This patch adds initial support for compute shaders to
the vulkan backend. As the development is oriented to the test-
cases we have the implementation is limited to what is used there.
It has been validated that with this patch that the following test
cases are running as expected
- `GPUVulkanTest.gpu_shader_compute_vbo`
- `GPUVulkanTest.gpu_shader_compute_ibo`
- `GPUVulkanTest.gpu_shader_compute_ssbo`
- `GPUVulkanTest.gpu_storage_buffer_create_update_read`
- `GPUVulkanTest.gpu_shader_compute_2d`
This patch includes:
- Allocating VkBuffer on device.
- Uploading data from CPU to VkBuffer.
- Binding VkBuffer as SSBO to a compute shader.
- Execute compute shader and altering VkBuffer.
- Download the VkBuffer to CPU ram.
- Validate that it worked.
- Use device only vertex buffer as SSBO
- Use device only index buffer as SSBO
- Use device only image buffers
GHOST API has been changed as the original design was created before
we even had support for compute shaders in blender. The function
`GHOST_getVulkanBackbuffer` has been separated to retrieve the command
buffer without a backbuffer (`GHOST_getVulkanCommandBuffer`). In order
to do correct command buffer processing we needed access to the queue
owned by GHOST. This is returned as part of the `GHOST_getVulkanHandles`
function.
Open topics (not considered part of this patch)
- Memory barriers & command buffer encoding
- Indirect compute dispatching
- Rest of the test cases
- Data conversions when requested data format is different than on device.
- GPUVulkanTest.gpu_shader_compute_1d is supported on AMD devices.
NVIDIA doesn't seem to support 1d textures.

Alternatively this could use `ASSET_LIBRARY_ALL` like
`add_node_search.cc`, but then it would need a different
method for skipping duplicate local assets.
Mandatory change for the Brush Assets project, from quick test does not
seem to break anything (more) in existing 'old' brushes...

This adds support for cursor snapping for the new curves object.
It implements a function `transverts_from_curves_positions_create` (to separate the logic from the `Curves` object type). That function is then C wrapped by `ED_curves_transverts_create` and finally used in `ED_transverts_create_from_obedit`.
Pull Request #104967
Fixes the `-Winconsistent-missing-override` warning.
In theory the `virtual` is redundant in such case, but this is how
it is done in may other areas of USD code.
Pull Request #104977
Previously when markers were used, the newly introduced clamping code (#104516) would stop the last channel from being shown.
This patch fixes that by modifying the `v2d->tot.ymin` calculation.
This is a bit counterintuitive since the `v2d->tot` height is calculated in `action_draw.c`. But the advantage of doing it there is that it also works for the channels region.
Pull Request #104892
Added new function sculpt_mesh_filter_cancel in sculpt_filter_mesh.cc
for cancelling mesh filters. It currently is unused pending a
revamped modal map for mesh filter (see pull req 104718).
In the outliner, the icons for modifiers are tinted blue. This didn't
work for the geometry nodes modifier icon.
Defining the icon with the macro `DEF_ICON_MODIFIER` also
defines the appropriate theme color so it's now tinted blue
when drawn in the outliner like the other modifier icons.
Pull Request #104957
Add a per node type callback for creating node add search operations,
similar to the way link drag search is implemented (11be151d58).
Currently the searchable strings have to be separate items in the list.
In a separate step, we can look into adding invisible searchable text
to search items if that's still necessary.

Add `BLI_change_working_dir(path)` to change the current working directory.
This change is required for adding USDZ support to Blender. When exporting to that format, we are required to do a weird change of directory because of a quirk with the USD library's USDZ functionality. If an absolute filepath is passed into the `UsdUtilsCreateNewUsdzPackage` function, the USDZ archive will store that full path.
macOS uses `NSFileManager` through some new Mac-only wrapper functions.

The check was triggering the 'this' pointer cannot be null in
well-defined C++ code
We do not check for this pointer in any other areas. If it is
needed due to possible opaque pointer cast to the check prior
to the cast.

That way the `matrix_base` doesn't need to depend on the axis
simplifying the code.
This also fixes an issue in plane scaling gizmos with non-orthogonal
matrix.
After rBdb87e2a638f9, two contexts were missing:
- VirtualReality, to be used in an add-on
- Constraint, used in the constraints UI
The latter was actually used without being added, which caused errors.
It was reverted in rB31a640027982.
The operator's description used a format string like:
```
BLI_sprintfN(TIP_("%s %s vertex groups of the active object"),
action_str, target_str)
```
which is almost guaranteed to be impossible to properly localize to
some languages -- I know there are a couple of issues for French
already.
So instead of hoping formatting works, write all possible strings
explicitly, even if it looks stupidly verbose.
Simplify modifier sample mode didn't transfer UV parameters, now fixed.
(This is the corrected commit, previous one has multiple other commits merged.)
Pull Request #104964
This reverts commit 19222627c6.
Something went wrong here, seems like this commit merged the main branch
into the release branch, which should never be done.
Currently Metal is more stable then the OpenGL backend on apple
devices. Also the Metal backend supports more features then the
OpenGL backend. For example the viewport compositor and rendering
of production files.
This has been validated with users and studios.
This patch will default to the Metal backend when starting
Blender 3.5 for the first time or when loading factory startup. It
is still possible to switch to OpenGL via the user preferences.
It will not automatically select the Metal backend when there is
already user preferences available for Blender 3.5.
This is a missing part of the Metal backend. Metal backend doesn't
support the bgl commands, but it was not possible to use the gpu
module to use scissor testing.
Without this change addon developers would not be able to migrate
their addons to support the Metal backend.
This patch adds:
- `gpu.state.scissor_set`
- `gpu.state.scissor_get`
- `gpu.state.scissor_test_set`
Fix#104911
Texture clamping is by default off, but for VDM textures this leads
to several artifacts.
- Clamping is done when the image is sampled and when the brush strenght
is applied.
- VDM textures have negative values that are lost due to clamping
when clamping during sampling.
This patch fixes this by changing the default clamping of newly
created textures to not clamp anymore.
Textures are mostly being used by sculpt brushes, where clamping is also
implemented on brush level.
Fix#104747
Regression in [0] which caused interacting with 2D gizmos not to
update 3D gizmos once the gizmo finished it's modal interaction.
This caused the cameras lens gizmo not to update when navigating using
the viewport navigation buttons.
Resolve by detecting this case and flagging other draw steps to be
updated.

In the first loop is safe to remove the current element.
The second loop can remove any element, potentially the next.
This triggers a read after freed.
Pull Request #104897
When the new UV to legacy format conversion happens, the mesh is in
the middle of being written and is an at best "complicated", at worst
invalid state. The attribute API looks at other domains and is a bit
less forgiving in that respect, and shouldn't really be used here. Use
the CustomData API instead. Also sort the layers the same way as
b642dc7bc7.
