For a 16 million vertex mesh, when there are no loose vertices or edges,
copying that information to new original mesh saves 100ms after applying
a modifier on a Ryzen 7950X.
This was only used in one place. Adding the name lookup to
`SCULPT_vertex_mask_get` is not good long term, but the use
of that function can be removed too.
Store paint masks as generic float attributes, with the name
`".sculpt_mask"`. This is similar to 060a534141, which made
the same change for face sets. The benefits are general
consistency, nicer code, and more support in newer areas
that deal with attributes like geometry nodes.
The RNA API is replaced with one created in Python. The new
API only presents a single layer as an attribute class, so it
should be simpler to use in general:
- Before: `object.data.vertex_paint_masks[0].data[0].value`
- After: `object.data.vertex_paint_mask.data[0].value`

Multi indirect drawing would bind an offset index buffer, but
indirect drawing parameters also offset the index buffer so
incorrect geometry was drawn.
Fixes drawing of meshes with multiple materials.

Snap to geometry is not supported when moving camera in camera view.
This is because the camera would make jumps that would be difficult to
predict and control.
The same happens if Snap Base were supported.
Therefore, disable Edit Snap Base when transforming camera into camera
view.
"Solidify" modifier in "Complex" mode was creating redundant layer
"bevel_weight_edge.001", if mesh has bevel weights for vertex set.
All modifier's custom edge bevel weight calculations went there and got lost.

This PR shows the memory footprint in the statusbar when activated.
Only memory allocated on the VRAM is counted. Memory allocated on host

Since above commit, the edge crease is a named attribute and considered
a "fake" customdata layer (similar to bevel weights or UV seams --
`CD_FAKE`). Thus, a special case in
`data_transfer_layersmapping_generate` has to be added for
`CD_FAKE_CREASE`.

The buffers from the new Draw Manager increase their size as needed,
but they never shrink.
Add `StorageArrayBuffer::trim_to_next_power_of_2` function that can
downsize the buffer following the same heuristic as `get_or_resize`.
Add `StorageVectorBuffer::trim_and_clear`, which calls
`trim_to_next_power_of_2` automatically.

Modify `UVStretchAngle` vertex struct alignment to match
4-byte struct alignment for Metal. This includes reordering
array elements to the front and adding additional padding
to the struct in Metal such that the raw-data write size
matches the padded vertex format.

The meta strip range was calculated before the effect strip range was
updated. This resulted in incorrect range. To the user this appeared
as the meta strip erratically jumping to another location in the
timeline when transforming it, when it contained effect strips.

Avoid the need to call the separate `BKE_mesh_wrapper_minmax` function
that dealt with the edit mesh wrapper. This makes the API inconsistent,
since other mesh functions don't implicitly deal with the wrapper.
But the bounds are a bit of a special case anyway in regard
to the GPU subdivision wrapper already, and this is much more
convenient in the rest of the refactors for #96968.
Use functions to retrieve the next and previous corners
in a face. The complexity of tracking them manually isn't
worth it here. Also standardize naming a bit and use a
C++ BitVector instead of the C equivalent.

There was a C++ STL importer since Blender 3.3, but no corresponding C++ STL exporter. This PR is adding said exporter: taking https://projects.blender.org/blender/blender/pulls/105598 and finishing it (agreed with original author).
Exporting Suzanne with 6 level subdivision (4 million triangles), on Apple M1 Max:
- Binary: python exporter 7.8 sec -> C++ exporter 0.9 sec.
- Ascii: python exporter 13.1 sec -> C++ exporter 4.5 sec.

This struct is currently defined in the `functions` module but not actually used there. It's only used by the geometry nodes module, with an indirect dependency from blenkernel via simulation zone baking. This scope is problematic when adding grids as socket data, which should not be part of the functions module.
The `ValueOrField` struct is now moved to blenkernel, so it can be more easily extended to other kinds of data that might be passed around by geometry nodes sockets in future. No functional changes.

This path merges the Musgrave and Noise Texture nodes into a single
combined Noise Texture node. The reasoning is that both nodes
intrinsically do the same thing, which is the layering of Perlin noise
derivatives to produce fractal noise. So the patch de-duplicates code
and unifies the use of fractal noise for the end use.
Since the Noise node had a Distortion input and a Color output, while
the Musgrave node did not, those are now available to the Musgrave types
as new functionalities.
The Dimension input of the Musgrave node is analogous to the Roughness
input of the Noise node, so both inputs were unified to follow the same
behavior of the Roughness input, which is arguable more intuitive to
control. Similarly, the Detail input was slightly different across both
nodes, since the Noise node evaluated one extra layer of noise. This was
also unified to follow the behavior of the Noise node.
The patch, coincidentally fixes an unreported bug causing repeated
output for certain noise types and another floating precision bug
#112180.
The versioning code implemented with this patch ensures backward
compatibility for both the Musgrave and Noise Texture nodes. When
opening older Blender files in Blender 4.1 the output of both nodes are
guaranteed to always be exactly identical to that of Blender files
created before the nodes were merged in all cases.
Forward compatibility with Blender 4.0 is implemented by #114236.
Forward compatibility with Blender 3.6 LTS is implemented by #115015.

This changes a bunch of nodes that have a data type drop-down to using a dynamic
node declaration that changes based on the selected data type instead of always having
all sockets. This greatly simplifies the code and is less weird than having suffixes on
socket identifiers.
Backward compatibility and forward compatibility remain due to #113497 and #113984.
One user-visible change is that changing the data type in these nodes does not break
the link anymore.
It may be necessary to bring back some functionality from link-drag-search afterwards.
