Remove long-deprecated constraints that will likely never be
implemented in this form.
- Rigid Body Joint Constraint was removed in 2.80, but some references
remained in the code. Versioning code was written that tried to
remove them on load, but since constraint initialization code sets
the type to CONSTRAINT_TYPE_NULL before versioning gets a chance,
the versioning code ended up never running. This has all been
removed.
- Python/Script Constraint never worked since 2.50 and showed an error
message in the UI panel.
These constraints now load as 'null' constraint, as seems to be
(looking at the code) the way that Blender currently deals with
removed constraint types. These still show up in the outliner and
python API, but have no UI panel. Removing such constraints completely
will be left for another time, as it is beyond the scope of removing
these two specific constraint types.

Some paths in Blender support the `//` prefix for blend-file relative
paths however this is not communicated anywhere.
Support declaring this with a new flag which can be applied to filepath
& dirpath typed properties.
This is used to:
- Show red-alert when "//" are used in paths which don't support a relative prefix.
- Show a warning in the tooltip that the relative suffix is used when unsupported.
- Python warns if this prefix is ever used in an assignment or
function argument.

Prior to this commit, whether or not a brush was capable of using
certain options in Sculpt mode and whether or not these properties would
be shown to the user was spread across a number of files and
inconsistently applied.
This commit moves most of these checks to the bke::brush namespace so
that we have a single source of truth for these checks.
In total this commit:
* Changes all BrushCapabilitiesSculpt methods to use the equivalent
bke::brush function
* Removes brush type macros
* Renames BKE_brush_supports_secondary_color to fit the new pattern
* Refactors inverted logic for the `direction` property

Vulkan backend is progressing quickly. Lately we improved the
performance and finalized OpenXR support. Removing these
unsupported/limited features from Preferences->System.
The Vulkan backend is still mentioned to be experimental. Removing it as
experimental option requires some more discussions and user feedback.
Panel toggles have a subpanel for listing out properties associated with their
Boolean checkbox.
The vertical spacing for properties in this panel is slightly different to how
normal Boolean sockets list their properties. This patch makes it more
consistent by putting the properties after `Default` in a `column` sublayout.

The "Active Spline" panel used to be inside curve properties tab,
however the property is dependent on spline selection, so it makes more
sense to put this panel in the viewport, just below the "Transform"
panel, in edit mode this panel also edits active element so visually
they belong together.

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.

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

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.

In Geometry Nodes a geometry is represented by a `GeometrySet`. This is a
container that can contain one geometry of each of the supported types (mesh,
curves, volume, grease pencil, pointcloud, instances). It's possible for a
`GeometrySet` to contain e.g. a mesh and a point cloud.
This patch creates a Python wrapper for the built-in `GeometrySet`. For now,
it's main purpose is to consume the complete evaluated geometry of an object
without having to go through complex hoops via `depsgraph.object_instances`. It
also also allows retrieving instances that have been created with legacy
instancing systems such as dupli-verts or particles.
In the future, the `GeometrySet` API could also be used for more kinds of
geometry processing from Python, similar to how we use `GeometrySet` internally
as generic geometry storage.
Since we can't really have constness guarantees in Python currently, it's
enforced that the `GeometrySet` wrapper always has its own copy of each geometry
type (so e.g. it does not share a `Mesh` data-block pointer with any other place
in Blender). Without the copy, changes to the mesh in the geometry set would
also affect the evaluated geometry that Blender sees. The copy has a small cost,
but typically the overhead should be low, because attributes and other run-time
data can still be shared. This should be entirely thread-safe, assuming that no
code modifies implicitly shared data, which is forbidden. For historic reasons
there are still cases like #132423 where this assumption does not hold in all
cases. Those cases should be fixed. To my knowledge, this patch does not
introduce any new such issues or makes existing issues worse.

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.)
