It was never added for the field on domain and field at index nodes.
They need special handling because they have many what should be
a multi-type socket declaration.
This patch adds a `mute` RNA property on `ActionGroup`s that allows them to be easily muted/unmuted from python.
This uses the existing `AGRP_MUTED` flag which was also accessible from the user interface.

Previously there was a special extraction process for "vertex colors"
that copied the color data to the GPU with a special format. Instead,
this patch replaces this with use of the generic attribute extraction.
This reduces the number of code paths, allowing easier optimization
in the future.
To make it possible to use the generic extraction system for attributes
but also assign aliases for use by shaders, some changes are necessary.
First, the GPU material attribute can now store whether it actually refers
to the default color attribute, rather than a specific name. This replaces
the hack to use `CD_MCOL` in the color attribute shader node. Second,
the extraction code checks the names against the default and active
names and assigns aliases if the request corresponds to a special active
attribute. Finally, support for byte color attributes was added to the
generic attribute extraction.

Changing the value doesn't accomplish anything, since the retrieved
value would be the same for every index then. So it's best to hide it
to make the node clearer.
The Graph, Driver, and Dopesheet's (and sub modes) properties panel
(N-Panel) are now open by default. This includes the editors in the
default Animation workspace.
Note that, because the Timeline is implemented as a special mode of the
Dopesheet, switching between Timeline and Dopesheet will *not* change
the visibility of the properties panel.

`parallel_invoke` allows executing functions on separate threads.
However, creating tasks in tbb has a measurable amount of overhead.
Therefore, it can be benefitial to disable parallelization when
the amount of work done per function is small.
See D15539 for some benchmark results.

The stroke points were changed but the bounding box calculation was not done and this produced a problem in any bounding box check done by different tools.
Any script that raised a SystemExit called by --python, --python-expr
command line args or by executing the text block would exit without
printing a message. This caused the error from T99966 to be hidden.
Add explicit handling for SystemExit to ensure the message is always
shown before exiting.
More details noted in code-comments.
There is a 1 pixel error in the size registered for the buffer
dimensions.
NOTE: This issue indicates that the texture scale is different from the
region, so the mouse-based coordinates used are actually misaligned.
This misalignment will be fixed in another commit.

The "snap to surface" operators now have "disabled" poll messages
when there is no surface object.
The implementation in most curves operators is also unified.
The goal is to avoid having to define and use the poll failure messages
in multiple places, to reduce the boilerplate that tends to be
necessary to add an operator, and to increase the likelihood that
operators are implemented with proper poll messages.

This fixes two issues:
* There was a crash when the new attribute name was empty.
* The attribute name was incremented (e.g. "Attribute.001") when
the old and new name were the same.
Proposed solution by @scurest The color attribute in the RNA was tagged as
COLOR_GAMMA. This change will change it to a regular COLOR.

It looked up the vertex group index based on the object instead of the
actual mesh that is currently used. Since geometry nodes, the number
and order of attributes can change in arbitrary ways during evaluation.
Therefore, this index has to be looked up on the mesh which contains
the most up-to-date information.
There are probably similar issues in other modifiers. That has to be
fixed step by step. Ideally by using the attribute api directly eventually.
When dragging assets into the 3D View while in any other mode than
object mode, dropping would be disabled and the cursor would indicate
that. However there was supposed to be an "Only supported in object
mode" message, that similar operators showed, but got forgotten when
this one was introduced.
UV maps that are used for surface attachment must not have overlapping
uv islands, because then the same uv coordinate would correspond to
multiple surface positions.

Calling two non-const methods on a `MutableAttributeAccessor`
at the same time in multiple threads is not safe.
While I don't know what caused the crash here exactly, I do know
that it happens while looking up the attribute for writing, which
may modify the unterlying geometry. I couldn't reproduce the
bug with a debug build or without threading.
When texture painting a lot of time is spent in ED_image_paint_tile_find.
This fixes stores the PaintTiles in a blender::Map making ED_image_paint_tile_find an O(1) rather than O(n) operation.
When using threading the locking should happen during read as well,
still this gives a boost in performance as the read is now much faster.

In a test producing 10 million vertices I observed a 3.6x improvement,
from 470ms to 130ms. The largest improvement comes from calculating
each mesh array on a separate thread. Besides that, the larger changes
come from splitting the filling of corner and face arrays, and
precalculating sines and cosines for each ring.
Using `parallel_invoke` does gives some overhead. On a small 32x16
input, the time went up from 51us to 74us. It could be disabled
for small outputs in the future. The reasoning for this parallelization
method instead of more standard data-size-based parallelism is that the
latter wouldn't be helpful except for very high resolution.
As discussed, this only updates objects in and the world of the scene to which the view layer belongs, which also avoids the problem of not having a BMain available.

The Alembic importer uses a linear search over the mesh edges to find
the right edge when setting edge creases. Although the complexity is
`O(m * n)`, with `m` being the number of creased edges, and `n` being
the number of edges, this can lead to a quadratic complexity as `m`
approches `n`.
This patch uses `EdgeHash` to store and retrieve the edges, which
should bring complexity closer to `O(n)`, provided that lookup is
`O(1)`.
See differential for some timings. In most files, this is expected
to give at least a 2-3x speedup for this operation, but can lead
orders of magnitude speed increase for dense meshes with a significant
number of edge creases.

Use the C++ API to implement more of the existing C functions.
This corrects the cases where one tries to add a builtin attribute
with the wrong domain or type on curves, though a better warning
message would be helpful in the future, and also reduces duplication
of the internal logic. Not much more is possible without changing
the interface.
The display depth is used to composite Gpencil and Overlays. For it to
be stable we bias it using the dFdx gradient functions. This makes
overlays like edit mode not flicker.
The previous approach to save the 1st center sample does not work anymore
since we jitter the projection matrix in a looping pattern when scene
is updated. So the center depth is only (almost) valid 1/8th of the times.
The biasing technique, even if not perfect, does the job of being stable.
This has a few cons:
- it makes the geometry below the ground plane unlike workbench engine.
- it makes overlays render over geometry at larger depth discontinuities.
