Fixes the error:
> Critical error: gimp_line_art_thaw: assertion 'line_art->priv->frozen'
This may happen in cases when we didn't actually freeze the line art at
pointer click, because we were in an invalid case (for instance,
clicking out of selection), hence we must not thaw the line art either
at button release.

In GimpProjection, when the projectable's size changes, while its
offset remains the same, simply update the projection buffer's
extent, instead of allocating a new buffer and copying the contents
over.
(cherry picked from commit 1577174739)
... which sets the extent of a buffer with an assigned
GimpTileHandlerValidate, clipping the dirty region to the new
extent.
(cherry picked from commit b4ee9ff055)
.... as a drop-in replacement for gegl_buffer_set_extent(), which,
in addition to setting the buffer's extent, clears any now-out-of-
bounds tiles, to free memory.

Something during the port to gimp-drawable-edit (commit
233ac80de1) broke add-bevel.scm when
the thickness is high enough for the selection to become empty.
Add an explicit check for a selection while constructing the bump-
map layer.

Change the tooltips of the "Image/Layer -> Transform -> Arbitrary
Rotation..." to make the two actions distinguishable in the action
search dialog, similarly to the other image/layer transform
actions.
(cherry picked from commit 9582cf7717)
Add a gimp-rotate-image-arbitrary action, and a corresponding
"Image -> Transform -> Arbitrary Rotation..." menu entry, which
activates the rotate tool in image mode (similarly to the
corresponding action for layers).
(cherry picked from commit 8bff415f59)
... so that the original transform-type of the rotate tool is
restored once the layer is rotated. Additionally, make sure to
set the tool's transform-type even if it's already active.
(cherry picked from commit 52ad37a2aa)
... which temporarily changes the transform-type of the tool,
restoring the original type once it's halted. To be used when
activating a transform tool through an action for a specific
transform type.
(cherry picked from commit f651db52fb)
Add a new "Image" transform type to the transform tools, in
addition to the existing "Layer", "Selection", and "Path" transform
types. The "Image" mode transforms the entire image, rather than a
single item. In tools with a preview, the preview shows the
transformed image projection. The clipping mode controls how the
canvas is clipped during the transform; in particular, the ADJUST
clipping mode resizes the canvas to fit its transformed size.

In GimpCanvasTransformPreview, use a GimpPickable, instead of a
GimpDrawable, as the preview source, so that we can use it with the
image projection, rather than just with drawables.
(cherry picked from commit 6023f97509)
... which controls whether or not the image is rendered by the
shell. We'll use this to hide the image while showing its
transform preview in the next commits.
(cherry picked from commit 539d666ae2)
Add a new gimp_image_transform() function, which transforms the
entire image, including all layers, channels (including selection
mask), vectors, guides, and sample points, according to a
transformation matrix. The canvas is resized according to the
clip_result parameter, the same way drawables are resized during
transformation; the layers are resized using ADJUST mode
regardless.
(cherry picked from commit c45f1b4148)
... which takes the symmetry axis as a parameter, instead of hard-
coding the axis to the middle of the image, and which additionally
takes the clipping mode as a parameter, controlling whether to clip
or resize the canvas. Note that the actual canvas size never
changes, but it may be offset when flipped around an off-center
axis, without clipping.
Implement gimp_image_flip() in terms of gimp_image_flip_full().
(cherry picked from commit ae080f06f9)
In the various PDB transform functions, avoid erroneously creating
a floating selection when transforming the image mask, and rather
transform the mask normally.
Remove the special clipping-mode handling for channels throughout
the transform (and drawable-filter) code, and rather use
gimp_item_get_clip(), added in the previous commit, instead. As
mentioned in the previous commit, we only modify the clipping mode
in top-level code, while having lower-level code use the clipping
mode as-is. This not only hides the actual clipping-mode logic
from the transform code, but, in particular, allows code performing
transformation internally to use arbitrary clipping modes.
Also, this commit fixes a bunch of PDB bugs all over the place :)
Add a new GimpItem::get_clip() virtual function, and a
corresponding gimp_item_get_clip() function, which return the
actual clipping mode to be used when transforming (or applying a
filter to) a given item, given the original clipping mode. This
applies only to whole-item transformations (i.e., when not creating
a floating selection), and should be used by the top-level code
applying the transformation, rather than by the actual
transformation code, so that the item can be transformed using a
different clipping mode internally.
Provide a default implementation that simply returns the input
clipping mode, and override for GimpChannel (to always return CLIP)
and for GimpVecotrs (to always return ADJUST).

In gimp_palette_mru_add(), if the added color doesn't match an
existing color, don't look for two duplicate existing colors (which
has quadratic complexity), since there shouldn't be any under
normal circumstances (as we're not adding duplicates to begin
with).
