It seems to think signed integers might lead to this kind of overflow,
but it's unclear why these two cases are causing warnings specifically.
Refactor the code to sidestep it.
This was caused by the cross product changing
sign in view space during planar lightprobe capture.
This can be avoided by making sure the view matrix
doesn't change handedness.

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.

Update the `ShaderCompilerGeneric` to support deferred compilation
using the batch compilation API, so we can get rid of
`drw_manager_shader`.
This approach also allows supporting non-blocking compilation
for static shaders.
This shouldn't cause any behavior changes at the moment, since batch
compilation is not yet used when parallel compilation is disabled.
This adds a `GPUWorker` and a `GPUSecondaryContext` as an easy to use
wrapper for managing secondary GPU contexts.

Blender crashes when using math interpolation functions to sample Float2
images. That's because 3 components is intentionally left out of various
switch case. To fix this, we handle 3 components and assert for expected
components count.

The gizmo is drawn in the transformed space of the gizmo (see `GPU_matrix_mul(matrix_final)` in `gizmo_cage2d_draw_intern()`). This causes initial stretching of the drawn circle. However, this initial stretching is already being compensated by drawing an ellipse, which axes are computed based on the gizmo size (see variable `margin`).
Therefore, computing the size of the gizmo (`scale_xy`) based on render dimensions (`dims`) seems to be overcompensating and introduces another stretching. This patch removes the redundant compensation.

Adding "writeback" callbacks to the depsgraph should be temporary, since these
callbacks can bind pointers that become invalid. In this case: the evaluated
nodes modifier bound by a bake node callback. These callbacks are cleared after
being added in the `deg_flush_updates_and_refresh` function, but there are other
cases where depsgraph updates are executed which don't support writeback
callbacks (`object_force_modifier_update_for_bind` run by the smooth modifier
"bind" function).
To prevent dangling invalid pointers in outdated callbacks, disallow adding
callbacks in any case other than the `deg_flush_updates_and_refresh` function.
Since callbacks can be added from any depsgraph update, the safest way to
prevent adding them is in the depsgraph itself. If the `use_writeback_callbacks`
flag is not set, any callback is simply discarded.

The compositor does not compute node previews even after the user
enables previews using the eye operator in the node header. That's
because the operator does not tag the node for update. To fix this, tag
the node for a property update and submit relevant WM notifiers.

A box mask can now be manipulated using a (rotated) rectangle gizmo.
Changes:
- Implementation is based on crop gizmo. Some functionalities were generalized for both crop and box mask (later should be used for ellipse mask as well)
- Support offset caused by transform nodes in compositor
- Support rotation for 2d gizmos
Note: a known issue about stretched rotation handle will be handled in a separate patch, see https://projects.blender.org/blender/blender/pulls/137079

This reverts commit cf55a0acdc.
While this was added with the commit that added support for tile cache,
keep the extension check as Blender can load them.
`radial_control_modal` would only actually update the target property
(via `RNA_property_update`) for the "standard" ways of confirming
(`LEFTMOUSE`, `EVT_PADENTER`, `EVT_RETKEY`).
When using "release_confirm" however, that was skipped, so added the
`RNA_property_update` now.

Caused by 9b70851d91.
That commit inadvertently switched the order of these definitions. Because the
vertex buffers created by GPU subdivision still have a different format than regular
mesh drawing (the position buffer also includes vertex normals), the order of these
VBOs in the batch matters, since "lnor" attribute can override another.

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.

This commit changes the behavior of the Clay Strips brush so that
it aligns more with expectations.
* Tilt is applied consistently to the sculpt plane instead of only being
applied if the brush is both using the calculated Sculpt plane and not
using the original normal.
* The sampled normal is used for the subsequent brush plane check
instead of being incorrect when alternate sculpt planes are used.

**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.

This fixes most "One Definition Rule" violations inside blender proper
resulting from duplicate structures of the same name. The fixes were
made similar to that of !135491. See also #120444 for how this has come
up in the past.
These were found by using the following compile options:
-flto=4 -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
Note: There are still various ODR issues remaining that require
more / different fixes than what was done here.

When resizing area, outline flickering is caught occassionally. Border edge
is not identified sometimes which doesn't set `active_area` to null.
This eventually draws outline with `TH_EDITOR_OUTLINE_ACTIVE` color.
When moving editors, always set `active_area` ptr as null to eliminate
jumping between two theme colors.

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.

Current implementation uses a CPU roundtrip to transfer render result
to the Xr Swapchain. This PR adds support for sharing the render result
on Linux systems by using file descriptors.
To extend this solution to win32 or dx handles can be done by extending
the data transfer modes, register the correct extensions. When not
using the same GPU between Blender and OpenXR the CPU roundtrip
will still be used.
Solution has been validated with monado simulator and seems to be as
fast as OpenGL.
Performance can be improved by using GPU based synchronization.
Current API is limited as we cannot chain the different renders and
swapchains.

When the collection is disabled and was only referenced by a node tree, it was
missing from the depsgraph. The Geometry Nodes modifier tried to add a relation
to it, but it couldn't because the collection was not in the depsgraph in the first place.
Now, the collection is always added to the depsgraph when it's referenced by a
node tree that's in the depsgraph too. This makes the existing code that adds the
relation from the collection to the Geometry Nodes modifier work.

The GPU compositor crashes if 1D Voronoi is used. That's because the
vector input is unavailable in that mode, but the GPU material compiler
considers all inputs, even unavailable ones. So we need to link those
sockets to some arbitrary constant value.
The Merge Animation operator assumed that when a keyframe strip exists,
it always has a channelbag for the to-be-moved slot. This isn't
necessarily the case, so now it only moves the channelbag if it exists.

The Denoise node crashes if used in the viewport compositor. That's
because OIDN uses the compositor context in a different thread, which
does not have access to the DRW context. To fix this, we assign relevant
context data to the compositor context from the DRW context before
running the evaluator, then make the compositor context return those
data instead of accessing the DRW context.
