_layer(), do nothing if the input layer is the
currently-edited layer, otherwise we get a CRITICAL.

Second parameter of gimp_scanner_parse_token() and
gimp_scanner_parse_identifier() is not a return value. It is a value to
compare with.

This is a "for info" comment so that packagers don't forget them when we
sometimes depend on some specific GEGL dependencies.

In the dynamics editor, use the neutral curve color, which depends
on the current theme, for the "fade" curve, instead of hard-coding
it to dark gray, which is hardly visible with dark themes.

... depending on UI language
Use gimp_register_file_handler_priority(), added in the previous
commit, to increase the priority of the merged PSD loader, so that
the non-merged loader is always preferred over it (unless
explicitly chosen), regardless of the UI language.
(cherry picked from commit 0320126254)
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.

In GimpToolCompass (and, as a consequence, in the measure tool),
update the measured angle when the shell is scaled, rotated, or
flipped, so that we always satisfy the compass's constrains, and
render correctly.
(cherry picked from commit a810c6b60b)
When using a GimpToolCompass in 3-point mode, add a small gap after
the angle arc to the line corresponding to the "second" non-origin
point, so that it's visually distinguishable from the line
corresponding to the "first" point. This has significance for the
measure tool, since it determines the direction of the rotation
when straightening the image (the first point is rotated toward the
second point.)
(cherry picked from commit 0f03f9e9f5)
... does not restore the measure points
Halt the measure tool after straightening, thus removing the
expectation that undoing the operation should restore the original
points.
Halting the tool, rather than making undo work "as expected",
sidesteps several issues:
- Implementing undo correctly is tricky, since image-undo and
tool-undo are handled separately.
- In fact, the measure tool doesn't provide tool-undo, so that
image edits can be undone while the tool is active without
affecting the tool, and it's not clear that we want to change
this behavior. However, this makes undoing a straighten
operation a special case, and it's not entirely clear what the
behavior should be when undoing other kinds of transformations,
or when the measure points had changed since the straighten
operation.
- Perhaps most importantly, measure tool points are restricted to
the pixel grid, which means that when measuring an angle
against an orientation that's not fully horizontal or vertical
in image space (either using a 3-point angle, or when the
canvas is rotated), the resulting transformed point after
straightening doesn't generally land on the pixel grid, causing
it to be rounded, which can result in a non-zero angle after
the rotation. This is especially ugly, since clicking
"straighten" again at this point would cause another non-
trivial rotation.

Rename XCF property PROP_SAMPLE_POINT to PROP_OLD_SAMPLE_POINT and add
new PROP_SAMPLE_POINT.
The new property saves the sample point's pick mode plus some padding
for whatever else we might want to add. Always save the old property
too so nothing changes for older GIMP versions, and avoid loading the
old property if the new one was loaded before.
(cherry picked from commit 47a008be97)
Bind the "orientation" property of the measure-tool options to the
tool's compass widget's "orientation" property, instead of manually
synchronizing their values.
(cherry picked from commit 7a91aabf37)
Add an "orientation" option to the measure tool, corresponding to
the "orientation" property of GimpToolCompass (i.e., it controls
the orientation against which the angle is measured, when not in 3-
point mode.) The orientation is "auto" by default, so that the
angle is always <= 45 deg. Note that the "orientation" option
affects the tool's "straighten" function, so that the layer is
rotated toward the current orientation.
Use the "pixel-angle" and "unit-angle" properies of
GimpToolCompass to read the measured angle, instead of duplicating
the angle-measurement logic, in particular, so that we benefit from
the improvements/fixes of the previous commit.
(cherry picked from commit cb3b7a1ba5)
Add an "orientation" property to GimpToolCompass, which can be one
of "auto", "horizontal", or "vertical", and which controls the
orientation of the line against which the angle is measured, when
not in 3-point mode (previously, the line would always be
horizontal.) When "orientation" is "auto", the orientation is
automatically set to either horizontal or vertical, such that the
measured angle is <= 45 deg.
Keep the line horizontal, or vertical, in display-space, rather
than in image-space, so that the compass works correctly even when
the canvas is rotated and/or flipped.
Fix the compass's behavior when the image's horizontal and vertical
resolutions are different, both with and without dot-for-dot.
Add "pixel-angle" and "unit-angle" read-only properties, which
return the measured angle either with or without taking the image's
resolution into account, respectively. These properties will be
used by the measure tool in the next commit, instead of having it
implement its own angle calculation.
(cherry picked from commit d2f33cf1be)
Fix gimp_constrain_line() and friends to properly constrain line
angles when the image's horizontal and vertical resolutions are
different, and dot-for-dot is disabled.
(cherry picked from commit 4fefab1798)
Remember the sample point's GimpColorPickMode in the sample point
itself, so it is remembered across switching between images.
Not persistent in the XCF yet tho...
(cherry picked from commit a0129504c8)
This is just some preparation for fixing issue #1805, but actually
"target" is a much better name so I went the full way and also changed
GUI labels and the color picker tool options config property
accordingly.
If anyone notices at all, how horrible is it to lose your saved pick
target...

In gimp-parallel, always flush the async-operations queue (by
executing all remaining operations on the caller thread) when
setting the async-pool thread count to 0 (as happens when setting
GEGL_THREADS=1, per the previous commit,) and not only when
shutting GIMP down. Otherwise, pending asynchronous operations
can "get lost" when setting GEGL_THREADS to 1.
Additionally, in gimp_gegl_init(), initialize gimp-parallel before
before connecting to GimpGeglConfig's "notify::num-processors"
signal, so that the number of async threads is set *before*
GEGL_THREADS, in order to avoid setting GEGL_THREADS to 1 while
async operations are still executing.
Also, allow setting the number of gimp-parallel-distribute threads
while a gimp-parallel-distribute function is running (which can
happen if gimp-parallel-distribute is used in an async operation,
as is the case for histogram calculation), by waiting for the
parallel-distribute function to finish before setting the number of
threads.
(cherry picked from commit 432a884715)
When GEGL_THREADS=1, concurrent access to the same buffer is not
safe, which can result in errors if asynchronous operations are
allowed to run in parallel to the main thread (see
https://gitlab.gnome.org/GNOME/gimp/issues/1721#note_265898.)
Disable parallel execution of asynchronous operations when
GEGL_THREADS=1 for now, to fix this. Ultimately, GEGL should be
able to remain thread-safe even when GEGL_THREADS=1. Note that we
want to execute asynchronous operations on a separate thread even
when GEGL_THREADS=1, since the goal here is mainly to avoid
blocking the main thread during their execution, rather than
speeding their execution up (in particular, it's benecifical to run
asynchronous operations in parallel even on a single-core machine,
while parallelizing GEGL operations generally isn't.)
