Centralized method to obtain ScrArea names. Areas can add an optional
space_name_get callback to provide a name that differs by subtype. If
not defined then ED_area_name will return RNA UI name, which is correct
in cases without area subtypes. This eliminates the current use of
RNA_property_enum_name_gettexted using a temporary context, which
results in the reported (hard to duplicate) error.

The swapping code incorrectly expected the link to have a start and end.
However, this was not necessarily the case when attempting to create
a link from a node to itself. This case has special handling in
`node_link_find_socket`.
This adds support for attaching gizmos for input values. The goal is to make it
easier for users to set input values intuitively in the 3D viewport.
We went through multiple different possible designs until we settled on the one
implemented here. We picked it for it's flexibility and ease of use when using
geometry node assets. The core principle in the design is that **gizmos are
attached to existing input values instead of being the input value themselves**.
This actually fits the existing concept of gizmos in Blender well, but may be a
bit unintutitive in a node setup at first. The attachment is done using links in
the node editor.
The most basic usage of the node is to link a Value node to the new Linear Gizmo
node. This attaches the gizmo to the input value and allows you to change it
from the 3D view. The attachment is indicated by the gizmo icon in the sockets
which are controlled by a gizmo as well as the back-link (notice the double
link) when the gizmo is active.
The core principle makes it straight forward to control the same node setup from
the 3D view with gizmos, or by manually changing input values, or by driving the
input values procedurally.
If the input value is controlled indirectly by other inputs, it's often possible
to **automatically propagate** the gizmo to the actual input.
Backpropagation does not work for all nodes, although more nodes can be
supported over time.
This patch adds the first three gizmo nodes which cover common use cases:
* **Linear Gizmo**: Creates a gizmo that controls a float or integer value using
a linear movement of e.g. an arrow in the 3D viewport.
* **Dial Gizmo**: Creates a circular gizmo in the 3D viewport that can be
rotated to change the attached angle input.
* **Transform Gizmo**: Creates a simple gizmo for location, rotation and scale.
In the future, more built-in gizmos and potentially the ability for custom
gizmos could be added.
All gizmo nodes have a **Transform** geometry output. Using it is optional but
it is recommended when the gizmo is used to control inputs that affect a
geometry. When it is used, Blender will automatically transform the gizmos
together with the geometry that they control. To achieve this, the output should
be merged with the generated geometry using the *Join Geometry* node. The data
contained in *Transform* output is not visible geometry, but just internal
information that helps Blender to give a better user experience when using
gizmos.
The gizmo nodes have a multi-input socket. This allows **controlling multiple
values** with the same gizmo.
Only a small set of **gizmo shapes** is supported initially. It might be
extended in the future but one goal is to give the gizmos used by different node
group assets a familiar look and feel. A similar constraint exists for
**colors**. Currently, one can choose from a fixed set of colors which can be
modified in the theme settings.
The set of **visible gizmos** is determined by a multiple factors because it's
not really feasible to show all possible gizmos at all times. To see any of the
geometry nodes gizmos, the "Active Modifier" option has to be enabled in the
"Viewport Gizmos" popover. Then all gizmos are drawn for which at least one of
the following is true:
* The gizmo controls an input of the active modifier of the active object.
* The gizmo controls a value in a selected node in an open node editor.
* The gizmo controls a pinned value in an open node editor. Pinning works by
clicking the gizmo icon next to the value.

This adds a new `name` member to the `GeometrySet` class. This name can be set
with the new `Set Geometry Name` node. Currently, the name is only used in the
spreadsheet when displaying instances.
The main purpose of this name is to help debugging in instance trees. However, in the
future it may also be used when exporting instance trees or when creating separate
objects from them.
Note, the name is not expected to be unique, it is fully in user control.
Naming geometries is necessary to make the spreadsheet more useful for instances,
because currently the user has no information for which geometry is used by each instance.
We also want to use this name to improve the integration with grease pencil where
sometimes layers become instances with the same name.

Also see 06be295946.
These aren't all cases, but a few that I found by addding a static
assert in `MEM_new` so that it fails for trivially constructible types.
This change allows to pass optional freeing and copy callbacks to
functions setting the `func_argN` member of the `uiBut` and `uiBlock`
structs. These callbacks are used to free or duplicate the data stored
in these void pointers.
Defaults are set respectively to `MEM_freeN` and `MEM_dupallocN`, to
match previous hard-coded behavior.
Utils template functions are added to easily generate callbacks to
types that are managed with the `MEM_new`/`MEM_delete` C++-style
allocation, as long as they provide a copy constructor.
Note that this change should be considered as a temporary, transitional
solution. A more robust and future-proof solution is to move towards
more usage of `std::function` for these callbacks, which can then own
and manage their custom data themselves.
NOTE: Had to make `NodeLinkItem` trivial again, by removing its default
values and instead using an 'init' function. Please ensure that the
code area you are using your data with _is_ compatible with c++ memory
handling. UI code generally is not currently.
Calling `MEM_freeN` on data allocated with `MEM_new` is bad, since it
will not call a destructor matching the one invoked as part of
`MEM_new`.
While in practice cases fixed below were 'not a problem' currently, as
they are trivial Cpp types (and therefore their destructor is doing
nothing), `MEM_freeN` has no way to ensure it is dealing with such a
trivial data type, so allowing such mismatch is dirty and dangerous.
Note that almost all fixed cases look more like unintentional mistakes
(mis-usages of `MEM_new` instead of `MEM_cnew`).
NOTE: There is one more (known!) case in the asset code, which fix is
slightly less trivial, and will go through a separate PR.
NOTE: This is a by-product of some work to detect such invalid usages of
`MEM_freeN` on memory chunks allocated with `MEM_new`.

Basically this tries to make the API to stop and kill jobs more explicit &
consistent, so intent is expressed clearly & behavior as expected.
- Remove use of the job start callback address as identifier for the job.
6887dea786 already removed this pattern from the jobs system internals, this
commit also removes it from the API.
- Make stop & kill API and implementation consistent. E.g. don't stop/kill jobs
by either owner **or** type/callback in one function, and by owner (if
provided) **and** type/callback in another. Causes some small behavior
changes, documented inline.
- Use the same job type and API for all preview render jobs (change by Brecht).
There doesn't seem to be a need for the separated types, in fact the
separation might have caused some issues earlier (and added code complexity).
- Add/improve function documentation.
This does actually have subtle behavior changes that are known, see PR, but
they were investigated carefully and seem like implementing wanted behavior.

Now the `uiBlock` array for node is indexed with `node.index()` instead
of the draw-index which is not as readily available in some cases.
The main alternative would be to create an extra map from node index
to draw-index but that doesn't seem worth it right now.
The fix is to support interleaving the drawing of zones and frames.
The draw order is determined by the width of the zones/frames.
Larger areas are drawn before smaller ones. This makes sure that
everything is as visible as possible.
The zone border outlines are still drawn on top of all frames.
Solving that is technically more challenging, because we don't want
to use transparency for zone backgrounds because that results in
many possible mixed colors which we want to avoid. Fortunately,
drawing the outlines on top seems to be quite useful anyway.
The hidden socket in the Viewer is not shown when a new link to it is created.
This is because the hidden property of the socket is not updated when a new
link to it is created.
Fixing it by simply manually update the property after a new link is created.

Masks are not updated when edited when using the GPU compositor. That's
because the GPU compositor caches static resources and invalidates them
according to the recalculate flags that the depsgraph flushes to IDs.
The issue is that the flags are not flushed to the evaluated IDs of the
compositor depsgraph, but rather to some other evaluated versions of the
IDs.
To fix this, we make the compositor depsgraph persistent and store it in
the scene runtime. This allows us to reliably track changes to resources
used by the compositor and also reduces the overhead of depsgraph
creation in the compositor job.
Patch originally provided by Sergey.
Fixes#121188.

This patch removes the Auto Render option from the compositor. This is
done for the following reason:
- The option didn't really work except in the case of transforming an
object. So it wasn't really reliable.
- It made little sense to use since the introduction of the Viewport
Compositor.
- It had a number of UX issues, including the fact that it can't be used
with animation playback, and the fact that rendering can get in the
way of the UI depending on the preferences for temporary editors.

- "Show the result of running commands in the main interface...": add
punctuation.
- "Re-Installed" -> "Reinstalled" seems more common.
- "increase_" and "decrease_subdivision" in the Grease Pencil
modal...: use title case instead of snake case for label.
- "Use a automatic number..." -> "an", typo.
- "... points,{} splines": missing space.
- "End Frame is larger than Start Frame": wrong order in error message.
- "Approximate the object as sphere, which diameter is equal to
thickness the defined...": grammar.
- "Show Seconds" -> "Use Timecode": this option is not necessarily about
seconds. Suggested by Pablo Vasquez.
- Brightness and contrast node input descriptions: add missing spaces.
- "Gamma controls the relative intensity... full white.": remove
trailing ".".

It seems that when ensure_nodetree_previews calls duplicate_material,
ntreeLocalize removes the muted node from the copy of the nodetree,
so later in ensure_nodetree_previews nodeFindNodebyName can't find it
and therefore parent is NULL.
With this change, the muted node just doesn't get its preview updated.

Add an overlay option to automatically display a label on reroute nodes.
This automatic label is propagated through chained reroute nodes and
is based on the explicit label of linked reroute nodes.
