Since b1526dd2c6, viewport renderer sets `G.is_rendering`, but VSE scene
rendering function used this to decide whether to do offscreen opengl
render or use render API. This logic was quite weak.
Use `SeqRenderData::for_render` instead of `G.is_rendering`, since it
explicitly defines whether strip rendering is invoked by F12 render job.
Since offscreen gl rendering rely on `BLI_thread_is_main()` being
true, use this to initialize `do_seq_gl` variable for clarity.
The use of render job path was further conditioned on `G.is_rendering`,
with exception of running headless, but this condition was incorrect.
This condition was reformulated as precondition, which if true, returns
`nullptr` instead of crashing.

Add a function that copies selected values to groups of values in the
result array. Add a runtime-typed version and a version for affecting
all attributes. Also make the "gather_group_to_group" follow the
same pattern.
This allows for some optimization when we know
some effects are not present. Also this is needed
to detect the case when world contains absorption
in order to disable distant lighting.

Add an "Index Switch" node which is meant as a simpler version of
the "Menu Switch" from #113445 that doesn't allow naming items
or displaying them in a dropdown, but still allows choosing between
an arbitrary number of items, unlike the regular "Switch" node.
Even when the Menu Switch is included (which should be in the
same release as this), it may still be helpful to have explicit mapping
of indices, and a fair amount of the internals can be shared anyway.

Currently we have options to transfer the paint mask, face sets, and
color attributes to the new mesh created by voxel remesh. This doesn't
make use of the generic attribute design, where it would be clearer to
transfer all attributes with the same methods. That's reflected in the
code as well-- we do duplicate work for the mask and vertex colors, for
example.
This commit replaces the transfer options with a single checkbox for
all attributes. All attribute types on all domains are transferred with
basically the same method as the "Sample Nearest" node from geometry
nodes-- they take the value from the nearest source element of the same
domain. Face corners are handled differently than before. Instead of
retrieving the mixed value of all the corners from the nearest source
vertex, the value from the nearest corner of the nearest face.
---
Some timing information, showing that when interpolating the same
data, the attribute propagation is significantly faster than before.
Edge and corner attributes would add some cost (edges more than
corners), but might not always be present.

When the new rotation socket is connected to another rotation socket
already, a conversion node is unnecessary. Check this in addition to the
existing "non-self" implicit conversions.
In Simple Solidify's mode edge weights created by "Bevel Convex"
disappear, if edge weight is added to original mesh. From technical
side problem is identical to the one in #114860.
If original mesh doesn't have layer "bevel_weight_edge" option "Bevel
Convex" works fine. All bevels disappear after one edge gets bevel
weight. Except ones corresponding newly added weight. In patched
version weights created by "Convex Bevel" stay. Also manually added
weight can be observed on the edge of inner cube.
Second problem is when am original plane has one vertex with bevel
weight 1.0, but no bevel in result. If to change Solidify's mode from
"Simple" to "Complex" bevel appears. Patch adds this behavior to the
"Simple" mode.

This patch rewrites the Inpaint node in the Realtime Compositor. The old
method suffered from discontinuities and singularities in the inpainting
regions. Furthermore, it ignored semi-transparent areas.
The new method is inspired by a two pass method described by the paper:
Rosner, Jakub, et al. "Fast GPU-based image warping and inpainting for
frame interpolation." International Conferences on Computer Graphics,
Vision and Mathematics. 2010.
In particular, we first fill the inpainting region using jump flooding,
then we apply a variable size blur pass whose size is proportional to
the distance to the inpainting boundary. The smoothed region is then
mixed with the input using its alpha.
The new method is much closer to the Bertalmio-style diffusion-based
inpainting methods, and thus can more accurately close holes than
existing methods.
The aforementioned method requires variable size blur, which is quite
expensive for this use case, so a new implementation was added that
approximates the method using a separable implementation, which provides
a visually pleasing result assuming a sufficiently smooth radius field,
which is true for our case since the field is an SDF.

Caused by error in refactor commit 4d668e6825. Offsets are drawn
outside of strip boundary, but strip content range in drawing context
is clamped by handles, so nothing was drawn.
Also this feature was not working, when using solo feature. This was
caused by another refactor e39cc78313. `special_seq_update` global
variable was declared in both files after splitting them, but set only
in one of them. Use `ED_sequencer_special_preview_get()` instead of
accessing variable directly.
Similar to [0], but also including the further optimizations from [1],
parallelize the vertex to edge, vertex to face, and edge to face
topology map index creation (the first part of the maps was already
parallelized). Vertex to face index creation went from 9.8 ms to 1.7 ms
on average, for a 1 million vertex grid. That's nice, since this map
is used for vertex normals after [2].

This loop might be 7x faster (not whole node).
All other code is already parallel, not sure why this was disabled.
Potentially, this was missed after some cleanup.

Remove unnecessary N^2\n complexity. Disjoint set will join all
elements in list, even without fully-related joins. Usually cost is
small (10%~ for this specific function), but some certain files might
be 10000x slower. But that is very corner case.

Ensure all Closures are filled with correct values,
like the principled bsdf node already does.
The main reason is that the new AgX color transform doesn't play well
with negative values (see #113220), but it's probably best to ensure we
use sanitized values in the rendering code as a whole.

This add the displacement option to EEVEE materials.
This unifies the option for Cycles and EEVEE.
The displacement only option is not matching cycles
and not particularly useful. So we decided to not
support it and revert to displacement + bump.

Expose the ID type identifier as defined by the `rna_enum_id_type_items`
enum items as `ID.id_type` in RNA.
Add some test to `id_management` ensuring that all ID types exposed in
`bpy.data` have a valid `id_type` value, i.e. that they have a matching
entry in `rna_enum_id_type_items`.
This will hopefully prevent future cases like #115151 .
Especially on windows, direct output to `cout` via `<<` is very expensive.
Instead, use fmtlib to do all formatting into a no-alloc `fmt::memory_buffer`,
and output that with one call to `cout`.
timeit utilities are not used much by default, but during development or
profiling one often uncomments macros like `DEBUG_TIME` that then enable
`SCOPED_TIMER` or `SCOPED_TIMER_AVERAGED`.
Having one `SCOPED_TIMER_AVERAGED` inside sequencer `draw_channels`, with
empty timeline and all default channels; the overhead in % of `draw_channels`
duration of said scoped timer before and after this change:
- Windows: 29% -> 5%
- Mac: 5.0% -> 4.4%

This uses the principles outlined in
Screen Space Indirect Lighting with Visibility Bitmask
to compute local and distant diffuse lighting.
This implements it inside the ray-tracing module as a fallback when the
surface is too rough. The threshold for blending between technique is
available to the user.
The implementation first setup a radiance buffer and a view normal
buffer. These buffer are tracing resolution as the lighting quality is
less important for rough surfaces. These buffers are necessary to avoid
re-projection on a per sample basis, and finding and rotating the
surface normal.
The processing phase scans the whole screen in 2 directions and outputs
local incomming lighting from neighbor pixels and the remaining
occlusion for everything that is outside the view.
The final steps filters the result of the previous phase while applying
the occlusion on the probe radiance to have an energy conserving mix.

Before #112901, subsurface scattering was skipped if its radius was
less than 1 pixel.
Aside from an optimization, this also avoided divisions by zero in
`burley_eval`.
This just brings back the early return when `pixel_footprint < 1.0`.

When animators want to key something in the viewport,
the code needs to know *which properties* should be keyed of that selected thing.
So far that was done with keying sets, and a pop-up that let's
you choose the keying set to use. You can get rid of the popup by
choosing a keying set ahead of time. But that is also not always desirable.
That pop-up is quite confusing and gives way too many options.
To simplify this process this PR adds a User Preference option to choose one or more of:
* Location
* Rotation
* Scale
* Rotation Mode
* Custom Properties
Now whenever the `I` key is pressed in the viewport,
and no keying set is enabled, it reads the preferences for which channels to insert.
# User Facing changes
* The popup will not be shown when pressing the hotkey,
but you can still explicitly use keying sets by going to the menu
* Which channels are keyed is defined by a User Preference setting under animation
* when a keying set is used explicitly, the User Preference settings are ignored
