This changes the menu switch socket to use the socket-items system
(`NOD_socket_items.hh`) that is already used by the simulation zone, repeat
zone, bake node and index switch node. By using this system, the per-node
boilerplate can be removed significantly. This is especially important as we
plan to have dynamic socket amounts in more nodes in the future.
There are some user visible changes which make the node more consistent with
others:
* Move the menu items list into the properties panel as in 0c585a1b8a.
* Add an extend socket.
* Duplicating a menu item keeps the name of the old one.
There is also a (backward compatible) change in the Python API: It's now
possible to directly access `node.enum_items` and `node.active_index` instead of
having to use `node.enum_definition.enum_items`. This is consistent with the
other nodes. For backward compatibility, `node.enum_definition` still exists,
but simply returns the node itself.
Many API functions from `NodeEnumDefinition` like
`NodeEnumDefinition::remove_item` have been removed. Those are not used anymore
and are unnecessary boilerplate. If ever necessary, they can be implemented back
in terms of the socket-items system.
The socket-items system had to be extended a little bit to support the case for
the menu switch node where each socket item has a name but no type. Previously,
there was the case without name and type in the index switch node, and the case
with both in the bake node and zones. The system was trivial to extend to this
case.

This has some benefits:
* Nodes with dynamic socket amounts can remain more self-contained
(2 fewer files to edit with this patch).
* It's easier to reuse existing C++ code, reducing redundancy.
One new thing I'm doing here is to define operators in node files. It seems
reasonable to register operators that belong to a node together with that
node. Without this, code spreads out further than necessary without any real benefit.
This patch affects the simulation zone, repeat zone, bake node and index switch node.
The UI is slightly affected too. Since we had the UI defined in Python before,
it wasn't possible to integrate it into the node properties panel. That is possible
now and looks better anyway. The previous UI was an artifact of technical limitations.

This PR adds a polyline hide operator for sculpt mode as well as the
necessary generic callback code to allow using this gesture in other
selection tools.
Added features include:
* *Polyline Hide* operator
* `WM_gesture_polyline_*` callback functions for other operators
* Status bar text while using the polyline modal
* Common *Gesture Polyline* keymap for usage with the modal
Unlike the *Box Hide* and *Lasso Hide* operators, the *Polyline Hide*
operator does not provide a simple shortcut to click and show all
hidden elements in a mesh. This is because the existing operators
operate on a click-drag action while the new operator is invoked by
just a click.

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

The goal of this PR is to remove any user facing parameter
bias that fixes issues that are caused by inherent nature of
the shadow map (aliasing or discretization).
Compute shadow bias in the normal direction to avoid
both shadow leaking at certain angles or shadow
acnee.
This bias is computed automatically based on the minimum
bias amount required to remove all errors. The render
setting is removed as of no use for now.
#### Normal bias
We do the bias in world space instead of shadow space
for speed and simplicity. This requires us to bias using
the upper bound of biases for the same location in space
(using biggest texel world radius instead of UVZ bias).
This isn't much of an issue since the bias is still less
than 2 texel. The bias is still modulated by facing
ratio to the light so surfaces facing the light have no
biase.
This fixes both self shadowing and flat occluders aliasing
artifacts at the cost of moving the shadow a bit on the
side. This is the blue arrow in the diagram.
We always bias toward the normal direction instead of the
light direction. This is alike Cycles geometric offset for
the shadow terminator fix. This is better since it does'nt
modify the shading at all.
#### Slope bias
To avoid aliasing issue on zero slope receiver, we still
have to use the slope bias with a size of 1 pixel.
#### PCF filtering
We now parametrize the filter around the normal instead of
using the shadow map local space. This requires to use
a disk filter instead of box, which is also more pleasant
for most light shapes (all except rectangle lights).
Setting the filter around normal avoid overshadowing from
zero slope occluders. This cannot be fixed by more slope bias
in light space PCF. We could fix it in light space by projecting
onto the normal plane but that gives an unbounded bias when `N.L`
is near 0 which causes either missing shadows or self shadow if
using an arbitrary max offset value.
To avoid overshadowing from any surface behind the shading
point, we reflect the offset to always face the light.
Doing so instead of using the perpendicular direction
is better for very sharp geometric angles, has less
numerical precision issue, is symetrical and is cheaper.
To avoid any self shadowing artifact on zero slope receivers
with angled neighbors (like a wall and the floor), we have
to increase the slope bias according to the filter size.
This might be overkill in most situation but I don't feel
this should become a setting and should be kept in sync
with the filter. If it has to become an option, it should
simply a factor between unbiased filter and best bias.
#### Shadow terminator
The remaining artifacts are all related to shadow terminator
one way or another. It is always caused by the shading
normal we use for biasing and visibility computation not
being aligned with the geometric normal.
This is still something we need a setting for somewhere.

When passing strings to str.format(..) use `{:s}` format specifier
which only takes strings and wont run `.__str__()` on non-strings.
While `{!s}` is an equivalent to `%s`, for the most part `%s` was
used for strings, so using `{:s}` is clearer and more specific.
Part of modernizing scripts in Blender, where the previous convention
was to use percentage formatting which has become the "old" way to
format strings in Python.
See proposal for details #120453.

Updates to refactor from [0].
- Rename "_context" as it's no longer unused.
- Remove call to `iface_` as the string no longer contains text.
- Remove redundant `enumerate(..)`.
- Use ternary operator instead of a tuple lookup.
- Assign a ratio variable for reuse.

Use __repr__ for formatting file instead of __str__ because non-standard
characters will be escaped and the string will be properly quoted.
Also, a modules __file__ is not *guaranteed* to be a string
(although it almost always is), nevertheless, __repr__ generally
results more more humanly readable results.
Note that __repr__ was already used to format __file__ in most places.
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.

Use `FileHandlers` to handle file drag-n-drop in Node Editors. Drop-boxes
still remain since they handle Images ID drag-n-drop.
This also allows to open/drag-n-drop multiple files at once.
Also this will allow add-ons to also support drag-n-drop for images and
movies in node editors while still providing access to Blender's native
support since File Handlers let users choose which to invoke if there's
multiple configured.

When using a version of Wayland that doesn't support trackpad direction
show an option to set the direction manually.
While this is a stop-gap measure until compositors support seat

This implements all the sculpt tools in Grease Pencil 3.
UI changes in the 3D view header and keymap entries for sculpt mode are
still minimal, more entries should be added once the relevant operators
are supported.
A set of utility functions and a shared base class
`GreasePencilStrokeOperationCommon` for sculpt operations has been added
to make individual operations less verbose.
The `GreasePencilStrokeParams` struct bundles common arguments to reduce
the amount of boilerplate code. The `foreach_editable_drawing` utility
function takes care of setting up the parameters and finding the right
drawings, so the tool only has to modify the data. Common features like
tracking mouse movement and inverting brush influence are handled by the
common base class.
Most operations are then relatively simple, with the exception of the
Grab and Clone operations.
- __Grab__ stores a stroke mask and weights on initialization of the
stroke, rather than working with the usual selection mask.
- __Clone__ needs access to the clipboard, which requires exposing the
clipboard in the editor API.

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.

Replaces `Space Image` drop-box with a file handler in order to support
opening multiple sets of files at once and to allow users to add their

`Image_OT_open` internally. It groups files by different sequences and
UDIMs and loads each group accordingly.

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.

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.

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.

This adds clamping at the light combine stage for both direct
and indirect light.
This allows for clamping direct and indirect light separately.
While direct light clamping might not be very desirable in
EEVEE, it might be wanted to reduce the flickering from distant
shiny bumpy surfaces, or for artistic reason.
This happens after applying the BSDF throughput just like cycles.
This is done in order to minimize the performance impact and
allows to split the clamp for direct light and indirect light.
The indirect light clamp value is still used in the ray-tracing
pipeline to clamp the ray intensity. But this differs from cycles
as we clamp the ray without the BSDF throughput here. Sphere probe
have the same issues. Some more energy loss is expected compared
to the direct light clamp.
Note that we still clamp the indirect light after applying BSDF
in case the BSDF is scaling the energy up above the threshold.
This also corrects the clamping for volume that now clamps after
applying the scattering term.
Also adds clamping to volume indirect lighting.
Since we use light probe volumes for both surface and volume
indirect lighting, we need to clamp them at sampling time.

This PR implements the Cutter Tool for GPv3. The Cutter tool deletes
points in between intersecting strokes. New points are created at the
exact intersection points, so as a result the cutted strokes will fit
perfectly.
For feature parity, the tool follows the GPv2 behavior:
- The cutter tool works on all editable layers.
- Intersections are only detected for curves on the same layer,
so intersection of curves on _seperate_ layers are not handled.
Technical notes
The implementation uses the `compute_topology_change` function
created for the Hard Eraser. So at intersection points, point
attributes will be interpolated.

This PR contains 3 fixes in the tool bar for the Tint tool:
- For the tint color, the general color panel was shown, but it should
be the Grease Pencil color panel (with not just the color wheel, but
also the color palettes).
- The Advanced Brush panel was redundant, because it only showed
Radius and Strength and those are already present in the tool bar.
So the Advanced panel can be removed.
- The 'Active Layer' switch wasn't exposed in the tool bar, so it has
been added.
