The attribute, like the other attributes that start with `.` is not
supposed to be displayed in the spreadsheet or the attribute list
by default. This was missing from the commit that added the attribute.
Currently the shade smooth status for mesh faces is stored as part of
`MPoly::flag`. As described in #95967, this moves that information
to a separate boolean attribute. It also flips its status, so the
attribute is now called `sharp_face`, which mirrors the existing
`sharp_edge` attribute. The attribute doesn't need to be allocated
when all faces are smooth. Forward compatibility is kept until
4.0 like the other mesh refactors.
This will reduce memory bandwidth requirements for some operations,
since the array of booleans uses 12 times less memory than `MPoly`.
It also allows faces to be stored more efficiently in the future, since
the flag is now unused. It's also possible to use generic functions to
process the values. For example, finding whether there is a sharp face
is just `sharp_faces.contains(true)`.
The `shade_smooth` attribute is no longer accessible with geometry nodes.
Since there were dedicated accessor nodes for that data, that shouldn't
be a problem. That's difficult to version automatically since the named
attribute nodes could be used in arbitrary combinations.
**Implementation notes:**
- The attribute and array variables in the code use the `sharp_faces`
term, to be consistent with the user-facing "sharp faces" wording,
and to avoid requiring many renames when #101689 is implemented.
- Cycles now accesses smooth face status with the generic attribute,
to avoid overhead.
- Changing the zero-value from "smooth" to "flat" takes some care to
make sure defaults are the same.
- Versioning for the edge mode extrude node is particularly complex.
New nodes are added by versioning to propagate the attribute in its
old inverted state.
- A lot of access is still done through the `CustomData` API rather
than the attribute API because of a few functions. That can be
cleaned up easily in the future.
- In the future we would benefit from a way to store attributes as a
single value for when all faces are sharp.

Node tree updates can crash if the tree contains a node group that points at an "undefined" tree type.
This can happen if the tree is linked from a library and the path is lost,
or if a custom (python) tree is used and the script is not run.
The fix is to check if the node group type is valid ("registered") and return an empty list otherwise.

The first implementation based the max value on what seemed reasonable.
It was therefore limited it to 5.
I received a request from a user in the first already merged #104741
to allow a higher max value.
Thus I adjusted the max value to be the same as the max value used for
"Vertex Size", 32.

Render the transparent object bounds to a low-res frame-buffer and ray-march the
bounds volume, tagging shadow tiles along the way.
The bounds volume is inflated by half a pixel as a conservative rasterization
alternative, to ensure the tiles needed by all LOD0 pixels get tagged.
The bounds are rendered with front face culling and then the fragment shader
ray-marches against the bounds volume.
Each ray-marching step size equals the world space size of the pixel at the step
depth.
The step bounding sphere radius is also sent to the shadow usage tagging library
to ensure the whole step volume is tagged.

Hello, this is a small PR to check that my understanding of #102427 is correct before moving on to the rest of the issue.
This PR contains the updated UI of the `Sculpt` menu only. Other menus will be submitted for review later.
Currently exposed operators:
* Move
* Rotate
* Scale
* Box Trim (Trim Mode ="Difference")
* Lasso Trim (Trim Mode ="Difference")
* Box Add (Trim Mode ="Join")
* Lasso Add (Trim Mode ="Join")
* Line Project
* Smooth
* Surface Smooth
* ~~Scale (Could be left out?)~~
* Inflate
* Random
* Relax Topology
* Relax Face Set Boundaries
* Sharpen
* Enhance Details
* Erase Displacement
The original issue specifies `Relax Face Set Boundaries` and `Erase Displacement`. I'm not quite sure if this is done in the UI code or somewhere else.

Pick select is only meant to change a single element from a single
data-block. However, the operator worked on each object individually
rather than first finding the closest point, then processing the
selection. Change the operator to find the closest point across all
objects, then deselect if necessary, then select the closest point.

Previously `SEQ_transform_single_image_check` function was used to check
if image or effect strip has only one frame of content. Now these strips
are flagged with `SEQ_SINGLE_FRAME_CONTENT`.
While previously this was implicit property of strip, benefit of having
explicit flag is that this property can be decoupled from strip length.
At a random the bf_io_ply_tests would fail in one of the fixtures.
The root of the issue was that the exporter parameters were used
uninitialized, causing the mesh to be triangulated in some of the
runs and not be triangulated in other runs.
This change makes it so PLYExportParams is always zero-initialized,
so that this solves this issue, and that adding fields to it in the
future will not re-introduce the issue.

This patch implements the bicubic interpolation option in the transform
nodes. The path merely reuse the code in the shader image texture and
adds bicubic variants to the domain realization shader.
