This type will be used to store mesh edges in #106638, but it could
be used for anything else too. This commit adds support for:
- The new type in the Python API
- Editing the type in the edit mode "Attribute Set" operator
- Rendering the type in EEVEE and Cycles for all geometry types
- Geometry nodes attribute interpolation and mixing
- Viewing the type in the spreadsheet and using row filters
The attribute uses the `blender::int2` type in most code, and
the `vec2i` DNA type in C code when necessary. The enum names
are based on `INT32_2D` for consistency with `INT8` and `INT32`.

The OSL GPU services implementation of noise intrinsics was missing the
overloads for derivatives and therefore OptiX pipeline creation would fail if
those were referenced.
When WITH_CYCLES_DEBUG is set to ON the following errors are
printed to the console:
E0412 15:51:22.588564 7996345 sync.cpp:737] Unknown pass Guiding Color
E0412 15:51:22.588605 7996345 sync.cpp:737] Unknown pass Guiding Probability
E0412 15:51:22.588613 7996345 sync.cpp:737] Unknown pass Guiding Average Roughness
This change fixes this by treating the guiding passes the same
way as all other passes, solving the errors and making it possible
to visualize guiding passes in the viewport later on.

After double clicking a file, user can click on a different app and
Blender will lose focus. Then it stays on splash screen. So fetch any
window instead of relying on active one to open the file.

This reverts commit 4fe2685615.
Always use the preferred_scale requested by the compositor as this
did not work so well in the intended use case (where the low resolution
monitor text was scaled down and difficult to see).
After discussion with @ZedDB, revert this change since there are cases
where either functionality might be preferred - to ensure Blender's UI
is visible on a low resolution mirrored projector for e.g.
Changing the behavior of the preferred scale makes most sense in the
compositor, instead of controlling it on a per-application basis.
- "Lens" can be a transparent object used in cameras, or specifically
its property of focal length
- "Empty" can be an adjective meaning void, or an object type. The
latter is already disambiguated using `ID_ID`
- "New" and "Old" are adjectives that can have agreements in some
languages
- "Modified" is an adjective that can have agreement in some languages
- "Clipping" can be a property of a camera, or a behavior of the
mirror modifier
- "Value" in HSV nodes, see #105113
- "Area" in the Face Area geometry node, can mean a measurement or a
window type
- "New" is an adjective that can have agreement
- "Tab" can be a UI element or a whitespace character
- "Volume" can mean a measurement or an object type. The latter is
already disambiguated using `ID_ID`
These changes introduce the new `BLT_I18NCONTEXT_TIME` translation
context.
They also remove `BLT_I18NCONTEXT_VIRTUAL_REALITY`, which I added at
one point but then couldn't find which messages I wanted to fix with
it.

Defer acting on the tag to update scale as it caused the window
to use the wrong scale on startup & exit.
GTK/KDE applications seem to postpone updating scale so use this by
default as glitches with scale tend to be caused by updating the scale
too frequently instead of not quickly enough.
There is no need to postpone these operations when configuring the frame
only postpone committing the surface change.
Deferring these operations caused flickering when moving windows
between monitors of different scale on both GNOME & KDE.
Freeing ContextEGL would attempt to free the context's EGLSurface,
which was already freed by the native-window, causing 2x bad-surface
errors on exit.
Suppress the warning by clearing the surface from releaseNativeHandles
when the surface was created by a native window.
It was that names of related "combo" operations
like Hue/Saturation/Value, *Dilate/Erode*
and Brightness/Contrast should be separated
by slashes in their names.
This patch changes this for the multiple nodes
and operators concerning Hue/Saturation/Value
across Blender.
Note1: This patch should only touch UI names
which do not need versioning and should not
break scripts.
Note2: This breaks first letter fuzzy search
for "hsv". It was noted by @HooglyBoogly that
the "/" character needs to be added to the
fuzzy search split list. Note however that such
search is already broken in Main for nodes like
Brightness/Contrast and Dilate/Erode which
already use slash separators

Updating the buffer scale increased the window size based on the
previous window scale. Since the previous scale (DPI) newly created
windows restored from a `.blend` file isn't known, don't scale the
window size when updating the window's scale for the first time.
When a window overlaps multiple outputs, always use the resolution
on the output with the highest resolution. This means Blender never
shows low resolution content up-scaled.
Share logic between fractional & non-fractional window scaling.
This also enables fractional-scaling without scaling fixed sized buffers
for compositors without support for fractional_scale_manager_v1.
Similar to 8d0920ec6d and aef0e72e5a.
In a test case with 2 million curves and 15 million points
I observed a 10x performance improvement, from 2.2s to 0.2s
to copy the data from Blender to Cycles.
Similar to 8d0920ec6d.
In a test case with 8 million points and 3 attributes, I observed
around a 9x performance improvement, from 1.8s to 0.2s to copy
the data from Blender to Cycles. For some attribute types, using
implicit sharing could remove the need to copy entirely, but removing
the overhead from the RNA API makes sense anyway.
Only use the denoised buffer for access of denoised passes, and
access the rest of the passes from the original render buffer.
This allows in-place modification of the guiding passes needed
by the denoiser without affecting the final render result pixels.

Barycentric coordinate convention was changed at some point, which is
reflected in `motion_triangle_shader.h` (1c2c468abc) but not in
`motion_triangle.h`, this is also fixed by sharing functions between the
two header files.

Similar to 4bcd59d644. This probably got worse recently with
the generic attribute refactors for `Mesh`, but the final performance is
probably much better than older versions too.
Timings extracting attributes from a 16 million vertex grid (seconds):
- Corner float attribute: 0.72 -> 0.19
- Face float attribute: 0.60 -> 0.07
- UV map: 3.18 -> 0.05
Implements #95967.
Currently the `MPoly` struct is 12 bytes, and stores the index of a
face's first corner and the number of corners/verts/edges. Polygons
and corners are always created in order by Blender, meaning each
face's corners will be after the previous face's corners. We can take
advantage of this fact and eliminate the redundancy in mesh face
storage by only storing a single integer corner offset for each face.
The size of the face is then encoded by the offset of the next face.
The size of a single integer is 4 bytes, so this reduces memory
usage by 3 times.
The same method is used for `CurvesGeometry`, so Blender already has
an abstraction to simplify using these offsets called `OffsetIndices`.
This class is used to easily retrieve a range of corner indices for
each face. This also gives the opportunity for sharing some logic with
curves.
Another benefit of the change is that the offsets and sizes stored in
`MPoly` can no longer disagree with each other. Storing faces in the
order of their corners can simplify some code too.
Face/polygon variables now use the `IndexRange` type, which comes with
quite a few utilities that can simplify code.
Some:
- The offset integer array has to be one longer than the face count to
avoid a branch for every face, which means the data is no longer part
of the mesh's `CustomData`.
- We lose the ability to "reference" an original mesh's offset array
until more reusable CoW from #104478 is committed. That will be added
in a separate commit.
- Since they aren't part of `CustomData`, poly offsets often have to be
copied manually.
- To simplify using `OffsetIndices` in many places, some functions and
structs in headers were moved to only compile in C++.
- All meshes created by Blender use the same order for faces and face
corners, but just in case, meshes with mismatched order are fixed by
versioning code.
- `MeshPolygon.totloop` is no longer editable in RNA. This API break is
necessary here unfortunately. It should be worth it in 3.6, since
that's the best way to allow loading meshes from 4.0, which is
important for an LTS version.

This patch refactors the texture samples code by mainly splitting the
eGPUSamplerState enum into multiple smaller enums and packing them
inside a GPUSamplerState struct. This was done because many members of
the enum were mutually exclusive, which was worked around during setting
up the samplers in the various backends, and additionally made the API
confusing, like the GPU_texture_wrap_mode function, which had two
mutually exclusive parameters.
The new structure also improved and clarified the backend sampler cache,
reducing the cache size from 514 samplers to just 130 samplers, which
also slightly improved the initialization time. Further, the
GPU_SAMPLER_MAX signal value was naturally incorporated into the
structure using the GPU_SAMPLER_STATE_TYPE_INTERNAL type.
The only expected functional change is in the realtime compositor, which
now supports per-axis repetition control, utilizing new API functions
for that purpose.
This patch is loosely based on an older patch D14366 by Ethan Hall.

The renderdoc integration used to be behind the `--debug-gpu`
command line option. When using `--debug-gpu` outside renderdoc
error messages where displayed that aren't relevant.
This PR adds a specific command line option for the renderdoc
integration. This option will also enable `--debug-gpu`.

Logic for the recently included fractional scaling support [0] was
difficult to reason about as it depended on two different callbacks
one that listened to a preferred scale, another that tracked which
physical displays the window overlapped.
Checking if fractional scaling was in used depended on the order
the callbacks ran - which is undefined.
In practice - mixing non-fractional and fractional displays would
flicker when the window was moved between monitors.
Resolve this problem with the following changes:
- When the fractional-scale manager is supported,
only respond to the scale from it's preferred_scale callback.
- When no fractional-scale manager is available,
set the scale based on the scale of overlapping outputs.
- Add support for postponing the buffers commit call to prevent
flickering when changing the windows scale.
Other changes:
- Use a lock before setting the pending frame state from
wp_fractional_scale_handle_preferred_scale.
- Ensure pending actions that themselves trigger pending actions
run in the time gwl_window_pending_actions_handle is called.
- Rename GWL_Window::scale -> GWL_WindowFrame::buffer_scale.

Depend on fractional-scale when searching for wayland-protocols
This will impact builders that don't use Blender's `../lib/` and
have wayland-protocols older than v1.31.
Make it a native Cycles light option instead of counter-acting the inverse
area calculation in Hydra.
