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.

- Iterating now raises a run-time error if the property-group changes
size during iteration.
- IDPropertyGroup.iteritems() has been removed.
- IDPropertyGroup View & Iterator types have been added.
- Some set functionality from dict_keys/values/items aren't yet
supported (isdisjoint method and boolean set style operations).

This is functionality that isn't accessible via the user interface. The
API allows the creation and modification of an override template that
holds rules that needs to be checked when overriding the asset.
The API is setup that it cannot be changed after creation. Later on when
the system is more mature we will allow changing overrides operations.
NOTE: This is an experimental feature and should not be used in productions.

Added a first test case for review. This will be the base for future test cases.
The current API is sufficient for what is expected for such a low level API.
One concern is that you need to trigger a save in order to update the library overrides
structure. Not expected from TD/Dev point of view.
Test cases are very important when implementing restrictive mode as it is a second evaluation mode that
has impact on the (current) permissive mode.

This shows up various inconsistencies, including:
- Unused keymaps.
- Unknown/unused data in the keymap.
- Event arguments that don't make sense.
- Event values that don't match the event type
(tweak direction on keyboard event for example).

MeshTest now compares selection between evaluated mesh and expected mesh. This way, we can test more operators
such as `faces_select_linked_flat`
Note: selection comparison intentionally does not happen in BKE_mesh_cmp() on C side but rather on Python side, because
selection is independent of mesh generation.

Group all tests of a test suite into a single test command invocation.
This reduces the number of invocations by `ctest` by an order of
magnitude.
Since rB56aa5b0d8c6b663, `bin/tests/blender_test` was run for every
individual test. Having over a 1000 tests made testing slower than
necessary. Individual tests can still be run if desired by invocation of
`bin/tests/blender_test --gtest_filter=suitename.testname`.
NOTE: For this commit to have an immediate effect, it may be necessary
to remove the `tests` and `Testing` directories and some CMake files
from your build directory and rebuild. Run `ctest -N` to see the list of
tests; there should be less than 200.

When building opensubdiv with more aggressive optimization flags
(-march=native -02) the output meshes would differ a bit from what we
expected in the current automated modifier test file.
The differences in vertex position is within the 1e-6 range, which I
would call is acceptable for floats. In addition to this, all the
modifier test that tests the subdiv modifier in particular pass without
any modifications. I've updated two tests in the modifier test file and
script to make it pass (listed below).
Updated following test categories:
1. Decimate test
Here there was a subdiv modifier applied before the actual decimate
modifier. Because the decimate modifier creates a queue of potential
vertices it can remove, it is highly sensitive to even small changes as
it drastically changes in which order the vertices are decimated in.
As this test should only be testing the decimate modifier, I pre-applied
the subdiv modifier in the test file.
2. RandomCubeModifier
For these tests I removed the subdiv modifier as well. As with decimate,
a small change in vertex position here can lead to quite different
results.

This adds a basic set of tests for curve sampling and bevel generation.
At the moment there are basic test cases for bevels, caps, and the
filling of 2D curves, but more tests can be added in the future.
Curves are actually converted to "DispLists" for displaying them in the
viewport, so it's much simpler to rely on the mesh conversion operator
instead of building a new test framework for another data structure.
