Users can change the group collection visibility in the outliner
when looking at groups.
Regular collections on the other hand don't have any special visibility control,
if you need a collection to be invisible during render, either don't link it
into the view layer used for F12, or disable it.
This includes:
* Updated unittests - update your lib/tests/layers folder.
* Subversion bump - branches be aware of that.
Note:
Although we are using eval_ctx to determine the visibility of a group collection
when rendering, the depsgraph is still using the same depsgraph for the viewport
and the render engine, so at the moment the render visibility is ignored.
Following next is a workaround for this separately to tag the groups before and
after rendering to tackle that.
Tests were broken since e8c15e0ed1.
We now get view_layer from window, not workspace, since the same workspace can
have a different view_layer depending on the window scene.
You could still create groups as before, with Ctl + G. This will create a group
with a single visible collection.
However you can also create a group from an existing collection. Just go to
the menu you get in the outliner when clicking in a collection and pick
"Create Group".
Remember to instance the group afterwards, or link it into a new scene or file.
The group and the collection are not kept in sync afterwards. You need to manually
edit the group for further changes.
All depsgraphs are sharing same object state for now, which means doing set
scene evaluation after main scene evaluation will override all modifications
done by the main scene.
This is an incomplete test since we cannot check for the
depsgraph selection value with the current API, nor can we
see if the relationship lines are being drawn.
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.
