to the source files.

Enables the `bpy.ops.cycles.denoise_animation()` operator again and modifies it to support
temporal denoising with OptiX. This requires renders that were done with both the "Vector"
and "Denoising Data" passes.

This add support for rendering of the point cloud object in Blender, as a native
geometry type in Cycles that is more memory and time efficient than instancing
sphere meshes. This can be useful for rendering sand, water splashes, particles,
motion graphics, etc.
Points are currently always rendered as spheres, with backface culling. More
shapes are likely to be added later, but this is the most important one and can
be customized with shaders.
For CPU rendering the Embree primitive is used, for GPU there is our own
intersection code. Motion blur is suppored. Volumes inside points are not
currently supported.
Implemented with help from:
* Kévin Dietrich: Alembic procedural integration
* Patrick Mourse: OptiX integration
* Josh Whelchel: update for cycles-x changes

Thanks to Michael (michael64) for identifying the solution.

The issue was that the `object_is_geometry` method was used in two different
contexts that expected the function to behave differently. So a recent change
that fixed `object_is_geometry` for one context, broke it for the other context.
The two contexts are:
* Check if a "real" object can contain a geometry to check if it has to be tagged
for sync after an update.
* Check if an object/instance actually is a geometry that cycles can work with.
I created a new `object_can_have_geometry` method for the first use case, instead
of trying to adapt the existing object_is_geometry method to serve both uses.
Additionally, I changed it so that a BObjectInfo is passed into `object_is_geometry`
to make it more explicit when this method is supposed to be used.

The issue was that some geometries were not synced again even when
they changed. This commit adds a map that keeps track of the geometries
that need to be updated when an object has changed.

Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.
For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
