In very specific cases, during intersection testing, `intersect` can
add polygons already checked as duplicates in the buffer that
corresponds to the rest of polygons that can form groups of duplicates.
As the buffer cannot have repeated indices, re-adding, even
temporarily, these duplicates can cause a buffer overflow.
While this may have some impact on performance, it's difficult to
predict these cases and thus add a buffer pad.
So the solution is to check if they are already duplicated.
The count wasn't clamped above zero in some newly optimized code.
Instead of adding it there, move the clamping to the field network,
similar to some other nodes. That makes it so the rest of the code
doesn't have to deal with the clamping, and should be faster in the
single-value case.
When subsampling was introduced in VSE it was disabled during
editing. Only when rendering it was enabled. This lead to
cache being different between editing and rendering. Leading
to confusion.
This PR will enabled the subsampling when editing. This way
it is more consistent.

Some checks here are really critical and should assert, but that one is
more an indication that something is not going right, though data itself
should still be mostly valid, so better warn the user with a LOG
warning, than be silent in release builds, and crash in debug ones.
Invalid nodes are not added to the lazy-function graph. Therefore, their
outgoing links are also not added, which implies that the targets need
some default value.
The correction bbc6bb3468 was still wrong because there it was
disregarded that `vert_ctx_len` does not necessarily indicate merges in
the same polygon.
Therefore, it is not safe to rely on `vert_ctx_len` to count possible
new polygons.
NOTE: It might be worth preempting part of the
`weld_poly_split_recursive` logic to identify what the new polygons are
in advance. But this can be left for a future refactor.
Node tree updates can crash if the tree contains a node group that points at an "undefined" tree type.
This can happen if the tree is linked from a library and the path is lost,
or if a custom (python) tree is used and the script is not run.
The fix is to check if the node group type is valid ("registered") and return an empty list otherwise.

Pick select is only meant to change a single element from a single
data-block. However, the operator worked on each object individually
rather than first finding the closest point, then processing the
selection. Change the operator to find the closest point across all
objects, then deselect if necessary, then select the closest point.

After ed870f87b9, panels headers displayed inside panels had their

string comparison was made against the original message, instead of
the translated message.

- "Lines" in the sense of number of lines
- "Number" can mean "amount, count" or "index, offset"
- "Second" can be an ordinal number or a unit
- "Root": add the brush curve to the "square root falloff" sense
- "Strip" can be a sequence or a type of hair rendering
- "Constant" in the sense of a value, for the Geometry Nodes add
submenu (#105447).
Additionally, extract:
- "Press a key" from the Keymap preferences.
- "MaskLayer", upon new mask layer creation

This was caused by an incorrect assumption in the solver:
It tries to solve both collision and length constraints simultaneously,
using the projected movement of a point as a slide direction along the surface.
This only works if the distance of the previous curve point to the surface
is less than the allowed segment length. Otherwise the segment will
exceed the allowed length even with zero slide and NaN values are computed.
The case of larger surface distance can occur if the previous segment
solve was already stretching the current segment and then the point
moves further away. In this case we can simply clamp the segment length
without violating the contact constraint.
Pull Request #105499
3e5ce23c99 introduced a regression in case the freed Main was part of a
list, and was supposed to be removed from it, since calling
`BLI_remlink` does _not_ clear the `prev`/`next` pointers of the removed
link.
This commit also contains a few more tweaks to recent related b3f42d8e98
commit.
Pull Request #105485
While this behavior can be useful in some cases, it can also create
issues (as in one of own recent commits, 3e5ce23c99), since it
implicetly keeps the removed linknode 'linked' to the listbase.
At least warn about it in the documentation of `BLI_remlink`.
This commit introduces a new Main boolean flag that marks is as invalid.
Higher-level file reading code does checks on this flag to abort reading
process if needed.
This is an implementation of the #105083 design task.
Given the extense of the change, I do not think this should be
considered for 3.5 and previous LTS releases.
When render is triggered from python and the render result is displayed
it isn't being updated as it wasn't tagged as being invalid.

If the texture image path in the MTL is a "quoted" absolute path, the importer will fail to find the
file. It was only attempting to un-quote the path for the relative case. Now we attempt to un-quote
in all cases.

The issue was that when using the `HD_ALIGNED` handle type,
Blender would not automatically move the keyframe handles with the key.
Instead one handle would get stuck in place.
To remedy that manually move the keyframe handles in case the type is `HD_ALIGNED`
This makes it consistent with moving a key with G

Consistently use edge draw flag instead of original index to determine if an
edge should be drawn or not.
In GPU subdivision the edge original index was used for both edge optimal
display and selection mapping to coarse edges, but they are not the same.
Now match the CPU subdivision logic and use a separate edge draw flag VBO.
For cage display, match Blender 3.3 behavior more in showing/hiding of edges
in wireframe mode. That is edges without a mapping to an original edge are
always hidden when there is no distinct cage, and drawn otherwise. This is
not ideal for e.g. the bevel modifier where it will always show some edges on
corners despite all edges being hidden by the user. But we currently have
no good information to decide if these should be hidden or not, so err on
the side of showing too much as it did before.

Fix#103700: optimal display can't be turned of with GPU subdivision
Fix wrong edge display with GPU subdivision preceded by other modifiers

Timer management code often loops over the list of timers, calling
independant callbacks that end up freeing other timers in the list. That
would result in potentail access-after-free errors, as reported in #105160.
The typical identified scenario is wmTimer calling wmJob code, which
calls some of the job's callbacks (`update` or `end` e.g.), which call
`WM_report`, which removes and add another timer.
To address this issue on a general level, the deletion of timers is now
deferred, with the public API `WM_event_remove_timer` only marking the
timer for deletion, and the private new function
`wm_window_delete_removed_timers` effectively removing and deleting all
marked timers.
This implements design task #105369.

Window activation events on Windows-10 don't seem to be reliable as it's
possible for Alt-Tab to trigger WM_ACTIVATE on a window when switching
away from it. As detecting the keys which are held relies on a valid
active state - this meant Alt could become stuck when using Alt-Tab
to switch between windows.
Disable reading modifiers on activation for WIN32, activating the window
now clears modifiers on WIN32. This isn't ideal as held modifiers wont
be detected, re-introducing the error reported in #40059.
Previously, UBO bind locations were linearly incremented and
relied on the correct uniform location being queried. This fix
is a future requirement for EEVEE next, however, pulling forward
due to Issue #105280 highlighting a possible flaw with expected
uniform locations.

Intel GPUs exhibit a number of rendering artifacts.
The most substantial being incorrect resolve of reflections.
Splitting the reflections_resolve shader into two passes,
one for SSR and one for light probes ensures correct rendering
and optimal performance on this GPU.
Also resolves an artifact with ambient occlusion wherein
the pow(a, b) function causes excessive precision loss.
Using an alternative method for power calculation on these
platforms resolves the issues.

Pull Request #105184
Grease Pencil (when not in object mode) implements its own selection
opertor. This operator (`gpencil.select`) returns
`OPERATOR_PASS_THROUGH`, then falls though to `view3d.select` which can
toggle object selection (when using shift-click picking).
Removing `OPERATOR_PASS_THROUGH` would fix the object toggling, but this
was added in 62c73db734 with good reason (the tweak tool would not
work then).
Now prevent `view3d.select` from acting on Grease Pencil (when not in
object mode).
NOTE: longer term we could have grease pencil use view3d.select to avoid having to add these awkward exceptions
Pull Request #105342
Windows 11 has strange behavior with Alt-Tab.
In some cases an Alt-Press event is sent to the window immediately
after it is de-activated (both Left & Right Alt keys for some reason
even when only one is held).
This meant that:
- Modifiers could be enabled for de-activated windows
(so we can't assume de-activated windows have modifiers released).
- Releasing the modifier key would not be sent to the inactive window
causing the modifier key to be stuck.
- Button events over an inactive window are generated before activation,
so even though activation reads the correct modifier state,
the button event uses the "stuck" modifier state.
Now button & drop events on inactive windows always read the modifier
state first instead of relying on the modifier state to be cleared.
This has some advantages:
- If modifiers are held, they will be used as part of the click action.
- While modifier keys on inactive windows should be rare,
in the case this does happen - stuck keys are avoided.
So it makes sense to apply these changes for all platforms.
Also remove USE_WIN_ACTIVATE & USE_WIN_DEACTIVATE defines as they
were only added when changes to modifier handling failed on WIN32.
This logic has now been tested to work on all platforms.
