* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon.
* For macOS sse2neon.h is included as part of the precompiled libraries.
* For Linux it is enabled if the sse2neon.h header file is detected. However
this library does not have official releases and is not shipped with any Linux
distribution, so manual installation and configuration is required to get this
working.

This required using a fork of Embree, newer LLVM version, unreleased ISPC
version and sse2neon directly from Git. Hopefully over time all the required
changes end up in official releases. For now we deviate from other platforms.

Building NumPy from source with default options of builder
causes it to link against Accelerate framework which is buggy and
raises a warning mentioned in [2].
"RankWarning: Polyfit may be poorly conditioned"
Accelerate is deprecated with NumPy 1.20+.[1]
So either we build OpenBLAS in dependencies also and set appropriate
env variables suggested in [1] while building NumPy for it to find
OpenBLAS. Or download NumPy wheel from pip and never allow pip to
build NumPy from source while installing.
After this change, pip wheels are used for NumPy for macOS with x86_64.

USD version 21.02 includes two of the changes Blender used to patch in,
which have now been removed from `usd.diff`. Unfortunately 21.02
introduces another issue where LZ4 symbols are accidentally exported,
causing linker errors. Fortunately these symbols are only used for
resting, so I added a patch hunk that simply removes their `extern "C"`
declaration.
The LZ4 linker issue has been reported upstream at

the Python 3.9 update will forcibly bump us to 8.1+ anyhow this is not
an issue.

Build System
============
This is an API breaking new version, and the updated code only builds with
OpenColorIO 2.0 and later. Adding backwards compatibility was too complicated.
* Tinyxml was replaced with Expat, adding a new dependency.
* Yaml-cpp is now built as a dependency on Unix, as was already done on Windows.
* Removed currently unused LCMS code.
* Pystring remains built as part of OCIO itself, since it has no good build system.
* Linux and macOS check for the OpenColorIO verison, and disable it if too old.
Ref D10270
Processors and Transforms
=========================
CPU processors now need to be created to do CPU processing. These are cached
internally, but the cache lookup is not fast enough to execute per pixel or
texture sample, so for performance these are now also exposed in the C API.
The C API for transforms will no longer be needed afer all changes, so remove
it to simplify the API and fallback implementation.
Ref D10271
Display Transforms
==================
Needs a bit more manual work constructing the transform. LegacyViewingPipeline
could also have been used, but isn't really any simpler and since it's legacy
we better not rely on it.
We moved more logic into the opencolorio module, to simplify the API. There is
no need to wrap a dozen functions just to be able to do this in C rather than C++.
It's also tightly coupled to the GPU shader logic, and so should be in the same
module.
Ref D10271
GPU Display Shader
==================
To avoid baking exposure and gamma into the GLSL shader and requiring slow
recompiles when tweaking, we manually apply them in the shader. This leads
to some logic duplicaton between the CPU and GPU display processor, but it
seems unavoidable.
Caching was also changed. Previously this was done both on the imbuf and
opencolorio module levels. Now it's all done in the opencolorio module by
simply matching color space names. We no longer use cacheIDs from OpenColorIO
since computing them is expensive, and they are unlikely to match now that
more is baked into the shader code.
Shaders can now use multiple 2D textures, 3D textures and uniforms, rather
than a single 3D texture. So allocating and binding those adds some code.
Color space conversions for blending with overlays is now hardcoded in the
shader. This was using harcoded numbers anyway, if this every becomes a
general OpenColorIO transform it can be changed, but for now there is no
point to add code complexity.
Ref D10273
CIE XYZ
=======
We need standard CIE XYZ values for rendering effects like blackbody emission.
The relation to the scene linear role is based on OpenColorIO configuration.
In OpenColorIO 2.0 configs roles can no longer have the same name as color
spaces, which means our XYZ role and colorspace in the configuration give an
error.
Instead use the new standard aces_interchange role, which relates scene linear
to a known scene referred color space. Compatibility with the old XYZ role is
preserved, if the configuration file has no conflicting names.
Also includes a non-functional change to the configuraton file to use an
XYZ-to-ACES matrix instead of REC709-to-ACES, makes debugging a little easier
since the matrix is the same one we have in the code now and that is also
found easily in the ACES specs.

Create zero-byte manual page files `nasm.1` and `ndisasm.1` such that
nasm's `make install` step succeeds.
Installing nasm requires that its manual pages are built. This requires
local packages `asciidoc` and `xmlto` to be installed.
Not only does `asciidoc` pull in 110 MB of packages (itself +
dependencies), there is also no need for these manual pages. Nasm is
just used for building other dependencies, and not even part of our
precompiled libraries in SVN.

*Fixes:
** Dependencies between libraries are better handled (would fail
previously in some cases when the lib was also available as package).
** Dependency of Boost over Python is now taken into account.
** Fix CMake flags to use local own built boost.
** Fix building numpy.
*Changes:
** We now use pip for all python modules (including numpy).
** Added all missing python modules (requests etc.).
*Updates:
**USD: 20.08, Due to build failing with 20.05 (missing include).
Good news is, this version support LLVM 11.

Standard wiki build instructions for building Blender on macOS can now be used
on Macs with ARM processors.
This contains all libraries except for Embree and OpenImageDenoise, so Cycles
performance does not yet have full performance and features in this build. An
x86-64 build is likely to still render faster than arm64 until Embree is added.
Uses the new lib/darwin_arm64 folder. For simplicity and to keep download size
under control, both for end users and builders, we are not planning to ship
universal binaries. So this is a separate folder from lib/darwin.

Build sqlite without `tcl` support, as it's causes an error on
installation when `tcl` is installed into the systems `/usr/lib/` and
install isn't running as root.
This could be resolves by adding `tcl` as a dependency
however it's not needed for Python's sqlite integration.
Linux distributions (Debian & Arch at least) split this off
into a separate package (which Python doesn't depend on),
so there is no need for Blender to include sqlite's `tcl`
integration either.
