The issue is caused by the combination of the following factors:
- There is a driver from custom property to the subdivision surface
modifier.
- Active material index tags the ID for the copy-on-write update.
Dependency graph currently does not fully distinguish between
copy-on-write tag and properties-update tag, so the copy-on-write tag
makes the dependency graph believe that it is property which actually
affects evaluation has been changed.
The simple solution is to treat the active material slot index as an
interface data which does not need to trigger copy-on-write tag.
The possible downside of this solution is that if someone has a driver
from this property the driver will stop working. Whether there is such
a real-life setup or not is not clear. Is not something advisable to do
anyway.
Possible alternative would be to introduce more granularity into the
way how property tagging is done. This is something that would be nice
to implement eventually, but it is a much bigger refactor.

Basically copy the information from the commit message of the
03e2f11d48 directly to the code.
This makes the information easier to find when working on the
code.
The copy-on-write is really an implementation detail of the
dependency graph. While there are still cases where there is
no better tag to be used, the ID_RECALC_COPY_ON_WRITE should
not be used in combination with a dedicated tag.
For example if location of object changes the proper tag is
`ID_RECALC_TRANSFORM`. Tagging with `ID_RECALC_TRANSFORM |
ID_RECALC_COPY_ON_WRITE` will seemingly work, but this is
not an intended usage.
Ensure VolumeUniformPool uses is always incremented when retrieving a buffer in alloc().
Otherwise the same buffer will be retrieved for more than one object when incrementing the pool size.

If the compositor is enabled or disabled, the node warnings for
unsupported nodes is not updated because of a missing redraw. This patch
adds that missing redraw in order to make the change immediate.
Missed in the first commit[1].
Initially it was reported that the `flags` parameter was unused on
`imb_cache_filename` but it turns out another swath of code was unused
related to that same function. Clean this up now too.

The wrong guiding distribution was used when direct and indirect light
scattering happened at different locations. Now use a different distribution
for each location.
Recording is not quite correct since OpenPGL does not support spliting the
path like this, instead recording at the start of the volume ray. In practice
this seems to make little difference.

Swapping some ID lists between Mains must invalidate the name_map cache.
Note that in theory, at least WM type could be ignored by name_map
cache, since it is a singleton. However, don't think it's worth adding
extra complication here, for really marginal benefits. The overhead of
rebuilding the name cache here is extremly small.
For some reason, this issue did not show so far in master, only appeared
in some branch work on improving (in)direct status of linked IDs... Go
figure.
With this change Blender, delivered via the Microsoft store, will launch without the console window flashing.

Previously when using the "Jump To Keyframe" operator
in conjunction with subframes, the decimal part would be kept.
Meaning that it wouldn't jump exactly to the frame.
This fix also makes it so it is possible to jump to keyframes
that are on subframes.

This removes the unused code for the IBM tile cache APIs. These have
been unused for as far back as I could manage to search.
Since TIFF was used for the cached images, this removal will allow for
an easier review when it comes time to move TIFF to OIIO as part of
T101413.

When either initializing with a non-constant value, or using the standard
[[ string widget = "null" ]] metadata. This can be used for inputs like
normals and texture coordinates, where you don't want to default to a
constant value.
In previous OSL versions the input value was automatically ignore when it
was left unchanged for such inputs. However that's no longer the case in
the latest version, breaking existing nodes. There is no good entirely
backwards compatible fix, but I believe the new behavior is better and will
keep most existing cases working.

a5e7657cee didn't account for slices of zero sizes, and the asserts
were slightly incorrect otherwise. Also, the change didn't apply to
`Span`, only `MutableSpan`, which was a mistake. This also adds "safe"
methods to `IndexMask`, and switches function calls where necessary.
