Better estimate of number of output faces.

Avoids need to resize some arena vectors in many cases.

Added floating filters to the initial plane-side tests in tri-tri intersect.

Needed an "abs" function for double3, so added it to all of the
float/double/mpq 2/3 types.

Fix a strange merge problem, and fix a couple of warnings.

Fix T78959: Show current frame indicator when interface is locked

When the playhead drawing moved to an overlay, a check was added to keep
it from drawing with a locked interface. This is necessary for some overlays,
but not this one, so this removes the check, making it the responsibility of
the editor.

A context function is added to make that check easier in the future.

Fluid: Numpy support for Mantaflow build system

Adjusted the fluid build system so that plugins that depend on numpy can be compiled as well.

Note that in this commit numpy support is still disabled. It can be enabled by re-running the Mantaflow update script with USE_NUMPY=1 and enabling WITH_MANTA_NUMPY in extern/mantaflow/CMakeLists.txt. This will happen in a future commit.

Simulation: move initial simulation code from bf_blenkernel to bf_simulation

I removed bf_blenkernel from `nodes/CMakeLists.txt` again (added it yesterday),
because now this was causing me unresolved symbol errors... Without it, cmake
seems to link the libraries bf_simulation, bf_blenkernel and bf_nodes in the right
order. Not sure if that is just luck or if it is guaranteed.

It was possible to fix the issue by using cmakes `LINK_INTERFACE_MULTIPLICITY`,
but that is probably bad style.

Fix T77867: Link Duplicate Object crashes during batch creation

When using link duplicated objects it could happen that one object is
calculating the GPUBuffers and the second object is marking these
buffers invalid. This introduces threading issues.

This patch fixes this by combining the surface and surface per material
batches. Most likely the surface per material batches are used and when
requested you will most likely need the surface batch for the depth
tests and overlays.

During tests it slightly improves performance as batches aren't thrown
away without using it.

After this patch we can add a quick path for meshes with one material
and two materials.

Alternative approaches that have been checked:
- sync extraction per object: reduced performance to much (-15%)
({D8292})
- post checks: reduced the threading issues, but didn't solve it.
- separating preparation and execution of the extraction ({D8312})

Nodes: move some code from blenkernel directory to nodes

This also introduces the `blender::nodes` namespace. Eventually,
we want to move most/all of the node implementation files into
this namespace.

The reason for this file-move is that the code fits much better
into the `nodes` directory than in the `blenkernel` directory.

Tests: disable ASAN when discovering tests

CMake, when it's configuring the project, runs the `blender_test` test
runner (if it exists from a previous build) to discover which tests it
contains. At this time none of the tests themselves are run, so it's not
that useful to run ASAN and have it break things when there are memory
leaks.

This commit disables ASAN by injecting `ASAN_OPTIONS="detect_leaks=0"` in
the environment variables.

It is not enough to use `set(ENV{ASAN_OPTIONS} "detect_leaks=0")` in
`tests/gtests/runner/CMakeLists.txt`, as it wouldn't be passed to the child
process.

Tests: move tests from USD test directory into `io/common` and `io/usd`

This commit is a followup of {D7649}, and ports the USD tests to the new
testing approach. It moves test code from `tests/gtests/usd` into
`source/blender/io/common` and `source/blender/io/usd`, and adjusts the
use of namespaces to be consistent with the other tests.

I decided to put one test into `io/usd/tests`, instead of
`io/usd/intern`. The reason is that this test does not correspond with a
single file in that directory; instead, it tests Blender's integration
with the USD library itself.

There are two new CLI arguments for the Big Test Runner:

- `--test-assets-dir`, which points to the `lib/tests` directory in the
SVN repository. This allows unit tests to find test assets.
- `--test-release-dir`, which points to `bin/{BLENDER_VERSION}` in the
build directory. At the moment this is only used by the USD test.

The CLI arguments are automatically passed to the Big Test Runner when
using `ctest`. When manually running the tests, the arguments are only
required when there is a test run that needs them.

For more info about splitting some code into 'common', see
rB084c5d6c7e2cf8.

No functional changes to the tests themselves, only to the way they are
built & run.

T73268: Link C/C++ unit tests into single executable

This commit introduces a new way to build unit tests. It is now possible
for each module to generate its own test library. The tests in these
libraries are then bundled into a single executable.

The test executable can be run with `ctest`. Even though the tests
reside in a single executable, they are still exposed as individual
tests to `ctest`, and thus can be selected via its `-R` argument.

Not yet ported tests still build & run as before.

The following rules apply:

- Test code should reside in the same directory as the code under test.
- Tests that target functionality in `somefile.{c,cc}` should reside in
`somefile_test.cc`.
- The namespace for tests is the `tests` sub-namespace of the code under
test. For example, tests for `blender::bke` should be in
`blender::bke:tests`.
- The test files should be listed in the module's `CMakeLists.txt` in a
`blender_add_test_lib()` call. See the `blenkernel` module for an
example.

macOS: Support arm64 architecture.

Enabling all `make deps` dependencies with the exception of Embree and OIDN.
After that, Blender can be compiled on an Apple Silicon Mac just like on any
Intel based Mac. There are still compiler warnings that need to be
investigated and there are probably a couple of bug still to be discovered
and to be fixed.

Most patches to the dependencies are simple and are about disabling SSE and
setting the proper architecture to compiile for. Notable exception is Python,
where I back ported a yet to be accepted PR for upstream Python:
https://github.com/python/cpython/pull/21249

Cross compiling or buliding a Universal Binary is not supported yet.
The minimum macOS target version for x86_64 remains at 10.13, the target
for arm64 is 11.00.

PointCloud: Initial rendering support for Workbench

Also includes outline overlays. Removes the temp overlay drawing

We make the geometry follow camera like billboards this uses less
geometry. Currently we use half octahedron for now. Goal would be
to use icospheres.

This patch also optimize the case when pointcloud has uniform radius.
However we should premultiply the radius prop by the default radius
beforehand to avoid a multiplication on CPU.

Using geometry instead of pseudo raytraced spheres is more scalable as
we can render as low as 1 or 2 triangle to a full half sphere and can
integrate easily in the render pipeline using a low amount of code.

Fix T78747: Fix mesh boundary detection and automasking

This issue was produced by a hack in the sculpt mode code from 2.80
when the sculpt API for connectivity info was not available.
The smooth brush was the only brush that needed connectivity info,
so there were 3 different smooth functions with the connectivity
queries implemented for dyntopo, meshes and grids. The mesh version
of smoothing was checking the number of connected faces to a vertex
to mask the mesh boundaries, which was not covering all cases and
was hardcoded in the smooth function itself.

This patch removes all those legacy functions and unifies all
smooth functions into a single one using the new API and the
automasking system. In order to achieve this, there were needed
some extra changes:

- The smooth brush now does not automasks the boundaries by default,
so its default preset needs to be updated to enable automasking

- The mesh boundary info is extracted once and cached in a
bitmap, similar to the disconnected elements IDs. This makes
boundary detection work as expected in all cases, solving a lot
of known issues with the smooth brush. In multires, this info is
extracted and cached only at the base mesh level, so it is much
more memory efficient than the previous automasking system.

- In order to keep the brushes responsive as they were before,
the automasking system can now skip creating the cache when it
is not needed for the requested options. This means that for
high poly meshes and simple automasking options the brushes
won't lag on start.

Python API: new RNA property `Screen.is_scrubbing`

This commit adds a new read-only boolean property `Screen.is_scrubbing`.

The related property `Screen.is_animation_playing` is set to `True` in
two situations:

- Animation is actually playing (for example via the Play button in the
timeline)
- The user is scrubbing through time (in the timeline, dopesheet, graph
editor, etc.)

To distinguish between these two cases, the property
`Screen.is_scrubbing` has been added.

Concept approved by @brecht.

VSE: Python API, allow creation of VSE Movie strips with missing file

It was already possible to create Sound and Image strips that reference
non-existing files. Now it's also possible to create Movie strips
referencing missing files via the Python API call
`Sequences.new_movie()`. In this case, the duration of the strip will be
set to 1 frame.

Note that this commit does not change anything in the user interface.

The Python API of the `MovieStrip` class is extended with a function
`reload_if_needed()`. This function only performs disk I/O if the movie
strip cannot produce frames, that is either when its filepath points to
a non-existing file, or when the video sequence editor has not been
shown yet (for example because it is in an inactive workspace).

This allows for the following:

```
import bpy

scene = bpy.context.scene
vse = scene.sequence_editor_create()

filepath = bpy.path.abspath('//demo.mkv')
strip = vse.sequences.new_movie("movie", filepath,
channel=2,
frame_start=47,
file_must_exist=False)
strip.frame_final_end = 327
```

This will create a new movie strip, even when `demo.mkv` does not exist.

Once `demo.mkv` has appeared at the expected location, either
`strip.reload_if_needed()` or `strip.filepath = strip.filepath` will
load it.

Performance tuning: early rejection of trivial intersections.

Starting to use floating filters to avoid expensive gmp operations
when possible. These changes speed up the sphere-sphere test with
n=64 to 5s (now 17 times slower than BMesh on this test, down from
100 times slower. But answer is correct.
Also make format.

Reverse the operand order for Difference to match old boolean.

Hooked up new boolean to boolean modifier.

Comment out an assert prevents running profiler on Mac.

Not sure why this assert is not known to the compiler used
when profiling.

Speedup, using BVH tree to limit number of tri-tri intersect tests.

Intersection of my spheresphere test with n=16 (two uvspheres
with 16 rings and 32 segments overlapping), time went from
12.8 seconds to 2.3 seconds on my Mac. The n=32 test went from
195.1s to 8.9s.

Add a mesh intersect sphere-sphere test for performance tuning.

Fix a test that needs a new kind of initializer.

Particles: initial support for forces in simulation node trees

The force node can now be used to control the behavior of particles.
Forces can access particles attributes. Currently, there are three attributes:
`Position` (vector), `Velocity` (vector) and `ID` (integer).

Supported nodes are: Math, Vector Math, Separate Vector, Combine Vector and Value.

Next, I'll have to split `simulation.cc` into multiple files and move
some stuff out of blenkernel into another folder.

Cycles: support OpenImageDenoise in final renders

Performance is not great currently due to the API not seeming to support
efficient denoising of multiple tiles at the same time. So in many cases
only one or a few threads will actually be denoising at the same time.

In renders with many samples this is not a big problem, but for faster
renders it's a signficant overhead.

We should try to optimize this still, possibly by batching denoising of
a bigger neighborhood of multiple tiles at once.

Fix T78579: Proxy produces wrong preview when using Offset or Crop

Make sure that proxy and original images are scaled to same size before
applying offset or crop.

During testing, I discovered, that raw cache will lose information whether
this image was proxy or not. Because of this, proxy images will not create
this cache type. It would be fairly easy to implement this functionality for
cache, but I have decided to not do it now, because I did not want to pass yet
another mostly hard-coded bool flag to cache system. Since image is proxy, it
should be fast to read anyway.

In case of using offset property, code was modified to make sure we scale
image only once. I also tried to make code more readable and streamlined and
cleaned up surrounding functions a bit.

Fix repeated Face Sets IDs when joining meshes

As Face Sets IDs start from 0 and increase by 1 each time a new face set
is created in a mesh, when joining multiple meshes it could happen that
the same ID is used by several unrelated areas in multiple objects. This
checks the Face Sets IDs when joining meshes and ensures that they are
not repeated between different objects when joining them, so in the
resulting mesh all previous face sets will have different IDs.

Implement T77959: Never duplicate linked data during deep-copy.

Note that this behavior is enforced on user level for now, but on code
side it is controlled with a flag, which should make it easy to refine
that behavior if needed.

Only exception is when we duplicate a linked ID directly (then we assume
user wants a local deep-copy of that linked data, and we always also
duplicate linked sub-data-blocks).

Note that this commit also slightly refactor the handling of actions of
animdata, by simplifying `BKE_animdata_copy_id_action()` and adding an
explicit new `BKE_animdata_duplicate_id_action()` to be used during ID
duplication (deep copy).

This also allows us to get rid of the special case for liboverrides.

This uses the BKE_subdiv_ccg_coarse_mesh_adjacency_info_get function to get the vertex indicies in the base mesh from multires. This way the API functions can get topology or face set information directly from it. In the future, these vertex indices can be used to get any other information from the base mesh from multires, like seams, sharp edges, disconnected elements IDs...

EEVEE: Implement the missing Sky texture

I'm not sure if the Sky was deliberately left out or was just waiting for a
better moment, but so many I was disappointed that Sky in EEVEE is
completely white.

There are already 2 implementations (osl and gpu) so this is the third one.
Looking at other cases it seems that we are not supposed to share sources
between cycles and the rest? So the new util_sky_model files are just
copies of what is already in cycles, except that the data file uses the RGB
variant of the Hosek/Wilkie model, because we output RGB anyway (but can be
easily changed to XYZ if desired - the results are nearly identical).
I am not sure if it is okay to pass 3*9 float values as 3 mat4 uniforms (I
wanted to use mat3 but it does not work).
Also, should I cache the sky model data between renders if the parameters
do not change?

Apply Modifier: support applying as shape key and keeping the modifier.

This can be useful to save the result of a cloth simulation as a
shape key without destroying the simulation, so it's possible to
e.g. re-run it to get other shapes, or simply use the new shape
key to start the simulation already in a draped state.

It also makes sense to allow applying as shape key even when the
mesh is shared, because the operation itself just adds a shape
key. To support this, split the apply operator into Apply and
Apply As Shapekey so that they can have different poll callbacks.

poor numerical performance for almost parallel angles.

As a result, the generally tiny difference between floating point computation
between CPU and GPU was enough to make the sun vanish at different radii,
causing different results.

Optimization: use `BLI_bvhtree_intersect_plane` to detect faces that will be affected by the knife tool

The knife code currently calls the `BLI_bvhtree_overlap` function that
tests the overlap between the mesh tree and an AABB that encompasses the
points projected in the clip_start, clip_end and or clip_planes of the
view.

This resulted in many false positives since the AABB is very large.
Often all the triangles "overlapped".

The solution was to create a new function that actually tests the
intersection of AABB with a plane.

Even not considering the clip_planes of the view, this solution is more
appropriate than using overlap.

This patch adds support for the curve primitive from OptiX to Cycles. It's currently hidden
behind a debug option, since there can be some slight rendering differences still (because no
backface culling is performed and something seems off with endcaps). The curve primitive
was added with the OptiX 7.1 SDK and requires a r450 driver or newer, so this also updates
the codebase to be able to build with the new SDK.

IO: Reversed persistent ID order in exports to Alembic and USD

Each duplicated (a.k.a. instanced) object has a Persistent ID, which
identifies a dupli within the context of its duplicator. This ID
consists of several numbers when there are nested duplis (for example a
mesh instancing empties on its vertices, where each empty instances a
collection). When exporting to Alembic/USD, these are used to uniquely
name the duplicated objects in the export.

This commit reverses the order of the persistent ID numbers, so that the
first number identifies the first level of recursion. This produces
trees like this:

ABC
`--Triangle
|--Triangle
|--Empty-1
| `--Pole-1-0
| |--Pole
| `--Block-1-1
| `--Block
|--Empty
| `--Pole-0
| |--Pole
| `--Block-1
| `--Block
|--Empty-2
| `--Pole-2-0
| |--Pole
| `--Block-2-1
| `--Block
`--Empty-0
`--Pole-0-0
|--Pole
`--Block-0-1
`--Block

It is now clearer that `Pole-2-0` and `Block-2-1` are instanced by
`Empty-2`. Before this commit, they would have been named `Pole-0-2` and
`Block-1-2`.

IO: Fix bug exporting dupli parent/child relations

Exporting a scene to USD or Alembic would fail when there are multiple
duplicates of parent & child objects, duplicated by the same object. For
example, this happens when such a hierarchy of objects is contained in a
collection, and that collection is instanced multiple times by mesh
vertices. The problem here is that the 'parent' pointer of each
duplicated object points to the real parent; Blender would not figure
out properly which duplicated parent should be used.

This is now resolved by keeping track of the persistent ID of each
duplicated instance, which makes it possible to reconstruct the
parent-child relations of duplicated objects. This does use up some
memory for each dupli, so it could be heavy to export a Spring scene
(with all the pebbles and leaves), but it's only a small addition on top
of the USD/Alembic writer objects that have to be created anyway. At
least with this patch, they're created correctly.

Code-wise, the following changes are made:

- The export graph (that maps export parent to its export children) used
to have as its key (Object, Duplicator). This is insufficient to
correctly distinguish between multiple duplis of the same object by
the same duplicator, so this is now extended to (Object, Duplicator,
Persistent ID). To make this possible, new classes `ObjectIdentifier`
and `PersistentID` are introduced.
- Finding the parent of a duplicated object is done via its persistent
ID. In Python notation, the code first tries to find the parent
instance where `child_persistent_id[1:] == parent_persistent_id[1:]`.
If that fails, the dupli with persistent ID `child_persistent_id[1:]`
is used as parent.

BLI: improve exception safety of memory utils

Even if we do not use exception in many places in Blender, our core C++ library
should become exception safe. Otherwise, we don't even have the option
to work with exceptions if we decide to do so.

BLI: refactor how buffers for small object optimization are stored

Previously, there was an error when operator-> was returning an
invalid type. See error C2839.

UV: add rip tool

New rip tool matching edit-mesh rip functionality.

Useful as disconnecting UV's, especially for loops is inconvenient
without this.

This uses 'V' to rip, changing stitch to 'Alt-V'.

GPU: Remove local shaders workaround for Intel/Windows

It has been tested that local shaders workaround isn't needed for the
latest Windows/Intel 6xx GPU's.

Currently the local shaders workaround doesn't work anymore during the
investigation it was detected that the intel drivers didn't need it
anymore.

Local shaders should still be fixed as it is also used for some legacy
iGPU's. The current work around crashes when doing preview renders in
EEVEE as the default materials aren't available but for the work around
they should. (See T77346 for more information)

Revert "BLI: refactor how buffers for small object optimization are stored"

This reverts commit 5d79f9f276b4b3e6289308c534c58e7ee3bb5e2d.

This was introducing build errors in windows. Need a bit more time to check it.

GPencil: Cleanup some comments typo

comm

A large refactor of newboolean to perpare for performance tuning.

Many changes aimed at, broadly, more sharing and less copying;
and having coordinates stored simultaneously in double and multiprecision,
as that will be needed for floating predicate filtering.
Biggest change is that faces are represented by arrays of pointers to
Verts instead of as integer indices into a vertex array.

Got rid of clang-tidy errors.

Fixed violations of new Blender C++ style rules.

Merge branch 'master' into newboolean

Added two more tests for boolean.

Made two functions static to silence a warning.

First coplanar boolean test passes.

Implemented sorting of coplanar triangles.
Also, make format.
