The issue was that the pointcache was not storing dead particles,
even though they are displayed. This lead to the rendering issue,
because only alive particles can be read from the point cache in
the frame that is rendered.
This also fixes an issue unrelated to rendering: when dead particles
are displayed, their position is incorrect when some frames are
skipped during playback.

Keep braces balanced where possible, even with ifdef's as it avoids
confusions with editors calculating correct indentation level &
finding matching brackets.
This patch tries to sanitize the types of our size parameters across our read
and write code, which is currently fairly inconsistent (using `int`, `uint`,
`size_t`...), by using `size_t` everywhere. Since in Blender file themselves
we can only store chunk of size `MAX_INT`, added some asserts to ensure that
as well.
See {T79561} for details.

Collections of liboverride data only support insertion of new items (and
deleting or moving those around). No operation on existing items from linked
data is allowed.
Reflect that in RNA functions used to edit py-defined RNA collections.
Note that this is not ideal currently, it does the job but feedback to
user is rather poor. Ideally add-ons should implement higher-level
checks for override cases in their operators.
Supporting IDProperty-based data storage here in a generic way is fairly
simple, unlike actual RNA data (DNA-based), for which getting a proper
generic way to duplicate them from within RNA is currently not really
possible.

Warp & weight vertex-group editing modifiers miscalculated vertex weight
inversion, the weights were multiplied before being subtracted from 1.
Ref D8241
Build modifiers linked or copied to objects from the outliner would not
animate until the file was saved and reopened due to a missing depsgraph
relations tag.
Expanded objects with children immediately after a colored collection
would have the color applied to their hierarchy lines as well. The fix
is to reset the collection color to `COLLECTION_COLOR_NONE` for each
open subtree.

This is a simple trick that does *not* have a huge performance impact but
does work pretty well. It just modifies the Fresnel term to account for
the multibounce energy loss (coloration).
However this makes the shader variations count double. To avoid this we
use a uniform and pass the multiscatter use flag inside the sign of f90.
This is a bit hacky but avoids many code duplication.
This uses the simplification proposed by McAuley in
A Journey Through Implementing Multiscattering BRDFs and Area Lights
This does not handle area light differently than the IBL case but that's
already an issue in current implementation.
This is related to T68460.

The search should check if a panel is active before changing its
expansion, otherwise it sets the expansion for all of the region's
panels, even invisible ones in other tabs.
This was causing flashing colors in the node editor grid.
This is because in some cases the flat color is only set on the provoking
vertex which is the last of the primitive by default.
This makes wide line supported on MacOS and other implementation that
does not support wide line by default.
This workaround works for all Line types but only if using one of the 5
default shaders.
The workaround is completely isolated and invisible to the outside. It has
no side effect.
Note: This does not affect the GPUBatch drawing.
This is not an exhaustive change, just for the 2D cursor and
UDIM grid properties. Also vertically align the "UV Vertex"
buttons like in the 3D view panels.
Checking for the layout alignment is not a reliable way to filter out
which items need the additional icon/text offset. Instead check if the
buttons are icon-only (which we rarely do, e.g. for collection colors in
the Outliner context menu).
For example you can now start entering text in the Properties or
Outliner search, and press the 'x' while the button is still in
text-edit mode.
This way you don't have to exit text editing first, before being able to
quickly clear the string with a mouse click. So this is a small
improvement for convenience.
It also works for the eyedropper (change to picking an object while text
editing) or the '+' and '-' icons in the file saving dialog.
E.g. the 'x' icons or eyedropper icons in text buttons. They didn't use
to have any mouse over feedback, now we dim the icon until hovered.
This kind of feedback helps users see that the icons are interactive,
and if they are within their interaction hotspot.
I think this wasn't allowed before because the section of a curve was
built in multiple parts. But since rBe34d3e32dda7, the whole slice
of a curve is built in one piece, so we can easily support curve
caps for all geometry types, including the new custom profile option.
Note that this also allows "caps" when the fill type is not full.
They could easily be disabled by checking for "Full" fill type
if that was preferred in the future.

This adds XYZ symmetry as a property of meshes and updates all modes to

This object operator exits and frees the edit data of the
current object and enters the same mode in another one in a single step,
without going through object mode or keeping multiple edit object data
active. It is assigned to the D key.
This solves all conflicts that the right/click select keymap and the
emulate 3 button mouse produces for this operation and it is independent
of the state of Lock object modes.
Also, as the SculptSession is freed, when using Multires objects go
back to their preview resolution level, so it is possible to work on
high vertex count scenes without slowing down the viewport and other
performance problems.

This implements a new overlay that blends the bakground color over the
objects that are not in the same mode as the active object, making
them fade with the background.
This is especially needed for sculpt mode as there is no other overlay
or indication in the viewport to display which object is active.
This is intended to be used with D7510 in order to have a faster
workflow when sculpting models with multiple objects.

This adds an option for the HDRI rotation to follow the view rotation.
When this option is enabled, this allows EEVEE materials to be used as
matcaps for sculpting and painting.
This has an extra performance cost when orbiting around the model as the
lookdev cache needs to be recalculated, but in my test it is barely
noticeable.

This filter scales the mesh as it was a softbody, producing folds in the
surface. The orientation of the folds can be controlled using the filter
axis and orientation.
This is an example of a cloth filter that uses deform coordinates instead
of forces, but probably it does not make much sense to expose it to the
user in a different way and with different parameters. I'll remove
FilterCache->enabled_force_axis in a later commit and use always
enabled_axis in SCULPT_filter_zero_disabled_axis_components
for both forces and deformation filters, so this function can also be used
in the mesh filter.

The deformation constraints strength were too strong and they were
preventing the cloth effects of the brushes with cloth deformation target
to create folds properly. This lowers the default, making the simulation
follow the deformation in a more relaxed way.
I'll make a separate patch to expose this as a property for certain brushes
and cloth deformers that may need higher values (like boundary with loop
falloff on a low poly mesh), but I think this default will work better for
most use cases.

This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas.
After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.
