Depsgraph itself is still created fer the whole scene rather than for a
single layer, this is to be addressed next.
The storage for those dependency graphs is in scene, but now it is a hash
indexed by layer. In the future we can extend hash key to include extra
information (workspace? window?).
This fixes the issue for the Draw Manager, but for Cycles this is still not
working. The iterator bpy.context.depsgraph.duplis seems to be correct though.
* Fix saving a multiview render from the image editor giving invalid files.
* Fix failure to load multiview images with a single view per part.
* Fix loss of multiview metadata when saving/loading a single view.
* Fix Z-Buffer writing option for single layer EXR not being respected.
Multiview EXRs are now always handled as multilayer internally, significantly
reducing the amount of code.

The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.
The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.
Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.

We now initialize iter.valid as true as part of the main iterator (and manually
when using via Python). And we don't even bother setting iter->current to NULL
if it's invalid. Let's stick to using iter->valid only.
This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
This is a lots of changes, but they are boiling down to a simple API
changes where we are no longer relying on implicit usage of scene's
depsgraph and pass depsgraph explicitly.
There should be no user measurable difference, render_layer* tests
are also passing.
The legacy algorithm only considers two adjacent points when computing
the bezier handles, which cannot produce satisfactory results. Animators
are often forced to manually adjust all curves.
The new approach instead solves a system of equations to trace a cubic spline
with continuous second derivative through the whole segment of auto points,
delimited at ends by keyframes with handles set by other requirements.
This algorithm also adjusts Vector handles that face ordinary bezier keyframes
to achieve zero acceleration at the Vector keyframe, instead of simply pointing
it at the adjacent point.
Original idea and implementation by Benoit Bolsee <benoit.bolsee@online.be>;
code mostly rewritten to improve code clarity and extensibility.

This fix enables the usage of bbones easing parameters for edit and pose mode seperately. This allows animators to take advantage of the functionality and may eliminate confusion as the parameters now behave similar to other bbone parameters.
Note that splitting the parameters between the modes effectively creates a new parameter set. Blend files of previous versions do not contain this information and will have the values set to 0 on load. As it broke backwards compatibility for pose mode values anyway, I also took the liberty to rename the easing parameters in some places for consistency (which breaks edit mode values).

If an object is in any visible collection, the object will be visible.
This behaviour has changed in 9ad2c0b615.

This moves background images out of the 3D viewport,
to be used only as camera reference images.
For 3D viewport references,
background images can be used, see: D2827
Some work is still needed
(background option isn't working at the moment).
This would break if using preview in VSE. We now use the scene engine
not the workspace engine.
That said we could have the preview engine defined as part of the sequence strip
as we had for draw modes in the past. But this is a separated topic for a
separated patch.
This issue in particular was introduced in e4f2b2be26.
Note: VSE preview is still broken in two cases:
* If you have Eevee as the engine in the Scene of the Scene strip.
* If you use Clay, save the file, and re-open.
Objects from set scene gets flattened out to the active scene depsgraph, so it
is a big question why do we need to build dependency graph for set scenes.
Steps to reproduce were:
* Open Blender, create a new scene
* Go back to initial scene, transform object
* Switch back to newly created scene, change operator settings there
* Should cause a crash (at least with asan)
Should behave like 2.7 now, that is, switch scene back to where
operator was executed.
