Previously, menu sockets were always drawn as dropdown. This patch adds the
ability to draw them expanded instead.
As before, in the node editor, only the expanded menu is drawn, without the
label. There is simply not enough space for both. However, in the modifier and
operator settings the label is drawn currently. We'll probably need to add a
separate `Hide Label` option (similar to `Hide Value`) for group inputs that
support it. That would also help a lot with e.g. object sockets.

Like other runtime structs, it doesn't make sense to write this
data to files. And moving it out of DNA to an allocated C++ struct
means we can use other C++ features in it, like the new Mutex
type which I switched to in this commit.

A frame label that is hidden by links is not all that helpful.
On the other hand, if a link is partially hidden by a frame label,
that's typically not a problem at all.
Several small improvements to the layout of the search menu:
* Avoid the separator arrow on highlighted items being cutoff
* Properly center and prevent overlap of the scroll indicator
arrows at the top and bottom
* Improve robustness with different zoom levels
* Overall more unified spacing and margins

This adds an Import VDB node. It loads all the grids from a .vdb file and hence
outputs a Volume geometry instead of an individual grid.
The grids are cached through the existing volume grid file cache, so they are
automatically deduplicated when volume grids are loaded from files in other
ways.

When a new node tree becomes active based on the context, the node editor was
not centered on the new tree. This can easily lead to the situation where there
is no node visible, and the user first has to search for the nodes.
The reason for this is unexpectedly special:
* `snode_set_context` calls `ED_node_tree_start` which adds the `NC_SCENE |
ND_NODES` notifier.
* Typically, this would update the `View2D` of the region in
`node_area_listener`.
* However, `snode_set_context` is called from
`wm_event_do_refresh_wm_and_depsgraph` which happens after(!) the listeners
run. Therefore, the node editor is redrawn before the listener is handled.
* During redraw, the stored view center is overridden. When it is later used in
the listener, the value is lost already.
This patch solves this by updating the view center eagerly when opening changing
what node tree is visible, instead of trying to it lazily where the required
information might be lost already.

The copy/paste function for nodes is offsetting the node centroid to the
mouse cursor. This was skipping direct children of selected frames, because
the node position was originally relative to the frame parent. This behavior
changed in 4bf34d95, which causes child nodes to remain stuck at their
original location.
All nodes should simply be offset now, since their positions are no longer
relative.

This allows users to implement arbitrary camera models using OSL by writing
shaders that take an image position as input and compute ray origin and
direction.
The obvious applications for this are e.g. panorama modes, lens distortion
models and realistic lens simulation, but the possibilities are endless.
Currently, this is only supported on devices with OSL support, so CPU and
OptiX. However, it is independent from the shading model used, so custom
cameras can be used without getting the performance hit of OSL shading.
A few samples are provided as Text Editor templates.
One notable current limitation (in addition to the limited device support)
is that inverse mapping is not supported, so Window texture coordinates and
the Vector pass will not work with custom cameras.

Previously, it was not possible to add any of the existing zones using
link-drag-search, but only using normal search of the Add menu.
For most zones the intended behavior was fairly straight forward. Just for For
Each Element zone is a bit special, because it has two output geometries which
have different meaning.
I also had to update the link-drag-search a bit to remove the limitation that
only a single node can be added.

The goal here is to avoid having to cast to and from `ID` when getting the
evaluated or original ID using the depsgraph API, which is often verbose and not
type safe. To solve this, there are now `DEG_get_original` and
`DEG_get_evaluated` methods which are templated on the type and use a new
`is_ID_v` static type check to make sure it's only used with valid types.
This allows removing quite some verbosity on all the call sites. I also removed
`DEG_get_original_object`, because that does not have to be a special case
anymore.

This adds support for having viewer nodes in closures. The code attempt to
detect where the closure is evaluated and shows the data from there.
If the closure is evaluated in multiple Evaluate Closure nodes, currently it
just picks the first one it finds. Support for more user control in this case
may be added a bit later. If the Evaluate Closure node is in e.g. the repeat or
foreach zone, it will automatically use the inspection index of that zone to
determine what evaluation to look at specifically.
Overall, not too much had to change conceptually to support viewers in closures.
Just some code like converting between viewer paths and compute contexts had to
be generalized a little bit.

Viewer nodes in compositor now show the eye icon when they are active,
so after https://projects.blender.org/blender/blender/pulls/134949
both geometry nodes viewers and compositor viewers look the same.
The only remaining difference is that in geometry nodes, clicking on
the eye icon deactivates the viewer and the node tree output
is shown instead. This is not possible in the compositor currently,
because at least one viewer must be active in the node tree.

After creating a new shading material, the new node tree might become invisible and the user has to scroll down to see the nodes.
The idea of this PR is to create nodes with x-positions centered around zero, such that they are always visible no matter the screen size or workspace setup. Ideally, the nodes' position should depend on the region's zoom and pan. However, the node creation code currently does not depend on `SpaceNode`, so such solution would complicate the code a bit. Also, this heuristic seem to work well enough for most cases.
Note: this only affects newly created materials. The material of the default cube and the default world material still have invisible nodes sometimes. This is because they are saved in the startup file, which will be addressed in a different patch.

Since nodes are not uniquely assigned to zones (some nodes are in two
zones at the same time), it's better not to expose this detail in multiple
APIs. This avoids having to explain the behavior multiple times.
Now one just has to use `get_zone_by_node/socket` and can then use
a seperate method to get the zone stack for that zone like before.
This adds initial support for showing logged data in closures. This is more
tricky than the other zone types, because the zone content is evaluated
elsewhere. The main new thing here is a function that attempts to find where a
given closure is evaluated statically.
Finding this place statically is also important because we generally decide
which compute contexts we want to log before evaluation starts. That's because
we don't want to log everything (which is expensive), but just the places that
the user is currently looking at.
This also changed a bunch of CMakeLists.txt files so that these modules can
include NOD_* stuff, which is generally fine everywhere in editors code.

This adds a simple `compute_context_for_edittree` function that returns the
"active" compute context for the given node editor. This is used in various
places, but previously one had to construct the compute context in multiple
steps (first find the root context (modifier/operator), then handle the tree
path). Since the edittree already has a specific active context, there should be
an easy way to retrieve that.
This also adds a few extra check that avoid redundant work that was done before.

While `ComputeContextBuilder` worked well for building simple linear compute
contexts, it was fairly limiting for all the slightly more complex cases where
an entire tree of compute contexts is built. Using `ComputeContextCache` that is
easier to do more explicitly. There were only very few cases where using
`ComputeContextBuilder` would have still helped a bit, but it's not really worth
keeping that abstraction around just for those few cases.

The main goal here is to add `GeoTreeLogger.tree_orig_session_uid`. Previously,
it was always possible to derive this information in `ensure_node_warnings`.
However, with closures that's not possible in general anymore, because the
Evaluate Closure node does not know statically which node tree the closure zone
is from that it evaluates. Therefore, this information has to be logged as well.
This patch initializes `tree_orig_session_uid` the same way it initializes
`parent_node_id`, by scanning the compute context when creating the tree logger.
To make this work properly, some extra contextual data had to be stored in some
compute contexts.
This is just a refactor with no expected functional changes. Node warnings for
closures are still not properly logged, because that requires storing
source-location data in closures, which will be implemented separately.
Pull Request: https://projects.blender.org/blender/blender/pulls/137208
The original motivation for this was to prepare the API to support having more
than one tree log for each zone. Currently, there is always a well defined tree
log for each zone (when the inspection index is taken into account). However,
for closures that is less true and there may be more than one equaly valid tree
log. While we might still want to show only one value per socket initially, it
would probably be nice in the future to support accessing information from
multiple evaluations at the same time (also for loops).
None of this is implemented here though, it's just a refactor with no expected
functional changes.

The compositor does not compute node previews even after the user
enables previews using the eye operator in the node header. That's
because the operator does not tag the node for update. To fix this, tag
the node for a property update and submit relevant WM notifiers.
