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).

It mainly contains properties that affect the final render/viewport and it's handy
to see if it's enabled or not while going through the render settings.
Only affects internal API, bout could be exposed as an option for
the compatibility reasons with other software.
Is a part of some ongoing development of multires, but might or
might not be used.
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.

This allows for extra output passes that encode automatic object and material masks
for the entire scene. It is an implementation of the Cryptomatte standard as
introduced by Psyop. A good future extension would be to add a manifest to the
export and to do plenty of testing to ensure that it is fully compatible with other
renderers and compositing programs that use Cryptomatte.
Internally, it adds the ability for Cycles to have several passes of the same type
that are distinguished by their name.

Apparently quite a few users would like to have the noisy pass available when using the denoiser, and since it's being generated anyways we might as well expose it by default.

This function is supposed to prevent the black artifacts caused by strong normal- or bumpmapping, but failed in some cases.
Now the code correctly handles all test files and previous issues I am aware of and also has extensive comments describing
the algorithm and the math behind it.
Basically, the main problem was that there can be multiple valid solutions that fulfil the reflection angle criterium,
but I had assumed that only one would exist and therefore simply picked the first solution with a positive term in srqt().
Now, the code uses additional validity checks and a simple heuristic to pick the best valid solution.
Additionally, the code messed up very shallow reflections even if the normal map strength was zero due to the constant
limit for the outgoing ray angle, which caused shallow incoming rays to fail the initial test even when reflected directly
on Ng. Now, the code accounts for this by reducing the threshold in the case of a shallow incoming ray, ensuring that at
least N=Ng is always a valid solution.
