Previously the window manager would receive the GHOST event and then query the
latest tablet data from the window to go along with it. If multiple events were
queued, it would then use too new tablet data for handling older events.
Fixes T62565: tablet pressure not working on macOS with some devices
Similar to the Microfacet Closures, the Principled BSDF Sheen closure is
added at a high weight but typically results in fairly low values.
Therefore, the default weight is a bad indicator of importance.
The fix here is the same as it was back then for Microfacets:
Compute an average weight using the normal as the half-vector
and use it to scale down the sample weight and the albedo channel.
In addition to drastically improving denoising of materials with
sheen when using the new Denoising node, this also can reduce noise
on such materials considerably.
This aligns with the VFX reference platform 2020 along with the decision
to stick to Python 3.7, see T68774.
Blosc was downgraded to 1.5 as recommended by the OpenVDB documentation.
IlmBase and OpenEXR are now built together with CMake rather separately
using autoconf.

Cache file loading for mesh and particle files now works through the direct update_structures functions. The final cache mode now also only bakes the most essential files and is therefore not resumable anymore.
This patch suppress the OSL warnings resulted from ambiguous calls
to the normalize function. This is done by casting to the vector
type before normalizing.

Embree's local intersection routine was not prepared
for local intersections without per-object BVH.
Now it should be able to handle any kind of local
intersection, such as AO, bevel and SSS.

It's not certain this fixes the issue since I can't reproduce the crash, but
the code was wrong in any case.
Thanks to Ray Molenkamp and Anonymous for finding this.
Seems that previous fix didn't work in all cases: Debian's build
environment didn't fully detect endianess, possibly due to typo,
possibly due to difference in various environments.
Using define magic from a more battle-tested project seems a safe
way to go.
There are more changes than just PPC since the upstream commit contains
full re-synchronization of all defines.
This commit updates numaapi to a latest library version from upstream.
Commit baeb11826b switched memory
allocation for the motion transform to use CUDA directly, instead of going
through abstractions. But no CUDA context was set active before those
were called, so the calls failed. This fixes that by binding a context beforehand.
Commit rB7e61e597253f3ca75f2fb86a57212ca750ffbbe8 broke viewport rendering when not displaying as halfs.
This fixes that by actually using the `scale` parameter that is passed into `film_map` and also de-duplicates code around it.

The `optixAccelBuild` API throws an error when the property to get compacted size is passed in
without the `OPTIX_BUILD_FLAG_ALLOW_COMPACTION` flag set. This is not currently hit
because `background` is always true (set in `mem_alloc`), but would become an issue once that
is sorted out, so fixing it now to be safe.
OptiX always uses record-all behavior for transparent shadow rays, but did not check
whether the maximum number of hits exceeded the shadow hit stack. This fixes that.
transform_direction() can't handle parameters in constant address space.
Creating a local copy of the parameter satisfies the OpenCL compiler.
CUDA and CPU compilers should be able to optimize this away I hope.
In transform_motion_decompose, successive quaternion pairs are checked to be
aligned such that their interpolation is rotation through the shortest angle
between them. If not, the first in the pair was flipped. This can cause
problems for sequences of more than 2 quarternions, since flipping the first
in a pair might misalign the previously pair, if unlucky.
Instead, this change flips the second in the pair, which is safe when
iterating forwards.

This patch adds support for the OptiX denoiser as an alternative to the existing NLM denoiser in Cycles. It's re-using the same denoising architecture based on tiles and therefore implicitly also works with multiple GPUs.
