The recently introduced size, strength, and jitter pressure curves
affect most paint code. This exposed further odd behavior inside
`paint_brush_update` where the size pressure curve was being evaluated
even if the brush's size did not vary with pressure.
To fix this issue, this commit clarifies a few comments and updates the
code flow such that cached input values and evaluated pressure values
are used more consistently.

Rewrite the "mesh is valid" and "validate mesh" functions to be more
agnostic of the custom data storage system, align with the changes to
topology storage in the last 5 years, be much clearer overall, more
reusable.
Each check is implemented as a separate pass over the remaining
valid geometry in the mesh, producing an IndexMask of the invalid
elements it finds. At the cost of some extra iteration over mesh elements,
this should make each requirement clearer and make it easier to
optimize and reuse each check if needed.
The code is roughly twice as fast as it was before. I measured 92ms
instead of 200ms for a 1 million vertex cube on a Ryzen 7950X.
There's a bit of low hanging fruit for further optimization too.
There are now automated tests just for the validation code as well.
For now they are very basic but they could be extended in the future.
Some non-obvious points:
- The new face offsets storage (replacing `MPoly`) upholds more
invariants by itself. Previously faces could easily overlap or leave
corners unreferenced. That doesn't really happen anymore, but
bad offset values are a more "global" problem.
- The validation code for the old "MFace" storage was removed. It is
just rebuilt when it's needed at runtime anyway, so there isn't much
point in validating it.
- The versioning code for 2.90.1 was calling the mesh validation code
to fix an issue where the extrude manifold tool could generate bad faces.
Unfortunately keeping that would mean being unable to remove the old
code, so now there's a warning to open and save the file in a previous
version instead.
- One of the main goals of the new code is better const correctness, and
working better with implicit sharing. The code now only requests mutable
copies of the mesh data if it has to change.

This was caused by 3dfec1ff73
which introduce the new behavior. This was to fix workflows
using a lot of semi-transparent objects which made nagivation
difficult.
This patch first roll back to the previous behavior: The
unselectable object will affect depth-aware operators.
This patch introduces a new visibility property to remove
the influence of objects in all depth picking operations
and selection operations. However the object is still
selectable through non-drawing selection operators
(e.g. select by material) and through the outliner.
This is to adress the aforementionned navigation issues.

644fb2b679 fixed a long standing issue
that offscreen example showed the wrong colors. However the fix assumes
that input texture color space is always sRGB.
This adds a shader variation that draws textures that are stored in scene referred
linear color space (like all of our Image data-block).

Adding panel toggles in nodegroups have somewhat of a UX antipattern. When
running the operator, it checks for conditions that indicate it should not run,
and if those are hit, it cancels execution and mentions the invalid condition in
the footer bar.
This is not ideal, the user should not have to call the operator to find out
whether it can be called.
Why it got implemented like this is likely a consequence of all interface items
being the same "New Item" operator. Poll functions cannot use operator
properties, so variants of the same operator cannot check for different
conditions for execution.
This is a problem for panel toggles, as they have more restrictions to when they
can be added that don't apply to other interface items.
This patch creates a separate operator for adding panel toggles. This allows the
condition checks to be implemented in the poll function, which enables greying
out the operator buttons and showing on tooltips what condition is invalid.

The issue was that the data-blocks of two different undo steps were detected to
be identical, even if the attributes changed. That's because even if the
implicitly-shared data was different, they were turned into the same pointer by
cadb3fe5c5 on write.
This patch makes it so that for undo steps, implicitly shared data does not use
the pointer stability feature (in a sense, implicit-sharing itself provides
pointer stability for undo steps already).
The main tricky aspect is that we need to know if a pointer is implicitly shared
in `writestruct_at_address_nr` and oftentimes that's called before the
corresponding shared data is actually written with `BLO_write_shared`. The
solution is to enforce that the blend-write code has to know what pointers are
implicitly-shared before they are written the first time. The simplest way to
ensure that is to call `BLO_write_shared` first. However, that's not always
possible, especially when the pointer is directly embedded in an ID. Therefore,
there is a new `BLO_write_shared_tag` function that can be used in such cases.
The undo performance for the file in #141262 is still fixed with this change.

When saving asset catalogs to an already-existing file, only perform
that save when there were local changes to the catalogs. This prevents
unnecessary writes to the catalog definition file, as that can cause
conflicts when multiple Blender instances share the same asset library
(either directly or via Syncthing/Dropbox/etc.)

This has ripple effects by making the "hide value" setting ineffective and
always hiding socket values as well as graying out the "hide value" node group
option.

The bone collection operator was not updated to handle the new flag
which is now on the `bPoseChannel` instead of the `Bone`.
For this to work, the operator now needs the `bArmature` as well as the `Object`
and they need to be in sync. Additional code was added to the poll function
to ensure this is the case.
As a bonus, when working with multiple armatures this now works as expected
where only the bones of the active armature are selected even if the armature is
shared. The active object is determined by the last bone clicked.

When connecting node sockets, a search menu opens. Its items need to
be added, and translated manually. This commits adds a few missing
items from recent nodes.
It does the same for sockets coming from node group assets.

Brush directions are dynamic, the enum can have different options
depending on brush type. This commit manually extracts the options.
The labels use the "Brush" translation context, to disambiguate
"Deflate", the operation, with the compression algorithm.
Also `smooth_direction_items` is moved inside
`rna_Brush_direction_itemf()`, since it is used only there, same as
the other brush direction items.

When select-sync was used with both edge & face modes enabled,
vertex selection logic was used which resulted in no visible selection.
Now edge selection is used when both edge and face modes are enabled.
Ref !148181
Implement pinned with select-sync (technically not a bug),
more an oversight in !138197.
Some subtle functional changes have been made.
- Select pinned now only works in vertex select mode
since previously it was possible to select vertices in edge/face modes
where the selection wasn't displayed.
- The island selection option is ignored when selecting pinned.
- The select pinned operator wasn't working with select sync edge/face
modes. Exits with an error instead.

PRs #147511 and #147595 ensured that any check for scene strip renders
in the prefetch thread would also recurse into "sequencer-type" scene
strips, but this introduced the potential for an infinite recursion.
Fix by using `SeqRenderState` to detect such a recursion.
Also remove unused `seqbasep` context member in `PrefetchJob`, and
add a check for non-nullptr `Editing`, fixing a crash where the scene was
present without an `Editing` counterpart.

Add a simple check to the Marker keymap poll. Since there's no `bContext`
passed to the function we can reconstruct it from the workspace.
We can exit early if there is no sequencer scene (when no markers are
guaranteed). View layer can remain the same since it only applies in the
`SPACE_ACTION` case.

`socket.socket_typeinfo()` can be nullptr when reading blend files that

The descriptions for `POSELIB_OT_asset_modify` and
`GEOMETRY_OT_execute_node_group` are dynamic. They were already
extracted, but the translation did not happen in the description
function.
This commit adds the appropriate `TIP_` translation macro.
Reported by Ye Gui in #43295.
The "Unassigned Node Tools" menu type is declared manually in a
function, and its label is not automatically translated. This commit
extracts it using `N_()`. Note that its description was already
extracted the same way.
