This is a workaround, but a proper solution requires significant changes to
ray intersection in the kernel.

Looping over all primitives for every object is really slow, so this patch avoids that by moving
the necessary assignments inline with the primitive merging done for every geometry.

Emission values should not accumulate beyond one frame, only during the adaptive steps of one frame.

|
This patch will add some compiler hints to break unrolling in the
nestled for loops of the voronoi node.

Work around what appears to be a compiler bug, just changing the code a bit
without any functional changes.

Fixes issue with flow and effector objects which were not being used after resuming a bake job.
This issue has been reported in T75729 and T75758.

More concise return types for cache import functions and general cleanup.

Saving noise cache files is handled in fluid.c.

Ensures that there are no enclosed holes between an obstacle and the domain walls.

cycles
Caused by rB00466e756e33.
While that commit sounds logical, Cycles uses is_updated_transform() to
detect updates.
Now introduce is_updated_shading() and use that on top.

Was happening when only partial subset of callbacks was specified.
The reason was that there was a callback to specify edges sharpness
but no callback to specify vertex sharpness, so the special case for
non-manifold edges was not run.
Fixes T75697: Multires in simple mode doesn't work correct on a plane

This reverts commit 1a3928f33c and 1a3928f3. This is not working stable
with some Wintab implementations, so reverting for now. This leaves only
the Windows Ink changes for 2.83.

CMake: `WITH_CYCLES_DEVICE_OPTIX` did not respect `WITH_CYCLES_CUDA_BINARIES` causing the optix kernel to be always build at build time.
Code: `device_optix.cpp` did not count on the optix kernel not existing in the default location.
For this to work, one should have before starting blender
1) working nvcc environment
2) Optix SDK installed and the OPTIX_ROOT_DIR environment variable pointing to it which is not set by default

Some Wintab drivers report a zero length queue, this causes an unplanned never ending loop.

Currently in fractal_noise functions, each subsequent octave doubles the
frequency and reduces the amplitude by half. This patch introduces Roughness
input to Noise and Wave nodes. This multiplier determines how quickly the
amplitudes of the subsequent octaves decrease.
Value of 0.5 will be the default, generating identical noise we had before.
Values above 0.5 will increase influence of each octave resulting in more
"rough" noise, most interesting pattern changes happen there. Values below
0.5 will result in more "smooth" noise.

Rather than using the last state of the tablet, we now query the history of
pointer events so strokes can follow the pen even if Blender does not handle
events at the same rate.

It's not used by Blender anymore and it's unreliable since this state really
only makes sense associated with events in a particular order.

No functional changes yet, this is work towards making CPU and GPU results
match more closely.

Issue was that the noise simulation was trying to bake with a minimized domain size (adaptive domain initializes domain with size (1,1,1)). Similarly to the base resolution bake, there should be no noise baking happening at those domain sizes - a domain at this size is considered empty.

Make sure that noise uses the unaltered velocity grid. This is particularly important once external velocities get added to the velocity grid.

For a real-world distortion the payload is quite uniformly
distributed across scanlines. Surely, in the corners more
iterations of minimizer is needed, but that happens in threads
without scheduling overhead.

Need to communicate available number of threads to the camera
intrinsics implementation, otherwise default value of 1 is used.
Must have been single-threaded for a very long time.

This refactor cleans up code for the Manta file IO. It also improves the cache 'Replay' option.

Refactored the caching system so that return values are no longer ignored. The aim of this refactor was to make the caching more robust.
