The "reverse map" of corners to faces and points to curves is the same
for meshes and curves now. Move it to the offset indices header to
reflect this.
This unification can go further in the future, but I'd rather wait
until the design is clearer for now.
Pull Request: blender/blender#106570
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.

`PLATFORM_BUNDLED_LIBRARIES` was installing right next to the blender
executable rather than the `blender.shared` folder,
`PLATFORM_BUNDLED_LIBRARIES` wasn't used very much on windows, just
by the ONEAPI code which likely wasn't aware this plumbing was
still missing.
This diff adds support for using `PLATFORM_BUNDLED_LIBRARIES` on
windows in both debug and release configurations.
You can differentiate between a .dll being installed for debug/release
or all configurations, by prefixing the library with either `DEBUG`,
`RELEASE` or `All`, if no prefix is given `ALL` is assumed.

When accessing UVmaps from python in BMesh, the UVmap name/index was ignored
and the active UVmap always used. This fixes this by passing the layer index
to the underlying CustomData function.
Pull Request: blender/blender#106537
This was only used in a single place, multires baking, where it's simple
to just retrieve the looptris from the temporary `Mesh` that we already
create to simplify accessing normals. This allows removing a bunch of
complexity from `DerivedMesh`, to help progress towards its complete
removal at some point in the future.
Also use `Span` more instead of raw pointers in multires baking,
and pass around the spans instead of the low-resolution DerivedMesh.
Caused by 16fbadde36. The first mistake was passing a pointer
to a poly to what was meant to be the pointer to the start of the array.
Use Span instead to avoid that confusion. The second was a logic error
in CCGDerivedMesh's lazy initialization of corner data. The data was
copied when the mesh is created so it wasn't initialized.
This PR adds debug information inside the spir-v assembly to enable
step-by-step debugging of Shaders using renderdoc. The debugging
information can be fairly large so are only generated when used
with the `--debug-gpu-renderdoc` feature.
During debugging shader optimizations are turned off.

Regression caused by 98bfa8d458
The `XRAY_ENABLED(v3d)` check was lost during a modification to
`transform_snap_context_project_view3d_mixed_impl` function.
This caused vertex snapping in solid shading to jump between visible
and occluded faces.

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.

Related to #106535 where a similar fix was done for OpenGL. A small
cleanup that might reduce the complexity during GLSL shader compilation.
Pull Request: blender/blender#106538
Renderdoc requires all calls/updates to originate from the same
context. It also doesn't support multithreading. For now we
enable main context workaround.
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`.

This was the case with hidden faces and `Sync Selection` turned ON.
Caused by 8f543a73ab.
Since 8f543a73ab, the UV element map
respects the hidden state of geometry, but stitching [which also
respected this on its own even prior to the culprit commit in its
calculation of connectivity] did this differently [it only skipped
hidden geo when UV_SYNC_SELECTION was OFF -- even though UVs would not
be visible which is probably the real error here, I believe there is
this principle that we "dont act on stuff we dont see"].
To fix this, also skip hidden geo (even with UV_SYNC_SELECTION = ON) in
the stitch calculation of connectivity, just as
`BM_uv_element_map_create` does it.
Should go into 3.3 LTS as well.

This happens even though there is only one user.
The Outliner only implements this `Make Single User` for worlds
(`singleuser_world_fn`) and actions (`singleuser_action_fn`) [it is
questionable if the whole functionality could be removed really, but
this is for another report] and it uses `id_single_user` to do so --
this function does not check if we even have more than one user though,
so data gets duplicated resulting in duplicate worlds or actions even if
they only have one user and shouldnt be touched.
Now let `id_single_user` check usercount and only act if we have more
than one real users.
Pull Request: blender/blender#105991
Caused by filebrowser calling space `refresh` function. The intention of
refresh function was mainly to hide channels when view type is changed.
Unhiding channels when view is changed back seems logical, but this
causes issues when region is too thin, which results in hiding side
panel, which is more important.
When creating nodes by dragging a link, it can be convenient to
transfer values from input socket. For reference values, like images,
this may be necessary to avoid unnecessary data-block users. This
patch starts adding such a system. At this moment this only makes sense
for one node (Image Input), but this can be extended to work with other
reference types, different non-reference types and support auto-casting
(if a float is transferred to the Integer Input node).

The potential optimization in the normal edit modifier when flipping
faces isn't worth the "API impurity" and complexity introduced by
adding poly normal editing as part of the API. This change simplifies
future changes to the ownership of poly normals with a shared cache,
which can prevent recomputing poly normals completely.
Vertex positions and faces aren't changed, so most caches shouldn't
need to be tagged. This removes unnecessary re-computation of bounds,
triangulation, loose edges, etc.

Use raw Blender structs and mesh data rather than using the RNA API.
There isn't any benefit from using the RNA when Cycles is compiled
with Blender anyway, and a profile showed that the majority of time
was spent in Blender RNA API functions.
This gives a significant improvement in performance when ingesting
meshes. Here are some tests of the runtime of the `create_mesh`
function (in seconds):
| | Before | After |
| ------------------------- | ------ | ----- |
| Grid | 0.66 | 0.11 |
| Many realized cubes | 2.60 | 0.48 |
| Large curve to mesh setup | 4.18 | 1.14 |
Also change to resizing the arrays and filling them by index rather
than appending. This makes the parallel aspect of the logic clearer,
and makes the loops easier to parallelize in the future, and makes
it easier to have a performance benefit when an attribute like
`sharp_face` doesn't exist.

No functional changes.
Edges hidden by Optimal Display are hidden by edge factor Shader.
But there is not much advantage in doing this, as the number of edges
hidden by the Optimal Display is usually much higher than the number of
visible edges.
And the lines extractor does not include invisible edges due to other
factors.
So this change makes:
- Visibility test more consistent with what is actually seen.
- Smaller buffer for IBO sent to GPU
- consistency with GPU Subdivision that already considers Optimal Display
- Allows possible improvement in the "Edge Factor" extraction by making
it unnecessary to check the Optimal Display (except for optimization).

Popover menu buttons had their labels translated but not their
descriptions, although they were properly extracted.
This commit fixes that using the `TIP_()` macro.
This information is displayed in the top left of the 3D Viewport with
other text info. The units of the grid are already extracted, but they
were not translated in the drawing code.
Remove comments from `eBConstraint_Types` that
- were used long ago during a big refactor effort, but are no longer
necessary, or
- just repeated the name of the enum constant.
No functional changes.
OpenEXR has some dependecies that other other modules in Blender

Splitting workload dependency chains such that they
only exist within the context of a single frame.
Dependencies are required to ensure sequential
command buffer submissions execute in order,
but the additional dependencies between frames
could incur GPU timeouts, if a signal was delayed.
This could be triggered by both CPU/GPU cycles
texture updates and Viewport Compositor operations.

Very sadge to see this kind of mistakes still exist in 2023 code...
While in theory this commit could be backported to (LTS) releases, would
rather only do it if/when proven it actually fixes user-facing issues.
Fixing such issues so deep in ID management code can have completely
unexpected side effects.
The framebuffer default size was only set during the first bind. This
is because the `dirty_attachments_ tag` wasn't set and thus the
framebuffer size was never passed down to the GL.
Split to `default_size_set()` to not affect other code paths that use
`size_set()`.
Adds the ability to pack UVs back into the original bounding box.
