This adds support to render Curves attributes in EEVEE.
Each attribute is stored in a texture derived from a VBO. As the
shading group needs the textures to be valid upon creation, the
attributes are created and setup during its very creation, instead
of doing it lazily via create_requested which we cannot rely on
anyway as contrary to the mesh batch, we do cannot really tell if
attributes need to be updated or else via some `DRW_batch_requested`.
Since point attributes need refinement, and since attributes are all
cast to vec4/float4 to account for differences in type conversions
between Blender and OpenGL, the refinement shader for points is
used as is. The point attributes are stored for each subdivision level
in CurvesEvalFinalCache. Each subdivision level also keeps track of the
attributes already in use so they are properly updated when needed.
Some basic garbage collection was added similar to what is done
for meshes: if the attributes used over time have been different
from the currently used attributes for too long, then the buffers
are freed, ensuring that stale attributesare removed.
This adds `CurvesInfos` to the shader creation info, which stores
the scope in which the attributes are defined. Scopes are stored
as booleans, in an array indexed by attribute loading order which
is also the order in which the attributes were added to the material.
A mapping is necessary between the indices used for the scoping, and
the ones used in the Curves cache, as this may contain stale
attributes which have not been garbage collected yet.
Common utilities with the mesh code for handling requested
attributes were moved to a separate file.

Since rBb47c5505aa37, Batchs containing GPUIndexBuf initialized via
a PyObject with buffer protocol no longer work.
This was because of an unsafe optimization in the GPUIndexBuf module
for Python.
So remove this micro-optimization.
When saving from the menu the region was not set,
causing the last region in `area->regionbase` to be used
as the region was assigned before comparison.
* Port over new code tables from Cycles
* Convert Rec.709 to scene linear for lookup table.
* Move code for wavelength and blackbody to IMB so they can access the
required transforms, which are not in blenlib.
* Remove clamping from blackbody shader to bypass the texture read.
Since it's variable now easiest to just always read from the texture
than pass additional parameters.
* Fold XYZ to RGB conversion into the wavelength table.

This reverts commit 14a5a91e0e.
This caused build errors on x64+arm mac builds and some versions
of MSVC, reverting for now till a better solution is found.
917c096be6 applied to objects only, this also applies the same fix for
the general 3D View drop operations, e.g. used for dragging materials,
images, worlds, etc.
This is needed to fix T95706, but apparently something else is still
going on. Needs further investigation.
The operators to handle object drag and drop (from the asset browser,
outliner, etc.) used the object name to find the object to add and
place. This is problematic with linking and/or library overrides, since
this may lead to multiple objects with the same name. So the wrong
object would be used by the drop operators.
Partially fixes T97320. T95706 probably needs the same fix but for
materials.
As a side-effect, the "Name" button won't show up in the Adjust Last
Operation panel anymore. This isn't really useful, and I doubt this was
ever intentionally exposed in the UI.

The importer was not doing a notification that the scene has changed, so
the bottom status bar scene stats info was not updated right after the
new OBJ import.

This patch makes it possible to change the precision with which to
store volume data in the NanoVDB data structure (as float, half, or
using variable bit quantization) via the previously unused precision
field in the volume data block.
It makes it possible to further reduce memory usage during
rendering, at a slight cost to the visual detail of a volume.

Using the atomic "compare and swap" method in add_triangles stage
dramatically speeds up the add_triangles call and significantly reduced
the overall calculation time. This is currently the fastest method we

Steps to reproduce were:
- Open Clip Editor
- Call "Open Clip" (e.g. Alt+O)
- Select video file
The file wouldn't be loaded into the Clip Editor.
Caused by 7849b56c3c.
This is part of a fix for T88570, where the file selector would crash
when activated multiple times.
Calling save multiple times would free the operator, leaving a dangling

Existing code to replace the file operation was failing when done from
the window for the file operation itself.
Basically, this patch does two things:
- Implement a well defined window context to use as the "owner" or
"root" of the File Browser. This will be used for managing the File
Browser and to execute the file operation, even after the File Browser
was closed.
- Ensure the context is valid when dealing with file File Browser event
handlers.
Previously the window context just wasn't well defined and just happened
to work well enough in most cases. Addressing this may unveil further
issues, see T88570#1355740.

This should decrease cognitive load because:
- Intention is more explicit
- Shorter visual scope of branches (no need to search for matching
closing brackets and `else` blocks)
- Visually less busy code because condition-checks and code that
"actually does things" are separated, with less indentation
- Avoids chaining together a bunch of conditions to a single `if`
Also: Use `const`, correct comment placement, whitespace improvements.
`BKE_nlastrip_find_active()` and `update_active_strip()` now do a more
thorough search for the active strip, by also recursing into
meta-strips.
There were some assumptions in the NLA code that the active strips is
contained in the active track. This assumption turned out to be false:
when there is a meta-strip, the active strip could be inside that, and
then it's not contained in `active_track.strips` directly.
Apart from the above, there are other situations in which the track
pointed to by `AnimData::act_track` does *not* contain the active strip
(even indirectly).
Both these cases can happen when the transform system is moving a strip
that's in tweak mode. Entering tweak mode doesn't just search for the
active track/strip, but also falls back to the last-selected ones. This
means that the track/strip pointers & flags can be out of sync with
what's being tweaked/transformed. Because of this, the assumption that
there is any relation between "active strip" and "active track" has been
removed from the `update_active_strip()` function.
All this searching could be prevented by passing the `AnimData` to the
code that duplicates tracks & strips. That way, when the active
track/strip is dup'ed, the `AnimData` pointers can be updated as well.
That would require more refactoring and thus could introduce other bugs,
so that's left for later.
This patch adds 4th option to Time offset modifier Modes.
It loops from start frame to end frame and then back to start in reverse direction.
In other words it is a combination of Normal and Reverse mode.
Especially with offset control it adds the ability to create easy looping animations such as cheering crowds, flowers opening and closing at different offsets.

There are two issues. The biggest one was that a pixel value was used
to compare a squared distance meaning the tolerance was too strict.
The other issue was that the tolerance in pixels was different to what
the tracking mode is using.
The user-level change is that now it should be easier to tweak the
mask shape.
This is a place where the API function and operator should differ, for the API
manually setting the filepath and then saving should work. For the UI there is
no filepath visible, so it should open Save As even if there was a filepath set
for example from before changing an image type to Generated.
Some RNA property update callbacks can already generate such modifier,
and only one is allowed per object, so had to adapt code actually adding
new modifiers in liboverride apply codebase.
Also fixed an unreported issue of incorrect interpolation of thickness.
