3D image dimensions should be updated on the Cycles side before loading
the smoke data.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

The integrator maximum number of closures was not set properly for the CPU/mega
kernels to match the actual available memory. Before relatively recent code
refactoring we did not use this value in those kernels so it worked fine.

Refactors Cycles mesh export a bit to avoid unnecessary copies and to be in
sync with the Blender baker.

In some cases it would load adaptive kernels or even start rendering
twice because the first time the scene was not fully synced yet.

There are some changes in API of OpenImageIO, but those are quite
simple to keep working with older and newer library versions.

It used to be used for some sort of ignoring automatically
generated bump nodes. But nowadays it causes one of the shaders
in Classroom demo file to be compiled wrong.

Multi-device was not passing along profiler to the CPU.

various parts of the CPU kernel
This commit adds a sample-based profiler that runs during CPU rendering and collects statistics on time spent in different parts of the kernel (ray intersection, shader evaluation etc.) as well as time spent per material and object.
The results are currently not exposed in the user interface or per Python yet, to see the stats on the console pass the "--cycles-print-stats" argument to Cycles (e.g. "./blender -- --cycles-print-stats").
Unfortunately, there is no clear way to extend this functionality to CUDA or OpenCL, so it is CPU-only for now.

Doesn't mean much for Cycles itself, but allows to have nice logs
and progress reports without access of original scene.

It was used in like 95% of places.
|
|
Those are similar but different types, no reason to keep
their definitions in a single file.
|
|
It is supposed to be two spaces before comment stating which if
else/endif statements corresponds to. Was mainly violated in the
header guards.
|
|
Now it shows more compact info below the view/object name. Render time and
memory usage is left out, as in most cases this is not so important. These
could be added back optionally if needed.

Note that this is turned off by default and must be enabled at build time with the CMake WITH_CYCLES_EMBREE flag.
Embree must be built as a static library with ray masking turned on, the `make deps` scripts have been updated accordingly.
There, Embree is off by default too and must be enabled with the WITH_EMBREE flag.
Using Embree allows for much faster rendering of deformation motion blur while reducing the memory footprint.
TODO: GPU implementation, deduplication of data, leveraging more of Embrees features (e.g. tessellation cache).

Mainly useful for debugging. Previously, when AVX2 was disabled
in the debug panel but BVH layout was kept on BVH8 nothing was
rendered.
Needed to make it so supported BVH layout mask for devices is
queried in "dynamic", so it is possible to use DebugFlags there.

Needed for the animation denoiser since the denoising filter is done separately there.
