These changes introduce the new `BLT_I18NCONTEXT_TIME` translation
context.
They also remove `BLT_I18NCONTEXT_VIRTUAL_REALITY`, which I added at
one point but then couldn't find which messages I wanted to fix with
it.

When creating nodes by dragging a link, it can be convenient to
transfer values from input socket. For reference values, like images,
this may be necessary to avoid unnecessary data-block users. This
patch starts adding such a system. At this moment this only makes sense
for one node (Image Input), but this can be extended to work with other
reference types, different non-reference types and support auto-casting
(if a float is transferred to the Integer Input node).

Previously the only way to control the subtype was to remove the group
input or output and create it again. This commit adds a dropdown to
change an existing socket, for supported socket types.

It was necessary to fix the UI code slightly; the layout's context
wasn't being used in calls to an operator's enum items callback.

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
This changes the Switch node so that it is implemented directly as a lazy-function,
instead of as a normal geometry node which uses `GeoNodeExecParams`. This improves
the design of the layered execution api, where different nodes can be implemented
at a proper different abstraction level. The simplest kinds of nodes are implemented
as multi-function, then there is `GeoNodeExecParams` and more specialized nodes are
implemented as lazy-function. The switch node is special in the sense that it currently
needs extra behavior in the lazy-function graph generation anyway.
`GeoNodeExecParams` can be simplified as well, because the Switch node was the only
one that used the `lazy_` methods.
We could consider adding back lazy-input functionality to normal geometry nodes
as it becomes necessary. Ideally, that could be integrated with the node declaration.
Pull Request: https://projects.blender.org/blender/blender/pulls/105696
Invalid nodes are not added to the lazy-function graph. Therefore, their
outgoing links are also not added, which implies that the targets need
some default value.
Add a per node type callback for creating node add search operations,
similar to the way link drag search is implemented (11be151d58).
Currently the searchable strings have to be separate items in the list.
In a separate step, we can look into adding invisible searchable text
to search items if that's still necessary.

Something went wrong here, seems like this commit merged the main branch

I merged 3.6 into 3.5 by mistake. Basically I had a PR against main,
then changed it in the last minute to be against 3.5 via the

Original Pull Request: #104889
Note that the node group has its sockets names
translated, while the built-in nodes don't.
So we need to use data_ for the built-in nodes names,
and the sockets of the created node groups.
Pull Request #104889
Versioning code in `do_versions_after_linking_260` inserted new group input
and output nodes. And (reasonably?) expected sockets to exist on those nodes.
However, `nodeAddStaticNode` did not initialize sockets on nodes with that use
`declare_dynamic` yet. This patch changes it so that `declare_dynamic` is used
in more places, which caused issues during file loading when node groups are
updated in somewhat arbitrary order (not in an order that is based on which
groups use which).

The code removed here was intended to be an optimization that
avoids creating an additional node to join multiple attribute sets.
However, that optimization did not work, because it did not take
into account whether the single attribute set is required or not.
Allow to explicitly swap node links by pressing the alt-key while
reconnecting node links. This replaces the old auto-swapping based on
matching prefixes in socket names.
The new behavior works as follows:
* By default plugging links into already occupied (single input)
sockets will connect the dragged link and remove the existing one.
* Pressing the alt-key while dragging an existing node link from one
socket to another socket that is already connected will swap the
links' destinations.
* Pressing the alt-key while dragging a new node link into an already
linked socket will try to reconnect the existing links into another
socket of the same type and remove the links, if no matching socket
is found on the node. This is similar to the old auto-swapping.
Swapping links from or to multi input sockets is not supported.
This commit also makes the link drag tooltip better visible, when using
light themes by using the text theme color.

This was not done originally, because one had to iterate over all curves
to get the number of points which had some overhead. Now the number
of points is stored all the time anyway.
The `fix_link_cycles` function added in rB2ffd08e95249df2a068dd did not
handle the case correctly when there are multiple cycles going through
the same socket.
Since a year and a half ago we've been switching to a new way to
represent what sockets a node should have called "declarations"
that's easier to use, clearer, and more flexible for upcoming
features like dynamic socket counts or generic type sockets.
All builtin nodes with a static set of sockets have switched, but one
missing area has been group nodes and group input/output nodes. These
nodes have **dynamic** declarations which change based on their
properties or the group they're inside of. This patch addresses that,
in preparation for using the same dynamic declaration feature for
simulation nodes.
Generally there shouldn't be user-visible differences, but one benefit
is that user-created socket descriptions are now visible directly in
the node editor for group nodes and group input/output nodes.
The commit contains a few changes:
- Add a node type callback for building dynamic declarations with
different arguments
- Add an `Extend` socket declaration for the "virtual" sockets used
for connecting new links
- A similar `Custom` socket declaration is used for addon-defined socket
- Simplify the node update loop to use the declaration to build update
sockets
- Replace the "group update" functions with the declaration building
- Move the node group input/output link creation to link drag operator
- Make the field status part of group node declarations
(not for group input/output nodes though)
- Some fixes for declarations to make them update and build properly

Since internal links are only runtime data, we have the flexibility to
allocating every link individually. Instead we can store links directly
in the node runtime vector. This allows avoiding many small allocations
when copying and changing node trees.
In the future we could use a smaller type like a pair of sockets
instead of `bNodeLink` to save memory.

This moves all multi-function related code in the `functions` module
into a new `multi_function` namespace. This is similar to how there
is a `lazy_function` namespace.
The main benefit of this is that many types names that were prefixed
with `MF` (for "multi function") can be simplified.
There is also a common shorthand for the `multi_function` namespace: `mf`.
This is also similar to lazy-functions where the shortened namespace
is called `lf`.
Previously, the lifetimes of anonymous attributes were determined by
reference counts which were non-deterministic when multiple threads
are used. Now the lifetimes of anonymous attributes are handled
more explicitly and deterministically. This is a prerequisite for any kind
of caching, because caching the output of nodes that do things
non-deterministically and have "invisible inputs" (reference counts)
doesn't really work.
For more details for how deterministic lifetimes are achieved, see D16858.
No functional changes are expected. Small performance changes are expected
as well (within few percent, anything larger regressions should be reported as
bugs).

This is part of D16858 but is also useful for other purposes.
The changes to the node declaration in this commit allow us to figure
out which fields might be evaluated on which geometries statically (without
executing the node tree). This allows for deterministic anonymous attribute
handling, which will be committed separately. Furthermore, this is necessary
for usability features that help the user to avoid creating links that don't
make sense (e.g. because a field can't be evaluated on a certain geometry).
This also allows us to better separate fields which depend or don't depend
on anonymous attributes.
The main idea is that each node defines some relations between its sockets.
There are four relations:
* Propagate relation: Indicates that attributes on a geometry input can be
propagated to a geometry output.
* Reference relation: Indicates that an output field references an inputs field.
So if the input field depends on an anonymous attribute, the output field
does as well.
* Eval relation: Indicates that an input field is evaluated on an input geometry.
* Available relation: Indicates that an output field has anonymous attributes
that are available on an output geometry.
These relations can also be computed for node groups automatically, but that
is not part of this commit.
When these declarations are built without the help of the special
builder class, it's much more convenient to set them directly rather
than with a constructor, etc. In most other situations the declarations
should be const anyway, so theoretically this doesn't affect safety too
much. Most construction of declarations should still use the builder.
Whenever a node group is entered during evaluation, a new compute
context is entered which has a corresponding hash. When node groups
are entered and exited a lot, this can have some overhead. In my test
file with ~100.000 node group invocations, this patch improves performance
by about 7%.
The speedup is achieved in two ways:
* Avoid computing the same hash twice by caching it.
* Invoke the hashing algorithm (md5 currently) only once instead of twice.
Geometry nodes used to log all socket values during evaluation.
This allowed the user to hover over any socket (that was evaluated)
to see its last value. The problem is that in large (nested) node trees,
the number of sockets becomes huge, causing a lot of performance
and memory overhead (in extreme cases, more than 70% of the
total execution time).
This patch changes it so, that only socket values are logged that the
user is likely to investigate. The simple heuristic is that socket values
of the currently visible node tree are logged.
The downside is that when the user changes the visible node tree, it
won't have any logged values until it is reevaluated. I updated the
tooltip message for that case to be a bit more precise.
If user feedback suggests that this new behavior is too annoying, we
can always add a UI option to log all socket values again. That shouldn't
be done without an actual need though because it takes up UI space.
Differential Revision: https://developer.blender.org/D16884
Use socket indices to keep track of logged values instead of their
identifiers. This decreases memory pressure when there are many
sockets. In cases with many cheap nodes, this can give a relatively
large improvement to overall performance. We observed a 15% increase
in a case with many math nodes and a larger increase in an experimental
softbody node setup. The log is invalidated when we add/remove/move
sockets anyway.
This is the best way I found to make building socket declarations without
the builder helper class work. Besides a vague hope for non-leaky
abstractions, I don't think there's any reason for these fields not to be
accessible directly.
Ref D16850
Separate the "insert nodes into group" operation into more distinct
phases. This helps to clarify what is actually happening, to avoid
redundant updates to group nodes every time a new socket is discovered,
and to make use of the topology cache to avoid the "accidentally
quadratic" alrogithms that we have slowly been removing from node
editing.
The change is motivated by the desire to use dynamic node declarations
for group nodes and group input/output nodes, where it is helpful to
avoid updating the declaration and sockets multiple times.
