Inspired by Mark Sweeney's work.
This patch allows the four buttons on the
sides of the canvas (Zoom, Quick Mask,
Image Menu, and Navigation Image)
to resize based on the user's icon size
preferences.
layer_mask points to the original mask created by xcf_load_layer_mask. We copy
this pointer into channel, and xcf_load_channel_props can overwrite this
pointer and free the original mask. If this happens, layer_mask points to
the now-freed original mask, and should not be used.
Therefore we need to change later parts of xcf_load_layer_mask to use channel
instead of layer_mask. Additionally, we add a block and move layer_mask into
this block to guarantee that layer_mask cannot be used after it has
potentially been freed.

Follow GIMP's code style regarding variables, comment style and

Currently if your image history includes an
image with a long name, the Welcome
Dialog will stretch out to match its width.
If the color profile name is long, then the
color scales will also stretch out due to
the profile label.
This patch adds ellipses to the Welcome
Dialog and a scrollwindow to the
ColorScales to prevent this.
Ported from ca5688bf6d
Just to note, we are already not using Assembly code
in 10bit and 12bit libraries. So, no feature dropped.
---
Also, little fixes to some dev docs regarding Clang.
Unlike GIMP, Photoshop does not support indexed images with
multiple layers. We have been silently merging layers down when
exporting to PSD, but this may be confusing to users.
This patch adds a label that notifies the user if they export an
indexed image with more than one layer.
...based on icon size preferences.
Inspired by Mark Sweeney's work.
Since the icon size is based on a formula,
the CSS value determines the maximum
size rather than being used directly.
Needs backport to 2.10
gimp_dock_windows_constructed creates a GimpDockColumns, a child widget,
and keeps a private reference to it at dock_window->p->dock_columns.
Then it connects the signal dock_columns.doc_removed to two callbacks:
gimp_dock_window_dock_removed() and gimp_dock_window_update_title().
gimp_dock_window_dock_removed() callback is called first and can
destroy the GimpDockWindow widget and its child widget GimpDockColumns.
Then gimp_dock_window_update_title is called
and tries to call dock_window->p->dock_columns.get_docks()
but it is already destroyed.
The fix is to nullify the internal pointer to dock_columns when destroyed,
and encapsulate access to dock_columns.get_docks so that it
returns a valid but empty list when dock_columns has already been destroyed.
Alternatively, you might be able to fix it by rearranging the order
of connections to dock-removed signal, but then the title would be wrong.
Another alternative might be to rethink the whole destruction sequence.
The ARTIFACTS_SUFFIX is being dropped on building scripts because:
1) This will make possible to further simplify Installer scripts in other commit
2) There is no script that uses multi-arch _build/_install at same time on CI
However, there are two use cases: to build Debian and flatpak; and, on Win,
to build on CLANGARM64 and CLANG64 (?). But probably they are pretty niche.
I suppose that people who build on Debian (or other dev-oriented distro)
willn't want to mantain deps in two sys prefixes (pkg and GNOME runtime)
+ two gimp prefixes (out of sandbox and sandbox) due to huge storage use.
Why someone would want to build with emulation on Win ARM64 I don't know.
Anyway, people that know how to do this stuff probably can change the .sh.
3) When building locally, the contributor doesn't need to know the arch at all.
Indeed, without this suffix, the scripts are inline with gimp-web-devel and
prevent some first-sight confusion when reading them that I've seen on IRC.
4) These arch suffixes can be understood as '_install-*' being distributable
which is not true. So, without this suffix we could make more clear
what is a package (when GitLab fix the glob bug in 'expose_as' someday).
---
Despite .gitlab-ci.yml not being a script, it needed to be touched too
because cross scripts depends on Debian jobs due to gimp-data MR.
If a given layer's properties contain multiple PROP_ACTIVE_LAYER entries, we
could add multiple entries for the same layer in info->selected_layers.
However, xcf_load_layer_props and xcf_load_layer both contain logic that
overwrites the layer pointer - they do take care of updating
info->selected_layers and and info->floating_sel (both of which could contain
or point to the current layer). Crucially, they both assume that
info->selected_layers can only contain this layer once - hence they only
remove it from the list once. This logic also frees the old layer because it
thinks that it's no longer in use.
But if we've added the original layer to selected_layers multiple times,
and then use the logic that overwrites layer, selected_layers will still
contain an invalid pointer to the now-freed original layer. Any later
code that tries to read info->selected_layers will hit a user-after-free.
Therefore we need to check if the current layer is already in the
selected_layers list, and avoid adding it again if it's already there.
(It also seems illogical to say that a layer is selected twice, but I'm
focusing on the code-correctness aspect in my analysis.)
Adjustment by Jacob Boerema: the correct way to test that a value does
not exist in a list is to check for the value being negative. Also add
a message to warn users.

Inspired by Mark Sweeney's work.
GimpToolPresetEditor has an icon next to its title which does
not react to icon size changes.
GimpToolPresetEditor's parent_instance, GimpEditor, already
has a "button-icon-size" CSS style which can be accessed in
its children. This patch adds signals to listen for icon size
changes and update the icon size accordingly.
Resolves#9105
The XCF compression setting is initially
set to FALSE. It was only updated from the
Save Dialog, so if the user exports then
compression is reset if they save the XCF
again.
This patch adds a condition on export
where we get the image's compression
setting, instead of always defaulting to
FALSE. This allows you to save and export
the same image without having to
re-enable the compression setting each
time.
A follow-up to the previous commits, that address the tga issues from
issue #11822.
On Windows, when using the error console for messages, a huge amount
of error messages, that can be generated with special fuzzed images,
like crash-f65fd5404bff32c1d9d10ee049d9c98d02bbbdc2.tga from
the above mentioned issue, can cause GIMP to crash.
Although this is most likely caused in the error console or its
dependencies, we should not let it cause problems here until that is
fixed. There is also no real need to generate a huge amount of similar
repeated error messages, so let's limit it to 10 per read line of input.
We are trying to copy all bytes in the current row, which is the width times
the number of bytes per pixel (stored in info->bytes), not width times bits
per pixel.
Copying too much data allows certain inputs to induce a heap-buffer-buffer
overflow read, and probably also a write, see ASAN output below:

A malformed colourmapped tga file could specify color IDs that are not
contained in the colourmap. Therefore we add some bounds checking to
ensure that we only use entries that actually exist.
We could completely give up on such files, but it's just as easy to fall
back to the first colour in the map in this case. However we can only
fall back to the first colour in the map IF the colourmap contains
at least one entry. Therefore we add an up-front check to verify that
colourmapped images actually do contain at least one entry.
Without this bounds-checking, it's possible to induce a heap-buffer-overflow
read in apply-colormap(), see ASAN output below:

If the colourmap contains more than 256 items AND has alpha, it should always
be promoted to RGBA. Therefore we move the "if (info->alphaBits)" check into
the first if clause, to avoid accidentally demoting to RGB in this scenario.
Other parts of the tga parser assume that the destination array is RGBA
when alphaBits is not zero. For example, upsample() will always write 4 bytes
per pixel when alpha is set - (even if we only allocated 3 because we thought
we should use RGB). Erronously allocating only 3 bytes makes it easy to induce
a heap-buffer-overflow write, see ASAN output below. (apply_colormap makes the
same assumption and would probably do the same thing, but upsample is the
first location that we'd hit this issue.)

We allow passing NULL gvalue for an empty GimpObjectArray, for convenience.
For example to plugin sel2path which doesn't use drawables.
But crossing the wire, create an empty GimpObjectArray
having an arbitrary type for elements.
Note that the widgets are still made
with GTK directly. The primary goal of this
initial port is to remove the last usage of
gimp_export_dialog_new (). Future work
will be needed as currently we can not
automatically generate widgets from
array parameters.
The visibility lock icon and help ID was accidentally
left off the PathsTreeView set-up.
The Path Attributes also used the wrong icon to indicate
the paths were locked (compared to the one shown in the
Path Attributes dialogue).
Revise the tests that can't default the args.
Actual args default to the min value formal declared in the PDB.
The declared min value must correspond with declaration in GEGL.
As of fcdddad2, the requirement for layers
to be attached before NDE filters can be
applied has been removed on app/core.
This patch removes the restriction from
the PDB call for filters as well.
* file-sunras, sparkle, and fractal-explorer
were converted to use GimpChoice with
the RadioFrame setting
* Unnecessary store variables were
removed from hot and file-psp
