This is clearer about what is actually happening (VArray is small
enough to be a by-value type and is constructed on demand, while
only the generic virtual array is stored).
The node had incorrect handling of instance attributes. For the instance
component, instead of using the instance domain over the point domain,
it just looked through instances recursively when retrieving attributes.
We never want to do that, since we only work on one geometry at a time.
Instead, just switch out the instance domain for the point domain like
the set position node.

The COLLADA importer was silently ignoring the alpha component in the
vertex data.
The `stride` variable holds the component count (3 for RGB; 4 for RGBA),
and can be used for honouring the alpha channel in the vertex data.
Test plan:
- Open Blender.
- Clear the scene.
- Add a plane.
- Enter **Vertex Paint** mode.
- Switch to the **Erase Alpha** blending mode.
- Select a tone of gray.
- Turn strength down to less than 1
- Paint [some of] the vertices of the plane.
- Export project as a COLLADA file (`.dae`).
- Clear the scene.
- Re-import the COLLADA file again.
- Export the project again (with different name).
**Without** this patch, the second exported project will have lost the
alpha component in their vertex data:
```lang=xml, counterexample
<float_array id="Plane-mesh-colors-Col-array" count="24">1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1</float_array>
```
**With** the patch, the first and the second exported projects retain
the alpha values painted previously:
```lang=xml
<float_array id="Plane-mesh-colors-Col-array" count="24">1 1 1 1 1 1 1 0.5490196 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0.5490196</float_array>

This modules handles renderpasses allocation and filling. Also handles
blitting to viewport framebuffer and render result reading.
Changes against the old implementation:
- the filling of the renderpasses happens all at once requiring
only 1 geometry pass.
- The filtering is optimized with weights precomputed on CPU and
reuse of neighboor pixels.
- Only one accumulation buffer for renderpasses (no ping-pong).
- Accumulation happens in one pass for every passes using a single
dispatch or fullscreen triangle pass.
TAA and history reprojection is not yet implemented.
AOVs support is present but with a 16 AOV limit for now.
Cryptomatte is not yet implemented.
Removes the following macros for scene/render frame values:

- `SUBFRA`
- `SFRA`
- `EFRA`
These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):
```
CFRA = some_frame_nbr;

Revert length position and offset handling for sound strips so their
position does not change and remap fcurves to new `speed_factor`

Previously, it would show "Link inside collection" but move between collections

Use client (window) relative coordinates for cursor position access,
this only moves the conversion from window-manager into GHOST,
(no functional changes).
This is needed for fix a bug in GHOST/Wayland which doesn't support
accessing absolute cursor coordinates & the window is needed to properly
access the cursor coordinates.
As it happens every caller to GHOST_GetCursorPosition was already making
the values window-relative, so there is little benefit in attempting to
workaround the problem on the Wayland side.
If needed the screen-space versions of functions can be exposed again.
Grease Pencil animation channels are now also shown in the Dopesheet
mode of the Dopesheet editor and in the Timeline.
Grease pencil related events are now listened not only by container
`SACTCONT_GPENCIL` (Grease Pencil Dopesheet), but also
`SACTCONT_DOPESHEET` (main Dopesheet), and `SACTCONT_TIMELINE`
(timeline).
A new Animation Filter flag was added: `ANIMFILTER_FCURVESONLY`. For now
this only filters out Grease Pencil Layer channels.
**Implemented:**
- Preview range set: now only considers selected Grease Pencil keyframes
when `onlySel` parameter is true. Not only this allows the operator to
work with grease pencil keyframes in main dopesheet, but it also fixes
the operator in the Grease Pencil dopesheet.
- Translation: allocation (and freeing) of specific memory for
translation of Grease Pencil keyframes.
- Copy/Paste: call to both Fcurve and GPencil operators, to allow for
mixed selection. Errors are only reported when both the FCurve and
GPencil functions fail to paste anything.
- Keyframe Type change and Insert Keyframe: removed some code here to
unify Grease Pencil dopesheet and main dopesheet code.
- Jump, Snap, Mirror, Select all/box/lasso/circle, Select left/right,
Clickselect: account for Grease Pencil channels within the channels
loop, no need for `ANIMFILTER_FCURVESONLY` there.
**Not Implemented:**
- Graph-related operators. The filter `ANIMFILTER_FCURVESONLY` is
naively added to all graph-related operators, meaning more-or-less all
operators that used `ANIMFILTER_CURVE_VISIBLE`.
- Select linked: is for F-curves channel only
- Select more/less: not yet implemented for grease pencil layers.
- Clean Keys, Sample, Extrapolation, Interpolation, Easing, and Handle
type change: work on Fcurve-channels only, so the
`ANIMFILTER_FCURVESONLY` filter is activated
Graying out these operators (when no fcurve keyframe is selected) can be
done with custom poll functions BUT may affect performance. This is NOT
done in this patch.
**Dopesheet Summary Selection:**
The main summary of the dopesheet now also takes into account Grease
Pencil keyframes, using some nasty copy/pasting of code, as explained
[on devtalk](https://devtalk.blender.org/t/gpencil-layers-integration-in-main-dopesheet-selection-issue/24527).
It works, but may be improved, providing some deeper changes.

Regression caused by the introduction of partial resync in February 2022
(rB1695d38989fd482d3c). Code was missing adding some existing overrides
to the mapping in some specific cases, causing resync to create 'new'
ones instead of re-using existing ones.
This commit also adds a basic resync testcase that illustrates this
issue.
This reverts commit rB31d80ddeaad, and fixes issue introduced in rBf0b4aa5d59e3
by not doing the 'reversed dependency check' in resync case.
Rational here are:
* Supporting reversed dependency in a reliable, coinsistent way in
resync is likely to be a nightmare, if even possible at all.
* Needs for such reversed dependency in resync should be close to 0% of
cases, as long as users remain reasonable with their organization of
their assets (it could only become a problem in extreme bad practice
and corner cases, like a geometry object being added as a child of a
rig in a completely new, otherwise un-overridden collection, in
partial override context).
This decision may need to be re-evaluated later in case we go more
towards a very highly partial-override workflow, but even then I would
expect current solution to work fine in all reasonable use cases.
Fix unused function result warnings for usages of `fread` in the C++
.stl importer, by actually using the returned error code.

This commit adds a new face nearest snapping mode, adds new snapping
options, and (lightly) refactors code around snapping.
The new face nearest snapping mode will snap transformed geometry to the
nearest surface in world space. In contrast, the original face snapping
mode uses projection (raycasting) to snap source to target geometry.
Face snapping therefore only works with what is visible, while nearest
face snapping can snap geometry to occluded parts of the scene. This new
mode is critical for retopology work, where some of the target mesh
might be occluded (ex: sliding an edge loop that wraps around the
backside of target mesh).
The nearest face snapping mode has two options: "Snap to Same Target"
and "Face Nearest Steps". When the Snap to Same Object option is
enabled, the selected source geometry will stay near the target that it
is nearest before editing started, which prevents the source geometry
from snapping to other targets. The Face Nearest Steps divides the
overall transformation for each vertex into n smaller transformations,
then applies those n transformations with surface snapping interlacing
each step. This steps option handles transformations that cross U-shaped
targets better.
The new snapping options allow the artist to better control which target
objects (objects to which the edited geometry is snapped) are considered
when snapping. In particular, the only option for filtering target
objects was a "Project onto Self", which allowed the currently edited
mesh to be considered as a target. Now, the artist can choose any
combination of the following to be considered as a target: the active
object, any edited object that isn't active (see note below), any non-
edited object. Additionally, the artist has another snapping option to
exclude objects that are not selectable as potential targets.
The Snapping Options dropdown has been lightly reorganized to allow for
the additional options.
Included in this patch:
- Snap target selection is more controllable for artist with additional
snapping options.
- Renamed a few of the snap-related functions to better reflect what
they actually do now. For example, `applySnapping` implies that this
handles the snapping, while `applyProject` implies something entirely
different is done there. However, better names would be
`applySnappingAsGroup` and `applySnappingIndividual`, respectively,
where `applySnappingIndividual` previously only does Face snapping.
- Added an initial coordinate parameter to snapping functions so that
the nearest target before transforming can be determined(for "Snap to
Same Object"), and so the transformation can be broken into smaller
steps (for "Face Nearest Steps").
- Separated the BVH Tree getter code from mesh/edit mesh to its own
function to reduce code duplication.
- Added icon for nearest face snapping.
- The original "Project onto Self" was actually not correct! This option
should be called "Project onto Active" instead, but that only matters
when editing multiple meshes at the same time. This patch makes this
change in the UI.

This commit adds new Unwrap and Pack Islands nodes, with equivalent
functionality to the existing Unwrap and Pack Islands operators. The
Unwrap node uses generic boolean attributes to determine seams instead
of looking at the seam flags in the mesh geometry.
Unlike the Unwrap operator, the Unwrap node doesn't perform aspect
ratio correction, because this is trivial for the user to implement
with a Vector Math node if it is desired.
The Unwrap node implicitly performs a Pack Islands operation upon
completion, because the results may not be generally useful otherwise.
This matches the behaviour of the Unwrap operator.
The nodes use the existing Vector socket type, and do not introduce a
new 2D Vector type (see T92765).

resulting in a missing UBO bind.

Patch implements better way to control playback speed than it is
possible to do with speed effect. Speed factor property can be set in
Time panel.
There are 2 layers of control:
Option to retime movie to match scene FPS rate.
Custom speed factor to control playback rate.
Since playback rate is strip property, it is now possible to manipulate
strip as normal one even if it is retimed.
To facilitate manipulation, some functions need to consider speed factor
and apply necessary corrections to strip offset or strip start. These
corrections may need to be float numbers, so start and offsets must be
float as well.
Sound strips now use speed factor instead of pitch. This means, that
strips will change length to match usable length. In addition, it is
possible to group movie and sound strip and change speed of meta strip.
