6d4d7c7ca3 Cycles: reduce number of synchronizing object prints.
Do it only for meshes/curves since those are potentially slow and need user
feedback to see things are not stuck. For object instances and lights assume
it's fast enough.

Printing too much can have a performance impact on slow Windows command
prompt or when logging complex scene renders.

cae89a6889 Python/ViewLayers: add object.hide_get/set(), and optional view layer parameters.
These new functions control the per view layer object hiding state, similar to
the selection state. All these object state checking functions now also optionally
take a view layer to use instead of the active view layer.

Fixes T62062.

6e53fdc18f Cycles OpenCL: Motion Blur Compile Directives
When using preview rendering through a camera or final rendering
the `scene.render.use_motion_blur` was not respected when building
the compile directives.

This patch will when building the compile directives check if
motion blur is enabled at all. This should lead to more efficient
kernels when no motion blur is needed.

0edd93effb Fix inconsistent/broken Cycles object visibility for instances.
Object visibility is now handled by the depsgraph iterator, but this API
was incomplete as it made no distinction for visibility of the object itself,
particles and generated instances.

The depsgraph iterator API now includes information about which part of the
object is visible, and this is used by Cycles to replace the old custom logic.
Cycles and EEVEE visibility should now be consistent, which unfortunately does
means some subtle compatibility breakage for both.

Fixes T58956, T58202, T59284.

e58c6cf0c6 Cycles: Added Cryptomatte output.
This allows for extra output passes that encode automatic object and material masks
for the entire scene. It is an implementation of the Cryptomatte standard as
introduced by Psyop. A good future extension would be to add a manifest to the
export and to do plenty of testing to ensure that it is fully compatible with other
renderers and compositing programs that use Cryptomatte.

Internally, it adds the ability for Cycles to have several passes of the same type
that are distinguished by their name.

716e138a1b Cycles: Automatically detect HDRI resolution by default and use non-square sampling map
The automatic mode checks all Enviroment Texture nodes and picks the largest image's resolution.
If there are no Enviroment Textures, it just uses the old default.

Also, the sampling map now isn't limited to square shapes. The automatic detection uses the exact image size,
the manual UI option now halves the value to get the height.

A default aspect ratio of 2:1 makes sense since this is what most HDRIs use.

5505ba8d47 Cycles/Eevee: Implement disk and ellipse shapes for area lamps
The implementation is pretty straightforward.

In Cycles, sampling the shapes is currently done w.r.t. area instead of solid angle.

There is a paper on solid angle sampling for disks [1], but the described algorithm is based on
simply sampling the enclosing square and rejecting samples outside of the disk, which is not exactly
great for Cycles' RNG (we'd need to setup a LCG for the repeated sampling) and for GPU divergence.

Even worse, the algorithm is only defined for disks. For ellipses, the basic idea still works, but a
way to analytically calculate the solid angle is required. This is technically possible [2], but the
calculation is extremely complex and still requires a lookup table for the Heuman Lambda function.

Therefore, I've decided to not implement that for now, we could still look into it later on.

In Eevee, the code uses the existing ltc_evaluate_disk to implement the lighting calculations.

[1]: "Solid Angle Sampling of Disk and Cylinder Lights"
[2]: "Analytical solution for the solid angle subtended at any point by an ellipse via a point source radiation vector potential"

b89f2276e5 Implement duplicator viewport/render visibility options
This allows a duplicator (as known as dupli parent) to be in a visible
collection so its duplicated objects are visible, however while being
invisible for the final render.

An object that is a particle emitter is also considered a duplicator.

Many thanks for the reviewers for the extense feedback.

3abe8b3292 Rename any instance of scene layer or render layer in code with view layer
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.

* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started

Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.

Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

9ad2c0b615 Depsgraph and collection enable/visibility
Iterate over invisible objects too, so lamps can still lit the scene.
Also, now you can use a collection to set an object to invisible, not
only to visible.

For example:
Scene > Master collection > bedroom > furniture
Scene > View Layer > bedroom    (visible)
                   > furniture  (invisible)

The View Layer has two linked collections, bedroom and furniture.
This setup will make the furniture collection invisible.

Note: Unlike what was suggested on D2849, this does not make collection
visibility influence camera visibility. I will keep this as a separate
patch.
