Previously, the closure and bundle nodes were a bit restrictive when it comes to
socket shapes. Especially the bundle nodes did not support customizing the
socket shape at all, so they always worked with dynamic values. This was
problematic, because it meant that e.g. the outputs of the Separate Bundle node
looked like they couldn't be used as single values, and other similar issues.
With this patch, the following is supported (a few aspects were supported before
but now it all fits better together): * Support manually selecting socket shapes
in Combine Bundle, Separate Bundle, Closure Input, Closure Output and Evaluate
Closure nodes. * Automatic inferencing of shapes in all these nodes, as long as
the socket shape is set to "auto". * A new "Define Signature" option can be
enabled in the nodes. If enabled, linked nodes will also sync the socket shapes
from that node. In the future, we also want to add support for naming the
signature.

Currently cameras composition guide colors are defined in theme, and not even by an individual
property. They follow 3D Viewport -> View Overlay color, which also defines many other things,
such as world origin cursor. By default it's black and it's difficult to change, because then other
things stand out. But using default black for composition guides is impossible.
This PR, instead, adds new Composition Guide Color property on camera, and uses it in camera view.
This not only fixes the issue mentioned above, but also allows different cameras in one scene to
have different overlay colors. This is very handy when you have, for example, two cameras, one of
which looks at the black corner, and another at the lit-up white one. Using a single black or white color
in this case makes the other one more difficult to see. Now, each camera can have its own color.
This PR only changes color for Composition Guides, and NOT for Safe Areas and sensor. Reasons are:
- It's important to differentiate between different concepts, having everything one color is distracting
- Safe areas are per-scene and shared with Sequencer preview. The camera shouldn't dictate color there.
I have separate plans about handling safe areas in the future.

Currently, only the visibility of input sockets can be changed dynamically based
on other menu inputs. However, under some circumstances, it can also be useful
to hide certain outputs. For example, the built-in Curve Arc primitive node does
that.
This patch adds support for automatic detection of unused outputs. How to detect
unused outputs is less straight forward compared to inputs. This patch uses the
rule that an output is unused if it always outputs a "fallback value" (typically
0) irrespective of the currently used inputs. If the output is independent of
all inputs, it stays visible though.
There is a new small utility node called "Enable Output". It replaces a value
with it's fallback value unless it is disabled. This simplifies setting up
unused outputs. In theory, a normal switch node can also be used, but that is
less usable and the user will have to hardcode the fallback value for each type
which is not something that is explicitly exposed yet.
Supporting dynamic output visibility is also a prerequisite for exposing some
menu node options as sockets (e.g. in the Arc node).

Updates the `CurveMapping` `CURVE_PRESET_SMOOTH` curve to more closely
approximate the smoothstep function (y = 3x^2 - 2x^3). This has the
implication of changing what happens when the curve is reset, but does
not change any existing curves already stored in blendfiles.
Notably, this change primarily affects three operators:
* brush.curve_preset (Mesh Sculpting)
* brush.sculpt_curves_falloff_preset (Curves Sculpting)
* render.shutter_curve_preset (Motion Blur)

A subset of brushes behave as "anchored" brushes, in that they do not
apply to the surface continually underneath the cursor, but have a
starting point and then are influenced by the mouse movement. These
brushes behave oddly with tablet pressure sensitivity, as they cannot
modulate over the course of the stroke without causing odd behavior.
Currently, the pressure is only sampled at the very beginning of the
stroke, which makes it difficult to control intuitively. Further work
can be done to improve this behavior (e.g. D6603).
The full list of brush types affected is below:
* Grab
* Snake Hook
* Elastic Deform
* Pose
* Boundary
* Thumb
* Rotate
* Cloth with Grab deformation

When we directly call `exit()` from `sig_handle_blender_esc`, the
program will try to free up all static variables and terminate all
threads (and do some file handle cleanup).
The destuctor of the static sound `GlobalState` will hang if
`delayed_close_cv` is in use by other threads as it will wait for them
to let go of it before the destructor finishes.
To make sure that it can finish, the destructor now notifies all
potential threads that they should exit.

This PR adds an option "Affect Gizmo" for custom shape transforms to affect
the transform gizmos. If enabled, this will place the gizmo at the
location and orientation of the "Override Transform" (i.e. in its local space).
For Orientations: The gizmo mode *is* respected. I.e. global mode is aligned to the world etc.
There is a special case for "Gimbal" where it will not follow the orientation of the
"Override Transform" bone. I think it makes sense to keep it that way since this
is about the channels of the bone you are actually manipulating.
The other option is "Use as Pivot" with which the bone is actually rotated
around the override bone. This can be useful for rigs in which shapekeys and
armature deformation is combined

This adds support for packed linked data. This is a key part of an improved
asset workflow in Blender.
Packed IDs remain considered as linked data (i.e. they cannot be edited),
but they are stored in the current blendfile. This means that they:
* Are not lost in case the library data becomes unavailable.
* Are not changed in case the library data is updated.
These packed IDs are de-duplicated across blend-files, so e.g. if a shot
file and several of its dependencies all use the same util geometry node,
there will be a single copy of that geometry node in the shot file.
In case there are several versions of a same ID (e.g. linked at different
moments from a same library, which has been modified in-between), there
will be several packed IDs.
Name collisions are averted by storing these packed IDs into a new type of
'archive' libraries (and their namespaces). These libraries:
* Only contain packed IDs.
* Are owned and managed by their 'real' library data-block, called an
'archive parent'.

This patch adds a new Compositor modifier that applies a compositing
node group on a sequencer strip. This patch also introduces the concept
of a compositor node tree space subtype, where we now have a Scene and a
Sequencer subtypes. Practically, this just means that node like the
Render Layers node will not be available in the node editor in the
Sequencer subtype.
Future improvements includes:
- The compositor context is recreated on every modifier application,
while it should ideally be persistent somehow to make use of the
compositor static cache. This might require work from the compositor
side by moving the static cache outside of the context and make it
thread safe if needed. See `Render.compositor` for an example on
persistent context.
- GPU execution is not supported. This just needs a GPU context to be
bound before execution, but the tricky part is getting a GPU context.
See `render::Compositor::execute` for an example on bounding a GPU
context and why it is less straight forward.
- Node inputs are not exposed on the sequencer modifier interface. An
approach similar to Geometry Nodes modifier could be used, look at
`update_input_properties_from_node_tree` for reference, but notice
that Geometry Nodes naturally exempt the main Geometry socket because
Geometry inputs can't be exposed, but for the compositor, we will have
to exempt the main Color and Mask sockets manually. !145971

Previously it was only working for the single layer case. For multipart
we write the colorspace in each part. For single part we write the first
non-data colorspace, and hope data passes will be identified based on channel
name like Blender does (e.g. XYZ instead of RGB).
Reading is unchanged and still the same as before, in that it only reads the
colorspace from the first part. There is only one color space per image
datablock, so we can not store anything more currently. In practice it
would be unusual for all passes in a file not to either have the same
colorspace or be data.
All the compositor file output test images were updated to include the
metadata, so that the test will check if the metadata is there.

New "Interleave" option in image format settings, enabled by default in old
files and disabled by default in new files to write multi-part files.
By not storing all channels interleaved, it is possible for other applications
to load individual passes more efficiently. This might also work better with
compression.
We follow the OpenEXR docs in that the channel name is the full
Layer.Pass.Channel rather than just Channel. Some other renderers
(e.g. Houdini Karma) write just the channel and that is what our reading
code assumed so far.
I've verified that Nuke can read the multipart EXR files produced by Blender,
including multiview and cryptomatte.

In very old OpenEXR version there was a limit on the channel names, which meant
the pass names needed to be short like "DiffDir". Change them to be longer like
"Diffuse Direct".
* This breaks forward compatibility. Old Blender version will lose links when
reading compositing node setups with such passes, but #146571 will fix it
for 4.5 LTS.
* Add-ons, scripts and compositing setups in other applications that rely on these
names will also break.
* The find_by_type function for render passes has also been removed, as this was
already deprecated and replaced by find_by_name.
* We assume spaces in the name are ok, since we have passes with them already
and have not seen reports about compatibility issues.

the theme.

Currently there is a difference in the assigned accelerator keys for
Boolean attribute type for Store Named Attribute and Named Attribute.
For Named Attribute it is assigned <kbd>B</kbd> as a user would expect
but in the Store Named Attribute it is assigned <kbd>o</kbd> as it comes
after _Byte Color_ which leads to confusion when using lots of each node.
This PR changes the order of the socket types so simpler types come
first, and updates the attribute types to reflect this same ordering.
This fixes the issue with the accelerator keys and improves overall
consistency. The more specialised subtypes such as 8-Bit Integer, Byte
Color and 2D Vector all appear at the end of the menu in the same order.
This ordering will also be reflected in other nodes such as Sample Index,
Sample Curve etc.

Regression from 435b6743fd, when considering UI ID usages to define

Recent change 3a6a663a15 has some logic issues.
First, the grain size was clamped to be never lower than 256, which
doesn't make sense since the size of the array is never greater than
the number of threads. The numbers used in the division were also large
enough that multithreading wouldn't be used in many realistic cases
anyway. There's no need to cap the grain size at 1024, and also
`safe_divide` doesn't make sense in this scenario.

This function would only call `IDP_FreePropertyContent` on the items it
is releasing from its buffer, when reducing the length of the array.
However, it needs to call `IDP_ClearProperty` instead, otherwise some
invalid 'dirty' data is kept in the released properties, e.g. the `len`
value for groups or arrays.
Not sure how this never bit us before, but the recent asserts added by

released IDProps.

As discussed in the last geometry nodes workshop, the viewer node now
needs the flexibility to handle new features: bundles, closures, and
lists. This PR takes the opportunity to add support for an arbitrary
number of items. Values are displayed directly in the node are all
displayed in the spreadsheet, where a new tree view allows selecting
which data to view, including nested bundles. Lists, single values,
bundle items, and closure signatures are all visualized in the spreadsheet.
We also prioritize the existing viewer behavior that views a geometry
together with a field, so various special cases are added in the viewer
activation to handle this.
Bundle hierarchies are displayed in the new tree view in the spreadsheet
sidebar. The spreadsheet itself just displays bundle identifiers, types,
and the contained values. Design wise, there might be more integrated
ways to present that hierarchy, but doing it in the tree view is a very
simple starting place.
Interactively added viewer node inputs are now removed automatically
if the link is removed. There is a new "Auto Remove" flag for each input
controlling this behavior. It can't be enabled for all inputs all the time
because then one couldn't e.g. setup the viewer node properly using
a script (which might add a few inputs first and then creates links).
Also when viewer items are added with the plus icon in the sidebar,
they are not automatically removed immediately.

Previously the joining code put the final data into temporary mesh
data, which meant more complexity because it couldn't use the slightly
higher level APIs more commonly used for transferring data.
The process can be simplified by just merging into the active mesh
directly (though some care must be taken when that is used by
multiple selected objects).
This process avoids iterating over attribute data twice, by processing
values at the same time as copying them. Also some of the inner hot
loops are parallelized. There is more opportunity for trivial multi-
threading in the future.
Mismatched attribute types and domains will now choose the higher
complexity type and domain, which should help avoid information loss.
There was a bug with the existing face set processing which would
modify the source meshes. That is now fixed.
These are causing quite a big difference in existing files, which is not
easy to address in versioning. Since the goal of removing this was to
simplify things for us and that's not the case, just revert this change.
