Blender Git Loki

Merge branch 'usd-importer-T81257-merge' of https://gitlab-master.nvidia.com/omniverse/blender into nv-usd-importer

- first impression

USD import: apply root transform to merged prims.

Fixed logic to identify root objects to work correctly
for objects that represent merged prims.

GPencil: Ensure camera switch is done

GPencil: Minor corrections

GPencil: Avoid 2D conversion for Camera mode

Cleanup: refactor shader sorting to support it for more kernels later

Cleanup: pass full kernel name to integrator state macros

So we can make this dynamic.

Cleanup: make shader raytracing a node feature flag

Cycles X: adapt AO/bevel node implementation to new code

Still not actually rendering through.

GPencil: Remove duplicate parameter

GPencil: First try to bake animation with Camera reproject

Merge branch 'master' into override-recursive-resync

LibOverride: refactor recursive resync.

We need to re-evaluate what needs to be resynced after each step of
processing overrides from a given 'indirect level' of libraries.
Otherwise, recusrive overrides (overrides of linked overrides) won't
work.

Note that this should not change too much in practice currently, since
there are other issues with recursive overrides yet.

Also, checks (CLOG errors) added show that some ID (node trees) seem to
be detected as needing resynced even after beig just resynced, this
needs further investigation still. Could be though that it is due to
limit currently set on nodetrees, those are always complicated
snowflakes to deal with...

Cycles X: Remove unused denoising flags from KernelFilm

GPencil: Convert curve objects to bezier strokes

Create buffer utility methods for copying/filling rects

CMake: Remove unused WITH_CYCLES_DEBUG option

Cycles X: Cleanup OptiX Curves API flag

- Use proper boolean prefix
- Log as a human-readable boolean
- Add description for Python property

Cycle X: Make OptiX debug flag runtime

Allows to enable OptiX module debugging without having special build
of Blender.

Note that depending on compilation flags on developer environment this
could affect render times.
