Gathers information about object geometry and textures. Very basic at
this moment, but need to start somewhere.
Things which needs to be included still:
- "Runtime" information, like BVH. While it is not directly controllable
by artists, it's still important to know.
- Device array sizes. Again, not under artists control, but is added to
the overall size.
- Memory peak at different synchronization stages.
At this point it simply prints info to the stdout after F12 is done,
need better control over that too.

There is no reason or justification to have helper functions as
class methods: they do not depend on anything in the class itself.
There are probably more cases like that.

Allows to catch enumerator values which are missing from being handled.
Also use `const char*`, no need to construct string just to throw it away.

While changing the shading normal is a great way to add additional detail to a model, there are some problems with it.
One of them is that at grazing angles and/or strong changes to the normal, the reflected ray can end up pointing into the actual geometry, which results in a black spot.
This patch helps avoid this by automatically reducing the strength of the bump/normal map if the reflected direction would end up too shallow or inside the geometry.

In the outliner, right click > view layer > set indirect only. This is
like clearing camera ray visibility on objects in the collection, and is
temporary until we have more general dynamic overrides.

In the outliner, right click > view layer > set holdout. This is
temporary until we have more general dynamic overrides, but helps
Spring production for now.

It's not necessary anymore since we assume it's always high quality.

This increases stack memory usage some, and ideally we'd support a dynamic
size. But this is quite difficult on the GPU and hopefully 32 is enough even
for very complex cases.

Was only visible when doing command line, since it was happening due to
cache-free policy which was aimed to bring memory usage down.
The issue is that if object with particle system is used as a nested
duplicator multiple times, it will only generate children first time,
and after that its caches are freed. After that duplication system
can not generate any instances, since the path cache is lost.
Now we delay caches free to after all objects are synchronized, which
ensures all instances are generated.
This will increase a memory peak a bit during object synchronization
time, but overall it shouldn't be that bad, since memory footprint
after synchronization will stay the same as before this change.
The ultimate thing to do here would be to drop the whole dependency
graph away, but this will require:
- API on engine side, to inform it to drop the dependency graph.
- Changes in Cycles report system to NOT use evaluated scene to get
scene name (evaluated scene will be gone with dependency graph).

This is a physically-based, easy-to-use shader for rendering hair and fur,
with controls for melanin, roughness and randomization.
Based on the paper "A Practical and Controllable Hair and Fur Model for
Production Path Tracing".
Implemented by Leonardo E. Segovia and Lukas Stockner, part of Google
Summer of Code 2018.

The Properties->World tab had no Viewport Display panel. The world color
itself was hidden when the 'use_node_tree' was enabled.
Also renamed the World.horizon_color to World.color as it has nothing to
do with the color of the horizon (old BI feature)

Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

- Logical use of fields since they define type information.
- Avoids using ordered-dict metaclass.
Properties using regular assignments will print a warning and load,
however the order is undefined.

No longer needed after Blender Internal removal and Eevee replacing the
Cycles GLSL shading nodes.

Internally it's still mostly named lamps, though some modules like Cycles
were already calling them lights.
