This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

* Make "run" command (re-)run all tests, add "update" command to only
run queued and outdated tests equivalent to the old "run" command.
* Support specifying environment variables for revisions, to easily
compare multiple parameter values.
* Better sorting of revisions in graph.
The storage of IDProperty UI data (min, max, default value, etc) is
quite complicated. For every property, retrieving a single one of these
values involves three string lookups. First for the "_RNA_UI" group
property, then another for a group with the property's name, then for
the data value name. Not only is this inefficient, it's hard to reason
about, unintuitive, and not at all self-explanatory.
This commit replaces that system with a UI data struct directly in the
IDProperty. If it's not used, the only cost is of a NULL pointer. Beyond
storing the description, name, and RNA subtype, derived structs are used
to store type specific UI data like min and max.
Note that this means that addons using (abusing) the `_RNA_UI` custom
property will have to be changed. A few places in the addons repository
will be changed after this commit with D9919.
**Before**
Before, first the _RNA_UI subgroup is retrieved the _RNA_UI group,
then the subgroup for the original property, then specific UI data
is accessed like any other IDProperty.
```
prop = rna_idprop_ui_prop_get(idproperties_owner, "prop_name", create=True)
prop["min"] = 1.0
```
**After**
After, the `id_properties_ui` function for RNA structs returns a python
object specifically for managing an IDProperty's UI data.
```
ui_data = idproperties_owner.id_properties_ui("prop_name")
ui_data.update(min=1.0)
```
In addition to `update`, there are now other functions:
- `as_dict`: Returns a dictionary of the property's UI data.
- `clear`: Removes the property's UI data.
- `update_from`: Copy UI data between properties,
even if they have different owners.

Rename new API function introduced in recent rB3b0fab6dfaa0 to match our
convention to put the action (verb) at the end of names:
`operations_update`.
Sorry for not catching that during review.
The update_operations function will update the override structure of the
local object. When working with overrides the override structure is only
updated when the work-file is stored. When using scripts you might want
to enforce the update of override properties and operations.
This function removes a hack on the test cases.

The real fix here is to use some kind of relative error in `customdata_compare`
instead of the absolute error used now. If vertex coordinates get larger in magnitude,
the allowed error should increase as well.
- Multi-dimensional boolean, int and float vector types are supported.
- A sequence of int's for the "size" is used to declare dimensions.
- Nested sequences are required for default arguments.
Now it's possible to define matrix properties, for e.g:
bpy.props.FloatVectorProperty(size=(4, 4), subtype='MATRIX')
Runs tests based on blend files with minimum python interaction.
Developed as part of GSoC 2021 - Regression Testing of Geometry Nodes.
Earlier, tests were built from scratch by adding a modifier/operation
from the Python API.
Now, tests can also be created inside blender and are compared using
Python script.
Features: Automatically adding expected object if it doesn't exist.
This patch adds tests for the following Geometry Nodes category:
* Curves
* Geometry
* Mesh
* Points
The implemented UML diagram for refactoring of mesh test framework.
{F10225906}
Technical Changes:
SpecMeshTest: It adds the modifier/operation based on the Spec provided.
BlendFileTest: It applies already existing modifier/operation from the blend file.
Test folders hierarchy with tests. This folder should be extracted to `lib\tests\modeling`
{F10240651}
Note: The `geometry_nodes` folder might lie under another `geometry_nodes` folder while extracting, please double check. Use the inner-most one.
The hierarchy should be:
-`lib\tests\modeling\geometry_nodes\mesh`
-`lib\tests\modeling\geometry_nodes\points`
and so on.
* From `ctest` the tests should be run as `ctest -R geo_node -C [Configuration]` on Windows.
* Each single test can be run with its entire name e..g `ctest -R geo_node_geometry_join_geometry`.(just an example). Run `ctest -N -R geo_node` to see all tests.
* From blender, the tests can be run `blender -b path\to\blend\file --python path\to\geo_node_test.py`

The general graphing mechanism will create one graph for each output
variable. So it's not limited to time and memory, but that is what the
Cycles tests now output.
When introduced in {rB61050f75b13e} this was actually working (meaning
it checked the Outliner OB_RESTRICT_RENDER flag and skipped the object if
desired).
Behavior has since then been commented in rBae6e9401abb7 and apparently
refactored out in rB2917df21adc8.
If checked, it seemed to be working (objects marked non-renderable in
the Outliner were pruned from the export), however unchecking that
option did not include them in the export.
Now it changed - for the worse if you like - in rBa95f86359673 which
made it so if "Renderable Objects" only is checked, it will still export
objects invisible in renders. So since we now have the non-functional
option with a broken/misleading default, it is better to just remove it
entirely.
In fact it has been superseeded by the "Visible Objects" option (this
does the same thing: depsgraph is evaluated in render mode) and as a
second step (and to make this even clearer) a choice whether
Render or Viewport evaluation is used can be added (just like the USD
exporter has). When that choice is explicit, it's also clear which
visibility actually matters.
This is breaking API usage, should be in release notes.

These are scripts for benchmarking Blender features on real-world .blend
files. They were originally written for benchmarking Cycles performance, and
were made generic so they can be used for more Blender features.
The benchmarks can be run locally by developers. But the plan is to also run
these as part of continuous integration to track performance over time.
Currently there are tests for Cycles rendering and .blend file loading.
Documentation:
https://wiki.blender.org/wiki/Tools/Tests/Performance
Main features:
* User created configurations to quickly run, re-run and analyze a selected
subset of tests.
* Supports both benchmarking with existing builds, and automatic building of
specified git commits, tags and branches.
* Generate HTML page with bar and line graphs from test results.
* Controlled using simple command line tool.
* For writing tests, convenient abstraction to run a Python function in Blender
with arguments and return value.

This constraint can be naturally viewed as a prototype for a future
4x4 matrix math node (or subset thereof), since its basic semantics
already is matrix assignment. Thus it makes sense to add math options
to this constraint to increase flexibility in the meantime.
This patch adds support for several operations that would be useful:
- An option to remove shear in the incoming target matrix.
Shear is known to cause issues for various mathematical operations,
so an option to remove it at key points is useful.
Constraints based on Euler like Copy Rotation and Limit Rotation
already have always enabled shear removal built in, because their
math doesn't work correctly with shear.
In the future node system shear removal would be a separate node
(and currently Limit Rotation can be used as a Remove Shear constraint).
However removing shear from the result of the target space conversion
before mixing (similar to Copy Rotation) has to be built into
Copy Transforms itself as an option.
- More ways to combine the target and owner matrices.
Similar to multiple Inherit Scale modes for parenting, there are
multiple ways one may want to combine matrices based on context.
This implements 3 variants for each of the Before/After modes
(one of them already existing).
- Full implements regular matrix multiplication as the most basic
option. The downside is the risk of creating shear.
- Aligned emulates the 'anti-shear' Aligned Inherit Scale mode,
and basically uses Full for location, and Split for rotation/scale.
(This choice already existed.)
- Split Channels combines location, rotation and scale separately.
Looking at D7547 there is demand for Split Channels in some cases,
so I think it makes sense to include it in Copy Transforms too, so that
the Mix menu items can be identical for it and the Action constraint.

A utility that supports passing in actions as command line arguments for
writing reproducible interactions, benchmarking, profiling and testing.
Unlike regular scripts this is able to control model operators usefully.
Typical ways of controlling Blender using this utility are via
operator id's, menu search and explicit events.
Others methods can be added as needed.
See the doc-string for example usage.
Combining location, rotation and scale channels into a matrix is
a standard task, so while it is easily accomplished by constructing
and multiplying 3 matrices, having a standard utility allows for
more clear code.
The new constructor builds a 4x4 matrix from separate location,
rotation and scale values. Rotation can be represented as a 3x3
Matrix, Quaternion or Euler value, while the other two inputs
are vectors. Unneeded inputs can be replaced with None.
