Transport rays that enter to another location in the scene, with
specified ray position and normal. This may be used to render portals
for visual effects, and other production rendering tricks.
This acts much like a Transparent BSDF. Render passes are passed
through, and this is affected by light path max transparent bounces.

The idea is to allow iterating over e.g. all ID usages of a node from a
whole nodetree, using the same generic handling as existing 'whole ID'
`foreach_id` code.
This is necessary in some cases wher a sub-data needs to processed
independently from any 'owner ID', e.g. in some copy/paste handling.
This is a pre-requirement for proper fix of nodes copy/paste (see
e.g. #120103).

Add a "Mouse Position" node that outputs the location of the mouse
cursor in region space and the overall size of the region, both in pixel
units. Both outputs are integers to help reflect their pixel units.
If there the mouse position is ever accessible in sub-pixels, they can
easily be changed to floats.
Also add a "Wait for Cursor" option similar to the one for some built-in
operators that delay's the operator's execution until there is a mouse
click in the viewport. That way the operator can be called from menus
even though it is interactive. This option is placed in the node editor
header. When there are more options, it will be part of an "Options"
popover panel similar to the existing "Modes" and "types" popovers.
Combined with the viewport transform node, and other nodes like Raycast,
these features can allow making tools that create geometry where you
click in the scene.

Add a node that outputs the transform of the viewport relative to the
self object's transform. This node can be used to build effects like
billboarding or aligning geometry to the current view. In combination
with the mouse position node in the future it will allow tools like
generating geometry at the mouse click position.
There are two output matrices. The first is the projection matrix
that takes positions in camera space and applies the final perspective
projection. The other is the "view" matrix which contains the location
and rotation of the camera. These are separate because though their
combination is useful, it isn't used like a typical rotation/transform matrix.

For the brush assets project (#116337) all editors with brushes are
getting an asset shelf, and the brush tools are combined, with
individual brushes accessed in the shelf. That design seems way
overkill for UV sculpting which is just three very simple tools.
In order to avoid one editor with inconsistent use of brushes, which
would significantly increase the complexity of the system after the
brush assets merge, port the three UV sculpt tools to be regular
modal operators that don't use the brush or paint system at all.
To be clear, this is a compromise that doesn't feel ideal, but no
one could think of a better solution. Theoretically this removes
some flexibility from UV edit "sculpting", in practice it probably
won't be a noticeable change.

The "uniform thickness" was still in the legacy "pixel" space. The fix
makes sure that value is always converted to the right radius space.
We also convert the potentially animated property for the thickness
and scale the fcurves to be in the right space.

This moves the seemingly arbitrary value of "1 / 2000"
into a constant variable
(`bke::greasepencil::LEGACY_RADIUS_CONVERSION_FACTOR`)
so that it can be used in all the places where
legacy "thickness" values need to be converted.
This also expands the explanation of the factor a bit, so it's
clearer why it is needed.
Moving a constant variable results in a copy occurring instead. This
looks to have been an accidental change as part of ea937b304d.
A few tools will warn about this:
`Warning C26478 Don't use std::move on constant variables. (es.56)`
`Warning cpp:S5415 "std::move" should not be called on a const object.`

This PR implements the Weight Paint tools for GPv3.
Tools:
- Draw, for assigning weight to stroke points
- Blur, smooths out weight using adjacent stroke point weights
- Average, smooths weight using the average weight under the brush
- Smear, like finger painting, drags weights in the direction of the brush
- Sample weight, sets the brush weight to the weight under the cursor
The weights are assigned to the active vertex group. When there is no
active vertex group, a group is automatically created.
When the Auto Normalize option is enabled, it is ensured that all
bone-deforming vertex groups add up to the weight of 1.0.
When a vertex group is locked, it's weights will not be altered by
Auto Normalize.
The PR already supports multi frame editing, including the use of a
falloff (defined by a curve).
The implementation is in accordance with the Weight Paint tools in GPv2.

This reverts part of 36cda3b3116acba3b895daf68689f8af01b62392
and replaces the use of `OB_MODE_PAINT_GREASE_PENCIL`
`OB_MODE_PAINT_GPENCIL_LEGACY` flag instead.
The `OB_MODE_PAINT_GREASE_PENCIL` is removed.
The `GREASE_PENCIL_OT_draw_mode_toggle` operator is removed
and the `GPENCIL_OT_paintmode_toggle` operator is adapted to
work with GPv3.

As part of the brush assets project, the image editor needs an asset
shelf to display brush assets for texture paint mode. This commit adds
the unused asset shelf region, similar to the 3D viewport's region that
is currently just used for the pose library. For now, users will just
see an "Asset Shelf" toggle in the view menu.

Currently for node tools we create and evaluate a temporary depsgraph
with all the selected object data-blocks and all data-blocks referenced
by the node tree.
Needless to say, this can be very slow when those data-blocks contain
arbitrary procedural operations. Re-evaluating all the selected objects
is particularly because it will give a slowdown even in very basic uses
of node tools.
Originally I hoped that geometry nodes could be made to work with
original as well as evaluated data-blocks. But that would require far
too many tricky changes and arguably isn't right design-wise anyway.
Instead of that, this commit makes node tools dependency graph
evaluation more fine-grained in a few ways.
1. Remove the evaluation of selected objects. These are always visible
in the viewport and part of the active depsgraph anyway. To protect
against cyclic dependencies, we now compare `orig_id` instead of the
object pointer itself.
2. Evaluate the node group and its dependencies in a separate depsgraph
used only when necessary. This allows using the original node tree
without any copies when it doesn't reference any data-blocks.
3. Evaluate IDs from node group inputs (from the redo panel) in the extra
depsgraph as well, only when necessary.

This makes the read and write API functions match more closely, and adds
asserts to check that the data size is as expected.
There are still a few places remaining that use BLO_read_data_address
and similar generic functions, these should eventually be replaced as well.

With the matrix socket being introduced into geometry nodes, we
are starting to deal with more complex transforms like perspective
projection. For those matrices projecting a point is not as simple
as just matrix multiplication, there has to be an additional normalization
step after. To solve that in an intuitive way consistent with how it's
typically solved in code, add a new "Project Point" node.
The canonical use case for now is in combination with the mouse
position, viewport transform, and raycast nodes, to find where the
mouse clicked on the edited geometry.

Grease pencil runtime data stores the "current" frame in the
`eval_frame` property. This is updated before modifier evaluation, but
also used after modifiers, e.g. by the spreadsheet.
If the GeometrySet that is returned by the nodes modifier is created
during the nodes evaluation (as is the case with the Delete node) then
the resulting geometry set has `eval_frame == 0`. To fix this the
`eval_frame` is now also update _after_ modifier evaluation.
This will only set the correct `eval_frame` for the __top level__
geometry set. Other GeometrySets like instances may not have the correct
frame value. This is a more general problem with the design that is out
of scope here.

Add a simple node to compute the intersection, difference, or union
between SDF grids. This should be the first new use case for the
new volume grid nodes that wasn't possible before.
For naming and multi-inputs, the node uses the same design as the
mesh boolean node. We considered splitting each operation into a
separate node, but though most users considered these different
"modes" of the same operation.
One thing to keep in mind is that it's important for the grids to
have exactly the same transform. If they have different transforms,
the second grid must be resampled to match the first, because the
OpenVDB CSG tools have that requirement. Resampling is expensive
(for SDF grids it means a grid -> mesh -> grid round trip) and should
be avoided.

`NOD_zone_socket_items.hh` contained code for different nodes. It's better to
split this into headers per node, because that scales better. Also it helps to

This patch adds the ability to snap strips to markers. Previously, there
only existed options to snap to hold offsets and the current frame.
This snap type works identically to other snapping options by checking
for the relevant bit (here `SEQ_SNAP_TO_MARKERS`) and adding the marker
frame numbers to `snap_data->target_snap_points` within
`seq_snap_target_points_build()`.
To enable `seq_get_snap_target_points_count()` to have access to marker
information, the current Scene object is now passed to the function.

For example, the `Bake` node generally does not propagate any anonymous

The class `AnimDataConvertor` was implementing `operator bool`
to indicate "if this AnimDataConvertor is valid, i.e. can be used to process animation data from source ID".
The cleanup replaces this with a `is_vaild` function, making the
code easier to read and allowing to jump to the function definition
of `is_valid`.
Legacy GPv2 code seems to clamp the final computed radius to `0` (at
least in some cases, see e.g. line 3992 in
`gpencil_stroke_perimeter_ex`).
Add a clamping node to the generated geometry node used to mimmic the
legacy thickness adjustment in GPv3 converted data.
NOTE: There are still some artifacts in testfile used to investigate
this issue (`(Anim) 10 Picknick by Susanne Weise.blend`), that looks
like invalid radius handling on some curves ends... Clamping _may_ be
needed in other places maybe?

Fix linking & library-overriding with NLA Tweak Mode enabled. This is a
two-pronged approach:
- When linking an animated ID from a library file, and it happens to be
in NLA Tweak Mode, it is forced out of tweak mode. This ensures that
the correct Action is loaded, and that all the NLA flags are set
correctly to display the NLA animation (instead of only the tweaked
strip).
- For library overrides there is now a post-process step that runs after
all 'apply' functions have been run. This is necessary to ensure that
all the flags and pointers that NLA Tweak Mode depends on are actually
set correctly and consistently.
This also adds one utility function `BKE_nla_debug_print_flags()` that
is by now unused. It was very useful in debugging this, though, and I
think it'll be useful in the future as well.

Caused by addition of new code in 4e10aa6e71, which was not guarding
against negative frame values. The only other place that called
BKE_sound_set_scene_sound_pitch_constant_range guarded against negative
frames (added in 1fb692e896 + 49a0502f35), but generally it looks like
negative frames are a "no no" in audaspace, so just move the value
sanitization into BKE_sound_set_scene_sound_pitch_constant_range itself.

All tools in Draw Mode, Sculpt Mode and Weight Paint Mode didn't work
correctly when the position of strokes was changed by modifiers.
In technical terms this was caused by
`get_evaluated_grease_pencil_drawing_deformation()`: when not in Edit
Mode, it effectively always returned the original position of stroke points
instead of the modified ones. In this PR there is a little fix for that.

Since image vectorscope RGB mode addition (567455124d), changing
the opacity was causing the scope to get recalculated from scratch,
because opacity value was put into vecscope_rgb data directly.
Instead of that, make vecscope_rgb data only contain RGB, and fill in
the GPU vertex buffer alpha values when creating the GPU batch.
Now tweaking the scope opacity slider feels at about the same
performance as in 4.0.
