time change
followup to 815ca2310f, this one fixes the RNA_MeshLoopColor case, adds
RNA_VertexGroupElement and RNA_LatticePoint.
coop with @sergey, thx.
Fixes T68666
The parent hairs were written to Alembic even when the 'Parent Particles'
checkbox (`use_parent_particles`) was disabled. In this case the parent
hairs were not correct in Blender's memory, and thus also not correct in
the exported Alembic file. The Alembic exporter now respects this setting
and doesn't write the parent hairs when 'Parent Particles' is off.
Steps to reproduce were:
* Add a new collection
* Put an object into it
* Exclude the selection (the checkbox in front of the name)
* Enable "Local Collections" in any viewport
-> Crash
Did not skip the excluded collections, causing an unsuccessful object
lookup (returned null-pointer).
The problematic video from T68091 clearly has an invalid stream duration
(it would be 55 centuries long if interpreted at 30 FPS, and given that
it was recorded with an Android 9 device, it's unlikely that recording
started that long ago). I've added a heuristic to check the stream
duration against the container duration; if the stream is more than 4x
longer than the container, Blender now falls back to the container
duration.
We could use MIN(stream duration, container duration), but there might
be video files out there where the container duration is less precise
than the stream duration; they are measured in different units of time
(microseconds for the container vs. frames for the stream).
Includes a unit test for the above heuristic.

This was introduced in FFmpeg lavf 55.1.100 in 2013. For systems that are
still on LibAV or older FFmpeg there is a fallback implementation that
performs the same guess as we did before in `av_get_r_frame_rate_compat()`.
There is now a clearer distinction between `video_stream` (the stream itself)
and `video_stream_index` (its index), and no more repetition of accessing
the same item of an array. This also makes the code a bit more readable in
preparation for an upcoming functional change.
From rBe7a514369fe70, since I did not have time to do proper review
in D5808...
Note that we could also consider that shallow copy of src should never
be dst of that function and add some asserts instead. For now going the
safest and simplest way though.
This is a regression since PBVH was introduced for weight paint.
The solution is: treat subsurf and multires modifiers as deforming
ones for the weight painting. This is an easiest solution to make
PBVH use subdivided location of original vertices.
This change could simplify some of the weight paint by removing
the grids check, since PBVH is not supposed to be built from grids
in this case anymore.

Currently unused but the intention is to use this to hook up these
modifiers to a generic deformed PBVH to make it easier to sculpt or
paint on a subdivided mesh.
The problem was that the object and collection pointers in Base and
LayerCollection would get lost of file read. Normally such ID pointers would
be resolved by pointing to an ID_ID placeholder which has the datablock name,
and then replacing it will the real datablock. However ID_ID is only written
for directly linked datablocks.
This adds the concept of an indirectly linked datablock with a weak reference
to it. For this we write an ID_ID_WEAK_REF code, which is a reference that
will only be resolved if the datablock was read for another reason.

Modifier stack evaluation would copy mesh settings other than mesh topology
automatically, outside of the individual modifier evaluation. This leads to hard
to understand code, and makes it unclear which settings are available in following
modifiers, and which only after the entire stack is evaluated.
Now every modifier is responsible to ensure the mesh it outputs preserves materials,
texture space and other settings, or alters them as needed.

Knife project switches out of vertex selection mode, but wouldnt do this
for all participating meshes.
Logic in edbm_select_linked_pick would switch the viewcontext multiple
times and the meshes selectmode was not in sync then, leading e.g.
finding a vertex in 'unified_findnearest' (because last of the meshes
selectmode was SCE_SELECT_VERTEX), but then later in
'EDBM_elem_from_selectmode' other meshes selectmode was not matching
SCE_SELECT_VERTEX, leading to crash...

As the layer and frame memory was duplicated, the pointers were connected to old data. This was solved when saved the file, but this was a bug. Also this required a duplication and clean all listbase items.
Now, instead to duplicate and clear memory for layers and frames, just create a new layer and frame. This solution fix the problem, it's faster and also keeps the code cleaner.
This commit also removes the name "voxel" from the messages because this function
is now used for the voxel remesher and quadriflow.

Particularly noticeable when vertex painting with a subsurf modifier.
In some cases every sculpt or paint stroke step would evaluate the dependency
graph. This should only happen for redraws. Now more selectively choose if the
dependency graph should be evaluated to initialize the view context. Doing it
in the view context evaluation is somewhat hidden, now it's more explicit.

That code is simpler and more general (not limited to some specific
values of thread numbers). It still gives similar default chunk size as
what we had before, but handles smoother increase steps, and higher
number of threads, by keeping increasing the chunk size.
No functional change expected from that commit.
When the grab brush was used in an empty frame, a new frame was created, but as the depsgraph was no tagged, the evaluated data was wrong and the Grab hash failed.
If children hairs were displayed in particle editmode, these would not
update when a particle was deleted.

The static mesh issue described in T65816 has been resolved by @Sergey
in T60094.
This commit fixes the last bit of the puzzle, which was two-fold:
- A missing depsgraph update when setting `orig_object.data = new_mesh`
from Python. Thanks @Sergey for providing the fix :)
- Properly locking the interface while exporting. This prevents crashes
as described in T60094. The previous approach of calling
`BKE_spacedata_draw_locks()` was not enough.
This reverts commit b962aca800. We may revert
to the fullscreen file browser if it's not good enough by the time of the 2.81
release. But then it first needs some changes since the in between state now
is not good enough either.
This allows to create different effects with some brushes that use the sculpt plane.
