Certain packed images, like those loaded directly into memory with
`BKE_image_packfiles_from_mem`, would cause USD to process the images as
"in memory" rather than as "packed" because the API was not removing the
IMG_GEN_TILE flag.
Additionally, be sure to use the packed filepath whenever possible
rather than the name given to the Image datablock as this ensures the
correct file names are used inside the USD file and for the resulting
file on disk after export.
This also fixes 2 render tests which now match when compared to the
native renders.

* Store scene linear to XYZ conversion matrix in each blend file, along
with the colorspace name. The matrix is the source of truth. The name
is currently only used for error logging about unknown color spaces.
* Add Working Space option in color management panel, to change the
working space for the entire blend file. Changing this will pop up
a dialog, with a default enabled option to convert all colors in
the blend file to the new working space. Note this is necessarily only
an approximation.
* Link and append automatically converts to the color space of the main
open blend file.
* There is builtin support for Rec.709, Rec.2020 and ACEScg working spaces,
in addition to the working space of custom OpenColorIO configs.
* Undo of working space for linked datablocks isn't quite correct when going
to a smaller gamut working space. This can be fixed by reloading the file
so the linked datablocks are reloaded.
Compatibility with blend files saved with a custom OpenColorIO config
is tricky, as we can not detect this.
* We assume that if the blend file has no information about the scene
linear color space, it is the default one from the active OCIO config.
And the same for any blend files linked or appended. This is effectively
the same behavior as before.
* Now that there is a warning when color spaces are missing, it is more
likely that a user will notice something is wrong and only save the
blend file with the correct config active.
* As no automatic working space conversion happens on file load, there is
an opportunity to correct things by changing the working space with
"Convert Colors" disabled. This can also be scripted for all blend files
in a project.

If any display, view or colorspace is not found, these would be changed to an
existing one and show warnings in the console. Now also warn about this in the
user interface using the same mechanism as loading new blend files in older Blender
versions, with a warning in the status bar and on file save.

Replaces current basis function calculation which seems to be a direct
implementation of the recursive NURBS formulation. New implementation
avoids the need to check for zero divisions during iteration. Out of
bounds checks are also converted to asserts, assuming input provides
valid span index.
Performance wise this nets a 7+% performance improvement with the
average result being as fast or faster then the fastest execution
from previous implementation!

Currently attribute names are often added to a hash map that doesn't
maintain the original order. This is convenient for developers but it's
better for users if attributes aren't arbitrarily reordered. Instead,
use `VectorSet` which gives the benefit of a hash map but maintains the
insertion order. The main downside is the loss of O(1) removal which we
benefited from in a few cases. I used string comparison instead for now.

When panels in node groups were introduced, the interface data of a tree was
moved from `tree.inputs_legacy/outputs_legacy` to `tree.tree_interface`. For
forward compatibility, the old interface was still written. Since Blender 4.5
can read the new format and older versions are not able to open files created in
5.0 directly anymore, it's fine to remove this forward-compatibility code now.
Also fixes#145278.

Like image saving, this may be modified from the scene ImageFormatData
to contain the effective color management settings taking into account
overrides.
For upcoming changes, we will need to know the image buffer colorspace when
starting to write the video instead of only on the first frame.

* Moves the paint cursor pointer to `PaintRuntime`
* Removed the stored runtime color value - this was effectively
hardcoded to a shade of red (255, 100, 100) with an alpha of 128.
The red color was only used for the smooth stroke overlay (the trailing
line) and the alpha value was only ever used for the *Line* stroke type.

This commit adds support for users to customize individual pressure
mapping curves for size, strength, and position jitter on a per-brush
basis to improve expression when using drawing tablets. This feature is
already implemented in Grease Pencil, and this PR adds the same
functionality to Texture/Image paint, Vertex/Weight paint, and Sculpt
modes.
The UI and functionality are the same as those in Grease Pencil.

Somehow the file in this report ended up with a node pointer that
disagreed with the socket pointer. Since we use the latter for drawing,
that's a better source of truth. This commit adds a versioning step
that corrects the node pointer. If this happens again we may need
to run the versioning again at some point, but that's not clear.

Add back custom properties to nodes, and properly expose them in the UI
as such (new 'Custom Properties' panel for nodes in the the Node
Editor).
This shows like any other custom property panel in the UI, in the Node editor:
<img width="424" alt="image.png" src="attachments/adb50815-0db0-447f-ac3b-7860d9a3e3fc">
Although not initially intended for this, nodes 'mixed' IDProperties
were quite widely used by py/extensions developers to store per-node
data.
During the initial IDProperties split between User-defined (aka custom
data) and system-defined (runtime RNA properties), this was not known,
so decision was made to only keep system properties for Nodes. The fact
that these properties were not exposed at all in UI also played a role
in that decision. See also discussions in #141042.
This commit instead splits system properties out into their own new
storage, and keep existing ones for user-defined/custom properties
(as done for other IDProperty owners, like IDs, bones, etc.).

This applies an OpenColorIO display, view and look transform on a color
in the scene_linear colorspace.
In general, OpenColorIO configurations do not contain a colorspace for
every view + display, especially if they are modern configs using the
display colorspace and shared view mechanisms. Nor do they include looks.
So the Convert Colorspace node is not sufficient.
Additionally, we would like to avoid making the colorspace list too long
in the default config, as we are adding many new views and transforms.
Exposure, gamma curves and white point functionality are not included
in this node, as there are native ways of doing that in the compositor.
These settings are marked non-editable in the Python API.

Mistake in refactor of Relocate code in a1abf9a64e, the handling of
cases where a valid (exisitng, missing linked placeholder ID) was not
found in the searched library(-ies) was not handled properly in the new
code.
These need to be ignored by remapping from old to new (relocated) IDs,
since it's better to keep the placeholder 'empty reference' IDs, than
remap to null!
This commit changes the internal storage and user-facing representation
of the brush size values (`size` and `unprojected_size`) from radius
to diameter.
This has a number of benefits:
* While the radius is more helpful for many internal operations, it is
more natural to estimate the size of a brush by the diameter
* Because the pixel size is stored as an integer, users are currently
unable to make brushes that have an odd numbered diameter, notably
preventing the ability to make single pixel brushes.
Internally, the `Brush` and `UnifiedPaintSettings` size values are
versioned to double their on-disk values. The relevant `BKE` functions
that access the data return the radius at runtime, and any internal
`struct`s that stored radius continue to do so.
The 'Radius' text for brushes is changed to 'Size' and all references
to it in descriptions are changed to 'size' as well.

This commit changes the face_ptex_offset from a manually managed int
array to a blender::Array. This required a number of changes:
* The `Subdiv` struct is no longer trivial, so MEM_new and MEM_delete
need to be used
* The Draw module API has an overloaded set of `origindex_buffer`
methods created to take in a Span instead of an int pointer and size

Currently, sequencer structs contain several pointers to data within
other structs. These pointers need to be remapped as the structs are
reallocated when reading from blend files. That has worked so far
because the pointers are exactly the values from the Blender session
that saved the file. With the implementation of #127706, the pointers
in the file aren't "real" anymore, and we can't offset them to get the
struct that contained the data. I'm working on the pointer stability
solution now to address a memfile undo performance regression
in 5.0 due to the `AttributeStorage` read/write design.
This commit replaces these 4 mid-struct pointers to point to the
containing strips instead, and uses some trivial logic to access the
fallback root sequence channels and strips. This makes the pointer
remapping on file load possible again.
This change is backward compatible but not forward compatible.

The pattern of transforming many position vectors at once is quite
common, both with separate source and result arrays, and when modifying
an array in place. In some cases at least we used a separate function
with a consistent name across files, but there were also many duplicate
parallel transform implementations.
This commit adds these utilities to the BLI_math_matrix.hh API and uses
them where many positions from contiguous arrays are transformed at
once. While there might be a more ideal location for these utilities,
it's consistent with 3936d7a93e, and certainly better
than duplicating them.
This also reduces binary size of my build by 15 KB.

While handling this pointer is technically not needed in `foreach_id`
code (and likely never will be), better not rely on such undocumented
implicit specifics, and instead properly handle it there, with comments
and asserts explaining why it should not be actually executed in current
code.

Previously, `VArrayImpl` had a `materialize` and `materialize_to_uninitialized`
function. Now both are merged into one with an additional `bool
dst_is_uninitialized` parameter. The same is done for the
`materialize_compressed` method as all as `GVArrayImpl`.
While this kind of merging is typically not ideal, it reduces the binary size by
~200kb while being basically free performance wise. The cost of this predictable
boolean check is expected to be negligible even if only very few indices are
materialized. Additionally, in most cases, this parameter does not even have to
be checked, because for trivial types it does not matter if the destination
array is already initialized or not when overwriting it.
It saves this much memory, because there are quite a few implementations being
generated with e.g. `VArray::from_func` and a lot of code was duplicated for
each instantiation.
This changes only the actual `(G)VArrayImpl`, but not the `VArray` and `GVArray`
API which is typically used to work with virtual arrays.

For certain invalid meshes (BKE_mesh_is_valid returns false), the
corner space indices might be invalid. However, this is no different
than any other place that code relies on valid mesh inputs; there is
no reason for the face corner normals code alone to bear the burden
of checking for invalid input meshes. Typically we choose not to
slow down the common case or increase its complexity for checks
like this, and the assumption that all corners are in a fan space may
help to simplify this code in the future.
