The poll function for `NODE_PT_node_tree_interface_panel_toggle` looks at the
first child item and checks if it has the `is_panel_toggle` property set to
`True`. This fails if the first child is a panel, which doesn't have that
property.
The fix is to simply fall back to returning False if the first child item does
not have the aforementioned property.

This commit allows to specialize or optimize properties editor for
particular workflows by hiding individual tabs. The filtering is done on
editor level, currently in editor options popover panel.
Primary motivation was to allow strip properties to be moved to
properties editor. The filtering is beneficial, as usually it does not
make sense to show strip propeties in modelling workspace and in video
editing workspace other properties would introduce quite a bit of noise.

The capitals were only used for API compatibility when the add menu
was first added, they're not needed for new menus. Better to avoid
since they're non-standard for menu names.
Adds a new node to set the Grease Pencil depth ordering.
Here are the options:
* 2D Layers: Uses the Layer order + Stroke order to calculate the depth ordering.
* 3D Location: Uses the 3D position of the points as the depth.
This reflects the same setting that is available in the Grease Pencil
object-data properties.
The node is added to the `Grease Pencil` > `Write` menu.

The gaps between editors need to be selected and manipulated in order
to resize areas. How wide these need to be depends on the accuracy and
resolution of your pointing device. And also on the fine motor control
and visual acuity of the user. If you are using a tablet pen, touch
device, or are visually or physically challenged, then you need these
gaps to be wider. This PR allows a wide latitude in this.

The "new/duplicate" button in the Action Slot selector did not actually
duplicate, and always acted as a "new" button.
This introduces the RNA function `ActionSlot.duplicate()`, which takes
care of duplicating all the animation data associated with the slot as
well. The semantics of this function should remain valid in the
future, when Actions support multiple layers & strips. Note that this
new function does not assign the slot, it just duplicates it and its
data. The assignment of this duplicated slot is done in Python,
through the already-existing API for this.

Adds a new `Set Grease Pencil Color` node.
It was already possible to write to the color and opacity attributes using the
`Store Named Attribute` node, but this required the user to know the names
of the "built in" attributes.
Similar to how we can set other built-in attributes (e.g. the curve radius) this
adds a node to write to the following Grease Pencil attributes:
* `vertex_color` (point domain): The color of a point (the alpha value is used
as a mix factor with the base material color).
* `opacity` (point domain): The opacity of a point.
* `fill_color` (curve domain): The fill color of a stroke (the alpha value is used
as a mix factor with the base material color).
* `fill_opacity` (curve domain): The fill opacity of a stroke.
For consistency with other nodes, there is a mode to switch between writing
to the points (`Stroke` mode) and the fills (`Fill` mode).

Add a "Pixel Density" sub-panel to render output settings which
can be used to set the density (as pixels per inch for example).
This is then written to images that support pixel density.
Details:
- The scene has two values a PPM factor and a and base unit.
- The base unit defaults to pixels per inch as this is the most
common unit used.
- Unit presets for pixels per inch/centimeter/meter are included.
- The pixel density is stored in the render result & EXR cache.
- For non 1:1 aspect renders, the density increases on the axis
which looks "stretched", so the PPM will print the correct
aspect with non-square pixels.

**Problem**
When using Texture Paint mode, the Image Editor will show a UV Wireframe
to display the active object's UVs. In every other mode, this wireframe
is absent. This is currently a big problem for Sculpt Mode since the
Experimental Texture Paint system is a part of that mode, meaning that
the user can't see their UVs while they paint in Sculpt Mode. This is
also troublesome for users that would like to quickly view an object's
UVs without using Texture Paint Mode.
**Solution**
Since it's useful to be able to view an object's UVs at all times, the
Image Editor should display UV Wireframes in all Object Modes regardless
of the Image Editor's mode. This is the best solution since it means
that future Blender features, that would benefit from having a preview
of an object's UV Wireframes, will automatically have that option since
UV Wireframes are supported in all modes. Also, if a user doesn't want
to see UV Wireframes for any reason, it can be disabled with an Overlay
option.
Additionally, when multiple objects are selected, each object should
have its UV Wireframe drawn in the Image Editor. The selected objects
that aren't active should have less opaque wireframes to indicate which
wireframe belongs to the active object. This is the best approach for
having multiple objects selected since it allows the user to quickly
view the UV layout for all selected objects to troubleshoot UV problems,
like texture mapping. This is especially helpful when using a material
for multiple different objects.
An alternative solution would be to only show the UV Wireframe for the
active object, but this would be undesirable because it would make
troubleshooting UV positions tedious when working with multiple objects
since the user would need to select objects individually.

Pull Request: https://projects.blender.org/blender/blender/pulls/135102
Add a "dumb vector" storage option for custom normals, with the
"custom_normal" attribute. Adjust the mesh normals caching to
provide this attribute if it's available, and add a geometry node to
store custom normals.
## Free Normals
They're called "free" in the sense that they're just direction vectors
in the object's local space, rather than the existing "smooth corner
fan space" storage. They're also "free" in that they make further
normals calculation very inexpensive, since we just use the custom
normals instead. That's a big improvement from the existing custom
normals storage, which usually significantly decreases
viewport performance. For example, in a simple test file just storing
the vertex normals on a UV sphere, using free normals gives 25 times
better playback performance and 10% lower memory usage.
Free normals are adjusted when applying a transformation to the entire
mesh or when realizing instances, but in general they're not updated for
vertex deformations.
## Set Mesh Normal Node
The new geometry node allows storing free custom normals as well as
the existing corner fan space normals. When free normals are chosen,
free normals can be stored on vertices, faces, or face corners. Using
the face corner domain is necessary to bake existing mixed sharp and
smooth edges into the custom normal vectors.
The node also has a mode for storing edge and mesh sharpness, meant
as a "soft" replacement to the "Set Shade Smooth" node that's a bit
more convenient.
## Normal Input Node
The normal node outputs free custom normals mixed to whatever domain is
requested. A "true normal" output that ignores custom normals and
sharpness is added as well.
Across Blender, custom normals are generally accessed via face and
vertex normals, when "true normals" are not requested explicitly.
In many cases that means they are mixed from the face corner domain.
## Future Work
1. There are many places where propagation of free normals could be
improved. They should probably be normalized after mixing, and it
may be useful to not just use 0 vectors for new elements. To keep
the scope of this change smaller, that sort of thing generally isn't
handled here. Searching `CD_NORMAL` gives a hint of where better
propagation could be useful.
2. Free normals are displayed properly in edit mode, but the existing
custom normal editing operators don't work with free normals yet.
This will hopefully be fairly straightforward since custom normals
are usually converted to `float3` for editing anyway. Edit mode
changes aren't included here because they're unnecessary for the
procedural custom normals use cases.
3. Most importers can probably switch to using free normals instead,
or at least provide an option for it. That will give a significant
import performance improvement, and an improvement of Blender's
FPS for imported scenes too.

This patch supports GPU OIDN denoising in the compositor. A new
compositor performance option was added to allow choosing between CPU,
GPU, and Auto device selection. Auto will use whatever the compositor is
using for execution.
The code is two folds, first, denoising code was adapted to use buffers
as opposed to passing in pointers to filters directly, this is needed to
support GPU devices. Second, device creation is now a bit more involved,
it tries to choose the device is being used by the compositor for
execution.
Matching GPU devices is done by choosing the OIDN device that matches
the UUID or LUID of the active GPU platform. We need both UUID and LUID
because not all platforms support both. UUID is supported on all
platforms except MacOS Metal, while LUID is only supported on Window and
MacOS metal.
If there is no active GPU device or matching is unsuccessful, we let
OIDN choose the best device, which is typically the fastest.
To support this case, UUID and LUID identifiers were added to the
GPUPlatformGlobal and are initialized by the GPU backend if supported.
OpenGL now requires GL_EXT_memory_object and GL_EXT_memory_object_win32
to support this use case, but it should function without it.

This adds a new more accurate antialiasing to the Grease Pencil
render engine. This is only available for render.
This Accumulation AA doesn't replace the SMAA. SMAA is still
used by the viewport and for removing aliasing from the
depth buffer. However, using both at the same time can lead
to overblurred result.
Here are some measurements for how much the render time
increases compared to the baseline with different (SSAA) sample
counts (using an example production file, rendered at 1080p,
results might vary depending on the scene complexity):
* 8 samples: +0.14 s
* 16 samples +0.36 s
* 32 samples: +0.58 s

This implements bundles and closures which are described in more detail in this
blog post: https://code.blender.org/2024/11/geometry-nodes-workshop-october-2024/
tl;dr:
* Bundles are containers that allow storing multiple socket values in a single
value. Each value in the bundle is identified by a name. Bundles can be
nested.
* Closures are functions that are created with the Closure Zone and can be
evaluated with the Evaluate Closure node.
To use the patch, the `Bundle and Closure Nodes` experimental feature has to be
enabled. This is necessary, because these features are not fully done yet and
still need iterations to improve the workflow before they can be officially
released. These iterations are easier to do in `main` than in a separate branch
though. That's because this patch is quite large and somewhat prone to merge
conflicts. Also other work we want to do, depends on this.
This adds the following new nodes:
* Combine Bundle: can pack multiple values into one.
* Separate Bundle: extracts values from a bundle.
* Closure Zone: outputs a closure zone for use in the `Evaluate Closure` node.
* Evaluate Closure: evaluates the passed in closure.
Things that will be added soon after this lands:
* Fields in bundles and closures. The way this is done changes with #134811, so
I rather implement this once both are in `main`.
* UI features for keeping sockets in sync (right now there are warnings only).
One bigger issue is the limited support for lazyness. For example, all inputs of
a Combine Bundle node will be evaluated, even if they are not all needed. The
same is true for all captured values of a closure. This is a deeper limitation
that needs to be resolved at some point. This will likely be done after an
initial version of this patch is done.

Texture nodes are already supported through the GPUMaterial and
multi-function compositor abstractions. So we just need to expose them
through the add menu.
Add support for a 5th modifier key called "hyper",
this is a modifier supported on Wayland & X11 although
other platforms could support an additional modifier too.
Both GNOME and KDE can map CapsLock to Hyper.
Other compositors can use the XKB_DEFAULT_OPTIONS environment variable.
This allows users to have an additional modifier for their own use
that doesn't conflict with other keys.

Strip locking was meant to be used with strip transformation only. So
the check, whether strip is locked is removed from hide/unhide operator.
Further it was requested to lock sound strip subframe offset. Since this
is time related property, it was moved to time panel. This also
addresses request to make it more obvious, why the value can't be
changed.
The name of the property was clarified from "Offset" to
"Sound offset", because there are another 2 offsets in the panel.
Finally, when channel is locked, properties in side panel now reflects
this state. This is done by adding RNA get function for `Strip.lock`
property. Function `seq::transform_is_locked` is used instead of
checking `SEQ_LOCK` flag, because it also checks channel state. With
this setup, the lock property can't be disabled while channel is locked.
However strip lock flag will be unset, which can be prevented. (I am not sure which is better. Both are fine in my eyes.)

When using vertex parenting, an option for using the parent object
final evaluated indices is exposed in the Object Properties: Relations
panel. This allows the calculation of the parent vertex position to
ignore the the CD_ORIGINDEX layer and instead use the final indices
that may have been altered by the node tree evaluation.
The indices that will be used for the vertex parenting are also exposed
to the UI in the same panel, allowing them to be altered after the
vertex parent has been created.
This adds icons for ICON_RGB_RED, ICON_RGB_GREEN, and ICON_RGB_BLUE
that display with those colors. This does not remove the existing
monochrome ICON_COLOR_* icons. This also allows the translation of
the "R", "G", "B" characters shown, for languages that prefer color
words that do not start with these.

Adds options to the new Import Settings popover (added in 7a6beb65f4)
to toggle collection instancing for dragging in collections. It can be
toggled separately for linking and appending, since it's typical to use
instancing for linking, but not appending (current default, also with
this change).
Previously, toggling collection instancing was only possible via the
Adjust Last Operation panel but this wasn't obvious, many people were
not aware. Adding this option based on feedback by the Blender Studio.

This patch adds a new Image Info node which returns information about
compositor images. The node has three sources:
The node returns the following information:
- Pixel Coordinates: The coordinates of the centers of the pixels in the
image. Those are essentially the integer coordinates with half pixels
offsets added.
- Texture Coordinates: Zero centered pixel coordinates normalized along
the greater dimension. Somewhat analogous to Object coordinates in
shader nodes.
- Resolution: The resolution of the image.
- Location: The location of the image in the virtual compositing space.
- Rotation: The rotation of the image in the virtual compositing space.
- Scale: The scale of the image in the virtual compositing space.
This node is very useful to allow greater flexibility and procedural
creations. For instance, coordinates can be used to create procedural
effects like vignette using very simple math nodes. And size can be used
to compute size-relative parameters for pixel-parameter nodes.

This patch adds common nodes that are used in Geometry Nodes and Shader
Nodes to the compositor. The following new nodes were added:
- Vector Math.
- Vector Rotate.
- Vector Mix.
- Value Mix.
- Clamp.
- Float Curve.
- Blackbody.
The follow nodes were replaced by common counterparts:
- Value.
- Color Ramp.
- Mix Color.
- Map Range.
- Math.
- Combine XYZ.
- Separate XYZ.
- Vector Curves.
Some new features were gained in the process:
- Mix Color can now clamp both factor and result.
- Map Range can map different types and interpolations.
- Vector Curves gained a new Factor input.
Some behaviors were changed:
- Map Range previously forcibly clamped values whose magnitude is larger
than the arbitrary value of 10000. This is no longer the case.
Some nodes were removed:
- Map Value. This was Map Range without the maximum 10000 limitation
followed by a Clamp node. Both are now available as nodes.
Some common nodes remain separate:
- Separate/Combine Color. Shader counterpart does not yet support all
color modes, and does not support alpha.
- RGB Curves. Shader variant does not support Film-Like curves or
Black/White balancing.
Texture nodes will also be added soon in a separate patch. Nodes that
were replaced are now deprecated but still exist and will later be
removed in v5.0. Backward compatibility code was introduced to convert
from the deprecated nodes to the new nodes.

The asset browser currently lacks a compact view that leaves names
readable. Especially when managing asset libraries (e.g. to prepare it
for sharing or set up a production library), this is quite a usability
issue. A column view like the file browser has can solve this, allowing
a quick overview and fast browsing of libraries, while keeping names
readable.
Adds a new "Horizontal List" display mode to the asset browser that
distributes assets over multiple columns, with horizontal scrolling.
Asset previews are shown in this mode, plus an asset type icon if
there's enough space. The size of previews and the columns can be
configured next to the display mode, for optimizing the display.
