The operator went through quite a bit of trouble to pass a color
attribute index to the operator, but then it always used the offset
from the first layer of the active color attribute's type.
Also remove the "copy domains temp" API function, which
generalized this more than necessary, and exposed the internals
of the custom data system a bit more than we would like.
The two removed BKE functions were at a mid-level of abstraction
that doesn't make total sense in this API. Removing them is also
helpful in the general effort to have the attribute system rely less
on `CustomData` internally.
This simplifies the usage of the API and is preparation for #104478.
The `CustomData_add_layer` and `CustomData_add_layer_named` now have corresponding
`*_with_data` functions that should be used when creating the layer from existing data.

This changes the Switch node so that it is implemented directly as a lazy-function,
instead of as a normal geometry node which uses `GeoNodeExecParams`. This improves
the design of the layered execution api, where different nodes can be implemented
at a proper different abstraction level. The simplest kinds of nodes are implemented
as multi-function, then there is `GeoNodeExecParams` and more specialized nodes are
implemented as lazy-function. The switch node is special in the sense that it currently
needs extra behavior in the lazy-function graph generation anyway.
`GeoNodeExecParams` can be simplified as well, because the Switch node was the only
one that used the `lazy_` methods.
We could consider adding back lazy-input functionality to normal geometry nodes
as it becomes necessary. Ideally, that could be integrated with the node declaration.

Now only dynamic function parameters that use ParameterDynAlloc support
dynamically sized parameters arrays.
Add tests for both dynamic arrays that don't support resizing
(Image.pixels) and dynamic sized arguments using
(VertexGroup.add(index=[..])).
Regression in [0] which extended support for dynamic sized function
arguments.

This adds a new set of APIs supporting the loading and saving of image
formats through OIIO. It makes use of the recent IOProxy work in OIIO
to align with the existing Blender image loading/saving machinery.
The support code here has been prototyped to work with ~7 of our image
formats so far. It includes centralized handling of `IB_test`,
`IB_mem`, and `IB_metadata` flags, which the existing code did not
handle consistently or at all depending on the format.
The PSD format (`format_psd.cc`) is included since the prior location
of the code has been restructured away. It serves as an example of how
the loading code typically flows for all the other formats.

- DriverVariable.name update function passed DriverVar to
BKE_driver_invalidate_expression as a ChannelDriver.
- DriverTarget.name update function passed DriverTarget to
BKE_driver_invalidate_expression as a ChannelDriver.
- DriverVariable.type update function DriverVar accessed ChannelDriver,
clearing a flag.
This was exposed by [0] however this issue existed beforehand.

In practice this probably didn't cause bugs, but it would have
caused extra copies of the UV helper layers. The layers are only
needed if we find true values. Mistake in 0fe0db63d7.
This is a non-recent regression that strangely went unreported.
It is expected that when snapping, only visible elements are considered
which does not include faces in wireframe mode.
This works like this before, and this change doesn't appear to have
been intentional.
Ref #105664
One of the advantages of separating this enum member from the others is
because mixing several members in a single one hinders debugging since
in this case the IDE does not define which enums were set.
Also separating this item makes it more readable as `SCE_SNAP_MODE_GEOM`
is not a snap mode but a combination of modes.
VKPixelBuffer is used by external render engines to allocate buffers
using the same GPU backend that Blender runs in.
In a later stage we should test what exact binding flags are needed. I
expect that it should be able to use as a transfer buffer to copy the
pixels over to a texture using transfer commands.

This add the`CurvesGeometry::blend_read` and `CurvesGeometry::blend_write` methods
and uses them in the `curves_blend_read_data` and `curves_blend_write` functions.
No functional changes.

In most places where it appears in a menu, the operator would already
apply to all selected F-Curves. Now it is done consistently and explicitly
from all menu items. The default of the operator is now also set to 'all
selected', so that it also behaves like that when called from the operator
search menu.
The BMesh to Mesh conversion does some checks to the UV helper
attributes like selection to avoid copying them to the mesh if they
don't contain any meaningful data. However, it does this by looping
over all faces for every UV map, not in parallel, so it takes up a large
portion of the total time in the conversion. This commit moves that
to the existing similar checks.
On a 1 million face mesh with 3 UV maps, for me this improved the
conversion runtime by 75%, from 174ms to 99ms. Before the serial
loops took 88ms out of the total. Combining them with the existing
loop over faces only increased its runtime from 29 to 40ms.
The _gpu_ prefix is redundant as they are inside a namespace
and run as part of a test suite that already contain the name
gpu. (GPUOpenGLTest)
This patch also moved the texture test cases to its own
compile module.
When a shader is bound it should outlife the pipeline. In one
test case where only the shader data was accessed it also bound
the shader. This isn't needed as the shader data should be
retrieved without binding the shader.
This change fixes the issue by not binding the GPU shader.
Patch version was increased, but the file subversion should have
been increased.
Also fixes previous incorrect patch versioning code as it didn't
add all 'version code until next subversion bump goes here.' after
version bump.
The function set bits in a bitmap for all the edge indices in a face.
With future changes to mesh topology storage though, this level
of abstraction won't be as helpful anyway.
Refactoring mesh code, it has become clear that local cleanups and
simplifications are limited by the need to keep a C public API for
mesh functions. This change makes code more obvious and makes further
refactoring much easier.
- Add a new `BKE_mesh.hh` header for a C++ only mesh API
- Introduce a new `blender::bke::mesh` namespace, documented here:
https://wiki.blender.org/wiki/Source/Objects/Mesh#Namespaces
- Move some functions to the new namespace, cleaning up their arguments
- Move code to `Array` and `float3` where necessary to use the new API
- Define existing inline mesh data access functions to the new header
- Keep some C API functions where necessary because of RNA
- Move all C++ files to use the new header, which includes the old one
In the future it may make sense to split up `BKE_mesh.hh` more, but for
now keeping the same name as the existing header keeps things simple.

This is very similar to ebe8f8ce71, but applies the same
changes to conversions to non-evaluated meshes meant for original
data. The function also handles shape keys, UVs, selection history,
"scan the database" object vertex index remapping, and multires fixes.
Those operations are handled in parallel with the other conversions now.
Similar to before, the improvement is better the more attributes/data
contained in the BMesh. This time I observed an improvement of 50%
(182ms to 123ms) for a large grid mesh with many attributes, and 20%
for a large grid mesh with less data. Shape keys, selection, hiding, and
multires data should have less of a detriment to performance now too.
One remaining thing to improve is the recently added UV selection/pin
handling. This should be moved into the first single-threaded loop over
faces, or changed further.

- The Math node lost the headers of its operation type menu in
ee985fa925 , because a translation context was assigned to the RNA
property, but the headers declaration was not updated to extract the
messages with matching contexts.
- The message "Group Input" had a trailing space, which can be added
after translation.
This is something we missed in #104599.
Without it, the default color isn't always set.
Thanks to user roman-13 for pointing out the problem,
and thanks to Hans Goudey for telling me the solution.
