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.

all the changes since intermediate changes would often fail building or tests.

* 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run queued and outdated tests equivalent to the old "run" command.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.
* Allow specifying a folder and automatically setting the proper executable
name depending on the operating system
* Use executables from configs for listing devices instead of a blender
command being available
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.
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.

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.
