Don't disable color-to-alpha for grayscale drawable, since the
operation is applicable to grayscale images (in particular, it
doesn't add color where there was none), and since we no longer
distinguish between layers and channels according to the drawable
format when updating the filters actions.
... (used to add one automatically)
In GimpFilterTool and gimp_drawable_apply_operation(), use
gimp_drawable_filter_set_add_alpha() to add an alpha channel when
applying an operation that specifies "needs-alpha" to a drawable
that can have alpha.
Don't disable gegl:color-to-alpha (which has "needs-alpha") when
the drawable doesn't have an alpha channel, if one can be added.
In GimpFilterTool, move all the drawable-filter option setup to a
new gimp_filter_tool_update_filter() function, and call it whenever
the drawable-filter's options need to be updated. This avoids
duplicating logic in various places.
Add a new GimpDrawable::supports_alpha() virtual function, and a
corresponding gimp_drawable_supports_alpha() function, which
determine if the drawable supports an alpha channel. The default
implementation returns FALSE, and GimpLayer overrides it to return
TRUE.
The crop-to-result and crop-with-aspect transform-boundary
algorithms seem to consistently fail in some cases, and spit out a
warning, which can be too verbose if it triggers the debug dialog.
Demote the warning to a g_printerr(), with an eye to just dropping
these algorithms altogether.

Add a "Synchronous preview" option to the transform-grid tools,
which renders the composited preview synchronously. This reduces
the lag for painting the preview, but can harm responsiveness for
bigger images, where rendering the preview is slow.
This is mostly an experimental option for now; it will become more
interesting once we have mipmap rendering.

In gimp_tile_handler_validate_validate_tile(), when validating a
partial tile with negative coordinates, make sure to adjust the
result of the modulo when calculating the tile-realtive coordinates
so that they're non-negative, to fix the tile-data pointer offset.
(cherry picked from commit d39822bcd7)
Add a "Composited preview" option to all transform-grid tools,
which displays the transform preview as part of the image
composition (i.e., as it would actually look when applying the
transformation, keeping the layer at the right position in the
stack, and with the right layer mode), instead of using an overlay.
This option is off by default, since it's generally slower to
render than an overlay, due to the lack of mipmap rendering. We're
also still using an overlay when transfoming a selection, and not a
whole layer.
In GimpTransformGridTool, when transforming a drawable, freeze the
drawable's preview while the tool is active, so that its ancestors'
previews don't get unnecessarily updated in response to hiding it.
In GimpDrawableFilter, add a
gimp_drawable_filter_set_override_constraints() function, which
allows bypassing certain constraints applied to the filter, based
on the drawable type and state.
Yes, this is a bit of a hack, added mostly as a quick-and-dirty way
to allow us to add filters to layer masks that affect their
bounding box, in preparation for composited transform previews.
Add an optional "format" parameter to gimp_drawable_merge_filter(),
which specifies the format to use for the output, possibly changing
the drawable's format.
In GimpDrawableFilter, add a gimp_drawable_filter_set_add_alpha()
function, which allows the filter to add an alpha channel to the
drawable when committed (by passing an appropriate format to
gimp_drawable_merge_filter()).
Change the default implementation of
GimpDrawable::get_bounding_box() to return the drawable source
node's bounding box, instead of the drawable's item bounds. This
allows filters to affect the size of all drawables, including, in
particular, layer masks.
Change GimpLayer's implementation of get_bounding_box() to return
the intersection of the layer's own bounding box, and the layer
mask's bounding box (if it has one), and update the layer's
bounding box when the mask is enabled/disabled, or when its
bounding box changes.
... by synchronously flushing the group's projection. This is
necessary for pass-through groups, since their projection is
normally flushed asynchronously.

In gimp:buffer-source-validate, invalidate the node in response to
GimpTileHandlerValidate::invalidated, added in the previous commit,
in addition to GeglBuffer::changed.
(cherry picked from commit bb8ee0e686)
Add a new GimpTileHandlerValidate::invalidated signal, which is
emitted when a region of the buffer is invalidated. This would
allow us to properly invalidate the graph in response; this
normally happens in response to GeglBuffer::changed, but this
signal is not emitted when a region is merely invalidated.
(cherry picked from commit 3ea391602e)
Add a "clip" property to GimpCanvasTransformPreview, specifying the
transform's clipping mode, and clip the preview accordingly.
In GimpTransformGridTool, sync the tool's clipping mode with the
preview's clipping mode.
(cherry picked from commit 7b2e6b7595)
Add a "Unified interaction" option to the 3D Transform tool, and a
corresponding "unified" property to GimpToolTransform3DGrid. When
active, all three interaction modes of the grid (camera, move, and
rotate) are available simultaneously, regardless of the active
dialog page. In this mode, the inner and outer regions of the item
are used for moving and rotation, respectively, and the vanishing-
point is controlled through through a handle.
(cherry picked from commit 30132fc2da)
In GimpToolTransform3DGrid, fix the test for determining which side
of the plane is facing the viewer, affecting the direction of
rotation when rotating around the local Z axis.

When ordering tools according to an existing toolrc file (which
is always present in a pre-existing profile), preserve the default
placement of newly-added tools, instead of always adding them to
the bottom of the list.

... brush does not have transparency
In the PAINT_MASK_TO_COMP_MASK paintcore-loops algorithm, used when
painting incrementally, multiply the paint mask values by the paint
opacity. Previously, the paint opacity was ignored, breaking
various dynamics affecting the opacity.
(cherry picked from commit 9fe33702fb)
Always enter relative adjustment mode when right-clicking an
unfocused compact GimpSpinScale, instead of showing the context
menu, since it otherwise leaves little room to enter relative mode
in narrow spin scales. The context menu can still be activated for
focused spin scales.
