For correct results these must have been set already when the depsgraph was
created and evaluated, so all dependencies have appropriate resolutions too.
For particle we no longer backup and restore the viewport particles to avoid
overwriting them during render, as copy-on-write solves this for us. Even
without COW particles seem to work ok.
This also removes the particle simplification options based on camera. This
was never used much and only available in Blender Internal.

The new constraint is slower and not backward compatible, but should
be better, especially in the damping side. The new constraint also
has a different valid range of the damping coefficient, and a limit
implementation that bounces instead of making the object stationary.

The issue was mainly visible when copy-on-write was enabled. This was forcing
lots of meshes to be freed from multiple thread, causing all sorts of race
conditions in Gawain's VAO code.
OpenGL resources seems already to be doing deferred deletion, need to do the
same for CPU side arrays.
Better fix for T54457. It seems Debian compiles OpenVDB without ABI 3
compatibility, while Arch does enable it as is the default in the OpeVDB
CMake build system.
So now there's an option that the distribution can set depending on how
they compile their OpenVDB package.
- Undo that changes modes currently asserts,
since undo is now screen data.
Most likely we will change how object mode and workspaces work
since it's not practical/maintainable at the moment.
- Removed view_layer from particle settings
(wasn't needed and complicated undo).
I left a flag to quickly debug if something is wrong.
But now that everything uses shader, it seems to be alright since a shader
is always set active before drawing.
This allows us to specify a the number of vertices to upload to the gpu.
This is to keep the same allocation on the System Memory but send the least
amount of data to the GPU/Driver.
- See `--log` help message for usage.
- Supports enabling categories.
- Color severity.
- Optionally logs to a file.
- Currently use to replace printf calls in wm module.
See D3120 for details.
Roughness baking previously defaulted to 1.0 for all diffuse materials,
now we also bake roughness values of Oren-Nayer and Principled Diffuse.

Use C++11 threads when available, and native critical section on Windows.
Later on we can remove pthread code when C+11 becomes required.

Random numbers for step offset were correlated, now use stratified samples
which reduces noise as well for some types of volumes, mainly procedural
ones where the step size is bigger than the volume features.
