Currently when importing a USD file, some of the camera properties are
ignored, or the units are not converted correctly from USD world units.
On import we currently set the focal length, but not the camera sensor
size (horizontal and vertical aperture), so the camera field of view
is wrong. The sensor size information is in the USD file, but is ignored
for perspective cameras.
USD uses "tenth of a world unit" scale for some physical camera properties
like focal length and aperture.
https://graphics.pixar.com/usd/release/api/class_usd_geom_camera.html#UsdGeom_CameraUnits
I have added the UsdStage's metersPerUnit parameter to the ImportSettings
so the camera can do the required conversion on import. This will convert from
the USD file's world units to millimeters for Blender's camera settings.

This adds a new `Interpolate Curves` node. It allows generating new curves
between a set of existing guide curves. This is essential for procedural hair.
Usage:
- One has to provide a set of guide curves and a set of root positions for
the generated curves. New curves are created starting from these root
positions. The N closest guide curves are used for the interpolation.
- An additional up vector can be provided for every guide curve and
root position. This is typically a surface normal or nothing. This allows
generating child curves that are properly oriented based on the
surface orientation.
- Sometimes a point should only be interpolated using a subset of the
guides. This can be achieved using the `Guide Group ID` and
`Point Group ID` inputs. The curve generated at a specific point will
only take the guides with the same id into account. This allows e.g.
for hair parting.
- The `Max Neighbors` input limits how many guide curves are taken
into account for every interpolated curve.

This makes it convenient to build blender without referencing
pre-compiled libraries which don't always work on newer Linux systems.
Previously I had to rename ../lib while creating the CMakeCache.txt
to ensure my systems libraries would be used.
This change ensures LIBDIR is undefined when WITH_LIBS_PRECOMPILED is
disabled, so any accidental use warns with CMake's `--warn-unused-vars`
argument is given.
These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).
This patch implements the matrix types (i.e:float4x4) by making heavy
usage of templating. All matrix functions are now outside of the vector
classes (inside the blender::math namespace) and are not vector size
dependent for the most part.
###Motivations
The goal/motivations of this rewrite are the same as the Vector C++ API (D13791):
- Template everything for making it work with any types and avoid code duplication.
- Use functional style instead of Object Oriented function call to allow a simple compatibility layer with GLSL syntax (see T103026 for more details).
- Allow most convenient constructor syntax and accessors (array subscript `matrix[c][r]`, or component alias `matrix.y.z`).
- Make it cover all features the current C API supports for adoption.
- Keep compilation time and debug performance somehow acceptable.
###Consideration:
- The new `MatView` class can be generated by `my_float.view<NumCol, NumRow, StartCol, StartRow>()` (with the last 2 being optionnal). This one allows modifying parts of the source matrix in place. It isn't pretty and duplicates a lot of code, but it is needed mainly to replace `normalize_m4`. At least I think it is a good starting point that can refined further.
- An exhaustive list of missing `BLI_math_matrix.h` functions from the new API can be found here P3373.
- This adds new Rotation types in order to have a clean API. This will be extended when we port the full Rotation API. The types are made so that they don't allow implicit down-casting to their vector representation.
- Some functions make direct use of the Eigen library, bypassing the Eigen C API defined in `intern/eigen`. Its use is contained inside `math_matrix.cc`. There is conflicting opinion wether we should use it more so I contained its usage to almost the tasks as in the C API for now.

Ideally, we would also get variance information out of the test, but that
seems a bit more complex to implement. For now just run the test a couple
of times and average the timings.
The test now runs between 5 and 100 times, depending on how long it
to run the test once.
I noticed that sometimes the geometry nodes benchmark would not work
if there were some left-over debug prints in the code. The reason it did
not work was because the prints were mixed with the test output print.
I also tried using explicit flusing and `atexit` for printing the test output,
but that didn't solve it. Just printing additional newlines to better separate
the test output from other printed output helped though.
These are meant to be regression tests, not fuzz tests. The "random"
shuffling made debugging quite annoying, even though the random order
was the same every time. Instead, hard-code the two lists to make
things more obvious. The resulting list doesn't make much sense
(for example, the multires modifier has to be first in the stack),
but for now avoid changing things further.
Also remove some comments that weren't helpful.
Such IDs are tagged with the new `LIB_TAG_RUNTIME`. They are essentially
like any other regular ID, except that they do not get written in .blend
files. They also do not make their linked data usages directly linked.
They do be written in undo steps however.
This tag should be ignored in any non-Main IDs (e.g. evaluated data,
`NO_MAIN`, etc.).
This commit also adds a new RNA ID property, `is_runtime`. This is not a
direct mapping to the DNA tag, as a non-main ID will also return True,
and the property is only editable for Main IDs.
Some basic testing for expected behavior of that new tag was also added
to `blendfile_io` py unittest.

rB133dde41bb5b changed handling of (in)directly linked status handling
for IDs, now IDs that are not directly linked get proper status and
handling on file save. this broke parts of the `pyapi_idprop_datablock`
tests.
This commit essentially ensures before writing .blend file that only
actualy locally used linked IDs are tagged as `LIB_TAG_EXTERN` (and
therefore get a reference stored in the .blend file).
Previously, a linked ID tagged as directly linked would never get back
to the indirectly linked status. Consequence was a lot of 'needless'
references to linked data in .blend files.
This commit also introduces a new flag for lib_query ID usage types,
`IDWALK_CB_DIRECT_WEAK_LINK`, used currently for base's Object
pointer, and for LayerCollection's Collection pointer.
NOTE: A side-effect of this patch is that even IDs explicitely linked by
the user won't be kept anymore when writing files, i.e. they will not be
there anymore after a file reload, if they are not actually used.
Overhead of new process is below 0.1% in whole file saving process in

Rewrite the edge split code to operate directly on Mesh instead
of BMesh. This allows for the use of multi-threading and makes
the node around 2 times faster. Around 15% of the time is spent
just on the creation of the topology maps, so these being cached
on the mesh could cause an even greater speedup. The new node
gave identical results compared to the BMesh version on all the
meshes I tested it on (up to permutation of the indices).
Here are some of the results on a few simple test cases:
(Intel i7-7700HQ (8 cores) @ 2.800GHz , with 50% of edges selected)
| | 370x370 UV Sphere | 400x400 Grid | Suzanne 4 subdiv levels |

As part of T95966, this patch moves loose edge information out of the
flag on each edge and into a new lazily calculated cache in mesh
runtime data. The number of loose edges is also cached, so further
processing can be skipped completely when there are no loose edges.
Previously the `ME_LOOSEEDGE` flag was updated on a "best effort"
basis. In order to be sure that it was correct, you had to be sure
to call `BKE_mesh_calc_edges_loose` first. Now the loose edge tag
is always correct. It also doesn't have to be calculated eagerly
in various places like the screw modifier where the complexity
wasn't worth the theoretical performance benefit.
The patch also adds a function to eagerly set the number of loose
edges to zero to avoid building the cache. This is used by various
primitive nodes, with the goal of improving drawing performance.
This results in a few ms shaved off extracting draw data for some
large meshes in my tests.
In the Python API, `MeshEdge.is_loose` is no longer editable.
No built-in addons set the value anyway. The upside is that
addons can be sure the data is correct based on the mesh.
**Tests**
There is one test failure in the Python OBJ exporter: `export_obj_cube`
that happens because of existing incorrect versioning. Opening the
file in master, all the edges were set to "loose", which is fixed
by this patch.

Basic test for `quads_convert_to_tris`
As the operator name in blender is different from the bpy name, the operator
name in blender was opted in terms of the blend file collection name as well
as the test name. This was done so that new developers in the future can
easier understand which operator this corresponds to. Although it might be
better to change this to the bpy name so as to be consistent with the rest
of the codebase.

This commit contains the CTest integration.
Starting with the very simple tests for the recent fixes in the
io_corve_svg addon which were related on closing path.
The idea is to use same framework as what we use for render tests
to make it easily visible what aspect of SVG changed or broke.
In order to achieve this both .blend and .svg files are used.
The .svg file defines the exact subject of test, and the .blend
file defines camera, and possibly material.
The longer term idea is to have a number of atomic tests for a
specific SVG features to help isolating problematic areas, as
well as a more comprehensive tests to perform QA.
In practice this didn't cause problems, but accessing scripts via
bpy.utils.resource_path('USER') ignores the BLENDER_USER_SCRIPTS
environment variable.
Add new cavity automasking mode based on local mesh
curvature. Cavity masking is a great way to quickly add
detail in crevices and the like. It's meant to be used

The old "dirty mask" operator has been replace with a new
"mask from cavity" operator that shares the same code with
cavity automasking.
Differences from the sculpt-dev implementation:
* It uses the word "cavity." When I first implemented
this I wasn't aware
this feature existed in other software (and other
paint modes in Blender),
and for reasons that escape me today I initially
decided to call it a concave or
concavity mask.
* The cavity factor works a bit differently. It's
no longer non-linear and functions as a simple
scale around 0.5f.
* Supports custom curves.
* Supports blurring.

This adds path guiding features into Cycles by integrating Intel's Open Path
Guiding Library. It can be enabled in the Sampling > Path Guiding panel in the
render properties.
This feature helps reduce noise in scenes where finding a path to light is
difficult for regular path tracing.
The current implementation supports guiding directional sampling decisions on
surfaces, when the material contains a least one diffuse component, and in
volumes with isotropic and anisotropic Henyey-Greenstein phase functions.
On surfaces, the guided sampling decision is proportional to the product of
the incident radiance and the normal-oriented cosine lobe and in volumes it
is proportional to the product of the incident radiance and the phase function.
The incident radiance field of a scene is learned and updated during rendering
after each per-frame rendering iteration/progression.
At the moment, path guiding is only supported by the CPU backend. Support for
GPU backends will be added in future versions of OpenPGL.
